I am in the process of getting the production version of the open-source Raspberry Pi CM4 compatible module based on an iMX 8M plus up and running. If you are interested in this module, check out the Crowdsupply pre-launch page 😊

- I'm designing a modular and easily repairable open-source Linux smartwatch. This system is based on the open-source SiP I've designed and will be able to run custom firmware in a Linux and Android environment
- A wireless SD card running Linux. The open-source SiP fits nicely into an SD card footprint, with enough space left for a WiFi chip
- I'm developing an SDR module for a customer in the C-UAS sector. The system will fit into the Framework 16 GPU module formfactor resulting in a nice fully enclosed solution with lots of processing power and a very high bandwidth link between the radio and the host system. The
- I've set up a simulation of a Rotman lens to drive a phased array in Elmer. The matching of the ports is poor, causing lots of internal reflections, resulting in unwanted side lobes and poor channel separation. Nonetheless I think it still demonstrates the principle nicely 😊
00:00 - Since the open-source smartwatch is modular it's relatively easy to design alternative display or sensor panel modules. I've designed an e-ink display module that I'll be prototyping soon.
- A open-source SmartWatch needs an open-source SiP 🙌This is a tiny linux SBC with 2GB RAM and 16GB storage
- The button on the open-source smartwatch hides a secret 👀 While it works as a standard button it can also be pulled out completely giving access to an IP68 USB-C interface
- Testing another rendering pipeline in Blender. The simulation shows an airflow for forced convection over a circuit board
00:00 - the simulation shows the separate resonant modes of the dual band niche antenna on the CM4 module
00:00 - I´ve assembled the SiP PCBs. One step closer to the open-source SmartWatch 🙌
- I'm currently working on the mainboard for the open-source smartwatch. The SiP takes up most of the space, but also integrates most of the functionality. Only the radio and a few miscellaneous components are placed on the carrier board.
- The Framework Laptop SDR module that I´m designing consists of three modular blocks, each of which can be swapped and upgraded individually. The PA and the AFE each have their own shielding can. The mainboard sits on top of these two cans
- I received some more prototypes for the open-source smartwatch, including a few machined enclosures
