ATTAMI
[2023] We are back!
after loosing our old wiki to some digital storm
git for pcb https://github.com/telavivmakers/at-tami
TODO
- research uploading fresh firmware via user soundcard.
- see example at 8Bit_JogjaNoise
- tinyAudioBoot (SOUNDRX)
- audioino HTML-Mirror
- simple attachment to flipperZero (new board?)
LOG
update #5
we had a Suprise Devboard meetup on Monday.
found some inconsistencies with assembly of prior boards (flipped components) sorted and more boards are getting done.
Flipper zero jig
the reflow station moved to a stable home.
start talking about v2 of the 1$ ATtami devboard (ATtiny85 price has rocketed)
a few interesting Canidates for a 1$/5₪ board.
- CH32V003 aka RVTAMI
- STM32g030f - aka ATtami32
- PIC16F17114 - aka cuTami(?)
update #4
we (Aleksander) started the hot-air scavenging process
got all the attiny from previous iffy batches
ready for reprogramming of the bootloader.
astra used the flipper zero to dump the EEPROM/Flash and made a duplicator jiggy
no board left behind, come get your buttons
update #3
was great, we got the pcb oven reflow profile dialed in, first boards came out nicely!
Tonight we'll scavenge more Attiny85s from old defunct boards and get the process going on our new nixos based dev station!
update #2
After Thursday where nothing worked (macmini must die) or got burnt.
This time we will actually test our reflow oven on actual boards. Not just (yummy) sandwiches
update #1
om-num..
come Wednesday, we will continue working on the ATtami, last time we
- adapted an old (non-food) toaster from tami pile-o-junk and retrofitted it for our temperature probing
- learned about different reflow profiles , figured out why last time we did the workshop the boards mostly came out undercooked.
- got a truck load of very good meet sandwiches form the night watchman to test on (crunchy/toasty!)
- dug for the right one to fit our Sn63Pb37 soldering paste (hopefully)
- patched our oven controller code to fit.
