![]() ![]() This represents the electrical core of the anchors that are mounted on 3 corners of the room. ![]() Here’s what a single one wired up to a battery and motor looks like. All the others had their own weird problems. ![]() Long story short, I ended up fabricating a bunch of these before finding out that the H-Bridge was being used the wrong way.Īnother rather infuriating bit is that even though all these boards look more or less identical, only one of these four seemed to successfully work. Since it’s meant to drive a motor, I’m using the H-Bridge. It operates on 3.3V, so both it and the ATTiny44 are made to be run on regulated 3.3V power. Modules for the nRF24L01+ half-duplex tranciever chip are sold for less than $1, which means it’s ridiculously cheap. These nodes use the Nordic Semiconductor nRF24L01+ modules to communicate with each other. I’m putting networked nodes in 3 corners of the room driving DC motors which control spools of fishing line which will position an end-effector. For the final project, I’m making a room-scale crane. ![]()
