I am doing my first build thread on my Eggtimer mini and LCD RX. I had a great ordering experience with Cris. I read through all the online info several times before starting.
First laid out all the parts and got bench setup.
Soldering resistor leads on board to support GPS module.
I actually had to solder the 4 corners with the pins first. I could not keep solder from getting on top of the pads. So 1 pin at a time I heated the corners while applying pressure to seat module flush. Then soldered the rest. Notice protective tape did catch stray solder.
Then soldered the GPS module ground pads. I did have to take soldering iron to the belt sander to make the tip fine enough to go all the way in the holes.
Then all the fun small pieces.... And I messed up... Big... But I emailed Cris, and we came up with a fix other then buying a new board. First resistor went on ugly. and after continuing on, I decided to go back and clean up the first resistors solder joints. I dorked it up. Couldn't get the resister to flow solder up it. Overheated the pad and it lifted from the board. You can see the brown place where the pad use to be. next to 331.
The fix was to install the LED current limiting resistor inline. Its big and ugly. But it does work. Its attached to the 4th slot like the alignment pins were originally installed.
Finished installing all the other small pieces then prepped the RF board. Used 4 pins to hold its alignment and it went on real nice. Cover it with tape while soldering... Lots of small splatter.
