I got a HP 7475A plotter cheep on ebay :)

at first I thought it was broken…

This was the windows test page lol! Looks like the printer is on LSD

Took a bit to figure it out

Then VICTORY!!

Key is the plotter cant plot faster then the data input after 2400 baud speeds and the buffer over flows and starts to overwrite the memory in the plotter

I hacked one of the pens that came with the plotter with the insides of a sharpie then started my attempt to plot boards :)

SUCCESS!! this is a version of my i2c fram breakout board :). I left it in the acid bath too long so the copper was very thin.

I finally got the parts I needed to build my Lilly Pad Arduino :)

Used some uber soldering skill to get the crystal attached :) you can barely see the caps it is attached to :-D

Im mad!! I want to buy stuff with paypal and i keep getting this stupid “You have hit a speed bump” error!

Tried to contact support and….

Im trying to call them by phone and now i get a error 500 lol

based on the FM24C16A chipFM24C16Ads_r3.1.pdf

added a small switch to enable / disable write protect

there is a solder jumper that can be removed to disable the switch :)

Can be plugged right into an arduino

Made a little breakout board for a 2 bit Fram state saver chip
