Hey whereswally, you mentioned a minor tweak in the PCB design... did those files ever get posted here? Also, glad to hear you got the boards (hopefully they are good... tho if enough people end up wanting these, a $100 re-order would likely be easy to account for with an extra $1-2 an order). How's it going as far as stocking the parts to populate the boards? (I haven't checked the BOM yet TBH, though assuming its not that many parts based on the board size).
I've been ordering so many small smd parts from arrow lately, just received my UniSolder 5.2 boards from pcbway yesterday... took less than 4 days from when I ordered to get them, and at an incredible price (they are almost giving away the < 100mm x 100mm 2 layer boards). But with 3 boards to populate, soo many little parts to buy (need to find a few more things before I have the entire BOM in my shopping cart... not exactly sure why, but searching for correct headers is a huge PITA for me versus all the other parts). Also finished putting together the circuit boards for one of the DIY Android spot welders... printing cases for it right now.. gotta program the arduino, and build the electrodes (just waiting on the terminals for the electrodes to be delivered). It's pretty surprising how easy it is to hand solder smd boards... always looked near impossible to me... but seems like the flux does half the work, technically don't even need a small soldering iron tip. The ONE recent purchase that drastically improved my PCB soldering was some 0.4 mm kester solder... always used a good brand of solder, but had MUCH thicker stuff (which still has it's uses)... but this thin stuff makes it soo much easier to do a clean job, so much more control over how much is applied.
I honestly just realized BobC had died... somehow glossed over that post when skimming the thread.... definitely sad to hear (TBH, not even sure how old he was.... or if it was an unexpected event). Hoping he was indeed old, and had a long life. I really appreciate anyone who is willing to share their work in an "open source" fashion, where their intentions have nothing to do with making money. Or even people who are selling their stuff, but at such a low price, where it's a fraction of what their time is actually worth. Seems like BobC contributed a lot... definitely a sign of a good person.
