I was going to ask ya Craig what freq you will choose for your new mod I saw it has a select-able range.
Tarted it up with a nice finish and a fat daddy sprung loaded connector:I'm pretty pleased with how it came out!
You really need the 220 Ohm resistor - 200 Ohm pot combo there. The problem is if you turn the pot full swing, you can take the voltage adjustment pin to ground which full swings the regulator to unbounded output voltage. It's bounded internally by duty cycle, but it's possible to damage the regulator that way.Another suggestion is the unused pin on the pot should be tied off with the the lead going to the regulator. The reason is that if there's ever any intermittent connectivity with the pots' wiper (which can happen due to wear), there will still be some resistance in that line. Leaving the unused pot terminal floating is probably not ever going to cause a reliability issue for the regulator, but it's better in principle to tie it off.
how do you tie off pin 1
