Finally converted the intervalometer yet again to beefier switches & an enclosure. Using lessons learned, it's now using the very reliable dip switches & slide switches from the 1st intervalometer + a very reliable battery connector to hopefully eliminate all the problems of the last 8 years of intervalometers.

Obviously, it's insane to invest all this energy in home brewing something that's $15, more reliable, & much smaller, but the parts are getting recycled instead of thrown away & it does exactly what it needs to do instead of requiring workarounds.

The dip switches have proven the most reliable way of setting mirror lockup delay, exposure time, & storage delay. LCD's had the problem of vanishing in cold weather.

Together with the super reliable wireless control. That gives all the shutter control required. The only next step would be a remote controlled pan/tilt mount, but there's no obvious need for it.

Now for a rousing XMas working on a UDP ground station interface. XMas was rained out again, so there was no point in driving anywhere.
