Guys I'm really really really excited as EVERYTHING works as envisioned !!!!!!
Tonight I managed to solder the fist SMD IC in my life to an already tiny PCB....
I first glued the chip to the board which worked....but the thing is so freaking tiny that some glue managed to make it's way under two pins of the chip, but I only noticed that when I started soldering.
The first side of the chip actually went pretty easy to solder, all 4 pins were soldered right away and I removed a bit of excess solder with some solder-wick.
The other side turned out to have the two pins that had some glue under them. This resulted in the two pins not getting soldered to the board. I used a tiny microscope to check this visually but also could measure it.
Now one of the pins I actually didn't need, but the other was GND. So what I did was an old trick which I've perfumed before but not on this tiny scale, but I managed to make a bridge from the pin to the PCB with a tiny bit of wire......
Anyway...I wired up the PCB.....connected all the connections as planned and then it was "D-day"....
I first only connected the AC power supply. As expected nothing happened so that was the first good sign.
Next I pressed the Power ON button of the Lynx and it fired right up !!!
Let the intro screen come up, pushed the Power ON button again and sure enough it turned off !!!
Exactly as planned
SO the basic on-off works !
Next I connected the tiny test LIPO. As expected the yellow LED for charging turned on.
Then I removed the micro-USB connector from the AC supply. I turned on the Lynx, started the stop-watch and sure enough the Lynx turned off after about 4 minutes, just like it is supposed to do on the Lynx I !!!!! I could immediately power it on again, so it was not the battery going low, it was simply because the Lynx "knew" that AC was not connected ( [AC connected] low ) and following this it activated the Power On signal (which I have inverted through U6), which signaled the LTC2950 to shut down power.
SO......I've done it !!! Everything works as planned and hoped right away....which I'm pretty happy with.
Again, the ideas for the Adafruit 1000C and the LTC2950 was entirely Cowdog's, but I was happy to make them for real.
I made some video but it turned out to be pretty long and my iPhone stopped recording because the memory was full, so I'll make and upload a video a bit later
Now, everything is still installed with temporary long wires but now I can shorten all the wires and install the PCB's on their permanent spots.....
