Finished up my 1590A build last night, well there are a couple minor touch up's but it's fully assembled, up and running. I'm happy with the results, happy to have a smaller mod but I wouldn't want to build another one any time soon. Even with a small 800 mAh battery real estate is slim and it was tedious work that tried my patience's more then once, using 12 ga silicone wire for the outputs really added to the challenge but I wanted this one done right.
A couple things became very apparent, having a temp control soldier station, assortment of tips, quality flux and solder really makes the job easier and does such a nice job. Helping hands is a must to hold the board and the wire in place during the soldering and keeping anything from moving during the process including cool down of the solder, there is no way to feed solder and get a quality joint if you anything other then solder in one hand and wand in the other. I was very pleased with the soldering I was able to do even with the 12 ga wire, in a lot of ways soldering is a lot like welding, heat, create a puddle and feed wire/solder to the joint.
I need some advice, those cheap alligator helping hands are causing me frustration, I need something better without breaking the bank. I don't need top of the line, I'm looking for something cheap but better then these, suggestions?
