Electrolyser designs - Free Energy Info

slightly different resonant point which did not match very well with the other cells. Bob had to go to the seriesplate design with accurate spacing and tight tolerance on slots and plates in order to get the resonantresponses to line up on all cells. Also, he found that some choices of electrolyte would not produceresonance at any frequency, though he is not sure why. Some worked well while others worked marginally,so Bob stuck with what worked the best for him - sodium hydroxide (NaOH) and potassium hydroxide (KOH).It needs to be stressed here, that every electrolyser build is slightly different from all others, even though theymay have been meant to be exactly the same. There will be small differences between the plates in oneelectrolyser and the plates in other electrolysers. The electrolyte concentration will be slightly different, theplate preparation will be slightly different and the overall magnetic characteristics will be unique to eachactual build. For that reason, the tuning of the completed electronics board and the construction of the bestpossible transformer to match the electronics to the electrolyser, is always different for each electrolyser built.The first step is to build the electronics control board. The methods for doing this are shown clearly in Bob’sdocument entitled “Boyce Electrolyser Project.pdf” which is in the “Files” section of the WorkingWatercarYahoo forum. Bob has designed a printed circuit board to simplify the construction of the electronic drivecircuitry. To see Bob’s design and to order one of these boards, you need to download and install the free“ExpressPCB” software which is located at http://www.expresspcb.com/ExpressPCBHtm/Download.htm andwhich can display his design files. The download is just over nine megabytes in size and contains twoprograms: “ExpressPCB” and “ExpressSCH”. Only the ExpressPCB program needs to be installed for you tobe able to place an order for a board.The design files needed for you to be able to order the printed circuit board, are located in the “Bob BoyceProject” folder in the “Files” section of the WorkingWatercar forum. If you are not already a member of thisYahoo Group, then you need to join at http://tech.groups.yahoo.com/group/WorkingWatercar/ which is a goodidea anyway as the forum members are always willing to give helpful advice. The “Bob Boyce Project” foldercontains the “Boyce Electrolyser Project.pdf” document describing the construction of the electronics.You need to use the ExpressPCB program to access the “PWM3F.pcb” file which is in the “Bob BoyceProject” folder, as this small 50 Kb file contains the design and construction information needed by themanufacturer to construct the board for you. Download the PWM3F.pcb file on to your computer and doubleclickon it to open it with your newly installed ExpressPCB program. When the file has loaded, click on the“Layout” option at the top of the screen and then click on Click the "Compute Board Cost", enter yourlocation, select the Two-layer Board option, then pick “MiniBoard”. Alternatively, you can get the board fromThe Hydrogen Garage for just US $20 at:http://stores.homestead.com/hydrogengarage/Categories.bok?category=ELECTRICAL+%2F+CIRCUITSalong with other useful items like an ammeter for checking the current flow through the electrolyser.When your new printed circuit board is delivered, you will need the components to be mounted on it. Terryhas set up a pre-filled order form for Digikey which you can use without having to key all the informationyourself. Just click on this link: http://sales.digikey.com/scripts/ru.dll?action=pb_view&pb_glue=1014385 toorder the parts which will cost about US $60 for US mainland shipping.The completed 3G board looks like this:18
