ESP32-S3

Be careful, not all ESP32 S3 are the same! You need the XIAO ESP32-S3 (not the PLUS version!) from Seeed Studio, which looks like that:

You preferably need the unsoldered version, some come with pins soldered, which would not work for a left hand, and work but take more space on a right hand.

Five servo motors

This might be trickier than it looks because it seems there are very different qualities available under identical model number.

Be careful: it's a jungle !

The same reference may have slightly different features. For example, the wires can come out at a bottom corner, or from a side 5mm from the bottom.

The ones I have used with some satisfaction are labeled MG90S (not sure what is the difference with MG90), they have a 180° rotation (not 360°) and look like this:

You will need 5 of them.

BEWARE: These ones below won't fit for now, but they seem pretty common, so I'll try to make changes to support both kinds:

BEWARE (again), the blue servos with the same dimensions, labelled SG90, seem really weak by comparison.

Strong wire

I have used Nylon fishing mono-wire on my prototype.

It's said to resist to 22Kg loads, diameter is 0.6mm.

Nylon fishing wire is by far the easiest to install, because it's a bit rigid.

I have tried braided wire, on another prototype, which is less rigid but hellish to install and obtain the correct tension, to the point that once finished I removed it and used Nylon again.

Wire blocker crimp beads

They are metal beads you squeeze on the wire to block it.

They look like this:

I don't think there are several sizes for that kind, but they mostly need to be just big enough for two wires before you squeeze them.

Two metallic pulleys

The thumb wires need to be guided by one small pulley each. I used the V623ZZ model whose size is 3x12x4mm

Screws

You will need three M3*12 hex screws and nuts to assemble the servo platform and the palm

You will need two more M3*12 hex screws, nuts and washers, to hold the two thumb metallic pulleys in place.

You will also need 3 M2*6 philips screws to secure the electronic board to the palm & platform (the picture shows 4, but you need 3)

The screws that hold the servos in place are provided with the servos.

Electronic board
