Research and development continues with cutting (and recutting, and recutting) the new silicone button casting mold. I’ll be verifying the dimensions tonight, but things are moving along nicely. I may be able to get one of the new v4.51 boards close to fully assembled. Which I am very
much looking forward to. The last major task is to engineer a jig to hold a dremel flex shaft that will attach to my cnc machine. This will let me cut a hole for the USB jack with precision and repeatability on the case. After that, I’ll be able to kick into a higher gear for producing units and kits. Whew!

Fail.

a sea of machineable wax chips. This mold would end in disaster.

Present and future casualties of my learning process

Try number 3. This one went well after 5 days of chipping away at it.
