How to kill and rescue a DX-7 Radio
Well to be honest, i am no the best soldering guy but i managed after an initial learning curve (Killed a XBOX once) to extend my soldering skill. Now i liked the fact that i could extend the battery life of my radion controller by replacing the voltage regulator. You can find some details here: http://www.dimensionengineering.com/appnotes/spektrum_mod/spektrum_mod.htm
Now to the ugly part, i desoldered the old voltage regulator and everything whent fine, but i made a misstake with the last pin (VIN) and the pin comes of with the traces on the pcb (short piece of it). After screaming some strange sentences...i calmed and started to bring out my voltmeter and where looking for traces and lucky me i found some. Because VOUT and GND where still intact it was a piece of cake and did cost me only to add a small cable from another connector to the voltage regulator.
I did test it within my basement of the house and it seems to work. PUH! I have to test it in the wild maybe tomorrow. Anyway i am happy that now my readio is working again.
Here are some pictures:
1. The destructed traces (The most left one)
2. Completed fix (Still ugly soldering but i was very scary to kill others again
