Hi Lindsay,

for protection what do you think about these polyswitches:- http://www.jaycar.com.au/productResults.asp?FORM=KEYWORD, they cut out when current reaches critical.

Cheers,

Dom

oops sorry, here are the hits on jaycar website on fuses:- http://www.jaycar.com.au/productResults.asp?whichpage=1&pagesize=10&keywords=fuse&CATID=&SUBCATID=&form=KEYWORD&ProdCodeOnly=&SPECIAL=&Keyword1=&Keyword2=&pageNumber=&priceMin=&priceMax=

there are many like quickblow fuses and temp switches, etc

Thanks,

Dom

For over voltage protection you would need a fuse and a crow bar.

But search google with "crowbar circuit".

Hi All,

Lol, while checking out this cool website i found something here that looks great:-

Smart Test Screwdriver

- Capacitor check
- Diode check
- Transister check
- Globe/relay/fuse/speaker/resistor check
- Locating broken wire
- Picks up static radiation of TV or monitor   <---this is what it does also
- Instantaniously checks AC power
- Earth disconnection check

"Smart" screwdriver is the latest in hi-tech test screwdrivers.It allows you to check / test the following safely:

- DC voltage test up to 250V DC
- Continuity check - L = 0 to 5M, - H = 0 to 2,000 Mohm
- Polarity check 1.5V to 36V DC
- Microwave leak detector greater or equal to 5MW/CM2
- Wrong mains connection check
- Check operating condition of negative Ion generators
- It is also a screwdriver!!!
- Supplied with comprehensive instructions

GK and all!

Please forgive me if I am being dumb here, as you know I am no expert in these things.

You just said you are putting 300 watts in and you have heat?

Am I the only one who thinks this is an expected result?  What have I missed and what has been discovered here?  I am assuming something has been because you are all very excited, perhaps its gone over my head?  Someone please educate me!



Regards,

Dave.

Dave............I expect alot of heat when consuming 300 Watts in a small device. I don't think anyone is claiming discovery, just foward motion with this project. GK is getting results that seem to be in line with what Lindsay and the Silent One say. I will be very impressed with myself when I can induce longitudinal waves in my copper cores from windings oriented at 90 degrees to them.

I will also be quite impressed if the permanent magnets stay magnetized permanently when exposed to AC fields and heat. I have to look back and see where these scope shots are being taken from.

Slow and steady progress will allow for a realatively safe environment and learning. I personally will not be satisfied until I can tell the energy GIANTS to FO. But that is my personal goal. If I get there you will all get a copy of the "Plans". I will not discourage anyone's efforts and I allplaud you all for having the balls to even start looking for solutions to the energy issues we all face together.

My synth chips are enroute.......my PCB will be next............TPU_004 will be wound exactly as GK and Otto have posted. Cosistent KICK is the goal for our class at this point, I believe, firing up the 200Amp service without the electric company will have to wait a bit.

Regards and good testing.......Gentlemen.................
