Commodore Amiga 1000 Low Pass Audio Filter Hack
kinmami Oct 24,2022
It allows using the Amiga 1000 audio filter correctly as like as Amiga 500 etc.It is an adapter for CIA 8520 U6P.The circuit requires just 0.1uF ceramic capacitor and the CD4066B CMOS Quad Bilateral Switch.A jumper selects audio filter to be enabled according to CIA status or disabled (Amiga 1000's LED dimming).When Enabled, low pass filter and LED switch on/off/dim automatically.When Disable, low pass filter is always inserted into audio circuit even if the LED does dim low/high.A 4-wire connec...

MegaWang 2000 Turbo Edition - Audio hardware with all video layers
Piper Oct 14,2022
Modular audio and video hardware for retro machines like the Commodore 64. Designed to use 74 series TTL through hole ICs available back in the 1980s, something you can solder at home from parts or order ready assembled.This project started when old retro arcade hardware was being discussed. In the back of my mind was the often fabled "Mega games" by Imagine Software which were planned to use extra hardware on the Spectrum and Commodore 64 to augment the machine's capabilities. Since this hardwa...

STM32 SPI Communcation and Data Sent
electronicguru0007 Oct 13,2022
SPI in STM32F103C8Comparing SPI bus in Arduino & STM32F103C8 Blue Pill board, STM32 has 2 SPI bus in it while Arduino Uno has one SPI bus. Arduino Uno has ATMEGA328 microcontroller in it, and STM32F103C8 has ARM Cortex- M3 which makes it faster than Arudino Board.STM32 SPI ProgrammingThe programming is similar to the Arduino code. The same <SPI.h> library is used in programming STM32F103C8. It can be programmed using USB port without using FTDI programmer, to l...

PicassoIV CDMix
MastaTabs Oct 12,2022
This little gem was developed at Village Tronic Computer back in the day by a service technician, after the audio circuits of the PicassoIV was chiseled in stone and had some short comings.Using this board you can listen to CD and Amiga audio through the PIV audio output at the same time.The design is proven and working.

SOLAR Bank Version 2!
Arnov sharma Oct 08,2022
Hey Guys what's up?This is the SOLAR BANK which is essentially a power bank that has an onboard solar panel.This SOLAR BANK can provide stable 5V output for powering XYZ stuff like an Arduino board or a Raspberry Pi Board. It can even be used to charge Smartphone or in my case an IPAD.It contains a 3.7V 1200mAh Li-ion Cell that is connected to a Power Management IC Setup that takes the 3.7V from the cell and outputs 5V.IP5303 IC is being used and it's a well-known PM IC that is widely used in sm...
