A mount PCB for Bosch BME680 sensor (Temperature / Humidity / Air Pressure / Air Quality), made so it stands out of the device case and is less affected by device heating.

Smallest thing I've made so far, with the sensor itself being 3x3mm with 8 pads. If you have a PCB thick enough, the sensor can be soldered on top of it with 4 pins on each side nicely fitting to the traces on the PCB.

Ordinary components are so beautiful close up.

Got really into CRTs a bunch of years ago, figured that the grail project would be to just build a driver for myself, from the ground up. Wanted to make it with entirely off the shelf components, so thats what I did. No proprietary, custom, or obsolete/NRND used. So far still need to work on blanking and more on the software side but I've got pretty reliable performance on the tubes I have right now. Eventually will get it to play oscilloscope music on its own, but haven't gotten there yet.

I arrived home to school and found out, damm it was my favourite

Works every time😂

Went to a hamfest near me and found some fun toys. and numitrons

250€ later...

Got tired of manually turning on my laptop cooling pad(IETS600). So I used a leftover Arduino to tap into the PWM pin of the fan motor. Communicate via USB Serial from a c# program that monitors which app is open, and if its a game, will send the instruction to the Arduino to turn on the PWM pin at whatever speed I want :)

This watch was created with love for those who want to wear a piece of history on their wrist - blending the charm of the past with the tech of the future. Featuring military-grade Nixie tubes and a unique design, it’s a true head-turner !

guys i finished my flappy bird logic ic

i made it on my fone btw

Components so cheap they make you order at least 100 lol

This board of draws a lot of current, and I'm trying to fix it. Starting to identify all the components. Hope someone has use for this info.

I made this charger which has 3 outputs, upto 3A combined 2 USB A output 1 USB C output (iykyk) It also charges LiPo and Li-on batteries. I have massive batteries which burns out this tp4056 module, so I added it with this massive heatsink and the small one on top on the ic. It converts any DC input between 6-28V DC to 5V. I know I didn't add thermal paste cause I didn't have one. But it does the job, I tested it.

I once had the smaller 50 circuits version when I was a kid. And this was my gateway to developing a passion for electronics. Made some cool circuits back then some 20 years ago. But my mom threw it away:( So now I got a myself this bigger version. In your face mom! I feel like a kid again. Ideas for circuits outside the book are welcome!
