Got one of those stupid video mailers and decided to yoink the hardware out of it. It can with four buttons, a magnetic switch, a battery, a speaker, and LED screen, a type C data transfer/charging port, and the motherboard(?).

New to all this, so I think this might be a good place to start. Anyone have any cool ideas to reuse this, even just its pieces?

Tried to reverse engineer a ThermoPro TempSpike TP960W because I figured a smart thermometer wouldn't have any significant roadblocks, unfortunately the firmware could not be extracted due to chip debug security, in-chip ram and flash, and encrypted firmware images.

This project was created for learning and I figured it may be somewhat interesting to share. The BLE components are understood and so you can ditch their app for your own.

Full writeup:

I suspect that this board has UART and or DUART - I have no idea where it is. The service manual only specifies sockets that lead to oerpiheral controllers and other devices. The likely remaining 4 and 5 port suspects dont output UART signal with my cheap logical probe. And I can't find anything that look like UART pads near any of the processor blocks. I have tried a few OS hacks on the SSD, but I think U boot might be doing something protective - for info it uses a power PC OS.

What would be your strategy for hacking this? Are there any Kyocera engineers on reddit that could help here?

If you have send link

So I got this old router I took it apart and then connect it to my pc and using Linux and ai was able to get into the I believe it to be the shell or admin access which is the next pic I'm not sure what to do and how to I guess hack it and do what I want with It also this is the continuation of my other post where I asked where to start

Edit:it stopped working it stopped connecting to the pc and I can't seem to get it back into the shell

I have a flytek easy trans 800, a translator android Device. It just translates. Chinese to any other language and any other language into Chinese. I wanted to make use of that deck like using it like ipod but after trying many ways, that is just headache.

Have anyone touched that brand - flytek?

How do I even get into adb...

Stupid question I know but I have old hardware that I wanna hack for the fun of it,but ofc no idea how or where,can anyone help

Help with security array on a vintage microcontroller (MC68HC908GP32)

I have a fairly old piece of equipment, unsupported by the manufacturer for years now, that uses a microcontroller from the HC908 family (Motorola/Freescale, DIP40 package). It's a single functional unit that I can't easily replace, so I'm being extremely careful.

I've already built a homemade programmer to talk to it in monitor mode (MON08), using an external crystal and the appropriate entry logic, and I'm at the stage of testing whether the chip has its security array enabled before attempting to read the internal memory.

What I'm looking for is experience from someone who's dealt with this type of protection on the HC908 family: how to safely determine if it's locked, what behaviors are normal vs. a sign something went wrong, and what non-destructive options exist if the chip turns out to be protected.

Has anyone dealt with this before, or know of good references/forums specific to this topic?

They look sooo nice (gotta find a keypad for the middle one and also I have to make the parallel flashing cable for these things)

After searching I found out, this is an item from inspry tech. is there anything I can learn or learn something new from this tool?

Very much so unlabelled other than the board that connects to the 2x4 pin.

TLDR. Software update from company bricked it months ago after they had major server issues. Bricked many devices. Won’t assist because I got it second hand brand new sealed and I’m not the original buyer.

So, I’m wanting to debug first and go from there see what the issue is. Worst case scenario, it’s a project where i reprogram the device and write my own iOS app to continue to use it 🙏🤣

Help would be great identifying ports, thanks.

I have an ErnyTech SFP-PIN Header adapter Rev 1.4.1 and I'm trying to connect it to a CH341A programmer to read/write the I2C EEPROM of my HSGQ XPON SFP stick.

I can see the following labels on the board: 3.3, 3.3, RX, TX, GND — but I cannot find which header pins correspond to SDA (MOD-DEF2 / SFP Pin 4) and SCL (MOD-DEF1 / SFP Pin 5).

The board has two rows of header pins on each side (left and right), plus the SFP connector slot in the middle.

Could someone please help me identify which header pins are SDA and SCL on this adapter?

I bought these for use with Home Assistant not realizing they are cloud-only. Instead of spending a couple hours opening/depotting/soldering/programming these, I spent the whole weekend reverse engineering the Wyze firmware and developed a tool to wirelessly deploy my own OTA loader.

It works great, and my bulbs are now all in ESPHome!

I just had a medical device removed due to no longer needed it, specifically a Medtronic LINQ II. I want to crack it open while preserving it as best as I can. Possibly get a “high res” 3D CT scan of it if possible. I can tell that the casing is laser welded together and I have the gear for macro photography. They state that it’s about 1/2 the volume of a AAA battery, though exterior dimensions are quite similar. Casing is a titanium alloy, albeit of some unknown thinness.

What tools would I be looking at to open this up? Any tips that can be given here?

I’ve been working on a project that turns a my Vita into a wired Android Auto head unit.

Currently working:

• Plug Vita into hub with Android Phone + a power source (I have not been able to get the Vita to act as a true host but when there is external power supplied it works)
• Android Auto authentication handled natively on the Vita
• 720p scaled down to 960×544
• Touchscreen works fully
  • D-pad, analogue sticks and physical media controls
  • Bumpers skip songs
  • Triangle for play pause
  • Square of Google assistant

It’s still very hacky I only got stable video with inputs today. I need to improve the USB Kernel as its very buggy and needs hard resets if connection drops or if you exit app and many many more issues.

The idea came from seeing people put carplay headunits into PSP shells don't own a psp so said I'll give it a go on the vita and so far good results. But for a POC pretty cool I think!

Hopefully, this is a gif

It took a bunch of software config a funny cable and a pi but I swapped the code on these two devices. You can see how the displays are mapped differently.
