..one opportunity at the time..
sensors and general arduino fun.
Nothing serious, trying to catch up on some loose ends. One of the fun things I tested today was seeing how low my input voltage can go before the output (5 Volt) collapses. The background to this is that initially when building Jeti sensors, I used step-down converters to allow the use of 2S battery … Read more
I finally reached D-Day (Departure-Day) and have been taking it easy the last few weeks. Easy as in not spending time on modelling activities, but more time on ‘Life’ things. But, since a few days, Autumn seems to have arrived, so a good time to warm-up the soldering iron to keep the man-cave warm. One … Read more
Finally got the airspeed sensors, so what better to do on a rainy afternoon them to play with them? First the specs: Datasheet, and a picture. Bear in mind that all these diy chips are basically old stuff. This one dates from 2012. Obviously nothing wrong with them, they are still used in a lot … Read more
This series has an extra voltage regulator, I have a feeling the version that runs straight on the 5V from the receiver is a bit too sensitive to voltage fluctuations. These ones are to be fed from a 2S Lipo or LiFe supply. Time will tell if I am right ;-
Continuing with the Barometric Pressure Sensor saga. Here are the data sheets for the MS5611, and the MS5607. The parts that show the different methods for calculating pressure and temperature are highlighted in the images. Use the linked datasheets if you can’t read the fine print. Crudely changing the code at least gives me good … Read more
I received some chips last week, they are to be used in a VarioGPS unit for Jeti. I’ve build around a dozen of these things now, and so far I have had no real issues. So what happened? As always with stuff from ‘the east’ you never know what you get. But I am jumping … Read more
I wanted to use this nifty little display for my RPM display of the spindle on the CNC-Router. It somehow switched to a 128*32 mode. Digging in the code, I found a problem (for me, in this sketch) Activating the 128*64 define in Adafruit_SSD1306.h library, fixed it. Yes, of course, it (they) will go into … Read more
