What is it, and what isn't it?
If you've visited my Tech Notes pages, you've already got a good idea of what to expect from the Tech Notes collection. It started out as about 1,000 pages of scanned sketches and notes in the first edition, increased to about 1,400 in the second. In the third edition, it’s up to a bit under 1,600, with new sketches added for the Minolta 35 LTM rangefinder, Nikonos, the Yamato PaX, the Praktica FX and a couple of additional TLR models, some new material has been added for Leica and a few other cameras, and the “General Notes” has been expanded to add some new material (and some of the old stuff has been retyped to make it easier to read). Oh, yeah, almost forgot: I’ve added some MORE CARTOONS too!

The collection is NOT a comprehensive repair guide on any camera, although in some cases it does go into some depth. These are sketches and photos I made for my own use and represent repair work that I have done over the past 30 years. Some sketches are better than others, some go very deep into the camera and others may be very brief, depending on the nature of the repair work that I happened to do on that model. It tends to assume that you have a basic knowledge of camera repair going in, its purpose is not to teach you how to repair cameras but to provide specific tips to help you deal with particular models – many of which are offbeat or non-mainstream cameras that you might not find discussed much anywhere else.

I don't have a complete list of every model of camera included, but this snapshot of the folder tree may give you an idea of what to expect.

What software do I need to use it?

Every file in the collection is in PDF format, so the only software that you need is the Adobe Acrobat Reader. You probably already have this on your computer, since pretty much everybody uses it for pretty much everything – but if you don’t, it’s a free download from Adobe - see the link at the bottom of this page.

Is there a money-back warranty?

No, Sorry. Please look at the Tech Notes pages and satisfy yourself that a thousand pages of the same sort of stuff is worth $15 before ordering the download. If for any reason you have difficulty with the download, I'll find a way to make it right.

Okay, so what do I get and how much does it cost?

What you get is the Tech Notes collection in PDF format, at the moment about 574MB of data sorted into 253 folders based on camera type, as a download processed through Dropbox.

The price is $15 for the PDF download.

I will also do my best to answer any questions that you may have later on if you find something is not clear or you encounter a problem that's not covered in the notes. I can't guarantee that I'll be able to give a good answer, but I'll try.

I accept cash (US dollars please), money orders, personal checks and Paypal (my Paypal ID is the same as my email address). The easiest way to order is to just click that Paypal button thing above this paragraph. If you prefer a different method of payment, please email me at and we can work it out.

ONE LAST QUESTION: Now that you're selling this collection, are you still going to keep posting and emailing sketches and notes for free to anyone who asks for them?

Well, dumb as it may sound, yes. Please don't ask me to email you the whole collection, though. That's cheating. :)=
