Here is my first "Manhattan Style" circuit, a 136 kHz series L-C tuned Clapp oscillator.

In my case where I want a nice sinewave with negligible frequency drift vs. temperature
the Clapp oscillator needs to be re-spelled with an "r" instead of an "l"

My friends know I'm mad, but that doesn't matter... they know that if they try to run away, they'll just know a sharp pain between the shoulder blades, and then nothing more.
Wait, I didn't just say that... *puts on sunglasses, gets out neuraliser*

An overhead projector is quite ingenious. It hadn't crossed my mind as a method. If I ever get an urge to draw on my wall, I will first try to destroy it by holding my head in a bucket of water, then if that fails I might well have to borrow a projector.

I normally use pencils ranging from 4H to about 2B or 3B. I find that the harder pencils are good for the line drawing, then I advance to a HB and B for the general shading and for the really dark areas, the 3B range.

And for some good news, the hosting I had my files on managed to recover (it's been on and off for months), so I'm finally recovering the digital versions of my earlier work. I'm going to rehost them reliably, and then link to a couple of them so you can see some of that too.

Also on my agenda, if all goes to plan, I'll be meeting up with a member of a spudgun forum in a week or two to do some stills photography of things being shot with air cannons. Not as cool as high speed videos, but pretty neat anyway.

meh, to work with the overhead projector was just a pain in the ass.. the pic was blurry and far away from what i expected, so i used it only for the significant lines and areas and then brought it back (projector was borrowed) a beamer would have been much better, but, shit happens. now im working with a few prints, thats all

i like that coffee steve. it reminds me on my coffee. mh shit, where are all the smileys gone?
mhh, cookies

I recognise that scope Sulaiman, hope you're getting some good use out of it! Did you ever find the fault?

steve - they look a bit like rear hubs... sort of.

I found this on the wall above my head when I woke up this morning. Such big ones are rare to see where I live, this one was over 5cm (2") big.
