Control Pi-Plate With Spark Core

The ppDAQC board from Pi-Plates.com is an inexpensive yet powerful solution for expanding the input/output capabilities of the Spark Core. And since Pi-Plates are stackable, it is a simple task to scale up the I/O capabilities of a single Core. All that is required for connectivity are the four SPI signals (signals A2-A5) as well as a single digital output (D6). Power can come from the Core or from the ppDA ...

It’s wasn’t so long ago that RC transmitters, at least ones worth owning, were expensive pieces of gear. Even more recently than that, the idea of an RC transmitter running an open source firmware would have been considered a pipe dream. Yet today buying cheap imported transmitters and flashing a community developed firmware (if it didn’t come with it pre-installed to begin with) is common place. It’s not m ...

Because of I often use protoboards to test out if a new idea works in practice. I do not use breadboards anymore because I pretty much use only smd parts and I hate the connection problems and high parasitics that breadboards have. So the Flower ProtoBo ...
