10 outputs 4 inputs connected together with patch gloves

uncertainty sauce

I haven't explained this well at all.  There is a little pot that has a copper pad on the base that is divided into 4, there is a non-conductive divide down the middle.  If you put resistors in one half and capacitors in the other then jiggle the pot you will get random varying resistances and capacitances between the pads of each pair.  These could be used to make freaky filters.  The speaker can jiggle the pot and make a nice shakey sound.

compander bear

A typical relaxation saw VCO. 
The first 4069 inverter just buffers the saw and drives an LED
On the 2nd inverter the center tap pot slides the LDR response across the input resistor, through center then across the feedback resistor.  So should this work as a compander yeah?

funny octave pattern thing

simple implementation of an idea for a funny old oscillator.  Modifications can easily be made by sending 'C' either high or low for acceleration or deceleration. This transverses 5 octave, can easily be modified to go through 3 or 2 octaves too.

Modular lunetta...

straight up g's just use 1 resistor for loads of LEDs.  yeahhhhh

new old mr grassi PCBs

Get down to wetherspoons for the new beer'n'burger'n'old Mr Grassi PCB deal. One is for surface mount styles and the other is for through hole (hence them being mirror images) (designed by Peter Blasser (ciat lonbarde) not me)
