SIDKick pico 2350DAC (SID 6581/8580-replacement)
. Jan 28,2026
The SIDKick pico ("SKpico") is a drop-in replacement for the SID 6581/8580 sound chips in the Commodore 64 and 128 computers, and an alternative SID for Ultimate64-boards and the Commodore 64 Ultimate. It also emulates the SFX Sound Expander (FM). It has been designed as an inexpensive alternative to other SID replacements while not making compromises regarding quality. This is the newest variant, the SKpico2350DAC, based on the RP2354 microcontroller (which includes flash storage) wit...

MIDI Interface Commodore C64 compatible with Datel, Passport, Sequential
pastamar Jan 25,2026
This is simple DIY MIDI Interface for Commodore C64. It is compatible with Datel/JMS, Passport, Sequential and has MIDI IN, OUT and THRUThe MIDI standard is selected by jumpers. Jumper setting is printed on the board.It is created based on information presented on following page https://www.neperos.com/article/pp6loj56370b9c3eOptocoupler used in the design is H11L1. (4N35 wil typically not work due to speed limit)I have used GAL16V8D instead of descrete logic to save some space and cost (they ar...

Build a 5-Day forecast Raspberry Pi Weather Dashboard (Step-by-Step)
Pavleski Jan 20,2026
 Recently in one of my previous videos,I introduced you to the 7 inch Elecrow Pi Terminal and how to make an SDR radio with it. This time I will present you with a very simple way to make a beautiful weather dashboard with current weather, 5 day weather forecast and 5 day meteogram graph. The original project and idea are from the given github page (https://github.com/infinitel8p/weather-forecast?tab=readme-ov-file) and all the credit goes to the author of this project.  Recently ...

Amiga 500 6570-036 Replacement
Jan 17,2026
After my Amiga 500 keyboard stoped to work and facing difficult to find a cheap replacement for the 6570-036 CI that I discovered was damaged I decided to create a alternative replacement. Started with a Arduino 2650 to make a pilot and some tests and after some time with the prototype working I did move on developping a board using 1284P. Firmware is still in progress so I can´t provide it.

ESP32 Aneroid Barometer using Squareline Studio and LVGL on CrowPanel Round display
Pavleski Jan 15,2026
 A barometer is a scientific instrument used to measure atmospheric pressure. Rising Pressure generally indicates improving weather, and falling pressure usually indicates approaching wind, and rain. Steady pressure indicates stable weather conditions. In this project I will describe a very simple way to make an Aneroid Barometer emulator. In fact, modern digital electronics are used, with the help of which the functionality of a classic mechanical barometer is 100% imitated. Aneroid barome...
