My experiments with the different variants of the Arduino family. It’s partially a notebook for myself so that I don’t have to reinvent the same wheel over and over again. But I hope, it’s also helpful or entertaining for the curious browser.
As always, have fun exploring;-)
Our kids are off to college now but I could not stay away from the Science Olympiad fun. So I plan to play the Event Manager for the “Division C – Electric Vehicle” @ the San Joaquin County Event. That will be my first time to run an event, so it will be quite interesting.… Read More »
This post is way late:-( First I got stuck trying to find or build a Fritzing part for my TSL235R light sensor. I tried to build the part in FreeCAD but that died a couple of times on me, so I got frustrated:-( I constructed other things with FreeCAD and had no problems, but it… Read More »
The third sensor in my collection is the force sensor. The Vernier Dual-Range Force Sensor costs around $109. My version was < $20 in parts in addition to the Arduino. Yes, it’s not as nicely calibrated but you should be able to get it close. What is a force sensor really? A weight scale held… Read More »
Ok, it took a bit longer than expected. But here is my version of the Vernier CBR2. That sensor is basically a ultrasonic distance sensor. All the other data is calculated based on distance changes over time. I’m using the HC-SR04, which is a very cheap ultrasonic distance sensor. Depending on how long you want… Read More »
It’s this time of the year again and preparations for the regional Science Olympiads are speeding up. This year, I looked a bit at the four sensors/probes to be used in the “Technical Problem Solving” event. I’m just a parent, so I don’t have ready access to the official Vernier probes or software. But with… Read More »
Halloween is always a time for me to try different things. So I tried to take some photos and videos of this years displays. Unfortunately, it rained pretty much the whole time, so I had to water-proof the things and did not want to go back in there to fix things:-( But it looked that… Read More »
OK, so we saw and played a bit with the MaKey MaKey at the Bay Area Maker Faire and it’s a fun little piece to play with. I have a fifth-grade teacher in the family, so the plan is to enrich the class room a bit;-) I always want to look a bit behind… Read More »
OK, nobody knew what to expect for our Arduino Day event. But about 20 makers had a good time @ Robot Garden😉 Most knew their way around. But we also had a couple of kids who were new to the idea of `hardware hacking’ and liked the idea of an easy start. So instead… Read More »
We will have our own event @ Robot Garden in Livermore, CA to celebrate the 10th Birthday of Arduino – The little computer that can;-) I brought it up, so naturally, I got to organize the event;-) More information is available at the meetup page for the event. I hope, we will have some interesting… Read More »
Last night Paul Zander, Bob Smith, and I gave a presentation/demo for the Silicon Valley Linux Users Group on little computers ranging from Arduino to Raspberry Pi and friends. I believe the audience had a good time and we had interesting discussions afterwards. My slides are here SBC_SVLUG_mw (PDF)and most of my demos are described… Read More »
