My First PCB
Actually my second, I didn’t realise until I was about to start soldering that the first was mirrored and so couldn’t work with the surface mount chip. It’s a breakout board for a Honeywell HIH-6130 humidity and temperature sensor. I designed the layout in Eagle, printed it out and transfered some toner onto the copper board by pressing the print against it and heating with an iron. This didn’t transfer enough toner though so I went over it with a pen.

Pinhole "Lens"

Thought I should explain the pinhole pictures I’ve been uploading. A body cap with a hole drilled through it, a piece of foil taped over the hole and a tiny hole in the foil made with a pin. The small hole means not much light gets through so long exposures are required. In theory the depth of field should be huge but in practice nothing is in focus. More experimentation is needed.
