TTL 6510 Computer
Dec 17,2025
IntroductionI know, this is not the first TTL CPU/Computer and not the last. But I got interested in designing my own TTL-CPU after a friend showed me his "Ben Eater 8bit Computer" setup. I really liked the educational part of it, even though the CPU is very limited. I then looked into the "Gigatron - TTL microcomputer", which is a clever RISC-like design.Both CPU designs had not been modeled after any existing CPU architecture. Because of its nature, the Gigatron doesn't even req...

How to make simple Variable HIGH VOLTAGE Power Supply
Pavleski Dec 11,2025
 High Voltage Power Supply is usually understood as a device that is capable of generating a voltage of several kilovolts, or even tens and hundreds of kilovolts. Most often, these power supplies give a certain voltage at their output. When experimenting with high voltages, we almost always need a variable value of the generated high voltage. There are several ways to achieve this, and in this project I will try to implement and explain all of these ways in one device. Of course, I will try...

Crop Link --
Soni Nov 20,2025
Crop Link is an extended and upgraded version of our earlier project, LoRaMessenger 1.0, a long-range wireless communication system designed for transmitting message strings over LoRa. While LoRaMessenger 1.0 validated the concept of long-distance LoRa communication, it also revealed several limitations in range stability, noise performance, and real-world deployment in open rural environments. These learnings formed the technical foundation and direction for building a more capable, scalable, a...

Commodore 64 Power Supply Replacement Switchmode Regulator Board
Solajic Nov 13,2025
This PCB is a switchmode regulator replacement for Commodore 64 power supplies with part number 251053-11, submarked as BV 830 810.01/II, manufactured by Ismet. This is the so-called "Wedge" model, but with "sharp edges", contrary to the more common "Sloped Wedge" model.Please note that at least two other types of power supplies bear the 251053-11 model number, the fully potted brick (which usually came with the C64C model) and a "sloped edge" model which is submarked as BV 830 810.01 ...
