Just a reminder~

If you follow me on this account, I've moved over to @lethalbit at gensoukyou.jp.net So if you want follow me over there~

Hey, if you tried to follow my new account in the last hour or two the request is stuck, you should try that again, It'll work this time.

Hey all, I've moved on over to @lethalbit, you can find me over there.

Working on importing the following, but misskey is kinda futsy with that.

I... I wonder if I could make a really janky-ass BGA ZIF socket with some laser cut acrylic and pogo pins.

So that's the flash, 256MB CMOS NAND EEPROM.

there look to be a few test points around it, but it looks like you need full access to it's parallel IO/Address bus to actually pull the data off it.

Womp Womp.

Looks like I could just run code on the thing if I had a JavaCard and knew what it wanted. Fun.

I'm sorry, I'm not familiar with serial to b̸̝̏͂̒͗͑̇̚͝ͅt̵̟̦̬̪̲̯̳̑̀̓̐̚͘̚ẻ̶͓͚͈͉̑̎̄͜s̶͖͋͋̏̆͐

Looks like it's got an anti-tamper switch in it. That's gonna be fun.

Looks like it's got a few ASICs, or at least rebadged chips in it.

That's kinda a pain.

A good place to start is to look at the FCC documents for things you want to poke.

Lots of good stuff.

Christmas came early it seems~

Yet more firmware to dump~

Aaay there we go, that looks nice.

Still so much empty space on the PCB, Ideal spot for a logo.

I am distraught to find that the 8-position SmartCard contact footprint I made, that I thought I updated to make better, was in-fact, not updated. RIP, well I guess I'm fixing it again.

I'm still trying to find a project excuse to use SMA connectors.

I don't have one, but I'm trying.

@aidalgol yup, the hardware schematics and board files are all open source, the firmware is open source, the gateware is open source. All of it.

@aidalgol It's a SmartCard R&D / Audit tool I'm working on.

The idea is that it can emulate both a card and a reader, clone cards, act as a MiTM between a card and a reader, etc. All kinds of fun stuff.

Eventually I want to add a daughterboard to allow it to speak RFID/HID and NFC, maybe make a SIM and MicroSIM adapter too.

I still need to figure out a nice logo for lethalcard. It's a shame I can't do graphic design, RIP.

Here I am worrying that a trace is too long, zoomed in like 500% only to realize that it's only like, 1cm.
