Although the most popular fidget spinners seem to be the ones with 3 sides, for this project I decided to go with a 2 sided design. A 2 sided design would enable me to use 2 cr2032 batteries wired in parallel for power, one on either side of the spinner....
First try to put the zip ties into the holes, above and below the LEFT_SERVO and RIGHT_SERVO rectangular markings. The zip ties are supposed to go diagonally across the Servomotors. Put the zip ties loosely just enough to lock them in place. The zip...
Ok, so I can finally say this has transitioned to product stage. A few customers achieved and now manufacturing of the 1st 125 production units has started.Along the way I did some testing on 150Ah deep cycle batteries and improved the s'ware to handle...
The plan is to use a small AVR microcontroller (ATtiny14?), K-type thermocouple with an Adafruit MAX31855 breakout board, an SSR, and a Python GUI linked to the ucontroller to have a stable temperature controlled hot plate that can have programmable...
The easiest way to control the treadmill is to simulate button presses, the original MCU will take care of changing the speed and stopping/starting the treadmill.So the Arduino code should look like this :Loop{check serial port for commandsif we receive...
Four Raspberry Pi 0s were selected along with four brass spacers. The spacers were meant to add some distance between the PCB holder and the computer. This allows solder joints and other things to pass under it without putting pressure on the board....
Wires attached to the light rings were too short in most of the cases. This was an error in judgment on my part from moving through the project too fast. The previous wires also had no consideration for color coding, another lapse in judgment. New wires...
I will be out of town next week so I decided I might as well design and order some TinyFPGA Programmer boards now so they might be ready by the time I get back. It's a very simple design. It follows the breadboard circuit closely while...
Find a 13.5” x 13” x 3.5” box made of durable yet flexible material (preferably plastic)Using the following SID (System Interconnected Diagram), lay out the surface electronics depending on the shape/size constraints of your surface...
I'm currently traveling in France and showing the module to other hackers and others ! However I've always used the demo board with my lab PSU so I need a cordless, portable power supply. I designed the module to accommodate 6V, or 4× alcaline cells,...
I just received the boards and did a thorough quality check. Thank you to the sponsor @Fredrik Högberg ! It seems that it could be made on bakelite :-) Notes for later : PCB trace widths : OKClearances for mounting holes : OKClearances for...
Full details will be added here eventually but for now, here is my plan for the main components: Teensy 3.2 (From PJRC, see https://www.pjrc.com/store/teensy32.html).128x96 pixel OLED screen (From Adafruit, see https://www.adafruit.com/product/1673).8x...
1. Place the top down 2. Put the navigation buttons in place 3. Put the PiPod board on top (make sure you've put in the screw between the RPi and PCB circled in red) 4. Put the side buttons in place and make sure they have a loose fit. If they are too...
After the problems I had with the last batch of boards, I went back to the drawing board. Well, back to hackaday.io anyway, where I found #Business Card Gamepad, which I figured might be a solution to my USB Type-C receptacle woes. I found...
The boards and components all arrived, so today I sat to solder everything and test the module. Whilst soldering the components on, I realized I had gotten the pattern wrong for the After soldering all the components on, I used the ST-Link part...
