Hi mach1

Once retired, you will soon enter a very busy time, trust me on this one   ;)

I don't own a CNC machine anymore
This project is a nice opportunity for you get into the 3d printing Universe
Files are on Thingiverse

A good printer can now be had for less than $200


My advice: get familiar with servo motors first and spend time on the test bench before building the final prototype

Hi Kas

I am slowly assembling what is needed for this project. What do you think about this as a power supply:

https://www.ebay.co.uk/itm/Waterproof-18650-Battery-Pack-8-4V-Case-House-Cover-for-Bike-Light-Lamp-UK-stock/282920287390?hash=item41df5cfc9e%3Am%3Am5OE9_yJ4FOGiJXL5Qt36zw&var=582770477611&_pgn=2&_sacat=7294&_nkw=bike+light+battery+pack&_from=R40&rt=nc

8.4 V to power the Arduino, 5 V to power the servos.


By the way I am heading for the Android route. Any chance that I can have the app now in readiness?

Thanks.

Hi Mach1
This device with 6 X 18650 batteries will be OK, but is pretty much overkill for the job
Same with two batteries only will be 100% acceptable

I power my own bot with 2 X LiFePO4 batteries
6.6V is slightly out of spec for both Arduino and servo's, but it works pretty well
