  • Couldn’t wait. “Shield” proto board design: https://forum.sparkfun.com/viewtopic.php?f=42&t=41147

  • ESP indeed! I was just thinking when I saw the module, that a better board was needed. Something like the Pro Mini but based on the ESP8266. You must have read my mind. I especially like that you included the LiPo charger. This is just about perfect for a simple IoT solution.

    Except I would have named it “Io”. Then the shield-like boards that supply the Thing specific functions (sensors and such) could be “T"s. ;-)

    Good job folks!

  • 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.

No public wish lists :(
