Good Evening All, Things are still moving ahead slowly here at Courtiestown but progress is being maintained, I just wish it could be faster!! We are hopeful...
Let us see what you are using to disulfide your batteries.... Can we list the schematics with parts list to compare these units with one another? MAYBE some...
Sounds great to me except that I have not personnally seen any good results. The results appear to be like the Phantom, you hear about it but see nothing. I...
It depends on the fault with the gel cel. If the plates have air pockets from overcharge/overheating, they're food for the recycle pile. If the gel cell is...
Jim, There is no great secret to the desulphators I sell. They are very closely based on Alastair Couper's original device as per HP 77. In the Basic device I...
Hi does anybody know if the SFP9540 Mosfet is a suitable equivalent to replace the FQP8P10? Also is there anywhere on the web where one can look up equivalent ...
Peter, The device you mention can be substitued for the FQP8P10 I use in the Basic Pulser. This device itself is a substitute for the IRF9Z34 as a near...
Look on the Internet

Hello, I'm glad to find this group as I've been reading the ezboard web forum but it appears to be more or less deceased. I'm in the process of building the...
Ashley, As you're probably aware the original API-Delevan inductors were rated; 220uH was 2.025A 1000uH was rated 0.39A so this gives you a clue as to the...
Hi Richard, Thanks for the quick reply. Actually I wasn't aware of the original ratings, in fact until Tuesday night I didn't even know what the heck L1 and...
... The Jaycar 220 uH looks good. Can't see the RS 1000 uH, but if its the 1.6 A unit it will be fine. On electrolytic capacitors - you can use caps with a...
... Hi Ed, thanks for the advice. ... Ah, I suspected as much. Oh well, it was only $4 for 100 :-) I daresay they'll even give me a refund if I ask. I had...
Hi Ashley. I have found that when you change the power parts (mosfet, output diode, "C4", and inductor set), the pulse timing also needs to be considered and...
Hi Rick, Thanks for the good advice. I'm trying to keep as close to original as possible, I think I've done pretty good so far (at least I hope so!) After...
Rick, This implies that you can tell us 2 more things: What is the free software you chose for this and you have an already designed pc board file. Would you...
... http://www.flickr.com/photos/7339875@N08/ That's a link to artwork for a desulfator I made using the free Eagle software I mentioned. It is a modified ...
... The above link will bring up an un-related photo as well as the artwork jpg. I should have added that the flux paste photo has nothing to do with this...
Hi Mike. The free software is eaglecad, found at : http://www.cadsoft.de/ As for the layout, I have not got a finished board for the standard pulser, the one...
Mike, As Rick says I have a simple PCB which may make your life easier if the components you have fit the space available of course. Regards Richard ... ...
Huge thanks once more to everyone who's offered help. I couldn't have done it without you. Over the weekend (with the help of my more electronics savvy...
... Hi Ash, I get a session expired when clicking on the links you posted, so can't see what's there. Regarding the routing: I drag the parts to the board and...
Hi Ed, ... Ah, one of the problems with the RS components website. The inductors I bought are RS Stock No. 228-551, while the alternatives that I think I...
Hey, now that I know I can sort of ignore the yellow lines, I've actually managed to get all the components positioned on the board and manually drew the...
... Hi Ash, The 228-551 is a better coil. The 489-0122 is a max of ~ .5 amps, the 228-551 is > 3 times that. I've used numerous inductors, and the 228-551 is...
Hi All. If you DELETE traces, you are also modifying the circuit and as you have seen, it is a pain and, in all likelyhood will eventually lead to an error. If...
