RetroShield 1802
Lunde Aug 20,2019
Adds an 1802-processor to your Arduino Mega 2560 today, run all of the latest 1802-based software available! Note that most of the software available may or may not be from the 70s, but the fun is still as up to date as ever... provided you like computers!Based on software and designs by Erturk Kocalar, this Arduino Mega 2560 shield adds a supplemental 1802 processor to play around with. There is a small prototyping area to the left side that you can use to a button, an extra blinking LED becaus...

How to build an isolated digital AC dimmer using Arduino
PCBWay Team Aug 20,2019
AC loads are everywhere around us because at least home appliances are supplied with the mains power. Therefore, we always face the situations that we want to have full control (dimming) over an AC load such as a lamp, a motor, vacuum cleaner … etc. We should know that controlling an AC load is not identical with a DC load. So we should use different electronic circuits for this purpose.The figure-1 shows the mains sinusoidal wave with the frequency of 50Hz (sometimes 60Hz). To build a dimm...

Kawaii Hearts <3<3
Natalia la la la Aug 05,2019
Kawaii means cute in Japanese we based this project on KawaiiTech logo. This pendant is so cute, easy to assemble and re-program which makes it totally customizable, it can be worn as pendant or even earrings. We liked black solder mask with HASL finish, maybe you wanna rock ENIG?The board is based on ATTINY85 charlieplexing 6 LEDs and powered by a CR1220 battery. BOM:1 ATTINY85 SOIC 86 0805 LEDs we recommend ultra bright1 cap 0805 0.1uF1 CR1220/12225 battery holder, footprint is made for 2894 b...

AVR Programmer W/High Voltage-328pb v1.5
Mackey Aug 04,2019
AVR programmer that supports 5V, 3v3 boards/chips, as well as high voltage fuse management.The board contains three independent sketches: ArduinoISP, AVR_HighVoltageSerialProgrammer, and NOR Flash HexCopier. See AVRMultiSketch for the source code and the OSX app I wrote to load three sketches onto the board, selected by the buttons on the board, without modifying the original sketches.I've also designed a few accessory boards:ATtiny85 ICSP (DIP or SOP8)NOR Flash (Winbond...
