DIY Sensitive STM32 Pulse Indiction Metal Detector (Arduino IDE)
Pavleski May 05,2023
 This time I will show you how to make a sensitive Pulse Induction metal detector which is based on ARM STM32 microcontroller, which has significantly better features than Arduino and is also cheaper. It can detect metal coih at distance of 30cm, and big metal object at distance of more than 80 cm. The positive thing is that you can install an Arduino bootloader on it, after that you can use it as a regular Arduino. This is my first project with this microcontroller and the experiences...

OverEngineered Phone Stand
Arnov sharma May 04,2023
Greetings everyone, So here's something super useful and awesome: "THE OVERENGINEERED PHONE STAND" made completely from scratch by using Custom PCBs and 3D Printed part.Fusion 360 was used to create this phone stand. The main body is entirely 3D printed, with PCBs covering both sides. The PCB contains an IP5303 setup that converts the onboard lithium cell's 3.7V to 5V, which is then used to power 5 RED LEDs that illuminate the entire phone stand.Why were red LEDs used? for no part...

Pinout 20 - IC Wings - A tidy way of connecting to IC Chips, to help with retro upgrades, breakout points or Diagnostics
OVERANGE Apr 17,2023
This provides a way or connecting to Socketed ICs with out having to solder straight onto legs or even bend up legs.Simply cut the strip down to the required size, file the edges smooth and then slide onto a machine socket IC and solder into place.You can either solder on pins for connection test points, or even direct wiring.if your project requires that the IC leg must not connect to the socket below, you can simply cut and file away the sockets leg so it does not make contact.Please note :-Or...

Magic Desk 2 for Commodore 64
Cristaldi Apr 13,2023
An Open Hardware Project to build a 3 in 1 Commodore 64 cartridge, based on Magic Desk 1MB and Universal c64 Cartridge by Marko Šolajić.Due to the low cost and availability of 27c160 EPROMs nowadays, building a cartridge with 2MByte of ROM is easy to do. Furthermore, the 27c160 EPROMs can be 8 bits addressed and, given the amount of pins, being THT is an advantage.3 Different configurationsMagic Desk 16Kbyte configDouble Magic Desk 1MBGMod3 2MB Read Only cartridgeVer. 1.6All infos on https://git...
