One of four done! (Whoot) It took me about 7 hours - let me explain. I soldered my first PCB (SparkFun kit) 4 days ago. I set everything for one LE on the dining room table and did a walk through. Watched the videos, printed out the assembly manual, used it as a checklist, fired up the iron, burned my hand 'cuz stupid me forgot that it does get hot, and I should have moved it before I turned it on.Play w/grandsonPlug/solder/inspect...Plug/solder/inspect......Play w/grandsonSoldering went great! I only re worked 7 solder joints.Play w/grandsonDid the power up test and got the two LED's!!!Play w/grandson........THIS IS SOOOO COOL!!And like the post above about the dongel (I did not get one yet), I'll go give it a try soon.
Not sure why the firmware would be an issue it should be the same firmware we have been putting on them. Maybe the file has got corrupt. another reason I plan to stop flashing them in the coops so that the user get a programmer since you should have one if you are building this stuff we do updates all the time.
