Qube, not an Arduino clone

I'm sorry, but PIC wins...they're like 15 cents a chip!

What allows the everyday user to tinker with microcontrollers, IO, interrupts, serial communication, and even analog readings? How about individual modules that add the ability to communicate over bluetooth or add LCD support? If you were thinking Arduino, you would be wrong. It's actually [Nilok's] Qube, which at first seems like another Arduino clone however the Qube is based on PIC - not AVR. … [Read more...]

SparkFun stencil and solder paste class notes

stencil

Hobby electronics manufacturer SparkFun has started offering various classes at their Boulder, CO facility. [Landon] has been attending as many as possible and posted about his experience during their Stencil and Solder Paste class. Solder paste is used when manufacturing boards with a reflow oven. He took quite a few pictures of the process and posted notes and audio. He says it's definitely … [Read more...]

(I'd put on some gloves before handling that much lead paste) They top it off with some alternative ways of doing reflow work. My favorite has to be the target hotplate method. It's a nice introduction if you're interested in doing SMD work to save money and … [Read more...]
