This week was rather slow, as the two projects I’ve been working on, the electronics for JONA ROV and the cameras for JONA ROV, need parts that I have to wait to arrive.

“Image of the ESC Board V2”

The parts I needed for the electronics for JONA ROV arrived Wednesday, so I spent a majority of that day working on the ESC Board v2. The 3-pin XT30 connectors arrived and I needed to test the footprints I’d downloaded. It was a good thing that I did, as they were not correct and I needed to edit them to fit the parts. The 3-pin XT30 connectors were the last parts I needed to test, so with that done we ordered the board. They should arrive sometime next week.

Mr. Christy wanted me to write a guide for our OMAX 2626 PRECISION JETMACHINING CENTER, so far, I’ve written a text guide, but I will add pictures.

If the material you intend to cut is NOT already loaded and secured into the machine:
Open the program "OMAX Make Premium"
Click "OK"
If the cutting head us lowered so that when you jog it, it might crash:
Loosen the cutting head if it is not already loosened (CCW on handle on side of cutting head)
Raise the cutting head until it is a safe distance up (enough to make sure the cutting head won't crash)
Jog the cutting head away from the material (enough so you can take it out and put in the new sheet)
Secure your material in the cutting bed with at least 2 inches of space in-between where you want your part to be cut and the walls of the cutting bed (Use clamps and weights, make sure there is enough room so the cutting head won't crash)
Close the program "OMAX Make Premium"
If the material you intend to cut IS already in the bed:
Make sure your material is fully secured (It shouldn't be able to move)
If your material is not secured properly:
Secure your material in the cutting bed with at least 2 inches of space in-between where you want your part to be cut and the walls of the cutting bed (Use clamps and weights, make sure there is enough room so the cutting head won't crash)

“Image of my Christmas gift”

Because I didn’t have much to work on this week, I started work on a Christmas gift for one of my family members. I cut and bent this piece of 1/8″ aluminum, and I intend to spray-paint it black and then laser-engrave a design on it.
