OXO Posted July 8, 2005 Share Posted July 8, 2005 I hope to some how create a power controller to adjust the amount of juice being used as its an AC mains jobby!!.You can get controller box's from Maplins Electronics cant you were by you plug your AC mains adapter into the box and there's a Lead from the box to supply electric to your heater strap. The box has the Amp's settings of which you can change to suit whatever appliance you are using..I seem to remember seeing one a while back Rob dont take it as Gospal i may be wrong..James Link to comment Share on other sites More sharing options...

Astroman Posted July 8, 2005 Share Posted July 8, 2005 I built my own dew zapper for the SCT out of 1 watt resistors, some wire and some heat shrink tubing. All together it cost about $10 US. It runs on a 12V battery, the same one used to power the scope, or my truck and works amazingly well. I've only had to use it 3 times, two of which were up at the Grand Canyon, but if you build one, it should work for you, too. I'd be happy to write an assembly procedure for you, if you like. 1 Link to comment Share on other sites More sharing options...

Ant Posted July 11, 2005 Share Posted July 11, 2005 That would be great for me as well astroman. Make it as simple as possible - cause I'm a bit of a dope whern it comes to things like that! Ant Link to comment Share on other sites More sharing options...
Bill Harrison Posted September 20, 2005 Share Posted September 20, 2005 Love the Idea,I am an Electronics student and have most of the bits and pieces to hand. I have a few of my own idea's as well. I hope to do quite a bit of observing this winter so this can be a nice little project for my 5" refractor as the dew shield on it is not great. Many Thanks for the inspiration!!I also have some bright red LED's and am looking to use these to make a Red Night Vision Torch with a few differences. When I have finished I will post it on the on the forum. Regards,Bill Link to comment Share on other sites More sharing options...
Rob Posted September 21, 2005 Author Share Posted September 21, 2005 Sounds good Bill... I did cheat in the end & bought an Orion Zapper for £35! however, I'll be real interested to hear how you get on. Rob Link to comment Share on other sites More sharing options...
