Today was quite a rainy day, so I was lucky to be invited to the Intel AI Devcamp in Munich. The reason I signed up for this event was to find out, what the current workflow of the AI tools is. Quite some time has passed since I last had […]

During the Electronica 2018 Fair in Munich Infineon was very kind and provided me with a brand new XENSIV Sensors IOT Box. This box is not yet available on the market and will launch probably in Q1/2019. The box features the XMC2GO and XMC1000 bootkit (an Arduino Uno sized ARM […]
My first steps with Infineons XMC2GO
In the last 12 month I supported only a few tiny projects, spending less then 50€ all together on crowd funding platforms like kickstarter. Compared to the years before that’s a huge drop. After many unsuccessful campaigns and products that where not as good as in the pitch videos, I […]

At our home we share a laundry room with our neighbors. In the recent time I have found some evidence that my washing machine has been used by someone else. So I decided to make it a little harder to use my stuff without asking for it. I designed an […]

What is it good for: The IR CAM PI Shield adds infrared LEDs to the Raspberry Pi camera Module. So you can take photos or videos in the dark. Costs: 13$ for PCB manufacturing (for 10 PCBs) -> I have left a few boards, ask if you are interessted. 3$ […]

Introduction A few years ago I received a nice little LED lamp as a bonus in an online order. The lamp had one issue, the circuit was optimized for costs not for lifetime of the LEDs. Initial Ciruit After around of 10 hours of accumulated operation, the LEDs started to […]

I replaced my old Omron pedometer with the Withings Pulse. The OLED display and the design are nice. However it has one design flaw – it’s impossible to attach the little device to your trousers in a secure way. It’s really easy to loose the Withings Pulse with the original […]

2 I won the TinkerForge Weather Station at the Infineon 2013 online Christmas give-away event. It took a little while for the Infineon reindeer to deliver it, but here it is 🙂 Assembling the kit (it consisting of a handful of laser cut Plexiglas, lots of screws and nuts and of […]

1 This app (written in Processing) is our entry for the Intel Perceptual Challenge. It tries to help computer users maintaining a better posture. Sit Perfect detects the users face and determines, if the user sits too near or too far away from the monitor. We use the face detection algorithm […]

What could be better to start a Saturday morning, than a cup of tea boiled with the heat of the sun. — Ok, maybe a cruise in the Caribbean 😉 Last month I picked up this used Solar Cooker for around 60€. It has a diameter of about 70cm and […]

In the last weeks I assembled the Hexy robot together. Soon after building everything together I found out, that the power supply is not capable of powering the robots 19 servo motors. I use five Eneloop rechargeable batteries. And even those quality batteries are not able to fully power the […]

2 Recently we stress tested a Raspberry Pi and checked how hot it got [link]. We were asked to repeat this experiment, with an overclocked RasberryPi. This took a little bit longer then expected but here are the results. The test setup Disclaimer: By no means did we use a nice […]

Just today I also finished this exciting project, a camera rail for the GoPro action camera. It is based on the rails from the german company Igus (link: . I printed two clamps with my 3D printer and added them to the ends of the rail. You can download the […]

14 Its pretty interesting to measure ones heart beat. A lot of fancy analog circuitry is needed for this. But fortunately there is a Arduino shield for this: the SHIELD-EKG-EMG from Olimex. Hardware: – EKG/EMG shield (price: ~24€), Manual: [Link] -SHIELD-EKG-EMG-PA – passive electrode for SHIELD-EKG-EMG shield (price: ~12€) -Olimexino-328 – […]
