Chroma ATE has been quietly making really good power supplies for a long time. Today I’m going to talk about 62006P-100-25 which is a 100V 25A power supply with a built in arbitrary function generator. I’ve been using one now for about a year and it’s definitely the best value for the dollar out there now if you need a high end power supply.

Altium Designer Backwards Annotation Hell
I’m tired of searching for reference designators on circuit boards, so I decided to start annotating schematics from the PCB locations. That way all of the designators in sequence are nearby (at least in theory). For example, R1 would be near R2 and R3. The process of reannotating the reference designators on the circuit board and importing the changes back into the schematic is called backwards annotation.
Scuba2 Telescope
Here are pictures of some the cards I worked on for the Scuba2 telescope. These cards were part of the electronics package used to measure the telescope sensor array. Both of them are based around the now ancient Altera Stratix FPGAs. The card below was the controller for the whole package. This card has 2 FPGA configuration memories to make sure it could still boot if a remote update failed.
