I only ordered once from Chris, a Quark. Had some issues but Chris rectified it qiickly. Then I got it too hot with the soldering iron anyway. Only reason I haven't ordered again is because I don't feel like ruining another kit trying to build it
15 watt pen. When building a Quantum, put the tape under the Wifi chip and try not to slather solder underneath the chip. I had one go awry and I think that did it. The voltage regulator got hotter than heck and the unit would lock up. I wrote it off and three others I've built since then are fine. I have "cooked" several of Cris projects including a couple of Quarks at various times thinking they were goners but they worked perfectly for me. I can swallow something like that.
As an aside, I was epoxying the large capacitor to the board on a "brand new" Raven III. Stupidhead decided to use a spring clamp to maintain contact with the board and epoxy. I moved it on my bench and the clamp slipped and smacked the board.
The next day when bench testing, the Raven would reset with the slightest torsion on the board!! Dang! Since I didn't try to bench test initially before I tried to do the epoxy thing, I cannot honestly say I was given a defective unit. I kept it
and ate the cost. I fried an Easy Mega by connecting up a battery wrong. I had tested successfully before but I should have used a "checklist"!!! To their credit, Keith gave me a price break on a replacement. I very much appreciated that
as they didn't have to do it since it was my fault entirely.
