As PCB part placements get denser, it’s necessary to add breakaway panels that add additional board material (edge rails) to accommodate the assembly process. Two parallel edges are required for a PCB to be processed in the SMT line. This is to prevent skewing through the conveyor system. Also, all odd shaped PCB’s must have …
USB OTG (On-The-Go) cable enables for example a simple connection of USB slave devices with a smartphone. As we know, USB communications operates in such a way, that a Master (Host) device (usually a PC) controls all communication on the bus and Slave devices are only able to require attention. Slave devices are all common …

If you have an H-Bridge drive circuit for a motor, you may need a way to monitor the load on the circuit. This circuit is nice because it provides a single output that could be monitored with a microcontroller or other device. The trick is to use current sense amplifiers and measure the current on …
Well-proven graphic displays Bolymin BG series represent a very suitable and cost-effective choice for applications, where we need not only character- but also graphic output. Series BG from company Bolymin belongs to a group of universal displays with an excellent price / performance ratio. Each type contains some of standard LCD controllers, that´s why it …
Invention of a new Open Source mechanical musical instrument Following the « DYI » trend, here comes a musical automaton created by [EricDuino]. This Arduino based autonomous robot is named « Line Follower Organ », « Orgue Suiveur de Ligne » in its maiden language. What’s new with this instrument is that it moves along its partition in order to play …
As you know, the BE-CO-HT section at CERN has been contributing to Kicad for some time now. We see this involvement as a key part of our activities regarding Open Source Hardware [1]. We are also contributing to the adoption of VHDL and System Verilog in the Icarus Verilog simulator, so as to enable cross-language …
Three years back in time, I bought Nikon D3000 DSLR. I started shooting, but the moment I needed remote, came one day (more over night), during on night photography session. I checked all local suppliers, but the prices were high. I ordered one from China. The problem with orders from China is that they take …

The Social Drink Machine involves a fully enabled robotic bar which prepares your dream cocktail, a Facebook application which you use …
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 impossible. Esto se debía principal mente a que cada paso de los motores paso a paso que uso es de 0.9° (400 pasos / rev). Cada …
