Hi,
Just wanted to share some non-robotic stuff I did today.
I have an old Dewalt DW981 XRP battery drill. But the batteries has seen better days.
So I did a little hack by using a 3S 5000 mAh hardcase LiPo battery instead of the old 2Ah NiCd batt. Inside the old case I have a 30 amp fuse and a LiPo warner.
Finally I have a drill with some power again!
