Remote (IR) controlled serving robot made from an IKEA trash can. Phase one is tackling the mechanical functions: ball topspin & backspin, auto ball feed, friction wheels. Electronics are at a functional stage but will be continued in part two. PCB in works along with open sourcing the design.

![Automatic Small Part Counting Machine with Arduino | Version 2
I rebuilt my small parts counting machine into a smaller form factor with a better mechanical separator inspired by Rx pill counters. I [used to] sell kits with small parts/fasteners. Counting them by hand is time consuming. I made this robot to do the task.
I consider this endeavor abandoned- but enough people find this video and ask about the design files so everything is open source now.

id love to revisit this. please share what you make. this solution done cheap will help so many people. Automatic Small Part Counting Machine with Arduino | Version 2](https://i.ytimg.com/vi/r7ZmXTTQmEo/mqdefault.jpg)


![Cherry Mx / Gateron Breakout PCB. Easily Add Cherry Switches to Anything
Cherry switches are almost the best tactile button you could ask for. Mounting them isnt quite as easy as a standard round panel-mount button. This PCB breaks out four keyboard (Cherry/Gateron) switches [buttons] with common ground into a standard 5-pin JST connector similar to arcade joysticks.

![Automated Small Parts Counting Machine with Arduino
A machine that counts and sorts set quantities of parts into individual cups- to replace a human [me] doing this repetitive task. Machine is automated. Once turned on it will count the predetermined set of small nuts (#4-40, #6-32, and #8-32) until completion. This machine is very early in design and inherently also very time consuming to develop. Just sharing my ideas to help other DIY-ers that may have the same redundant task of counting parts.
Weighing parts (the crimp connectors) is always an option, but I am trying to automate the task as an end goal, so counting seemed like the correct first step. Its a learning process.
