Coil Power Supply

27 03 2010

Made some progress on the coil power supply. Soldered an extension cord onto the 120V side of the 600V step up transformer:

I crimped on terminals to the 600V side to connect to the rectifier:

Success. I slowly brought up the variac and metered 500VDC with ripple:





Electron Gun

Now thats it’s so much easier to open and close the conflat, I decided to take another shot at the electron gun. This time I got it. These are air plasmas.

You can see an electron beam evident in this photo:





Upgrades

27 03 2010

Did a few upgrades on the system today to make it easier to work with. Backplate nuts allow you to tighten the conflat with just one wrench which makes it much easier:

I added a piece of 80/20 to support the weight of the HV feedthrough. This makes it much easier and safer to install (I dropped it and broke a piece before):





New Arrivals

Some alligator clips for the FLUKE voltage meter.

Parts for the coil power supply:

SCR (844-VSKH91/14P). Not sure how to wire this up.

SCR schematic:

Rectifier + spare

Power resistor to bleed the capacitors:

Protection Diode + spare:

More conflat gaskets:

Back plates for 8″ conflat harware. These make installing conflats much easier needing only one wrench:





Speaking of Capacitors

27 03 2010

So I bought this capacitor a while back and kinda forgot about it. The other night I took it out of it’s crate and put it on a dolly. It’s freaking heavy at 86 kg (190 lbs).  It’s rated at 16 kV,  390 uF…. storing 49.92 kJ (kilojoules).

Now we have a power supply capable of charging this thing.

Here is what I’m thinking: 16 kV is enough potential to drive a fusor grid. So basically charge this thing up and release an very high current 16kV pulse into the fusor grid.

This capacitor is probably the most dangerous piece of equipment I own. It scares the shit out of me.





Hallelujah!!

Hallelujah, the Kickstarter funds have cleared!!!!!!

So after the Kickstarter and Amazon fees we have $3,428.32 to work with. Beyond that some of the rewards have a cost of goods sold that has to be covered.

I’m going to order the remaining parts for the coil power supply tonight!

We are back in business!





Hired!

20 03 2010

Great news! I’ve just been re-hired by Gucci for a 3.5 month contract doing ruby on rails development.

Although we have just completed a successful Kickstarter project, it does not cover my personal living expenses.

I will be working 40 to 50 hours a week, so I will have less time for the project. However I expect to make slow and steady progress on the nights and weekends. This is a much better position than the last two months, where I had all the time  - but not enough money to buy necessary parts.

I start Monday.

In other news I was able to initiate the funds transfer from Amazon Payments (they do the Kickstarter money handling), so I _hope_ those funds will be available in 5 days. The first purchase will be the remaining parts for the coil power supply.

We received 2 of the 10 capacitors for the power supply. I got these cheap on ebay. They are bigger than I expected:
