Rob Posted November 1, 2010 Report Share Posted November 1, 2010 (edited) Hey guys, Ive decided to build another diode controller but I have a question for the electronics gurus. What dia wire do I need as a minimum to carry the current. Typically we run RTR from SCX to NSR cars nothing really super duper. Looking at what is inside the parma economy handle its about 1mm dia wire. I have some .7mm dia wire in rolls would this be enough? Im bored out of my brain after having a month off work due to an infected leg and need something to do!

FLY in the wall Posted November 2, 2010 Report Share Posted November 2, 2010 (edited) Here are some general guidelines AWG vs. current There is a trade off between size and flexibility. We rarely see more than 2 amps on the power supply so I chose .75mm as it is what a computer power supply lead is. Easy to find, 1m long. just cut the plugs off. Inside my Parma the small wire between wiper and chassis gave up. I used a piece of solder wick. Getting the resistance as low as possible is important. Shorter is better. Mine is long so I can sit down with a beer. As you are laid up and talking about flexibility: Tommy Cooper went to a yoga teacher and asked "Can you teach me to do the splits?" Teacher: "How flexible are you?" TC: "Well I'm free on Tuesdays" Edited November 2, 2010 by FLY in the wall Quote Outside the box looking in. ------------------------------------ You don't own stuff: Stuff owns you! ------------------------------------ Having a cold drink on hot day with a few friends is nice, but having a hot friend on a cold night after a few drinks - PRICELESS.

dangermouse Posted November 2, 2010 Report Share Posted November 2, 2010 Did you see the thread on Slotforum, about building a club controller? Also Richard posted this about a controller chaps in WA have been making http://neophytte.mine.nu/forum/forum.pl?fi...c_id=1277296367 I am hoping to have a go at making one myself one day cheers DM Quote Link to comment Share on other sites More sharing options...
Rob Posted November 2, 2010 Author Report Share Posted November 2, 2010 Hey thanks for the Links DM, im building a diode one for now I might try something like that for the next one. Quote Regards Rob Link to comment Share on other sites More sharing options...
kalbfellp Posted November 2, 2010 Report Share Posted November 2, 2010 Rob: try and find some very flexible cable, I use cable that is normally used for meter leads,I think is has 75 strands and is 2.5mm area. The 0.7 diameter seems too light to me and probably too stiff. DSE used to carry "ultra flex" cable that was great for controllers. Armchair Racer also carry great very flexible silicone wire in various colors,expensive BUT worth it.

stoo23 Posted November 4, 2010 Report Share Posted November 4, 2010 Yes I agree, Many of the available Silicon variants are also Oxygen Free, which Is a very good thing, especially running DC current. Have a check at your Local Electrical wholesaler or even perhaps a Live entertainment Rental company especially Lighting Hire companies, as they Invariably use some Very suitable Silicon Mains cable that is Both Flexible and of more than enough in both strand count and cross sectional area. Anything from .75mm squared should do the trick. Quote https://ascra.com.au/ https://aussieretro.ascra.com.au/ Link to comment Share on other sites More sharing options...
