CHAMPAIGN, Ill. — Though they be but little, they are fierce. The most powerful batteries on the planet are only a few millimeters in size, yet they pack such a punch that a driver could use a cellphone powered by these batteries to jump-start a dead car battery – and then recharge the phone in …

A collaboration of biologists, engineers, and material scientists at Brown University has found that jagged edges of graphene can easily pierce cell membranes, allowing graphene to enter the cell and disrupt normal function. Understanding the mechanical forces of nan toxicity should help engineers design safer materials at the nan scale. PROVIDENCE, R.I. [Brown University] — …
For relatively small (less number of pins than ATmega328) projects, AT tiny series, ATtiny45 or Attiny85 are good choice in terms of its physical size (8-DIP or 8-SOIC) and low power consumption. There are many ways to program it. One of the popular device is USB tiny ISP and DASA. Both of them work very …
The Product: Sol-X developed the GDB to be the best open source prototyping platform on the market and we intend it to replace the Arduino Uno® as the preferred high-level prototyping environment. It is up to 40x faster, 70% smaller, has integrated high power drivers (capable of handling 12x the current), with more flexible Input …

If you have embarked upon electronics projects in the past, there is a good chance you have already encountered this common component and soldered into your circuit without second thought. Diodes are valuable in electronics and serve a variety of purposes, which will be highlighted in upcoming steps. First, what is a diode? A diode is a …
The purpose of the project was to create an external USB audio card, which could be able to: 1) serve as usual external USB audio card with headphone/line output and audio line input 2) can transmit the digital audio data at relatively long distance (20m -100m) 3) can receive and process the digital audio data …

The MAX14777 quad SPST switch supports analog signals above and below the rails with a single 3.0V to 5.5V supply. The device features a selectable -15V/+35V or -15V/+15V analog signal range for all switches. Each switch has a separate control input to allow independent switching, making the device an alternative to opto-relays in applications that …

This work includes, GTP USB (not plus or lite) . The schematic, photos and PCB have been developed by PICMASTERS based on some valuable works done before. This programmer supports pic10F, 12F, 16C, 16F, 18F,24Cxx Eeprom. Unfortunately, it works with only Winpic800 v.355. We have successfully tried it with some pics; PIC18F252, 18F2455, 18F2550, 18F2520, …
What was that? A What’s-a-Maja-Thimagig? Yep – One of those! This Instruct able extends my Arduino Ethernet controller to control a set of up to 6 relays, but that’s not the neat bit. The neat bit is that there is a web based state machine in the At Mega chip so that the relays will …
This instruct able fully describes building a PWM driver to control four LEDs from one small Microchip 12F609 board. The original design was called the “Kemper LED Lamp” and I sold a few lamps to several brave folks through my web site. However, I’ve come to discover selling small quantities to a few folks is …
