Cheap laser cutter arrives pretty busted up

Wednesday, August 13th, 2014

Like many others we have succumbed to the urge for a cheap laser cutter. What started as a $200 purchase quickly doubled, but that's still a fraction of the cost of an expensive one. Why do we what it? That's a not very well hit secret. The ubiquitous blue Chinese...

Random Saturday electronics blog

Saturday, August 2nd, 2014

Replacing a NIC with something hopefully high quality from Intel. Noticed that Intel uses a healthy mix of 0402, 0603, and 0805 components. Especially capacitors. Not sure if this is due to cost vs capacity, or if smaller, harder to place components are used sparingly as needed. From experience typical...

Taxi death on way to Shenzhen factory visit

Monday, July 28th, 2014

Took a taxi about an hour to the manufacturing area of Shenzhen, Bao'on. When we got in it seemed like there was something wrong with the car or driver, 3rd and 4th gears seemed nonexistent. Initially I though maybe we should swap cabs, its a long trip after all. But...

Chinese New Year in Shenzhen the world electronics capital

Friday, January 31st, 2014

Shenzhen wasn't a town 30 years ago, it was barely a village. Almost nobody is from Shenzhen, people come here to make money and send it to family in other parts of China. Over the Chinese New Year, that two week period when you can't order from Seeed Studio, tons...

Another day, another project, another fixup..

Wednesday, January 22nd, 2014

We designed a microcontroller board for a power supply, but somehow we forgot to add the oscillator to the circuit. We thought it was enough to add two nets called 'OSC1' and 'OSC2' to the schematic... Why can't Eagle cope with that automatically?! The lovely photo was taken with an...
