UpGrade Hot Plate
New day new project, I decided to repair and Upgrade my hot plate iX5 with new OLED screen the old one is simple segment screen new plat biger than the old one, add encoder, add new microcontroller (esp32 C3 Super mini) add PID control, Timer ...Next step 🪜 build new 3d printed box designe based on the old but bigger and maybe add web control with heating curve graph
Here I am turning my 128x32 OLED into a monitor at midnight
I used an esp32 and a custom c# program to send monochrome image data of my screen over USB serial 🔥
ESP32 ALARM SYSTEM
just for fun project 🙂 , alarm system based on Esp32 for the core system & esp32 supermini for wireless keyboard, first step done system interface, add micro sd module for hosting server & storing Event, add spiflash for storing password (crypted), default parameter (reseting system by default if needed) and other critical parameter. the alarm system can turn normaly even if micro sd is faulty (micro sd just to storing the interface gui system, the system core inside esp32 and copy at eeprom) ,...

First perfboard project
I just recently bought some perf board and soldering stuff and now that I’m on winter break I finally have time to keep learning this stuff. The circuit I made is just an transistor driven led but I made it so by shorting 2 of the pins, you can switch between driving it with an arduino, or by turning it on and off manually with a button. You can also choose between powering it with female headers, or with any wire through the screw in terminals. I mainly did this to learn perfboard and soldering...
JBC Soldering Station
First of all, I would like to thank every active member of this discord server that has helped, special thanks to @robherc , @Taire , toesis and MaderDash.
A couple months ago I started looking for a new soldering iron, when I saw that while there were some promising Chinese models, most of them had design flaws and other kind of drawbacks. Just looking at the prices of reputable name-brand irons made me sick so I decided to design my own. I started my research with opamps, high and low side switching for high power loads (10A at 24V), then moved onto all the details features that the real one has. The soldering is not the nicest, I had no solder paste so I first added solder via my iron and then reflowed it, but by that time too much oxidation was on the surface
Things to do:...
Ardunio bot but modified with first robotics stuff
I'm adding a USB server host and a wireless controller to this to make it a remote control car basically
