While the LittleBits team shares their brd and schematic files for the parts, there’s no Fritizing files made available.
I’ve started to take a crack at this with the HDK parts and particularly the perf bit:
UPDATE: I fixed the internal wiring on the proto bit. It’s now wired as the module WITHOUT the jumpers. So, if you want to emulate the jumpers that come on the board, remember to jump the male pins with a wire like the picture below:
To be fair, I have orders with both above, but haven’t received any previously fabricated parts, yet… They are due in this month though.
yup, the key is the white soldermask. My kid saw the purple oshpark screenshot and said “that’s not a littlebit”. He saw the white photopaper printed one and said “It’s a really bit now”. I had to let him down, reminding him it’s just cardboard for now
Later this week after a few more touches, I intend on ordering the fab from oshpark. I’ll just have to call them special edition bits
Got the first prototype back from oshpark. Note the tabs on the edges are part of the fab process and I’ll need to cut them off later. Only issue so far is the male side drill holes are a tab too small. I’ll have to check why later. I buzzed the circuit and it sounded good, so next step will be to solder after I widen the holes a tad.
Nice circuitry Shai! It looks good and works ! That’s the goal right there. You might have to solder the tiny directly … (I don’t like doing that either. Or can you put it on the top, but bend the pins upside down?) also I like that sticker you have that identifies the pins - very cool (I have written on the chips with a pencil before, but the sticker is *great.)
@alexpikkert I don’t have a particular project but had some ideas.
Detect a foreign object in a path
Detect a moving object from a distance
There’s all sorts of things you can do when you know the distance of something. Not to mention the use in robotics. I’ll work on some ideas and post something soon. I’ll reply back to that thread you shared too.
