A weblog focused on interesting circuits, ideas, schematics and other information about microelectronics and microcontrollers.
The Daisy is a multipurpose sound player for embedded applications. It can be used as a standalone personal music player,as the sound for an art project, in a kiosk, as a museum tour guide, in a toy, or anywhere that high quality embedded audio is desired. It uses MMC or SD flash memory cards so storage size is unlimited. It has several interface modes for either human or machine control.
The I2C LCD Back-Pack is a small(ish) PCB that can be plugged onto the back of an LCD so that you may control it over an I2C bus.
This device monitors household power usage and logs it to an SD card.
Using an IR LED as a proximity sensors.
An ARM Cortex development board with a lot of capabilities.
Really powerful autoranged capacitance meter based on PIC16F873. It means users does not need to adjust the range settings. The measuring range is quite large, from 5pF to 2600uF.
AVL stands for Automatic Vehicle Location, which is accomplished by means of a tracking GPS and M2M modules. Actually a small AVL can be used to track any objects, including kids and pets.
This device, based on an Atmel ATMega168 microcontroller can monitor up to 16 DS18x20 thermometers, with a variable logging rate of 5 to 9999 seconds. The data is displayed on a multi-page LCD display for immediate viewing as well as being sent via RS232 at 19200 baud for recording. Data is time-stamped with an optional on-board 1-Wire real time clock.
If you currently have a STK500 development board, you will face a problem because it doesn’t support any of Attiny24/44/84 chips. You have two ways: either buy STK505 adapter which is quite expensive, or develop your own.
This project attempted to reconstruct a functional Apple II emulated on Atmel ATmega32 processors. Due to time constraints, a fully functional Apple II was not produced; however, a working emulated 6502 processor, memory subsystem, and partial GPU was produced.
