A weblog focused on interesting circuits, ideas, schematics and other information about microelectronics and microcontrollers.
Cheap and excellent MP3 player based on VS1002 MP3 decoder, PIC18F45x microcontroller and LCD display from Nokia 3310 cell phone.
You can connect an old cellular phone add-on camera to the Internet using an ATmega32 microcontroller and an ENC28J60 Ethernet controller. The compact system’s hardware can fit in a matchbox.
A great thing: software-based MP3 decoder for dsPICs, published under GPL.
Two constructions based on IR signalling.
WinUSB a generic driver for devices that don't fit a defined USB class. The driver was introduced with Windows Vista and is also usable on Windows XP systems. The driver is not usable on earlier Windows editions. The driver supports control, bulk, and interrupt transfers.
is a .NET host application for accessing devices that use the WinUSB driver. Each includes an example INF file to match the device's Vendor ID and Product ID to a device interface GUID. There are two variants - VB.NET and C#
