IoTink: Your portable e-paper dashboard

In our previous apartment, the gadget I was using daily was the VƤsttraPi which is a Raspberry Pi device with a 7″ LCD screen connected to the internet indicating the next public transport departures. Since we moved, the new layout did not make it easy to have the screen mounted and continuously powered. Since the need to know when buses and trams leave remained, so it was time to use the E-paper display I bought last summer, to create… IoTink! (IoT + E-Ink šŸ˜‚)

Develop faster with Code Review Lamp

At work, we are a fast-paced team that likes to commit small and often. Every commit does not only have to pass the various tests run by our Continuous Integration machinery, but also gets extensively code reviewed before allowed to be merged. Since we are six and our internal code of conduct dictates two positive approvals for each new submission, the lack of responsiveness when it comes to reviewing, can impede the development process and speed.

Custom Actions for Google Assistant

A Google Home MiniĀ  recently made it into the collection of gadgets I use on a daily basis for casting music, setting count down timers, reminders, recipes etc. However the capabilities the software behind it, Google Assistant, expand way beyond that. We saw how it, one day soon, could be making calls and booking appointments for you during theĀ Google IO 18 keynote. Additionally, it is expected to be the catalyst for driver experience, as brilliantly demonstrated by Volvo Cars in the promotional video of their next generation infotainment system. It runs native Android just like your smartphone! There is so much potential in this technology I had to try it out myself.

Crowdfunding open source products

When developing something that solves a big, small or silly problem I ask myself, usually as a mental exercise: How can I make money out of this? Sometimes, this thought experiment is concluded by a crowdfunding campaign where my cool gadget receives support by like-minded enthusiasts who pitch in and help bring it to mass production. Additionally, as an open source proponent I enjoy publishing my work, however this is ultimately a business move. Unfortunately, the lack of insights on the matter deems such decisions difficult and, as the devil is in the detail, surrounds the initiative’s feasibility with uncertainty.

Debug your code with Dialectic Ball

Always fascinated by portable, low power devices and new ways to interact with them, I was very happy to discover these LCD displays that used to be on old Nokia phones and their consumption is in the micro-Amperes range. As it often happens, I had a solution and was looking for a problem. And that is how Dialectic Ball was conceived!

PCB trophies for your Hackathon

During the past couple of years I have been involved in a couple of Hackathons, mainly as a member of the jury as well as the overall organization. One of the most fun tasks was creating the trophies for the winning team.

Moltoduino: Extra cores & HIL testing

If you are like me and enjoy working on microcontroller projects it is more than likely that, at some point, you wished you had additional processing power, extra pins, parallel threads and so on. One way to tackle this is to get stronger hardware and another to optimize your code. A third is to… stack another microcontroller on top and thus Moltoduino was born!

Nevma: Gesture control for the masses

Working at Delphi (soon Aptiv) allows me the luxury of being immersed in a high-tech and innovative environment that provides constant inspiration for creating new and exciting gadgets. One day, some colleagues mentionedĀ gesture controlĀ being one of the recent trends in automotive. This got me thinking of ways to bring gesture control to the broader audience in an affordable and easy to use package. And thus, Nevma was born.

Cryptopuck: Encrypt on the fly

After finishing a project, I torment myself on what to make next. While riding the bus home one day, an idea struck. How cool would it be if there was a small handheld gadget, able to encrypt USB sticks and SD cards just by plugging them into it. And thus the Cryptopuck was born!

SonicDisc: A 360Ā° ultrasonic scanner

For some years now, I have been on a never-ending quest to discover the cheapest way for a miniature vehicle to position itself. One that performs decently that is. My latest idea involved the, less-than-a-dollar, HC-SR04 ultrasonic sensors to acquire a holistic view of the surroundings. But let’s take it from the beginning…
