Digital photo frame

Many years ago (circa 2005) I wanted a way of viewing all our digital photos so I came up with an idea of a digital photo frame. A laptop on the wall.

Donor iBook

The PSU was from an old printer and was rated for 30V 0.4A. I needed 21V so after inspecting the secondary feedback I found it was driven by a zener which I changed our with a 15v and 5.2v in series which gave me 20.2v output- close enough.

Replacement zeners

Power is supplied by a 3.5mm ring-tip-sleeve plug with a RCA sized outer shield. On the genuine chargers there is a resistor from this to negative(my memory could be wrong on that one) to define the power supply capacity. I didn’t need it as I was not charging any batteries.

Plug made for iBook. The housing is from a RCA plug as I did have the intention of making the full housing but it didn’t come to fruition.

The cable to the laptop I made out of a scrap piece of solid core CAT5 cable with 2 pairs for data and the other 2 for power. I figured I would try to only have 1 cable going up the wall to try to make it look a bit nicer.

I got the 1999/2000 model clamshell iBook from a Mac repair shop in 2 pieces so thus different colour shells. I made up a pair of brackets to allow the screen to lay flat against the base open and luckily the screen cables were long enough once taken out of their routing channels to make it the extra distance.

High-tech aluminum bar that was purchased originally for another project to make a step up transformer to power a 20kW car audio amplifier to enter into sound off competitions- a story for another post.

I removed the modem to try to reduce the power consumption and as it would not be needed. I made up a aluminum plate with some solid core CAT5 wires attached to take up the strain as the spot it was attached was not structural.

The dodgy wall mount bracket and screen attached to base with awesome brackets.

This is a post in progress so the next information may not be coherent and just notes for myself to finish off
