I don't think I've mentioned this yet; I'm making two hovercrafts.As it turns out, this hovercraft qualifies as both small AND unusual. I cleared it with Sparkfun peeps, and they said that as long as I have completely individual robots, the same design...
Bootloader programmed using the SEGGER J-FLASH with the BIN file from Sparkfun SAMD21 Dev board bootloader. I will have to create my own custom one in the future. This will require using ATMEL studio which I do not like to use.After bootloader is programmed...
Up until now, I've only been talking about the Hovercraft as an entry for the Sparkfun AVC, but not necessarily going into too many details about that. This update is mainly to clear up a few things.First off, when I decided to turn this into an AVC...
After fixing the last blitter bug, I sat down and combined the four board designs of the V2 prototype into a surprisingly compact two-board stack. Combined PCB footprint is 7"x6" and hardly an inch and a half high.I wondered at first if I'd have to go...
Discussion of ‘hardware’ in this context refers to the electro mechanical components required to build Seek_r. It does not (directly) refer to the hardware requirements in terms of clock speeds, RAM space and other electronics. That comes later.The mechanical...
Going for IP67 Something I learned through the path of enclosure design after our last mentor session with Eric Weinhoffer, is the nitty gritty of enclosure sealing. So our target customer needs a water resistant motor drive, and to be on the safe side...
In my previous log entry, I had fried my CM4 by shorting 5V to 3.3V, so I had to order a replacement, which arrived last week. The next thing for me to test is whether I can boot the CM4 on my board, so I installed Raspberry Pi OS and set enable_uart=1...

Ah, home at last. After spending so long in the mechanical world, I almost felt disconnected from my electrical roots (ba-dum-tss). Corny jokes aside, it has been really nice to get to dig through datasheets, lay down some traces, tear through app notes,...
Read The F-ing Manual Made with beer and late nights in California.TLDR: This year's badge provides bling, an embedded CTF text-based adventure, and a port of MyBASIC extended to the hardware to make it hackable.AND!XOR (@andnxor) * @zappbrandnxor *...
Well, if this project wasn't in "hack territory" before – despite an actual hacksaw already having been part of the process ;) – it's definitely there now!Yesterday, I removed all 32 "anti-ghosting" diodes, and reinstalled them the other way round (except...
The new r5B12 PCBs arrived from ITEAD few days ago and I managed to assemble them to test if new added features are working as expected. All boards are now a little bit larger and I tried to keep the same mounting holes spacing as in previous builds.AUX...
