  • I agree with Kamiquasi that it’s not just the box that is the problem. The box, the front/back panels (if applicable) the stand-offs, the components and the PCB size form a system. Nobody has tackled solving the system problem for hobbyists. Well, I took a swing at it (see https://forum.sparkfun.com/viewtopic.php?f=5&t=39492). Standard (free Eagle) PCB sizes, automated front panel alignment, controls and displays that fit, and an enclosure design that’s “open source”, able to be 3D printed. I’m finishing my second and starting my third project based on the system. Take a look. Sorry Dia, it’s still mostly rectangular, but it looks half-way decent and it works. Now if somebody would just mass produce the plastics so they’ll be cheaper. Hint, hint.

  • I wanted a case for my FG085 that would protect it and allow it to sit on my workbench. The one that is mentioned in an earlier comment is marked as not working with the latest FG085 on the Thingiverse site. You can see what I came up with in my forum posting here: https://forum.sparkfun.com/viewtopic.php?f=14&t=40337

  • Here is an I2C controller board. https://forum.sparkfun.com/viewtopic.php?f=14&t=38056

  • I’ll second that. Lancaster’s books were phenomenal!

  • Excellent write up. When I was a young engineer we had a game going. When we worked at fixing a board (of known good design) we would ask if the problem could have been found by visual inspection. About 99% of the time, looking closely would have found the problem. Of course we DID look closely, sometimes just not close enough. ;-)

    Another tip: For new (unproven) designs it is sometimes useful to add components a little at a time to bring up the board in sections. For instance, bring up the power supply portion of the board before adding the rest of the circuit. This can be complex. You have to know how each section interacts with the others (like the power supply might require a load to regulate), but if used correctly this can vastly simplify debugging a complex new design.

  • Welcome home Robert!

  • Different strokes… ;-) That’s the nice thing about creativity. We can each take a different approach and even if the results are similar they are uniquely our own. I look forward to seeing the photos you take on the trip.

  • Very nice job on the Leiger. It is a great example of pulling together existing component modules into a unique new application. I look forward to the tear-down to see how you got that professional looking case/front panel. Looks like it will be an awesome trip. Are you sure you don’t want to take a longer lens? The max in the picture is 100mm. I would at least want my 70-200 for such a trip. Have a great time and get home safe.

  • From a quick look at the schematic, it appears that the XBee socket (WiFly) is on the second serial port not the USB port. I recall reading that there is support for the second serial port by calling Serial1.begin and Serial1.print (note the subtle numeral 1 at the end of “Serial”). I might not be remembering this right, that is, I might have the ports reversed. Double check the documents before changing your sketch. If it’s not in the documents for this product, take a look at the docs for the Pro Micro (DEV-11098) they use the same microcontroller. In particular look at the “Getting Started Tutorial”.

  • Here is another source for anemometer/wind vane, albeit expensive at $100.


    This looks like a very well made device. Reading the description, someone should be able to adapt the weather board to read this. I haven’t tried it and make no promises, but it looks interesting.

    They have a rain bucket too, but I haven’t investigated it.

No public wish lists :(
