Re: What size shunt to use ??

Thank's Richard, its pointed me in the right direction & it looks like these meters read of a shunt anywhere from 10-100amp & all are @ 75mV. Just need to get the correct size amperage to be safe. I will try one of these & compare to my amp meter. If it works, fine. If not, it was only a couple of q...

What size shunt to use ??

Hi, slightly off topic but hoping someone here can help. Apart from trains i also like RC electric model aircraft. Now the larger electric planes can run at quite high amperage, so i thought it would be handy to fit an ebay volt/amp meter to the plane permanently as you can test on the ground what a...

Is 20 volt pushing a points motor

Hi, i have an old laptop power supply that i was going to use for testing points. Is 20 volt pushing a points motor/coils?? or should it be OK.
Thanks

Re: Just ruined my XU2175M XURON TRACK CUTTER

Just used mine to chop up and old rabbit cage which was made from 1/8 wire, they chopped through that lot without breaking sweat. They will be the last set of pliers you will buy so well worth the money. Laugh! i read that as the rabbits didn't break a sweat. Not sure how accurate a rabbit would be...

I use those expo ones linked above, not found anything they can't cut without any sign of damage.
Ebay sell them at £17 inc P&P "Every little helps"

Re: Will the DCC Concepts AD-S8sx LED's need a resistor??

Thanks Brian, you have explained it a bit better. I didn't want to connect it to the power until i had connected everything up & wasn't sure of the led output voltage to work out a resistor. So, if i start with a 640k on 2 of the three legs "red/green" & if needed go up to a 800k if i want it not qu...

Will the DCC Concepts AD-S8sx LED's need a resistor??

Don't want to power up my DCC Concepts AD-S8sx until everything is connected. On the AD-S8sx it has the facility to run LED's for signals, IE red/green. I have run these back to a mimic panel. Question is: I am using a 3mm Bi colour 3 leg led's at the mimic panel. Do these need a resistor.???? or is...

Re: Bi LED's with straight legs

I have gone with 5 mm holders & they dont look as bad as i thought. A bit of heat shrink on each led will take up any space & look ok. A bit of black or blue tack to hold the led in place from behind.
