Nice use of the switch panel from the printer! Usually when I harvest printer parts I just throw away these panels, I didn't even _think_ of your SMD resistor trick to adapt it to your needs. I have definitely filed this tip away for future use :-)

Nice work, thanks for sharing. What printer settings did you use? I'm especially interested in what supports (if any) you used and how difficult they were to remove.

It works! I might increase R1 a bit more to bring the brightness down - with a PCB this small you can actually feel the heat. It does seem stable though. I've attached all of your files that I have changed. You'll need to remove the .txt extension, then unzip. Let me know if it doesn't work.

Thanks again, that PCB displays perfectly on Kicad here. Can I ask how you did the export? It's a long time since I've used Eagle, and it certainly wasn't trivial to export to Kicad back then!The schematic doesn't work so well for me. No worries if you don't have time, but you may need the cache.lib file which I think has the schematic symbol information... but I'm happy to do the schematic myself too :-)Does Instructables accept .zip files? That would be a way to package up an entire project folder...
Thank you :-)
Nice work Waltx! The work you put into the PCB makes it possible for people to etch a single sided board at home, which is really useful! I was unimpressed by the commercial offerings too - as you say, they all seem to focus (pun intended!) on brightness at the expense of battery life. Your example should be much more useful for me, and probably many others. Is there any chance you could share a PDF of the PCB layout? Or your Gerber files? Kicad is supposed to be able to open Eagle's .brd files but it fails on this one.Otherwise if anyone else is interested, let me know here and I'll transcribe from Waltx's excellent schematic.Thanks again Waltx!

This is great! How do you decide where on the ski to mount the seat? Is the weight distribution or "balance point" important for a plezuh? After watching some plezuh videos online, I think you might want to put some more padding on the seat :-)

This looks fantastic! There are hundreds of "arduino robot platforms" out there but this one stands out for a few reasons:1. The pen plotter! Just like the Turtle graphics that introduced so many kids to programming in the 1980s...2. Proper source files! Not just a Tinkercad link, but real editable 3d files for Freecad.3. Just like 2 above, but for a Kicad PCB. great stuff.I do have one question though. A few of the links to the Github source files are dead - I assume this is because you are continually evolving and improving the design! Can you please tell me which versions of the PCB and printable files are the most recent/best? For example, I get a 404 if I look for the Freecad files at https://github.com/aspro648/OSTR/blob/master/V2/3DThanks again :-)
Thanks for the fast response! That link looks good. This project has just moved from the back of my "to do list" to the front :-)I think I am getting the hang of the directory structure on Github. Is it correct that some of the "V1" files still need to be printed, UNLESS there is a replacement in the V2 folder?ThanksNick

I think my last comment got eaten by the website. i just wanted to say great job! Much better than just screwing a bunch of AliExpress (or similar) modules together. I enjoyed reading about what _didn't_ work too, especially when all your research said that it _should_ work. This is why it's so important to actually build something!If blue-green algae has a specific absorption spectrum, you might be able to use a spectrophotometer to measure it in the lake. One example is described here: https://www.instructables.com/Science-With-Rainbows-Spectrophotometry/
Excellent description of your project. You did so much more than just buy a bunch of modules on Aliexpress (or similar) and screw them together. I enjoyed reading about the parts of the project where you really thought you had found the optimal approach, but testing showed that it definitely wasn't :-)And yes, autonomous vehicles ARE cool. even with their many flaws :-)There are a few Arduino spectrophotometers here on Instructables - if blue green algae have a predictable absorption spectrum, a spectrophotometer like this might be able to measure their presence... https://www.instructables.com/Science-With-Rainbows-Spectrophotometry/

Wow, that's a real shame. I wonder if it's because Autodesk owns Fusion360 AND Instructables? In which case: Hi Instructables/moderators - can you please explain why .FCStd files can't be shared? Thanks :-)PM sent.
I would suggest you stick with FreeCAD! It's 100% free, open-source, and doesn't require subscription or signing up. Also with FreeCAD you're not required to be online all the time, which is great if your internet connection is unreliable or expensive. The FreeCAD forums are helpful and VERY supportive.Would it be possible for you to share your source ((.FCtd) files here so we can edit/play with them? Thanks :-)
