13 Brilliant Projects using Raspberry-Pi, ESP32 & more on PCBs!

hi everyone welcome back to our channel in this video we'll discuss some unique and interesting projects built on pcbs so let's get started number 13 our first project is a Pi computer with a mechanical keyboard powered by Raspberry p Pico and designed by Peter he calls it Max Sanger it contains many retro video games for you to enjoy but the best part is the backlit keyboard giving you a PC gameplay like experience what's even more remarkable is the PCB on which all the components are soldered making the project very thin and to place the screen he made a cutout in the PCB and protected it with a coverboard this solved two things for him first it kept the display firmly in its position and second it reduced the overall thickness of the project number 12 this board can convert any ordinary oven into a Reflow oven Yes you heard that right made by maker mcoy and powered by esp32 S2 this is one of the best projects we've seen so far he took an ordinary oven removed the oven's original control knobs and replaced it with this custom designed PCB board the PCB includes sensor inputs outputs buzzers and other SMD components the OLED display and three push buttons give him the option to use the oven as a standalone device but it can also be programmed to work with apps on your smartphone he also added an acrylic glass over the control board that not only adds a layer of protection but it enhances the oven's overall look number 11 next we have a macro keypad made by Saleem it contains 12 keys and two rotatory encoders that keep all his shortcut keys in one place instead of soldering the keys directly to the PCB he placed them on the outer Mount and soldered them from the other side it increased the mechanical stability and reduced the stress on solder joints at the bottom he added RGB LEDs covered by a transparent plastic that scatters the light and gives the keypad a floating glow look these keys are customizable which means you can modify each one according to your needs number 10 this this is a tracking system or more precisely a Geo fencing made using a GPS module with this virtual fencing we can track whether any object's outside or inside the boundary the transmitter transmits the GPS coordinates of the target object to the receiver upon receiving these coordinates are uploaded to the web server which can be viewed by entering the web address as this project uses Laura modules no internet connections required based on the target's location the status gets updated in real time to convert your project ideas into a highquality PCB you need an experienced manufacturer and that's where next PCB can help with their top quality standards and fast delivery time they ensure that you get the best PCB at your doorstep the ordering process is easy visit their website upload your Gerber files select the parameters according to your needs select the shipping pay the required amount and you're good to go check the description for more details number nine this PCB might look tiny but it can control any IR device with the help of the internet Tech SMS calls it the universal IR Blaster and it contains an esp12 module along with some resistors and transistors the five LEDs on the board are enough to transmit the signal in any direction and control a device but if these are not sufficient you can add two more LEDs to it before using it as a remote you'll need to configure it with the cadeo mobile application and assign the function of each button in the app number eight next on the list we have a small arcade machine tiny Cade based on the at tiny 85 microcontroller it runs on a coin cell which is enough to power an LED and a 0.96 in OLED display it comes pre programmed with certain games that can be played with the three push buttons on the PCB but it could be reprogrammed with other games youer tried to reprogram this board and uploaded different games on it he also used it to display some text and in the future version he aims to add his self-made game to it number seven our next project is a gestured controlled robot it uses two RF Nano boards this Dev board is a clone that offers offers at mega328p and nrf24 L1 Wireless modules in a single package one of them's connected to a gesture sensor that controls the robot and acts as the transmitter the second one's connected to the robot car which acts as a receiver both the circuits are made on custom pcbs to reduce the number of wires this spot uses a track chain instead of Wheels which provides better traction number six programming a microcontroller using ICP headers can be difficult if they're soldered to a circuit board or if it's placed in tight spaces to solve this issue Jeremy made a custom ICP Pogo pin adapter for at tiny 85 it's not a one-of-a-kind jig kit but what sets it apart from others is that it positions the icsp connector in line with the Pogo pins this makes it easy to determine where each pin is going and allows you to swap the single standoff screws to the other side if needed this makes the at tiny 85 programming process simple number five this Project's dedicated to every tech nerd out there a clock that displays time in the binary number system it's a great way to practice your programming and electronic skills the project consists of a circular PCB with multiple LEDs soldered to it the LEDs at the bottom represent hours the LEDs in the middle section represent minutes and the LEDs at the bottom represent seconds the clock's powered by a Raspberry p Pico module soldered at the bottom number four this is a flexible PCB ball made of 100 LEDs and watching it Glow is a treat for the eyes these LEDs are divided into 10 arms each LED on the balls positioned by hand and soldered using a makeshift hot plate and a Reflow gun while making such pcbs there are some rules to keep in mind like not using traces with corners or edges as they tend to crack when bent the same goes for ground planes which tend to break when flexed the trickiest part that you might face would be soldering the arms of the bottom circle to the top one number three programming an esp32 cam board is a bit of a tedious task because we have to press the reset button which is provided on the back side of the board to make this process easier techs built this esp32 programmer we just need to insert the esp32 cam into the programmer connect it to the USB upload the code and voila the esp32 cam is programmed without the need to press the reset button apart from the esp32 cam we can also program other boards like esp32 chip and Arduino Pro Mini with without removing or adding any components from the programmer this board's compatible to work in 3.3v logic as well as 5V logic number two you might have used different displays in your project but have you ever thought of stacking them together sha came up with the idea of making a three-dimensional display using 10 transparent oleds a custom-designed PCB and a feather microcontroller he stacked all the displays together which gives a regular 2D image and additional depth you can also create your own custom 3D animations with this project sha gives us a glimpse of what the future displays would look like number one running open CV on an esp32 cam is not that easy but by following this project you can do it the esp32 cam captures the image and uses canny Edge detection with the open CV library in real time once the code runs the screen displays the ttgo demo for 3 seconds after that RGB mode grayscale mode binarized mode and Edge mode are executed repeatedly The cany Edge detection requires the most computational power hence the FPS of the displayed image is low but on average it displays the image with 6 frames per second drop a like
