The Clapper was a popular gadget in the 80’s and 90’s. It let you turn appliances on and off just by clapping. This can be pretty useful, but it has some limitations. First there is the problem of loud noises accidentally turning the lights off. Also, you can’t control multiple outlets independently of each other. […]

Lacking of proper development board always poses huge resistance for me to jump onto a new MCU. Even with the most prototyping friendly DIP packages, wiring a programming header onto the breadboard is both troublesome and unreliable. Things become worse when the MCU is an AVR. There is absolutely no way to mount a 2×3 0.1in pitch

MCUs offer a very wide range of Ethernet connectivity choices. With most applications demanding Internet connectivity, it’s more likely than not that your next MCU-based design will need some type of network connection. Whether your next design is a sensor that needs to consolidate and communicate data over an Ethernet link, a network-connected security camera

Back when I was only starting to dabble in electronics, I needed a project that would meet the following requirements: simple to make; original (i.e. done entirely by myself from scratch); containing a microcontroller; and maybe the most important of all, useful. I’ve had enough devices I assembled just to dismantle the whole thing a

My through hole, home etch friendly version of the surface mount Fab ISP, which is based around the USB tiny ISP AVR ISP Programmer. The new USB tiny ISP drivers also has support for Windows 8 This design uses the ATtiny84 microcontroller instead of the larger ATtiny2313 of the USB tiny. Read More: ATtiny84 USB tiny AVR

Chlorine damage a gasket on the robot and cause the shorts of the electronics embedded. It is obviously out of warranty, and the manufacture does not send me any information to repair it, moreover a new board will cost me more or less like a new robot, cause I’ve to sent it to a certified

Several months ago I noticed the Attiny88. It has several more I/O than the Atmega328, with an extra Port A and PC7. And unlike most of the other At tiny series, it has real SPI instead of USI, so libraries using SPI don’t have to be re-written. At just 86c for qty 1, it is

In a bid to bring affordable solar technology to the market by 2017, IBM Research and Airlight Energy (Switzerland) have partnered to produce a solar parabolic dish that can concentrate the sun’s radiation by 2,000 times and convert 80% of it into useful energy. The system is said to be able to generate 12 kW
