You know a piece of tech is going to be fun to take apart when it makes you go buy a new set of bits just to be able to open it

Foone🏳️⚧️ (foone@digipres.club)'s status on Monday, 30-Sep-2024 14:35:06 JST Foone🏳️⚧️ @skaverat now that it's been leaked on mastodon, do I have to change my safeword immediately for security?

Foone🏳️⚧️ (foone@digipres.club)'s status on Tuesday, 01-Oct-2024 08:11:51 JST Foone🏳️⚧️ I know some Apple products use tiny pentalobes but this is a ~4mm screw. way bigger.

Foone🏳️⚧️ (foone@digipres.club)'s status on Tuesday, 01-Oct-2024 08:18:45 JST Foone🏳️⚧️ a set of Torx Security 5-point Star bits are on the way

goonergirl420 (puppygirlhornypost@kitsunes.gay)'s status on Tuesday, 01-Oct-2024 08:20:00 JST goonergirl420 @foone@digipres.club can I see your bits?
-
goonergirl420 (puppygirlhornypost@kitsunes.gay)'s status on Tuesday, 01-Oct-2024 08:20:02 JST goonergirl420 @foone@digipres.club nice pentalobes foone, wasn’t expecting to see you here on my after dark account timeline but here we are.

Foone🏳️⚧️ (foone@digipres.club)'s status on Tuesday, 01-Oct-2024 08:36:51 JST Foone🏳️⚧️ @dragonarchitect I suspect the company that made this device was trying to keep people from opening it.
naturally I'm not gonna let that stop me

marado (marado@ciberlandia.pt)'s status on Tuesday, 01-Oct-2024 08:41:44 JST marado @foone including one for screws that big? What are they numbering it?
-
Foone🏳️⚧️ (foone@digipres.club)'s status on Wednesday, 02-Oct-2024 05:12:11 JST Foone🏳️⚧️ I'M IN.
More pictures later, I gotta go take someone to the doctor, but for now... Why design your product to be waterproof when you can just glue some silica packets in there?
-
Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 03-Oct-2024 07:25:43 JST Foone🏳️⚧️ OKAY so this is a Lyft BIT041B, e-bike location and communications module.
-
Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 03-Oct-2024 07:27:13 JST Foone🏳️⚧️ After I bought the right screw bits, I'm in. Obviously this thing is going to be heavy on communications, so we've got a bunch of comms chips.
-
Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 03-Oct-2024 07:28:24 JST Foone🏳️⚧️ Opening it like a book reveals the battery, a bunch of wires, a GPS module, and the other side of the PCB. It's got another big chip and a SIM card holder.
-
Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 03-Oct-2024 07:29:39 JST Foone🏳️⚧️ That GPS module is a VCU GNSS Rev A, by Lyft. I'm really surprised they made their own module for this, you can get something just like this off-the-shelf. This was hotglued in, btw.
-
Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 03-Oct-2024 07:32:20 JST Foone🏳️⚧️ That chip is a Quectel LC79D: Dual-band, multi-constellation GNSS module.
It's got support for GPS (USA), Galileo (EU), GLOSNASS (Russia), BeiDou (China), IRNSS (India), and QZSS (Japan). -
Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 03-Oct-2024 07:35:58 JST Foone🏳️⚧️ The big chip on the main board is another Quectel chip, an EG21-G. That's an LTE module, with support for LTE/UTMS/HSPA+/GSM/GPRS/EDGE.
It has another integrated GNSS chip.
wait what? This thing has two GPS modules!? -
Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 03-Oct-2024 07:37:14 JST Foone🏳️⚧️ our other Clearly RF Chip is this Espressif ESP32-s2-mini-1.
This does Wifi (b/g/n). -
Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 03-Oct-2024 07:39:33 JST Foone🏳️⚧️ And we've got a winbond W25Q256JV. That's a 32 megabyte SPI chip.
-
Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 03-Oct-2024 07:40:58 JST Foone🏳️⚧️ And on the backside we've got a ST STM32L4S5VI. That's an Arm Cortex-M4 running at 120mhz. This variant has 2 megabytes of onboard flash memory and 640 kilobytes of ram (WHICH SHOULD BE ENOUGH FOR ANYBODY)
-
Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 03-Oct-2024 07:42:07 JST Foone🏳️⚧️ The other PCB is the front panel. It's got an LCD on it (monochrome, I think?) and an antenna for NFC.
-
Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 03-Oct-2024 07:43:18 JST Foone🏳️⚧️ The flip side has a single chip on it: An NXP PN7150L That's an NFC controller (and an ARM Cortex-M0)
-
Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 03-Oct-2024 07:44:41 JST Foone🏳️⚧️ Plugging the battery back in, it powers on, but says it's at 0% battery.
-
Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 03-Oct-2024 07:45:54 JST Foone🏳️⚧️ It then sits on this screen permanently, saying Please Wait and an error code: 0x24007.
This is probably it trying to dial home, but since I pulled the SIM card it can't do that.
-
Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 03-Oct-2024 07:47:00 JST Foone🏳️⚧️ The battery is a 3235mAh 18650 with a 5 wire plug on it.
-
Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 03-Oct-2024 07:48:28 JST Foone🏳️⚧️ I think the display has a backlight, and that thing in the bottom-left looks like an ambient light sensor, but without being able to boot the thing further I can't get it to turn on the backlight.
-
Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 03-Oct-2024 07:49:32 JST Foone🏳️⚧️ This did have a sim card in it when I got it. it's still active.
-
Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 03-Oct-2024 07:50:46 JST Foone🏳️⚧️ And it's got a set of connectors on the back. Presumably whatever scooter this plugged into had some of these, but I don't really know why it needs SO many.
Maybe variants for different types of scooters? At the very least, I think it's hooking into a can bus and power (so it can recharge the battery, since there's no other input)

doskel (doskel@masto.doskel.net)'s status on Thursday, 03-Oct-2024 07:55:32 JST doskel @foone is this one of those funky hybrid lcd/e-paper/"SHARP" displays? or am i just going mad?
-
Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 03-Oct-2024 07:55:32 JST Foone🏳️⚧️ @doskel no, I think it's just a monochrome LCD with a lot of contrast. It doesn't seem to be epaper
-
Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 03-Oct-2024 08:01:04 JST Foone🏳️⚧️ @stilescrisis I recognized it as a GPS/GNSS module, and I've ordered breakout boards for these before. Things like this:
-
stilescrisis (stilescrisis@mastodon.gamedev.place)'s status on Thursday, 03-Oct-2024 08:01:05 JST stilescrisis @foone How do you know what it does/that you can replace it with an off-the-shelf part? I'm confused.
-
Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 03-Oct-2024 08:04:58 JST Foone🏳️⚧️ @stilescrisis not really? it's the same chip, they just put a different connector on it.
-
stilescrisis (stilescrisis@mastodon.gamedev.place)'s status on Thursday, 03-Oct-2024 08:05:00 JST stilescrisis @foone but isn't it possible theirs has better reception or lower battery consumption or something like that?
-
Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 03-Oct-2024 08:07:12 JST Foone🏳️⚧️ Missed a chip! There's an Nordic Semiconductor nRF52840 SoC on the back.
That's a Bluetooth/BLE/NFC/Zigbee chip.
(It's also an ARM Cortex M4. ) -
Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 03-Oct-2024 08:09:51 JST Foone🏳️⚧️ So I searched for "Lyft ebike" and this image came up. Apparently in 2021 they were testing these out, and it looks like the actual released product is basically this thing but inside a plastic enclosure.
So either this is just the internals, or this is a prototype for something they later built.
-
Foone🏳️⚧️ (foone@digipres.club)'s status on Thursday, 03-Oct-2024 08:33:27 JST Foone🏳️⚧️ @vfig @stilescrisis heh.
Actually the module is named "Gravity" and that switch is for selecting which interface to use, i²C or UART
-
vfig (aka leviathan_bound) (vfig@mastodon.gamedev.place)'s status on Thursday, 03-Oct-2024 08:33:28 JST vfig (aka leviathan_bound) @foone @stilescrisis okay forget the lyft thing, now i am wondering why this board has a switch for turning off gravity
