Just a quick update on the single wire charging.

I can charge the battery from around 12.00V to 12.31V, even if I keep charging the battery so that a battery voltage
during charging shows above...

Dennis,

I use the long and narrow coils. For the coil check out 'Real Inductor Model'.

Hi all,

I started thinking about circuit boards for my on going rebuild of my 8-coiler. I used R-Charge boards on the original build,
but the weakness with this type of board is the thickness of...

Hi all,


further tests reveal the following:


1) DMM replaced with spare DMM display same high voltage.


2) Connecting DMM positive probe to the secondary positive terminal destroys the

Mikey,

check out this Avago spreadsheet, it calculates the resistor values.

Glen,

Dennis,

I tried different rotors, plastic, aluminium, aluminium with steel backing ring and iron.
The iron rotor with ferrite magnets perform the best.
I will be replacing the PM motor for a...

Photo 6 shows thick vertical line from the trigger wave
Photo 7,8 & 9 show same line at different timing

I have reproduced this effect two days running and until I get to the bottom of this I...

Hi All,

I have some strange results to share. I recently built an electronic trigger that uses a Arduino that works as follows.
Arduino receives opto signal from SSG this is received as an...

John,

The spikes are around 52V. I agree the dump voltage could be lower, I was so pleased at getting it working that I did not want to change anything until I was certain it was working properly....

Ed,

here is the circuit as requested.

Bob,

manufactures usually quote no more than 80% of the charger rating for connected panels, ie 8A of panels for a 10A tracker.
This is to give the system some slack during 'edge of cloud effect'...

Hi All,

I finally got my cap pulser to work as designed, I got through lots of mosfets on the way.

I am testing it on a 12V system on a bike wheel first.
The caps charge to 29.6V before...

Hi BobZilla,

HDPE is High Density Poly Ethylene, this is the stuff they make kitchen cutting boards from. My 8=Coiler is made from HDPE. HDPE does not machine
as nice as some plastics but it is...

hi all,

I was getting my cap pulser up and running this week but I kept destroying mosfets. I did get it working, see photo of scope shot.
I am now out of the dark with my knowledge of mosfets...

Hi all,

I found this spreadsheet on the web from Redirect 1 select spreadsheet and it will download. It has loads of easy to use calculation blocks.

Hi All,

Here is the info on the RPM Sensor.

1980
Circuit - Signal is connected to digital pin

1981
Photo - Yes the bike wheel shaft does come out of the workshop wall.
The resistors are...

MrRonsen,

have you published any circuits/sketches on the cap pulser?
It looks like you are using solid state relays, how do they perform?

Peter

Hi All,

I have decided to use an Arduino & data logger on my '1984 Machine' and 'Bike Wheel SSG' the '8 coiler' can wait as it is under rebuild.
The problem is to stop the spike from interfering...

Hi all,

just a quick update on the new rotor and coils.
It took me two weeks to turn an iron rotor, its not a metal I like turning. I recessed the magnets into the rotor, this took longer than I...

Theunis,

you are right about the ball park figure, the resistors should be 99M Ohm but as you say it does depend on the tolerance of the resistors.
The energiser that I am using is in 'Bedini...

Hi All,

On my latest build the voltage is greater than my digital oscilloscope can measure on X10. Although it can measure 400V, by moving the zero line below the display 700V can be measured....

Hi Faraday88,



Yes the rotor is just a disk with a separate hub.
After all the advice we have had in the past on monopole energisers having non-magnetic rotors, I am curious about the soft...

Hi Faraday88,
thank you for the compliment, I try to keep my builds neat and tidy. It also helps that I have a lathe/mill/drill combo machine so that I can get my ideas up and running quickly.
So...

Hi Faraday88,

I am using an ordinary PMDC motor. I decided on this approach so that I only had one variable on the build, that is the energiser. I was planning on replacing it with a window motor...
