Interesting seeing how different companies solve the same problem. Crazy difference in number of components for such a simple task. I've also noticed they've been using flat flex way more in cheap products, guess it's way more affordable these days.
did something similar for laser rulers, they're mostly clones with stm32g0 / stm32f1s in them. lots without bluetooth has the pad for it. wanted to see about using the optics because you can get those things for like 6$ usd while the module that is in them by itself is 45$+, they can do ranging much faster than the ui suggests
I have a question. You can connect a mouse to a cheap watch and that works to make a bluetooth mouse, I'm trying to make "mouse pen" to draw on my cell phone, I didn't connect it by cable
Sir Please Help me. Afte Repair I want to operate car meter on my table and check with Can Hi and Can Low connections. So please help me. I Have MCP2515 and Arduino uno board. Please share coding details 🙏 I really appreciate your work. You are genius. I will tell my subscribers to join your channel too. (my english not good so ignore my mistakes)
an masculine urge to just open every electronic device you get your hands on XDD
if you can't open it, you don't own it
*Summary*
*Inclinometer 1 & 4 (Similar Design):*
* *(**0:00**)* *Price:* ~€5
* *(**0:00**)* *Features:* Basic inclinometer, displays angle of tilt.
* *(**1:29**)* *Microcontroller:* Custom chip (likely 8051 core) with integrated acceleration sensor.
* *(**6:00**)* *Display:* Segment LCD
* *(**2:31**)* *Notes:* Features a two-wire debug header but with a custom interface. The host plans to extract and analyze the firmware.
*Inclinometer 2:*
* *(**5:58**)* *Price:* ~€5
* *(**5:58**)* *Features:* Basic inclinometer, displays angle of tilt. Error message if not placed correctly.
* *(**7:14**)* *Microcontroller:* CMS79F5139 (likely 8051 core)
* *(**6:52**)* *Display:* Segment LCD driven by YL621 driver.
* *(**7:19**)* *Sensor:* Unknown I2C acceleration sensor.
* *(**11:00**)* *Notes:* Features a debug header (likely CMS debug port).
*Inclinometer 3:*
* *(**8:11**)* *Price:* ~€5
* *(**8:17**)* *Features:* Displays angle of tilt, percentage, and millimeters. Hold button for on/off.
* *(**9:49**)* *Microcontroller:* Unknown, integrated LCD driver.
* *(**9:49**)* *Display:* Segment LCD
* *(**10:02**)* *Sensor:* Unknown acceleration sensor.
* *(**10:42**)* *Notes:* Includes a debug header with UART, potentially outputting useful data.
*Inclinometer 5:*
* *(**11:17**)* *Price:* ~€5
* *(**11:17**)* *Features:* Dual spirit level & digital inclinometer.
* *(**12:23**)* *Microcontroller:* Unknown, similar to the one in Inclinometer 1 & 4.
* *(**12:23**)* *Display:* Segment LCD
* *(**12:48**)* *Sensor:* Unknown I2C acceleration sensor.
* *(**13:13**)* *Notes:* Very similar design to Inclinometer 1 & 4, potentially using the same custom chip.
*Inclinometer 6:*
* *(**13:41**)* *Price:* ~€5
* *(**13:41**)* *Features:* Basic inclinometer, displays angle of tilt. Poor LCD visibility.
* *(**15:53**)* *Microcontroller:* HK32F030MF4P6 (ARM-based)
* *(**16:53**)* *Display:* Segment LCD driven by a separate driver (likely the same as Inclinometer 1, 4 & 5).
* *(**17:19**)* *Sensor:* Likely a 3-axis acceleration sensor.
* *(**16:35**)* *Notes:* Features both SWD and UART debug headers, making it a good candidate for custom firmware development.
*Inclinometer 7 (Wireless):*
* *(**19:01**)* *Price:* ~€14
* *(**19:01**)* *Features:* Bluetooth connectivity for wireless data transfer. USB-C charging.
* *(**22:01**)* *Microcontrollers:*
* *(**22:01**)* Dialog DA14580 (ARM-based) for Bluetooth functionality.
* *(**24:01**)* Same custom chip as Inclinometer 1 & 4 (likely 8051 core) with integrated MT831 acceleration sensor for core functionality.
* *(**24:01**)* *Display:* Segment LCD
* *(**24:50**)* *Notes:* Combines a low-power custom chip with a powerful Bluetooth module, making it the most versatile option. The host finds this combination particularly interesting for tinkering.
i used gemini 1.5 pro
Love your teardown videos, and very nice you have been posting frequently recently 😊😊
very interesting, thanks!
best kind of unboxing video

Klasse, Aaron. "Through the magic of buying two of it...". Well, four? Five? @Technology Connections ;)

an android speed trap has been my forever project, the rulers with bluetooth is everything you need but the camera and stuff on the phone
Thank you for sharing ❤
OK, but does it run Doom?
With haptic feedback?
This. When Aaron said '32KB of Flash, reprogrammable'.
none of them running doom... yet...
Oh it has UART!
Now try to get a shell lol

Sir Please Help me.
Afte Repair I want to operate car meter on my table and check with Can Hi and Can Low connections.
So please help me.
I Have MCP2515 and Arduino uno board.
Please share coding details 🙏

How did you find out what MCU is that die you have extracted from the package?
Hey, i looked on it under the microscope, there was a small field with the name :) thats why the decapping happened in first place
@@atc1441 Nice catch :)
