Having completed the construction of 10 sets of kit build 0 gauge points and 2 crossovers, I'm wanting to get together all the odds and ends I'll need for my intended layout when I start tracklaying come the warmer weather. I have a quantity of microswitches surplus from other 00 gauge projects which I could use for frog switching, but having done a bit of research on 'frog juicers' , frog switches etc, looking at the relatively cheap Gaugemaster DCC 80 'Autofrog' unit rather than the pricier Tam Valley offering, (and yes, I know it can handle up to 6 frogs) I was thinking along the lines of the DCC80 being pretty simple from the electronic point of view, 3 diodes, 2 resistors, 2 capacitors and a changeover relay, so it should be easy enough to produce my own version (I'm a MERG member, but only at a VERY elementary level!), as with my current points/crossover tally, I'm going to need at least 14 of these units. Components needed to build my own units will be very cheap, the relay likely being the most expensive part, but these will still be inexpensive sourced from Chine via 'Alibaba' or the like. So, who has used any of these units, are they as problem free as it appears from feedback, and given greater track electrical load of 0 gauge, are they reliable long term? Keith.
