JACC64 16K - C64 Cartridge
b5s4 Jun 28,2025
This is a tested and working projectA simple cartridge intended to hold a single 16K ROM image with power LED and reset switch. This cartridge is designed for M27C128 EPROMs (and compatibles).Larger (E)EPROMs should work, just duplicate the 16K ROM image as many times as is necessary to fill the (E)EPROM.8K ROM images will work but to pair it with an 8K C64 BASIC ROM to make 16K for maximum compatibility but often just doubling the 8K ROM is fineBOM (all THT)1 x 5mm LED (D3)1 x 6mm Tactile Push ...

Snake Game Console MAX
Arnov sharma Jun 27,2025
Hey everyone! Presenting the Snake Game Console MAXThe updated Snake Game Console incorporates two RGB 64x32 P3 matrix panels into a single ultrawide 128x32 display. It uses the same PICO 2 display driver as the previous project, but I designed a new 3D-printed frame to accommodate both displays adequately, complete with integrated handgrips and a D-pad buttons PCB for snake control.We developed the original Snake game by reusing and tweaking code from the previous Snake Game project. The g...

ESP32_Programmer v1.0.0 (validated)
Rey Jun 24,2025
ESP32 Prog LiteThis module was designed to optimize the programming of ESP32 devices in production environments. It emerged as a solution to a common problem: the need to efficiently and cost-effectively program electronic products that don't require a USB port for final operation.The USB problem in productionFor devices that run on alkaline batteries or are programmed only once at the factory, a USB connector and its integrated serial converter, such as the popular CP2102N, represent an unneces...

How to make Simple Offline High Voltage Generator 220V to 60000V
Pavleski Jun 12,2025
  A high voltage power supply is an electronic device that provides an electrical output at high voltages, typically ranging from hundreds of volts to several kilovolts (kV), or tens kilovolts. Very often, DIYers need such a device to perform various experiments, prototyping circuits and tests. Generally, this type of device requires a powerful low-voltage DC source, and then a DC to AC circuit with powerful MOSFETs, which is relatively complex to build, and also expensive. Specif...

String Controller V1
Arnov sharma Jun 11,2025
Greetings, everyone, and welcome back!Introducing the String Controller, a wearable game controller that will transform the way we engage with games. Unlike traditional controllers, this unique approach allows players to operate the controller with their natural finger movements, providing a more ergonomic and simpler experience.Traditional game controllers need constant gripping, which can cause hand strain over time. But do we really need to hold them at all?Our design has a wrist-mounted...

Pocket SNES
Arnov sharma May 29,2025
Greetings everyone, and welcome back! Today, I’ve got something fun and tiny to share—the Pocket SNES, a miniaturized version of the classic SNES controller, built entirely from scratch using Custom PCBs and 3D Printed Enclosure.This project has come a long way. I originally created an extra-large version powered by an XIAO SAMD21 Microcontroller encased in an extra-large Enclosure. I had to print the enclosure in three separate parts and then assemble them together to form a single co...

DIY Low Voltage One Tube 6J1 SW-SSB SDR Radio (Works at 3.7V)
Pavleski May 29,2025
 A vacuum tube radio, also known as a valve radio, is an early type of radio receiver that uses vacuum tubes to amplify and detect radio signals. These radios were widely used from the early 20th century until the 1960s. Nowadays with just one Vacuum Tube and Signal Generator you can make a super simple, yet sensitive and selective Shortwave/SSB Radio Receiver, thanks to the use of PC and SDR processing software. In fact, this project represents a kind of Software-Defined Radio where compon...
