It has been a while since I wrote about ARM development. I recently made a Black Magic Probe (BMP) clone which acts different then the original. The BMP can source power to the target, but on my version control signal is inverted. Not a big deal, but can give...read more
Designing a PCB businesscard seems to be the go-to for a hobbyist electronic engineers. Most people design either a passive PCB, USB HID/MSD device or battery powered LED frenzy. Uptill now I haven't seen any cart that has a RFID, not even regular paper ones. As usual...read more
I played some time with the idea of making a cheap testing/programming jig. For the T12 controller I had one professionally made in Shenzhen. It wasn't too expensive but IIRC it was about 65-75 USD and came without any wiring. Testing jigs are basically a fixture for...read more
As a good electronic hobbiest tradition I started to design a businesscard from PCB material. Downside of all the businesscards (and PCBs in general) is the limited number of colors you can use: FR4, soldermask (with or without copper behind it), silkscreen or bare...read more
When I was in China last year I sourced a couple of small E-ink displays (GDEH0124S01) through Taobao. They were simple ones with 8 14 segment characters. After some searching on the Chinese website from the manufacturer I found the datasheet. It was by all means not...read more
Today came in a new batch of PCBs from DirtyPCB.com, of which one is a new revision of the BlackMagicProbe. This revision is almost the same except it has a polyfuse in its powersupply to the target, a dedicated voltage regulator instead of P-FET, its programming...read more
