I bought an old IBM Thinkpad 240 (from the year 1999). The battery was almost dead, and lastest only 3 seconds. I am planning on replacing the cells, and want to document everything here. FRU: 02K6606 Battery Controller: bq2040 Battery EEPROM: 24C01 The bq**** and 24C01 EEPROM are a commonly seen combination in older IBM

keywords: 3D geometry; triangle selection; vertex selection; When developing 3D software, you might want to allow the user to select specific polygons or vertices from your 3D model. Different parts of the geometry, such as corner points (vertices), triangles or surface normals must be selectable just by clicking on them. The complicated part is not

A while ago I hooked a CAN logger to a friends CRZ, and reverse-engineered it a bit. Hope it helps for your projects 😉 Vehicle CAN Message ID Bit Length Description 0x13F 8 16 ThrottlePosition raw 0x13F 40 32 ThrottlePosition counter 0x164 0 8 Headlight switch 0x164 48 16 Vehicle speed 0x17C 24 16 Engine

The last two days, I had a very interesting problem that I thought is worth sharing. I am developing a project on an STM32 microcontroller. My toolchain uses Eclipse, which uses GDB, which in turn controls OpenOCD, which does all the low-level stuff so that I can flash and debug. That worked very well for

I’ve been using Peters OBDII C&C for quite a while now, and while I like it’s features, it lacks the intuitiveness of a modern smartphone app. So I thought it’s about time to improve this! System Architecture Two MCUs are working together to read the OBDII data from the car, and transmit it vie BLE

During my time at SIMTech, I was working on robotics, 3D reconstruction of workpieces, and path teaching using Augmented Reality (AR). A part of our project was

I wrote this over 10 years ago in high school when I wrote my first 3D game. I still need to copy in the graphics, but I hope it is useful for someone!
