  • Question about that blynk timer (first one) and twitter (last one) demos… Does the blynk app on the phone need to be in the foreground for it them work?

    Say, you want to use your phone for something other than the blynk app (or you just rebooted the phone and haven’t re-launched the blynk app) when one of those timed events (twitter demo included since it appears to want to take an ADC reading on a timed cadence) is supposed to happen. Will it?

  • You know, the more I think about it, I realize that I’m only half joking here.

    My local maker group (Barrel of Makers in Wilmington, DE) is a registered non-profit and is just starting out so we don’t have much equipment yet. It would make a nice $1k tax deduction should anyone be interested. I just want to put the thing together and have access to it. :-D

  • Well, if I were to do it I’d design a custom board that would take the switches directly so no need for the breakout board. That brings the parts cost for the switches down to $87.72. I’d probably publish the PWB design on OSHPark so anyone who wants it could order the board. Do the schematic and layout in KiCAD with the project on Github, and the case and key-caps on Thingiverse. Totally open-source keyboard.

    I’d offer to work on it, but I don’t have the money to prototype the schematic and first run of boards. (Probably looking at a grand just for prototyping as long as multiple revisions aren’t needed…)

  • If only I got a tax refund instead of owing more money… My birthday is coming up if anyone wants to buy me the Shapeoko Deluxe Kit for me to assemble for my local maker group, just tell the customer service person to ship it to the address on my account. ;-)

  • Carefull, stating “Wholesalers like eBay are somewhat trustworthy” isn’t quite accurate. eBay isn’t a wholesaler, it is a purchasing/selling facilitator. Maybe better language might have been “Wholesalers like who are found on eBay are somewhat trustworthy”.

  • The lettering on the gold nails, Elvish script I assume? The inscription of the One Ring?

    Good detail work on it.

  • Ok. Egg on my face. I guess I hadn’t looked hard enough at multiple examples. The one or two examples that I saw were just pushing a single field per record so I didn’t realize that phant supports multiple fields per record.

  • Thanx. I’ll look at that tutorial.

  • Thank you for point #2. “Cloud services can be unavailable.”

    I don’t know how many projects that I’ve seen that seem to expect the internet to actually be there at all times. (Shawn’s breatholator tie for instance.) I’d like to see an easy to implement (and later analyze/plot/sort/etc.) method for phant (and other IoT services) for a date/time stamp to be associated to a data point from when the device took the reading, not when the cloud service received the data point. Most of them seem to take a single piece of data and assign the date/time when the server received that data point.

  • Same here, sort of… I had made a change (40-pin DIP to 44pin PLCC) on a board that had 3 separate plane pairs (digital power & gnd, analog power & gnd, and patient isolation power & gnd). When we got the boards back and populated the first 10 with components. The test & calibrate department found that two of the 3 planes didn’t have any thermal relieves to plated holes and vias… ooops… I think the patient isolation pair were one of the two unconnected, so they were really isolated. ;-)

    I never did live that one down at that company. Luckily for me an engineer had signed off on the photo-plots so there were plenty to help share blame. Check-out procedures were enhanced after that…
