UPdate 20140727 :- 4 legs = QuadPod

This is a Video for Gael and those searching fingertip sensor possibilities

First attempt at a sealed conductive compression cylinder..... this time hollowed out the 3M earplug..awaiting it to dry before i can test....."twiddles thumbs".

I wanted to make a blind encapsulated print but choose plan "B" instead... there is no harm in a tube of glue....(development glue)

Update 5 minutes later :- Nylon screws will be used...whoops

Inmoov starter finger gets its nails clipped with conductive foam insert

Early days to see how it performs :-

700 ohms resting

300 ohms compression, by manual test.....

Creating a custom keyboard (x,y) style (Top).... and capacitive style (bottom)....

They are encapsulated so waterproof_ish

Here is an ABS grid i coated with conductive ink and found that  "Burnishing" with a back of a spoon helps compact the layer and reduce its resistance dramatically.

This was just 15 mins cooking in the electroplating. (had to turn the current down (800ma @2.5V) as once the copper coat starts the resistance reduces YAY ....... I does form quite a resilient copper layer.

Appying a coat of Conductive ink to PLA allows you to Electroplate it with copper.

Its the first time for me and the results are exciting :-

The PLA needs a bit of sanding to roughen it up a bit so that the ink sticks better.

My Conductive Ink has arrived along with some 3M Ear-Plugs.....here is the Mix....

Offending Python Script......did i miss something........

Last Hurdle....Kinda......Multiple Servos now working from MRL >>> Propeller

Also created a universal Propeller Board...... one that is easy to fit things too.....

Bottom Left adjustable power Regulator ... for servos (5V-6V) underneath is a 3.3V regulator(Hidden)

Middle Left ... FTDI serial link

16 pin chip is an 8 Channel 12 bit ADC.
