I bought some Nichrome wire today at Jaycar in Ballarat to hopefully make dew heaters for my ED80 and 100mm guidescope.
I have read about 15 websites today and read the posts in here about how to make it work and I am now more confused than before I started reading.
Some sites say just connect the Nichrome wire to a 12v power supply, others say I have to use a Pulse Wave Generator (whatever that is). Otheres say do not use a Potentiometer, others say use one.
I am very confused.
I'll tell you what I DO have so one of you might be able to help me:
I have an Apple PC power supply (13.5v, 1.0Amp, 15VA) and 4 metres of RES80 Nichrome wire.
What I want to do is heat both the ED80 and the 100mm Guidescope.
I won't be going back into Ballarat for quite some time so I am hoping I can build my unit without having to go buy more bits.
I know I have to cut the wire to length, but do I really need all the electronic gizmos to make it work?
Any help would be appreciated
P.S. I also bought Cloth Gaffer tape to house the wire in, and some sticky-backed Velcro tape to mount it.
