Greetings, One late night of web surfing I came across some 45 Degree Extension boards. Thinking to myself “Wow!” that’s cool and then I looked at the price…$27.00 before S&H. “Yikes!” I’ve been looking for an excuse to learn Eagle PCB layout software and this was the project I decided to cut my teeth on…”Wing […]

LED Candles have No wax, No smoke, No heat, No mess. ECO BENEFITS Safety: eliminates fire danger […]

Description The LTC®7138 is a high efficiency step-down DC/DC regulator with internal power switch that draws only 12μA typical DC supply current while maintaining a regulated output voltage at no load. The LTC7138 can supply up to 400mA load current and features a programmable peak current limit that provides a simple method for optimizing efficiency […]

Anirudh Sharma, an IT Engineer from Rajasthan Technical University has developed a system that offers non-obtrusive navigation for the visually impaired . Calling it Le Chal (Hindi for ‘Take me there’), Sharma conceptualized and demonstrated the system at MIT (Massachusetts Institute of Technology) Media Lab Design and Innovation Workshop 2011. The Le Chal system comprises […]

Naturally, the Uno does not natively support keyboard strokes, unlike it’s Leonardo brother. Most of Google will tell you you need to do some firmware workarounds and ATMEGA reprogramming just to get it working and the entire ordeal is a mess. If you’re like me, you’ve found that out just after buying one. Here is […]

Wearable computing, e-textiles, soft circuits or whatever you want to call it, is a growing field of applying technology to garments or accessories like bags, shoes or backpacks.  It is a fun and creative challenge which goes beyond just adding LED lights to fabric.  For a primer, you must check out the work of Lynne […]

This is a very odd kind of clock, which can easily be made with simple supplies. To begin the explanation, I would like to say that I have always wanted time to be metric. 5 o’clock would be mid-day, 7:5 would be three quarters (6:00 pm), and so on. This prototype tells deci-days, centi-days, and […]

Extending Infineon Technologies’ OptiMOS 5 portfolio of power MOSFETs are 80-V and 100-V variants optimized for high switching frequencies used in synchronous rectification applications for telecom and server power supplies, as well as industrial applications such as solar, low-voltage drives, and power adapters. OptiMOS 5 devices slash on-resistance by up to 45% for 80-V parts […]

This is a fun project that can be done easily and also cheaply. In this instructable we will explain step by step how to make this beautiful POV clock. Used material: Arduino Uno, RTC modul, ULN 2003, IR diode and IR transistor (used like a sensor, more details in next steps) 4 pushbuttons (for controling […]
