Anyone worked with or build one of these? They look pretty interesting. I'm not sure how useful they are for anything, but the do look interesting. ...
Hello Everyone, I'm Glen Ray. I'm a 55 year old kid who works as an industrial mechanic at a semiconductor factory. I've built a few HV machines in the past...
Welcome Glen, I have used that type of roller on two of my machines with good results, though I have not covered either with tape. I have covered one with PVC...
I recently acquired some surplus parts from two microwave ovens, including two whopping capacitors. I've messed around with them, trying to charge them with my...
... I just put five microwave oven transformers and three magnetrons on an auction site (not eBay!). Anyone interested is invited to visit www.auctionarms.com...
... Thanks for your response Todd, It sounds like the same roller. With a PVC roller did you put the PVC on top? Did you use PCV cement to coat it or have...
Hi Glen: Just thought I'd say welcome aboard and add a bit to the roller discussion. I use PVC on top and nylon on the bottom with a vinyl coated belt. Just...
I just attempted to create a photo folder named "Just a Thought". It's the first time I attempted it. I did not find a "DONE" button so I'm guessing the...

All the Wimshurst machines I've seen use contacting brushes for the neutralizer bars to transfer charge between sectors, and non-contacting points to transfer...
There's a book titled "Homemade Lightning" by RA Ford (ISBN13:9780071373234). http://product.half.ebay.com/Homemade-Lightning_W0QQtgZinfoQQprZ1898035 In his...
... Yes, but the machine will not start by itself and will easily stop and have to be started again, with charge from and external high-voltage source applied...
... Dick, Well, it's about time you have a go of it (taking good still pics of direct-from-the-terminal sparks with your big VDG). I like all the information...
... I've tried this with my digital camera, but never got the timing right. I think next time I'll use the 'movie' function of the camera, then see if I can...
Hello Hank; So what's wrong with lifting a frame off a video disc?? Using traditional methods I would never have succeeded in capturing the VDG + Bucket in ...
Glen, Sorry to take so long to reply, but have been involved with other "stuff" lately. Nothing fancy, I used some of the rubber belt material on the nylon...
In an attempt to improve our Bonetti (sectorless) Machine, we have added Leyden Jars. We have started with two 12 cup French press coffee carafes. They are...
... Nothing at all. I have a movie I took just a few days ago (with a Canon A540) from which I'm going to try extracting frames. It surprised me that most of...
The comment about Leyden capacitors reminded me of an unfortunate incident at the last February static demo in the High School auditorium: One of the Leyden...
While looking for something else, I spotted this: http://www.northerntool.com/webapp/wcs/stores/servlet/product_6970_21336_21336 A 7.5kv solar charged fence...
... I think I've figured out the problem with taking pictures of the sparks with a digital camera. Most digital cameras have automatic noise reduction that...
never tryed one of those but I have used an air ioniser can get 1 inch sparks off a collector ( aluminium pot plased on insulator styrofoam cups ) with it...
... Sectorless machines are very sensitive to the humidity in the air. Make it sure that the disks are clean and dry. Use a hair drier to heat them a bit...
You can never have enough good spark pictures! I've just posted a few reasonably good spark photos from my effort, made possible by the many excellent posts...
Posted some photo's of my build on the site (Kevins 1st VDG build). The same photo's are on my site (see below) with much more detailed comments. Cheers!...
The 50 ua figure seems to have been beginners luck. Got that current consistently for a day or two, then saw it drop down to ~10ua. Thought at first there...
