    DC Smoke Generator

    Place your images here....link does not work (at least for me). Many will not follow links to strange dodgy sites......

    Power Reduction Query

    Fit a motor with a gearbox.... Sounds like it is too much load for direct drive voltage reduction of any kind. Gearmotor approach would normally fix the problem

    Dt 9205 DMM problem

    Sounds like it has been dropped and the display is now out of wack (alignment) or even broken the display glass.

    Help with LED Circuit.

    There were a few circuits around other than that which came from model railroad people.......used to make a welder simulation. The flicker candle one........... If you know anything with Arduino, this is a really simple one that could be easily adapted to Attiny85 module (Digispark to some) to...

    Lightning in a bottle

    You think that's difficult. Try stuffing blue spark in a can for standby electrical.o_O Scarce as hen's teeth too, just ask any electrical apprentice who has been sent out to get some.:rolleyes:

    Help with LED Circuit.

    Simple starting point would be to get some of those "flickering candles" at any $2 shop and modify the output to take whatever loading you require.

    Electronic flourescent tube starter

    Still, I'd chop it down and get rid of it if your house burns down. Insurance assessors don't hold your point of view I'm afraid to say.

    Monitor screen keeps dimming and turning black

    Backlight playing up, either needs replacement(most obvious) or repair (not normally done) I mention the latter as it could be the cable on the tube end burning off if it is fluorescent type or bad connection if LED. Shining a torch at an angle to the black screen will verify if the rest is...

    Power Reduction Query

    PWM module would be the best approach. Is the drive direct or through a gearbox of some description. Show the specs of the speed control you have and the motor details.

    Araldite Rapid, Cyanoacrylate & PCB material.. does it stick?

    Some types of plastic require acetone based adhesive. Otherwise you're trying to sail up the current without a paddle. You could try plumbers silicon, it sticks to most things. 24 hours to cure though.

    Can someone help identify this device?

    As "steam engine accessory" chances are "generator" ... :)
