EEVblog #1155 - Mailbag

hi welcome to everyone's favorite segment mayor bag Monday let's get into it this one comes from Simon Simon as in eevblog forum moderator Simon who's also got Simon's electronics who by carries some eevblog products including the new 121 multimeter so what's he sent oh cool thank you very much original and handmade in London at time art awesome fantastic thank you very much it's now face-tracking on Marty terrific thanks Simon awesome make what is it that is I thought that was a photo it's not Wow it's a it's an actual like it's a drawing M Kadam there you go wow that's I wish I had the skills I really do we show had the artistic talent to draw paint something like that'd be awesome thanks Simon Wow let's stick that down hi to all my Swiss viewers and thank you very much for Krishna - Christian Mulford Mueller mala for sending not this one in and apparently you're not allowed to use Crocodile Dundee knives on it bugger that as I was warned that it is delicate and I am not to use the knife to open up it I don't know where my other stuff is it's all I've gots the knife so I'm gonna be very careful tongue at the right angle that's the ticket tongue at the right angle and one eye I'm gonna see the trauma it's got like it's huge Pettit things what else I was gonna break the the bubble zoom it's delicate it's very nicely fact yeah they're the risk there was busty maze not very satisfying this is more satisfying my speed sheet a bubble wrap can reuse that oh it's really moist packing this ship and stuff what is it Oh ah ah silly no Road ah to mr. fusion oh that is gold thank you very much it's not an original of course but it is the same model that they used on the DeLorean apparently it's a coffee grinder from the German company crops modelled 2 to 3 for those playing along at home from the 1970s he could not find a white one so I bought an orange famous and painted it white ah oh yeah geez you did a good job beauty oh yeah I can see some orange on the bottom there you go fantastic for apparently it was used in alien there you go I'm gonna have to watch alien awesome movie and of course there's the there's the one with Marty fantastic and Christian runs a YouTube channel up play with junk awesome I'll link it in down below check it out oh let's go straight to the pool room now this one I don't actually know who it's from and it didn't have my ol bag on it if you gotta send stuff in p.o box 7 9 4 9 book Emile's New South Wales 2 1 5 3 Australia not Austria um and yes you can't put that crazy Aussie bloke on if you want does get to me and they know me at a local post office um yeah if you don't put my Oh bag on it cuz I order so much stuff and get random stuff from supplies and stuff if it hasn't got mailbag on it I mean Kay I'm gonna probably unless it's obviously looks obviously like a mailbag I'm gonna open it and that's what I did in this case but then I realized it was you know I didn't go any further because I realized it was obviously a thing so um what do we have it's a fashion keyboard just what I always wanted want to be fashionable and it is got some sticky feet no idea what these things are got a whole bunch of those it's a crow pie crap crow pi by Ella crow awesome thank you very much la crisi miss Ella crow who sent me this and it's a is a development board I can read on the back equipped with a 7-inch display that can help you learn Raspberry Pi in an easier way with crow pie not only can you learn basic computer science but also practice in programming and complete numerous electronics projects can improve your knowledge and ability in hardware blah blah blah built-in 7-inch touchscreen not all-in-one or what sort of jazz so it's groovy it's the advance kit fantastic I know how much it costs but there's a few of these things around now like you know raspberry pies and like putting them you know I think I'm out right no far Nels have have one element14 still call them far else and I think Jake I have one and electronics probably and they like attaching like like bundling together like screens and other sort of stuff oh look at that it's got film for our protection and their bundle in them isn't that Jessi carry it around in your little crow pie pie crow pie I can't do it anyway Oh controller alright let's check it out up close well isn't that sexy huh like fake carbon fiber and everything crow Paul that's like Chrome oh let's have a look seriously it's really quite professional look at that wow that is sex on a stick wow what an assortment of stuff I've got ourselves a Raspberry Pi over here what one does it come with it isn't there a new one it's a model three B+ thingamabob there you go good enough for Australia oh look look they've even provide a little right angle audio think nice attention to detail wow I don't show you could find that somewhere and Aliexpress you know a right angle instead of the cable coming out here it didn't fit but that's fantastic I love how they've incorporated the PCB into this case and they've got standoffs yeah there's nothing on the bottom so obviously they've had the the standoffs integrated into the case and it's got a whole bunch of stuff well it's without reading the manual can just look around here what do we got got an RFID tag reader fantastic we've got like like a joystick e button thing not sure what's doing up here it's not labeling maybe it's just some miscellaneous circuit required for interfacing got some dip switches got to have dip switches we've got a little matrix keyboard fantastic got a relay terrific we've got a knot relay in an opto coupler and a screw terminal interface what's that is that that's it well we've got a touch sensor but what's that is that some environmental sensor D th11 yeah I think it's one of those the mystery temperature things is it one of you know humidity temperature sensor or whatever Oh little tilt mercury switch I'm assuming that goes to it does that go to an infrared module why do they have the pins why don't I have the infrared LEDs I'm not entirely sure anyway you are servos ultrasonic transmitter and receiver looks like we've got some sort of motion thing is that like an accelerometer you know dip you usually don't get those in a dip 16 sound beautiful yeah we've got a buzzer and a speaker and oh and a oh no oh that's a yapper that's a passive infrared sensor nice and vibration all these are sync em the segment address decoder nice and of course we've got our seven segment display with a time so you can do a clock or whatever we've got a lead matrix I don't think that's an RGB one I think it's just a regular one tiny little breadboard in there a couple of miscellaneous stuff around there which you don't interface with and state LEDs on all of your outputs for your Raspberry Pi but how do you interface with the outputs of your the i/o and your Raspberry Pi I don't I assume they don't come out to the breadboard know that breadboard looks like it's just stuck down so maybe it's like are they all fixed does it go off to everything else I'd like to be I'd like to see that you know come off in a pin header so I don't know what's anyway don't know it's doing there and your regular Hitoshi 2 by 16 LCD and it's crop' i've version 1.00 and power protectors well it looks like we've got some external power oh that looks like a power switch for the whole thing and a USB interface well that is thoroughly impressive but it want to be for 260 Yankee bucks and of course I've got our while screen up there what is that like a 8 inch screen 7/8 inch high yeah my immediate thought is like okay I mean it's got all these cool and they're all this cool stuff you can play with but like a where's the interconnects I would have liked to have seen like a whole bunch of you know cables like jump flying leads that you could jump over to the breadboard and you know stuff like that and connect various stuff off I guess or this is a hard wired into the various IO of the Raspberry Pi and there's our HDMI to down in there I like that and it's buggering off under the board comes up here over this protected cable here and they've done a real good job here oh it's got a camera there you go I think it it must know the cameras not just camera in there but not sure there's no cable hooked up mmm-hmm anyway it's available in black and blue and they extol the virtues of haha fastener and hinges made of iron iron man yeah anyway it's a very nice little ah blurb that they've got with this thing and this is just the QuickStart guide so there you go you got the Raspberry Pi pin out touch sensor heart there you go that's where they're connected to yep they are hard connected which is a bit of a shame I would like to have seen you know the ability to put jumper wires and all that sort of jazz on there but still it's it's very impressive and that's what I've got I've got one of these fashioned keyboards cool and I'm going to assume that it is all pre-programmed and ready for me to pair up so I'll give it a ball and it's all about the material that comes with it as well and you got a crow pie lessons PDF I'll linking all this down below and like a 21 different lessons so we'll take a quick squeeze at that as well but and the price for this thing is 230 a Yankee bucks if you want shipping to Australia that's pretty pricey at 47 woah Yankee bucks yet again so mm-hmm and by the way I noticed that it doesn't actually have doesn't tell you what the voltage is there or whether or not to you know you've got to assume it sent a positive but they don't tell you any details yeah that's a bit of an oversight all right you smart young kiddies are probably screaming at me these are minecraft blocks you cut them out and you fold them and yeah okay and these aren't little stick on feet or whatever these a little RFID tags you stick on the bottom of these and then you sit your cube on there and you play your Minecraft all right let's pair it up I got my funky wireless keyboard and moosie and let's see if we can pair it with a hey yay come on Raspberry Pi we're gonna be in like Flynn welcome to the Raspberry Pi does desktop where we're going we don't need roads it says hey cheese enabled and the default password for the PI has been changed this is a security risk please log on as pi user run blablabla okay we're in and the great thing about this is this is going to be great for sagan who is seven but he's already into our scratch coding he hasn't done it easily he's only done it on you know pcs but he's never done it on a Raspberry Pi so apparently Ella Crowe provide scratch examples for all this sort of stuff so you can interface in your scratch as a programming language like a sort of like a flowchart a block diagram e programming type system and apparently can run scratch programs and here it interface with all these cool sensors this is kind of Sagan's gonna have fun with this so it comes installed okay you've got minecraft Pi Mathematica cool anyway we got scratched and scratched to I don't know the difference between scratch - I assume scratched - is big and better than scratch so anyway I don't know I wonder if it actually comes with the examples or not I don't know pre-installed but you can certainly they're all part of the lessons and stuff like that you can download from Ella Crowe so I think you're really gettin you 230 Yankee bucks worth in this thing with all the educational stuff scratch geez the screens pretty small like you know but for young kids it's gonna be fine no looks like they don't have them pre croak croak oh yeah crow pie Python cuz smoke I don't think it's uses Python scratch it may in the background I don't know anything about it and we're connected up to the Wi-Fi no problems because it's just a Raspberry Pi and here we go we've got the CRO PI lessons with scratch 2.0 and you can control the vibration blinking all that sort of stuff so all the documentation is here it's like maybe it is on it somewhere but it would have been nice if it all came pre-loaded but of course you can just go to the website and download it it's just a small thing sorry if the video is horrible on this but anyway because it's a standard Raspberry Pi and a scratch I believe comes with support for Raspberry Pi or at least it you know when it's on the Raspberry Pi is going to more blocks here at an extension and Pi GPIO io nice so that should give us access to yep the GPIO stuff so we can actually start like accessing the individual io pins and then talk to the sensors right well I'm following the example here and I don't know anything about scratch so I'm a dummy so scratch with GPIO is unfortunately it's it's not the best if you're starting from scratch I'm here a week we scratch then like it's not the best example like it just you know I can't get it to do this sort of stuff it doesn't tell you which panels do what in here so it's not really a like a beginners tutorial to scratch so to speak like I can't get this you know I can get it to mate with this variable here I've created the variable lead but I can't get the GPIO to come up with lead and things like that doesn't tell you how to run it it doesn't tell you which what this panel does to it doesn't tell you what this over here does doesn't tell you you know any of that doesn't tell you where to find them like in here I sort of had to you know figure that out myself it's not hard you know hey just click around several times you can find all the different stuff but yeah it's not the best and absolute beginners from scratch tutorial oh I kind of figured it out on my own look you to run it apparently you just click in here there you go led I don't have to do that variable because I'm not using any the lead variable because I couldn't figure out how to do that anyway GPIO pin 18 is and you'll see light up down here who is it up see it's flat why is it flushing like that look why is it I don't know what's going on there but apparently that is connected turns on for one second I don't know it's flushing anyway and yeah I got it go in but yeah I don't think it's the best beginner you can't decide I think you could give this to a beginner and expect them to follow this example precisely and just get it working without any drama although the documentation looks good the but just not as thorough as I'd like it especially for a beginner scratch programmer didn't press her record button just done the whole spiel anyway look you get a bunch of stuff with it you get the two controllers to play your minecraft thingy and you get a remote control and the extra RFID you get touchscreen pin because yes it is a touchscreen thing you know the screwdriver as well for the that's a nice touch for the screw terminals and there's the infrared receiver there you just plug that into those pins don't know why they didn't have it sold onto the board but I guess you want to orient it and move it around different angles and some button caps and stuff like that ah Raspberry Pi heatsink we should stick that on headphones and we get a servo and DC motors so that you can just play around with those so that's actually very impressed like the whole thing is very impressive I think does the experimental kit come with the keyboard and the mouse and everything else I'm not sure but anyway it's I love the concept of this thing it is absolutely fantastic it's actually cuted reasonably well but as I said I would have liked to have seen like the software like boot up and like can't let the manuals on there and it just or automatically opens or something like that and the instructions as I said for the scratch not exactly the best for the first timers but all that stuff can be improved but apart from that like a package like you carry it around with you you know kids can like sort of you know carry it around on holidays on school wherever you're doing and take it over to your friend's house and have a play with it it's it's great it's got a huge range of senses so I'm very impressed that one I think it it's pretty much kiss the thumbs up that's a real nice bit of kit and I think they got like 40 bucks off at the moment so you can get it for like 200 bucks I believe but it's a little bit pricey but yeah it's a nice well put together kit this one's from Wong wing ho thank you very much Wong wing or is it wing Wang ping ping what hanging Hong man she Li Lu Hao sing Ching Gong Yi GU what I have to show you this not spoil it that's just insane what is that address is nuts so is it a joke e eBay you know $2 fighting novelty gadget a lot of people send those in yeah two dollars delivered on eBay or is it actually I think find out cheese kind of well she's heading tonight but a USB cable what is that that's that's 3d printed check that out what my earth is that there's got lint in there okay we've got a whole bunch of number laser-cut printed lot numbered acrylic things don't know they don't go on there maybe like I got something to do with this oh it's a Kickstarter it's a Kickstarter from and yes it's a company name is it eight by eight by eight item calm or one word with X's in the eighth I'll link it in down below um thing I assume what yeah we know thank you very much um it wasn't a random eBay thing we sell awesome gadget we manufactory autumn awesome gadget we designed awesome gadget welcomes more quantity wholesale so there you go they're like a design and manufacturing company if you want him to do it is it a Dixie cheese like anyway look it's a LED light-up ring thing it's kind of was futuristic in the 70s maybe that was their vision of the future you know we will have this would be a sort of some sort of a fancy memory storage device some sort of computing or some sort of energy device or something like that so that's a bunch of acrylic sheets ace presume it just lights up different colors okay let's check out his stuff this is the Museo it was a Kickstarter apparently and it's like a wobbly Tower thing and it looks like it's got a once again 3d print that looks 3d printed to me the base of it and you stick some USB in there and I suspect it's going to light up so hello ah my battery bank helps over to my battery bank on hey whoa psychedelic man that's yeah that's what I expected I expected to flash in time with music so you sit that on your your bedside table your coffee table or whatever in it I'm gonna peel the top off that looks pretty dagi but that's kind of funky it's obviously got different modes there we go that's peak hold peak hold it's a peak peak peak peak bake Oh Oh nope hey hello hello world anyway it's got all these different modes there you go cute and this thing had me baffled for a bit until I figured out what it was now you can see that there's LEDs in there and that's what I couldn't figure out like why and then we've got these sheets here there's as I said they have all these digits on them and you break them out and it's you're gonna these I got a plug into there and it's gonna form a a fake lead-based Nixie tube display with the different each LED lights up here to go into using this as a light pipe to light up the segment it's a novel idea but I can't help but think on now I'd give me the real Nixie but jeez that one's a bit how you doing in it jeez seven little things on it does it doesn't need to have that does it no anyway um here you plug them in and it's going to be a poor man's Nixie to display so I haven't plugged them all in yet cuz this actually had quite a bit of work to do that you got to peel them all off and stick him in but that's the idea there you go it's just like and it's just like a Nixie tube it's gonna have the different layers now and oh my how to focus on fix focus Jesus but you can see the concept is just like a regular Nixie tube how they have the different layers in there and they light up and yeah there's a bit of like interference from the ones in the front of the ones at the back light up and stuff like that but yeah it's designed to simulate it so let's let's plug it in and see if it does anything for this one and digiti you can barely even see it I'm gonna turn the lights out sorry but I'm not impressed it's actually better to one 0 z 9 at the back 8 is sort of hard the ones at the back of hard to see it's counting down and yeah I'm not sorry that's a fail it just it just ain't the same but I'll give that IE for originality though so thank you very much one wing ho for sending those in check out the web site they do have like up to I think twelve by twelve LED matrix RG b matrix cubes and lots of fleshy fleshy light gadgety things cool but all my viewers in Hong Kong in particular mr. ping uh winning name um once again it didn't have my Oh bag on it but I like opened up couldn't took a quick peek and went that's gotta be my obey I'm presuming sorry anyway have a look there is a note no it's not notes and invoicing and mr. ping it's great nice to know someone his first name was ping female ping fantastic what are we got Wow lots of little boards we got got a breadboard with a camera then a screen don't know what don't know what's doing there it looks like it's just an interface - it looks like it all this joins together alright let's have a look at all this it's really documentation with this there's no documentation it's a sip heed development kit board thing with absolutely no documentation I don't have to check my email and um check the website and see what's what or we can spare it up huh turns out this scipy sip heed board and the module here the Internet of AI it's an artificial intelligence module it's the first 64-bit artificial intelligence module apparently and it's on IndieGoGo it's got three days left they've met their goal I think this is just some demo platform or something they've put together so USBC on there let's power this thing up so yeah it's designed for edge computing artificial intelligence module for edge computing I have no idea what computing is sure someone all enlighten me alright let's power this up whoa whoa there we go I'm dead oh yeah what's it doing was it it's so I'm doing some sort of image thing sorry I'm some sort of image thing I don't get it it's not voice is it anyway it's the damn doc okay damn I'm sad Ann's dog fair enough boot switching a couple of switches on there but it's not like it's obviously doing something I don't know what oh I think what it is is it's a spatial microphone array I'm on this side of the camera these mics here look these are little microphones around here so if I move to this side of the camera over here yep let's follow me around and if I go over to here like this yeah it's following my voice so yeah that's cool it's a spatial microphone array and it's look it's you know there's like a density kind of you know map telling us where it's coming from there you go that's kind of cool so I'm sure there was a lot of processing that went into that microphone one and here's a camera module presumably doing a thorough you presume the new things under there somewhere and then you chips anything anyway let's pair it up and see what we get up demo1 oh hello hi and yeah all right so it's like if that's real time what is it oh it's facial tracking me it's a facial tracking it's now mouth tracking that's adult anyway yeah cool so like an artificial intelligence module for the image processing sound processing all that sort of stuff so I'm sure you know that requires a lot of a lot of grunt to do that on a little microbe is we know we know chicken dinner and this rather convoluted looking one again we've got a camera got a screen and we've got some servo motors so it's kind of a tilt I presume it's going to track track me as I move around let's have a look Oh welcome to makes fee max fee hello yeah yep we've been very well welcomed I expected like it to do a similar sort of image processing thing but use the motors to track and object or track a a thing so there's a little as the dev board down in there it doesn't seem to be welcome so touch hello any buttons on it nope it's a little microphone in there don't know but um oh it's a disappointment come on do something so I'm not sure there's much else I can do with that except uh link to the IndieGoGo down below if you're interested in like a like a high grunt process in it's a jewel call risk v thingamabob and AI insides and probably got some artificial intelligence some maybe some dedicated hardware or something in it or something like that but yeah it's a risk v RV 64 GC 400 to 600 megahertz and it does some like you know some fancy real-time grunty processing of audio and video and stuff like that so getting down below check it out I'm sure there's a lot of people who are would be very interested in such a like a like a high-speed you know artificial I don't know the artificial intelligence side of things does it have like you know software or routines or something to you know handle all this fancy stuff I don't know check out the IndieGoGo down below thanks for sending that in so if you like my Oh bag please give it a big thumbs up so it always helps a lot as always discuss down below and you can check me out on patreon and all that sort of jazz and yes I got the one 21 multimeter back in stock and I crypto donations and you know all that sort of stuff still so um I learned much I'm hopefully trying to get my t-shirt store my teespring store integrated with YouTube so maybe it'll pop up on this video or below or somewhere I'm trying to get the integration working on that happening again so to get my t-shirts back through teespring so I've got a she'll all this stuff to stay in business catch you next time [Music]
