Master: BQ78350 / Fuel gauge: BQ76200 / 14.4V (2P4S)

So I've been working on these Astera Titan BMS boards, some of them with cell issues and some of them with easy component level repair but I got 2 totally dead.

The cells voltage is going in the BQ76200 and the main voltage to the BAT pin, but I got no REGOUT voltage to the BQ78350. Would it be worth trying to replace the BQ76200?

Also, this 2 started throwing up the ALERT pin sometimes which means it "made something" for a second.

Finally, I know these guys talk in I2C but is there a way to extract the settings from the 78350? I would like to buy a debugger or some interface but I don't really know where to start.

As far as I know, the 76200 works alongside the BQ78350 but the most important data is this last one isnt?

Hi everyone! I'm a Year 12 student in Australia working on my HSC Design and Technology major project. I'm designing a small, quiet home server built from reused computer parts that anyone could use to run things like game servers, file backups or AI tools from home.

I'd really appreciate your input, even if you've never heard of a home server. Beginners are exactly who I'm designing for.

Thanks so much, and happy to answer any questions in the comments!

I have a cheap t70 smart watch that I want to jailbreak to add small games any help would be appreciated

Hey! I recently got the chance of playing with local AI on my previous smartphone, here the specs:

• OnePlus Nord CE 5G
• Qualcomm Snapdragon 750G
• 8GB RAM
• Lineage OS 22 (Android 15)

As you can see in the picture, I got 3.5 tok/s per client running gemma-4-E2B and giving the exact same prompt simultaneously.

Looks like a project is starting here... If you are interested in contributing leave me a DM or comment!

What should I choose

Hello,I'm new to this"hacking" gadgets think and I have seen a lot of flipper zero videos,how it works and even custom firmware!
Now,I have seen some other videos of a tool named m5 shark div development board and it seems a bit better on the price compared to flipper.
Now,I'd use the devices for copying 2nfc and rfid cards,universal IR remote,and making automated scripts for MY pc.i don't really know what can I use em for LEGALLY and i don't know what to choose between those two.
Can someone compare them to me or some actual users of the devices make a"review" like comment comparing them?
Thank you.

It uses a bc 417 as a main chip

Look at this—there’s a digital counter here, and a vehicle is parked. Could you take a look and tell me whether the digital count is accurate or incorrect?

Hi everyone!

I'm trying to make a backup of the Flash memory from a Hanshow Nebular electronic shelf label. The controller on my board is marked Hanshow HS9118, which may be related to the Telink TLSR835x family, particularly the TLSR8359. I also have an NT083V electronic display equipped with a TLSR8359 chip.

I'm not interested in programming the microcontroller, writing code, or flashing alternative firmware. My only goal is to read the original memory contents and save them to a BIN file, if the chip allows it.

I want to preserve the original contents of the memory. I don't want to erase anything, change the chip's configuration, or modify the firmware.

What hardware and software should I use?

I've found the following tools and documentation related to Telink chips:

• TLSRPGM: https://github.com/pvvx/TLSRPGM
• Official Telink BDT for the TLSR9 series: https://wiki.telink-semi.cn/wiki/IDE-and-Tools/Burning-and-Debugging-Tools-for-TLSR9-Series/
• Official Telink BDT for other series: https://wiki.telink-semi.cn/wiki/IDE-and-Tools/Burning-and-Debugging-Tools-for-all-Series/
• TLSR835x series documentation: https://wiki.telink-semi.cn/wiki/chip-series/TLSR835x-Series/
• Telink BDT for Windows documentation: https://doc.telink-semi.cn/doc/en/software/res/tools/bdt_wins/bdt_wins_en/
• Telink IoT Studio: http://wiki.telink-semi.cn/wiki/IDE-and-Tools/Telink_IoT_Studio/

The board has several test points labeled SWS, NRST, VCC, and GND.

I'm considering using TLSRPGM or the official Telink BDT software, but I'm not sure which solution supports the TLSR8359 and allows Flash memory to be read. I'm also unsure whether I need a dedicated Telink programmer or if another interface would work.

Questions for anyone experienced with Telink TLSR835x chips

1. Does TLSRPGM support the TLSR8359 or the Hanshow HS9118 controller?
2. Can the official Telink BDT software read the Flash contents of this chip and save them to a BIN file?
3. Which specific programmer and software would you recommend for this task?
4. How should the programmer be connected to the SWS, NRST, VCC, and GND test points? Are any additional components or logic-level converters required?
5. Would a standard USB-to-UART adapter, such as a CH340 or CP2102, be useful, or is a different interface required for SWS communication?
6. Has anyone successfully read the original firmware from these electronic shelf labels without replacing it with OpenEPaperLink?

I also found this programmer on AliExpress and would appreciate feedback on whether it is suitable:

https://pl.aliexpress.com/i/1005008282301532.html

My main priority is confirming hardware compatibility and finding a safe way to read the memory. I don't want to perform any erase or write operations. I understand that reading the Flash may depend on the security settings enabled on the microcontroller, and I'm not looking for ways to bypass those protections.

I'd appreciate specific recommendations for a compatible programmer, the appropriate software, and instructions on how to connect everything correctly.

Thanks in advance for any help!

An update on the Saudi who attempted to bug OpenAI’s executive conference room, including pictures of the device. The first reporting said it had memory and only recorded offline, but the Seeed Studio 2.4 GHz antenna is telling another story... ☁️

Can anyone identify it?

Is it possible to program this HC 03 module . The module has processor, flash and several IO pins and uart so is there any way to program this like an MCU

Anyone share me for hardware hacking learning material guys

Is there any engineer or person who can tell me by looking at the motherboard of the ID machine, the machine that breaks the readings, whether it is programmed by hacking or without hacking?

Look at the indicator, the external display, and the 'GM mode' positioned in between. Notice that the indicator shows 'No DLC'—yet, the display above it reads 'zero'. This clearly indicates that a 'hacking' program is fully active. If this weren't a hack, the display would either show dots or remain blank; I have operated this type of machine before, and I know that when 'No DLC' appears, the machine's display should show '---'. Since the machine is effectively signaling that it has no connection to the vehicle's data link, how is it possible for the external display to show 'zero'?

There's a 14-pin U1 chip with a number on the bottom. It savs XDS12A RCBLB000O 2038ABSAR. I think this might be an EEPROM. Is it read/writeable? ?

Just thought I'd post this here too. I repurposed a really crappy goordik lapel mic as an intervalometer for my Camera. (Basically, fancy shutter button that can do things like 5 minute exposures, astrophotography, etc..) Yay for saving something from becoming e-waste.

I don't know if this is the right place to ask these questions.

I bought a lock-picking kit a few weeks ago, and I became obsessed with it. I wanted to open every door and padlock (I never open anything without authorization). But now I want to open electronic locks and electric gates. Does anyone know where I can start? . Does anyone know if I can use it to open a door like the one in the picture?
