:: I would not make one :: from that diagram. Some text is illegible and I haven't found the :: FET Granted, the SMPS circuit is difficult to decipher and this one is not exactly clear. I was in fact going to email the OP and see if he'd like me to convert it to a CAD PDF/JPG version, as and when I get spare time.

Mr. Barnard's statement above is not only negligently or maliciously libelous and deeply offensive but also flat-out wrong. Quite an impressive accomplishment for so few words.

Jan actually posted this link weeks ago elsewhere, and he's already thanked me publicly and appropriately for the several times I've helped him throughout his development processes (his intro to the 18F.K series), so I hardly think either of us need any "coaching" on how to conduct our communications. To date our interactions have been effective, productive and marked with far more mutual respect and humor than is evident in this allegedly moderated forum. Jan has made amazing progress in a very short time. He probably cut a few corners along the way, and that's to be expected. It ain't the ceiling of the Sistine Chapel, folks. It's not always easy to provide free help when there are pressures from many paid and speculative business projects, but there is some apparent payback when the results are made freely available as Jan did. >I found the "diagram" comment entirely reasonable, but I know what >it's like being on the receiving end of "smart' comment when it misses >the main point of what you were conveying. A bit of appreciation along >with the comment will usually make all the difference. There's nothing whatsoever wrong with his diagram, and I suspect he intends to leave it just as it is forever. It's free after all, and making it easier to follow might only cause him problems. It's obviously his original working diagram, and it looks just like the ones that I produce when in creative mode (including the flux stains), before I get another of my engineers or techs to beautify it. It's GPL and if anyone wants to improve on it, they're free to do so (provided they follow the GPL terms). BTW, Jan is not particularly thin-skinned-- and he does tend to speak his mind. >Best regards, Spehro Pefhany --"it's the network..."

The number of times such projects start as 'back of cigarette packet', 'back of envelope' or 'table napkin' sketches are myriad. Somehow I cannot quite conceive Olin doing a full CAD schematic and board layout before starting on his helmet lamp. Maybe once the bugs are ironed out and wanting to publish it on the web page then maybe the sketch does get tidied into a CAD schematic. Looks like a nice project, one that could be experimented with.

It gave me ideas... I have a portable scope, but I think about giving one simple scope for each of the company's field technicians, for trivial diagnostics. It happens also that we use a lot of this model of display in our products and we have lots of them in stock. But I think I would use some PIC32 devices I have lying around.
