Currently revising the design to reduce weight and have bigger wing chord base on advise from DIYdrones with slightly shorter wings.  AUW 1521 Grams Wing loading 14.83 oz/ft²  power to weight 270 Watts per Kg should perform much better than Yellow plane one. I’m changing from the D4023-850 Out Runner Motor to a higher kv Turnigy L3010C-1300kv Tests show significant improvement in static thrust […]

Brazo robot dibujante V2. (Monstruosidad tecnológica) Los resultados del brazo robot dibujante anterior no tuvieron una gran resolución. Mi idea inicial era hacer que pudiera escribir y eso resultaba imposible. Esto se debía principalmente a que cada paso de los motores paso a paso que uso es de 0.9° (400 pasos / rev). Cada tramo […]

VHF FM Aircraft Receiver is a superregenative receiver developed for listening to FM transmitters but also tunes the aircraft band and the top portion of the FM broadcast band. Receives both AM and FM (107mHz to 135 MHz). You can use this receiver with the any FM transmitter. The receiver is amazingly simple using only […]

Taking the two basic concepts of blocks and tables, four graduate students from the Univesitat Pompeu Fabra in Barcelona, Spain, added music to the mix and designed something called the reactable. The reactableis essentially a music synthesizer, and if you hear it played, it sounds similar to a lot of modern electronic dance music. The […]

(Phys.org) —A team of robotics engineers working in the Personal Robotics Lab at Cornell University (led by Ashutosh Saxena) has developed a new way to give robots a context-sensitive way to organize a room. Instead of providing the robots with a map, the researchers instead cause the robot to “imagine” how a human being would use objects in a room and then to place them accordingly.

Hello, and welcome back to another installment in the long-running Top 25 Distributors list, brought to you by EBN and hosted this year by our colleagues at EDN. As you’ll see from the annual list, not too much changed amid the electronic components distribution landscape in 2012. Some companies lost revenue ground, and some gained—some […]

Almost since the birth of amplified guitars in the early 1930s, players looked for ways to enhance the sound of their electric guitars. A huge variety of guitar effects have emerged from their experiments. These include rack-mounted effects, effects built into amplifiers, and pedal effects. While rack-mounted and built-in effects are separate topics, this article […]

AZIZ is an LED microscope illuminator that I designed and built from scratch.  It is designed around a Texas Instruments TLC59116 constant-current PWM LED driver chip, and an Atmel ATTiny1634 8-bit microcontroller. Features include: 64 LED illuminator, comprised of an inner ring of 32 super-bright white spotlight LEDs (25,000mcd) and an outer ring of 32 […]

Advantages of Refurbished Electronics You’ve chosen to think on it and maybe get a little advice. Your environmentally conscious friend tells you that buying refurbished is the way to go. Why is that? By giving their products an update, electronics manufacturers can keep electronic waste out of landfills. Electronic waste is a growing problem worldwide. […]
