We had a great time at the World Maker Faire! NYC was so much fun. We met a lot of great people and great makers. One thing that we ran into is that there are a lot of people who want the machine, but aren't able to back KickStarters. We've been reached...
Well, the NCP1402 has been discontinued by On Semi. That's kind of a huge bummer, as it worked really well, and the design of the Crazy Clock had reached a more or less steady state.Unfortunately, it's sort of hard to pick boost converters for this application....
Now that the loggers have reached the point where they deliver reliable underwater operation, I am realizing that was only half the battle:Field Report 2015-12-10: Precision vs Accuracy vs DriftSo I was wondering if anyone here has already tried oversampling...
Thanks to extensive simulations with GHDL, the VHDL source code synthesised "out of the box" and effortlessly reached 110MHz on the venerable ProASIC3 FPGA family. One SRAM block and about 450 tiles (LUT3) are used.The SmartFusion2 has a different structure...
Sometimes, I get burned out by the hardware aspect of the project. When this happens, I often wonder to myself, "Man, if only I had the Kestrel *finished*, then I can work on the software." I reached that point not too long ago.So, I worked...
Due to popular demand, we've decided to run a Kickstarter for the Mechaduino! We will be launching the campaign next week. Stay tuned for the announcement! We have reached a point where we're really happy with the hardware, and we think it's time to...
In progress now. So far, it is going rather similarly to a previous one, even though that previous one was done on defunct circuit.The threshold voltage is now rising again......UPDATE: finished.Unprocessed data available in files: TORTURE2.TXT. Note:...
Here it is August 28, 2018 and I have decided that IO has reached its limit. I have learned a lot from this project but IO has has grown to the extent that I no longer have enough room to work on any other projects and I might be moving away from the...
A new addition to the range - the QWIIC Edition. This has two Sparkfun QWIIC connectors in place of the 0.1" header and Grove.. Currently in OshPark purple, and 3 available. Red boards are in the mail. I have reached out to Sparkfun to see if I can sell...
Another day...I added a plotting function on my Controller so I can see the follow the output while flying. By doing that I found out the ultrasonic sensor detects distances between 0-25cm over a concrete floor. A little worse on grass. After that the...
Can you believe that the source code synthesised and place/routed on first try and reached an estimated 49MHz performance on A3P060 ?The core occupies about 570 versatiles (3-input cells) which leaves 2/3 of the FPGA (1K LUT3) for GPIO and peripherals...
After watching a recent video on compressors I found that there is a one way valve on my one between the compressor and the tank, this reduces the chance that pressure will appear in the head of the compressor. In commercial compressors the feed line...
It's been a while since I started developing this project and after lots of hardworking, I've reached the 80% of what I planned for the first release. This release will take place during the 34C3 in Germany (hope everything works for then). It will be...
Since the project was first started, it's taken one whole year to get to this stage: satellite navigation through a series of waypoints, accurate enough to stick to a conventional farm track (plus or minus 25mm).I never thought we would get to this stage...
The last week was like early summer in Germany. Temperatures reached 30°C in some parts (86 degree freedom):Log-Data for last week:In these warmer days they have more "trouble" keeping a constant temperature but they try their best. When the outside...
