Not unless it makes you feel good, I'm not doing the boards again!
stan2004 posted:I think the R1-C1 time-constant should be linear. So if initially measuring 800 msec using R1=1.0M, then targeting 950 msec would suggest R1=950/800=1.19 M, so 1.2M should do the trick.
Yep, it was a bit less than 800, and it shifts lower a bit when I actually solder the resistor in, obviously holding them in the holes isn't perfect. I actually have one that's right on 1.0 seconds with a 1.5M resistor soldered in, didn't try that with lower values. I also didn't have that many 1.5M resistors, so I'll get more this time. It looks like they're going to want either the 1.3M or 1.5M resistors to get close, seems there aren't any values between those.
