Any electrical geniuses here ?

I'm still waiting for the graph!

[da SLUG man]

and there was me thinking that dimmer switches worked on a variable resistor, reducing the voltage that reaches the lamp!

incidentally, if you stick a diode in your fairy lights, they'll twinkle!


and on the spreader... is the wiring man enough?... this could be causing resistance and heat in the unit.

The heat is generated wherever the resistance is. No heat in your cables? They're fine.

Never heard of the fairylights thing! It'll be because they're run on AC, so a diode will mean half wave rectification and tiny gaps in the power. Must give that a go

ANDY REMEMBER TO UNPLUGTHE LIGHTS FIRST

Could you not wire it direct to the power source and put a dimmer switch in the circuit then you'd have completely variable speeds

Just a whacky thought

Always thought of ya as a bit of a "Roy Wood " Paul

There's always a Payback .. Co ya don't know where n ya never know when !!

If you take the rated wattage of the motor and divide it by the voltage, that gives you the amprage.

Electrical genius, Andy?
Hows about Mr. Modesty instead

thats like B.Obama wining the Nobel Peace Prize

Pop into your local technical college or university electronics department and they will be happy to design and build one for you, all they will want is usually for you to supply parts and allow a student access to do a project write up and maybe spend a day with you when you use it. We used to do stuff like that all the time at uni for local businesses, a donation to the department was optional but did ensure a less than 24hour response next time you have an issue....
