Following my review of Ryan Walmsley’s RPi MCB, and my previous review of the RasPi Robot board it only made sense to also assemble and review the Boeeerb MotorPiTX which I also received recently. The MotorPiTX is a multi-function board. It has two A/B motor drivers, two servo controllers, a bunch of headers and most …
It’s been a while since I did any assembly, but I seem to have built up a pile of bits again, so it’s time to break out the soldering iron… First in the queue is the RPi MCB (Motor Control Board), the first hardware product from Ryan Walmsley (the Rastrack guy). This is an interesting …
I have had a kit of parts for a RaspiRobot board in my “to do pile” for a while now. Today I had a bit of spare time so I followed the construction instructions and put it together. Step one was to check I had the right bits. I opened the packet and laid the …

I recently got a comment on my article from 1st February about Soldering a Slice of Pi/O asking for some help in programming it in Python. This reminded me that I have not got very far with this little board beyond checking that the Raspberry Pi could see it. So I decided to see what …

When the raspberry Pi model A was announced a few days ago, I ordered one straight away. With three different models of raspberry Pi now available (or four, if you count the red Chinese variant), working out the capabilities of the board is becoming increasingly important. It’s vital for anyone involved in making hardware or …
