Bedini ssg energizer

Here is a pic of the circuit and connections.

ok, so the crocodile clips on the pot definitely aren't touching each other? Also, how many connections are there on that pot? 2 pins or three pins?

[Gpilot]

They are not touching. The pot has 3 pins. It is connected correct, where turning it clockwise increases rpm. Only it isnt increasing rmp. Should i go from 100 ohms to 50 ohms? Or should i go the other way to 200-400?

This question is a little off topic, but would it be possible to make a frictionless bearing/rotor using ring shaped neo's attached to the hub of the rim, and more neo's inside the mount?

The base resistor isn't the problem. You've already shown your sg can run happily on 600ohms base resistance. If the pot is having no effect, and it is operating as if it isn't in the circuit, then there must be a short across it. I've no other ideas on how to fix it I'm afraid.

There are people using magnetic levetation instead of bearings so yes, that's possible. But with a bike wheel the majority of your friction will be from wind resistance rather than rolling friction.

I guess ill get another 1k pot then. I have a 2k, and a 4.7k pot, but same results with those which is no ability to change rpm. When i bypass the resistor again, meaning no resistor, i can adjust the rmp a bit.

Something else i have noticed is my charging battery doesnt seem to be charging very well. My primary battery looses volts as it should, but the secondary battery never seems to charge as fast as the primary discharges. I havent seen the secondary battery stand above 12v for a while. When i was running the machine without the resistor, i was getting the secondary battery above 13.5v. Now, it seems to stay around 12.96v. I should at least be able to have 1 battery always above 12v if the machine is working right, and if i start with at least 1 battery above 12v. When i started, both batteries were sitting at 12.4v, +or- .2v.

Hello , ive been reading and trying too make an SSG , im a complete newb so be gentle with me , lol. i have built the little beast and cant get it too spin up by itself , i have tried a lot of the things mentioned in the replys here , for example , when coil is powered by 12v car battery alone it will repel the magnets , i have brough 5 of everthing too make sure i have spares , one thing i do have different too the schematics is the 1n4001 , i am using a 1N4004 will this matter ? All help is GREATLY appreciated , oh and i must say , IM HOOKED , lol great little hobbie this

Post #62

Dagwood go to post #62 in this thread and follow it step by step. DO NOT skip any steps or take anything for granted. Just follow the steps and you should be able to get it running. Also you will get a lot more help if you are willing to give more information. There are probably hundreds of Bedini builds on the internet and Youtube and a lot of them are not built according to the way John Bedini says they should be. So where did you get your information on how to build one? In other words what parts did you use. What transistor, what size pot (potentiometer), did you use a grain of wheat bulb in the trigger circuit, and how many turns of wire and what size wire did you use for your coil? What magnets did you use and how close are they? All these things matter and you didn't give us any info we could use to try and help you. All you said was it didn't work. I am not really trying to give you a hard time. I am just explaining why you haven't gotten a response any sooner. If you can post a picture of your setup that would really be a help.

Respectfully,
Carroll

PS: You do know that you have to give it a spin my hand to get it started I hope?

Thank you

Hello , thankyou for your reply , i was a bit hasty with my first post , i am trying to build a bedini SSG , i have followed the 2 main you tube tutorials being , sephiroth and jeff williams , i have downloaded the schematics from this website , Firstly , i made a coil from the specified wire sizes , i wound the wire on with care and put 850 winds onto the spool , i then used welding rods for the core , my core is 2cm , i then used a 2N3055 transistor to start my bedini circuit , i then have used a N14004 instead of a N14001 diode , this may be my issue with it not working , white stripe towards the base i soldered it on other end too the emitter , i then soldered the 400ohm resistor too the base end then soldered the resistor too the far right leg of the pensometer , then put it all together following jeff williams you tube video , the SSG repels the magnets but after i spin it with power connected it slowly stops , i know i need too supply more info and pictures which i will do today , one question though , i am using 1cm round ceramic magnets doubled up and my core is 2cm , will the magnets penetrate the core enough too trigger the transistor ??

[dagwood111]

Citfta , i did as you said too the letter , it dosent work still , but i have made progress , i get the magnets too kick away so power windings are okay , but when fully wired up with trigger wires i get nuthing as if no power, even if i swap them over , if i use a peice of wire from negative on the battery too the collector side of the neon bulb leg it kicks away the magnets , if i put the wire on bulb leg emitter side nuthing , im now wondering weather it's the 1N4004 im using instead of the 1N4001.. This is a head stress LOL.

Base resistance

OK, now we have some info to work with. That base resistance sounds way too high. That may be your whole problem. Most SSGs work best with about 100 ohms or less between the pot and the base. Your diodes are probably fine. Your magnets don't sound right at all. They should be rectangular, not round. They should be mounted crosswise on your wheel so they span across the entire coil. In other words if you are looking at the side of the wheel the ends of the magnets should be facing you. And of course they should be mounted with the north face facing out towards the coil. I am not familiar with the Jeff Williams videos but I am familiar with sephiroth. Anything sephiroth has shown or posted should be fine. If you get the right magnets and reduce the base resistance you should be OK.

okay , i changed the reistor too 100 ohms , still the same its as if it dosent get any power too the coil the magnets and coil behave as if there is no power when infact it has a 12volt car battery to it. Strange.. im just sourcing sum magnets , i guess thats my next step , one thing i dont understand is that when i remove the negative from emmiter and touch it on the colletor it opposes the magnets , but when i hook the negative back too the emiter its as if i still have the battery disconnected.

[dagwood111]

this may be a dumb question but here goes , i am using an old platic wire reel for my coil , there is plastic between the winds and the core ( the centre of the reel ) is this okay or do the coil wires need too directly touch the core ? sorry for such a dumb question but im at a stand still here

[citfta]

Hi Dagwood,

Your core does not have to touch the coil. You plastic spool is probably OK. I use old solder spools for my form to hold the coil and core and they work fine. Your magnets should be plain old ceramic magnets. You don't want strong magnets. If you live in the US just go to a Lowe's Home Improvement store and get some packs of magnets there. They are plain ceramic magnets about 2 inches by 1 inch by 1/2 inch. When you connect the negative to the bottom of the coil and it kicks the magnet away that is the correct operation. When you connect to the emitter and it does nothing that is also correct. The SSG will only run after you give it a spin by hand to get a magnet to induce voltage in the trigger winding. The trigger winding will then turn on the transistor which grounds the coil back to the negative which then kicks the magnet away and that is what makes the wheel turn. The SSG does not self start. What are you using for your wheel? If you are using a small wheel instead of a bicycle wheel it is also a little harder to get it working although a lot of people have used small wheels and gotten them to run fine. I have built both and didn't have any trouble getting either one to work but I have years of experience in electronics which certainly helped.
