Hi, I'm Andrew! I'm a software developer from the UK pretending to be a blue fox on the internet!
I'm a massive dork and am interested in amateur radio, electronics, engineering, programming, trains, space, science and a whole lot of other things! In my spare time I am working on a closed-source Space Station 13 codebase at https://nanotrasen.space/!
For my day job I work on the web team for a SME that produces creative software, and there's a non-negligible chance you've used it!
My account is locked purely to act as a bot deterrent, so feel free to drop me a follow request!
...and here is some of the measurements I made from a cheap connector I had laying around. The design on the board is the union of this and the nice Amphenol one.
I still need to uh, actually put a microcontroller on this design so that the host can talk UART to it.
Things I have left to do is to come up with more recommended pin assignments, such as an IRQ pin, and to buy a bunch of common SD card sockets and determine what fuckery I can get away with in terms of part clearances.
For those who haven't seen me talk about this before. This is an idea for hacker badges and the like for a universal addon standard.
The standard supports SD cards as well, using pin 6 on the SD card form factor to identify cards. On SD cards it's tied to ground, but on a Shitty Addon Cardβ’ it's pulled high.
There's a 1-wire EEPROM on the board so that the host can identify what type of card it is. As long as the host knows what kind of card it is, it can configure the pins appropriately.
Cards SHOULD use the SD card pinout if you're using SPI, so hosts can use hardware SPI if possible.
Did some more idea spilling of my Shitty Addon Cardβ’.
Populated the reference board with a DS2431 1-Wire EEPROM for card identification, and put a voltage divider on the detect pin so potential future revisions (different 1-wire EEPROM) can be accounted for in software.
Also removed the solder mask from where the SD card contacts are.
as of yesterday evening, iβm officially unemployed, because for the second consecutive time, my role was made redundant. super great that it happened to be right before christmas! when it seems like the job market is pretty bad!!
i uh, idk. is it at this point that i can mention the tip jar without feeling bad about it? any donation while iβm job hunting helps ;-; https://maff.scot/tipjar
Update on the previous tweet, someone has gotten in contact with me in regards to a job, and they're passing my CV on to the hiring manager. c:
