So I'm sure it's been discussed somewhere, that pin 13 of the FV-1 chip can be grounded to use the 8 internal programs on the FV-1. I'm sure folks here have added a toggle switch to ground for switching "banks" of eeprom using this pin 13 trick.
So, the MOD I'm actually bringing up is …. that R5 on the Arachnid board is only 10K. If you ground this, you are adding more load to the 3.3v regulator IC and turning more power into useless heat, which is bad, m'kay ? So I've been using 100K resistors for R5, copying what the other three switch inputs (for the 8-way switch) are doing.
This way, grounding R5 at pin 13 will not tax the 3.3v power regulator.
Suggestions or Comments ?
P.S. for Arachnid, solder your toggle switch (to ground) at the pad under R5, do not try to solder near the FV-1 chip itself !
