My challenge (to myself) was to control two large (brushless) motors via a laptop. Proof-of-concept for a butter-passer’s movement twin tracks. I need clockwise and anti-clockwise control from two motors, in a controlled-fashion of course.
And yea… I managed to do it. As Rick might say, I pretty proud of this bad-boy so far.
Lemme talk you thro it….
White cable – going into the mains (UK) electric supply. 240V, but I’ve limited it, with a 2amp fuse. Those motors run off only half an amp each.
Neutral – Grey wires. straight into the motors.
Live – purple wires, splitting into the tiny brown wires, which go into….
Relay board – my first mistake. These relays switch on a minimum of 8V, so the RPi’s 5V supply is too weak. This relay board must be for an aurdino. Hence, the 9V battery is there the power the relays coils. The relays switch the live power, through the orange wires. One side of the (8mf) capacitor for clcokwise, the other side for anti. Simples!
SSH into the RPi, and manipulate the GPIO pins via Python.
I’ll make a video, depending on interest.November 14, 2016 at 12:59 pm #76970
I am intrigued. also, I need to film from start to finish the shit I’m doing for a project that does nothing.November 14, 2016 at 3:38 pm #76971__eMpTy__Participant

Can your large butter-passer be utilized as a whiskey fetcher?November 15, 2016 at 6:39 am #76975TruggleswickMember
I think it’s main use will be attacking customers. Those bastards that just walk into my shop, uninvited, and annoy me when I’m trying to work!November 15, 2016 at 7:22 am #76976
I just “finished” (still needs work on the joystick bit) my ghostbuster PKE meter. uses 33 LEDs with 4 shift registers, 2 servos, an analog ps2/3/4 thumbstick, and a LDR so it’s more of a dark/light meter than ghost meter. I’ll upload a video/pics after I do a bit more clean up and discover why I shock myself if I try to hold this one part
