Fusionchip's Bedini Feedback to Source!!!

Al:

You better slow down there.  Pretty soon you will be running your house on just one fan and a JT!  Shortly thereafter, all of these fans will be removed from the market, ha ha.  Seriously, great work with this device of yours.  My fans are coming and I don't know if I have enough skills to do this but I am going to try.

Hi all

Well I've got the fan working (even with the reversed diode on the base) but I still need a few components which the electronic store didn't have or was too expensive.

I'm trying to find equivalents of the SK3606 which seems quite hard to find around here, I added a Scosche 500k Micro Farad Cap because I didn't have a 440 uf 400 v cap and they were just too expensive at the store, I played around a bit with it last night and tonight but finding the sweet spot is really hard to get, it ran for almost 2 hours last night before losing voltage so I think the fan is ok but the SK3606 and possibly changing other things might help.

Regards,
Paul

@all

I found a datasheet for the sk3606 and related parts:

Thanks nievesoliveras

I was looking at it too a couple of days ago but it's trying to find one locally that's the real challenge for me, I'd be better to order them online if I could find them, these are the specs I found of the RCA SK3606:

SK3606 Silicon Rectifier
       
V(RRM)(V) Rep.Pk.Rev. Voltage=200
I(FSM) Max.(A) Pk.Fwd.Sur.Cur.=300
V(FM) Max.(V) Forward Voltage=1.5
I(O) Max.(A) Output Current=15
Package=DO-5

VEry Good getting 19 ohms resistance coil feedbacking . Hmmm . well I am glad you guys are at least no i'm not BSing you as this is not My nature and i was Leary   to share this good discovery when so many others out there have similar projects and simply wont give there setup and not give you a simple do it rather than Bsing you have to understand it before i let you have it . I don't care if i never Understand it . I am Happy with it just the way i built it and really am tickled you guys are getting some fun out of it  so have fun .If you finally figure out Why it works then yes I will Copy it down and treasure it for ever .  I am working on several NEW feedback systems that involve another secondary that is rectified ,stored and flashed back to the source . Yes it works but i am not releasing My method just yet .just a little tease  :)This is going to go good with a Stepped up version of little baby48 . a 117 volt ac fan .. If you ever have played with ac motors you know the generate high output if spun fast so i will start tearing the fan apart soon and rewire it like one of these and to be sure get 20 or 40 volts off it running a 12 volt batt. .I'm ready to run an inverter off these babys . I can run lights of this one . I'll post a picture in a bit . Its a jt (Joule Thief that draws 1 ma) on a pot and runs while selfcharging . at least it will do something besides Be a Squeak Toy  )  Also i want to try and wind two of the fan coils with No#32 wire and see if it will induce another voltage to store in a Cap . There is plenty of room on these 48 volt fans .

Despite me having had the 'effect' using a 24V fan, the 48V sounds much better as I think you said that you can 'fry' batteries with yours if you leave them charging.

From the sound of your progress towards running lighting off inverters it sounds like you are well on the way to teaching John Bedini a few tricks!
