Flame Licker Running a Generator and lighting an LED bulb

Well done, Jim. Are you using a stepper motor for the generator?

ive got three steam turbines and thre three matching generators . My plan is to have a turbine mechanically drive one generator that In turn will power another generator as a motor then power LED LIGHTS I just got the light and holders with bulbs I have a pair of 20x20 extrusions and a handful of tees lot nuts to fasten things together Once I get the universal wires made I’ll assemble it
Flame Licker Running a Generator and lighting an LED bulb. These small engines interest me a lot and they are capable of doing some work, a little different from my main hobby of toy steam and model steam engines.

ill try and come up with something I was actually going to try this with my little steam engine on compressed air but I keep having small issues with it the turbines take a lot of air for their size so I may have to get an air tank as I don’t think my compressor can keep up with them they need to run another 30 k rpm minimum to have enough torque ive got belt reductions for them so I may have to make some adjustments I suspect the gear belts won’t hold up to the load and rpm The motor generators have to run about 5400 rpm to be reasonably efficient but once I get one set up I’ll be able to experiment . It’s interesting as I designed a similar system for a series of high speed wire drawing machines using 40 hp electric motors they were r gear belt driven with no trouble . Those old motors hd U.S Navy stenciled on them so that’s where my idea came from
Please show me some pictures or a vid when you get it setup, I would be super interested.
Thanks!

Jim, what kind of circuit are you using to rectify the stepper output to DC for the LED?

i searched this quite a lot . Most use a bridge rectifier . I have a bag of them and parts to solder together I also have a smal bread board that I’ll try things out on I even got a new soldering iron an helping hands with mag glass also got s bag of terminal ends to fit my motor generators I’ll add these to the stepper motors too when I get to them I don’t know how much power these will take so I may invest in a small power supply I got a few battery boxes one tie . They are in the electrical stuff box the femal motor connectors are very hard to assemble but I found that there is a small indent that causes this by carefully squishingvthiscwith side cutter they can be made to fit much better I’m not much on electrics so I depend on internet videos . Most are pretty good for neophytes

ive got his video stored in y notes somewhere it’s where got the whole idea of a motor driving generato to do some additional work . Remains to be seen how much input gives how much output , nothing is free so you have to keep this n mind LED don’t take much power per light . I plan on making a street light arrangement. I tried to find scale rail rod ones but they all just don’t fit in my mind I have some 1/2” copper tube I thought I’d bend in an arch then slice a bit out and flatten it for a reflector of sorts I got a couple automotive dome light. Holders so I’ll use them I think after testing the holders were not very expensive nor were the bulbs I also hav a rotary variable resistor so I can vary the resistance as needed I suppose a small battery charger could be made too but that’s down the road always I may arrange the bread board so I can easily plug my multimeter in to measure as needed . I just wish I could get the steamer to work properly on compressed air
Chuck this is a pretty good video -
