The instructable created by me will help you to build a huge memory capactiy which will come in handy for many projects and measurements. The memory card is suitable for multi-usage and can be way more realaiable in comparison to flash cards and other type of soft memory. The life span of those CMOS EPROM’s …
I recently bought The Energy Detective (TED), a pretty inexpensive and friendly way to keep tabs on your whole house’s electricity usage. It’s a lot like having a more featureful version of your utility company’s power meter, sitting on your kitchen counter. It can estimate your utility bill, and tell you how much electricity and money you’re …

This is a mutli-mode clock project based on attiny2313. it employs a 8×8 led matrix as display. with the limited resolution, this 12 hour clock shows time in 6 different modes. The circuit employs row and column multiplexing to drive the leds, one row at a time, this gives a 12.5% duty cycle when “sets” of leds (8 of them …
I’m currently building a temperature logger for some guys doing a research in biology. Tried to make it as small as possible, with temperature sensor that can be crammed in small space. Since the first revision slash prototype of the device was incredibly simple to make …

The Micro Kart 644 is a mobile device that provides additional capability to the traditional RC car experience. Allowable functions are recording multiple tracks, which consist of all user controls sent to the car over a 25 second interval, and replaying the tracks so the cars replicate the movements made during the recording. In addition, …
