So as most Angel owners know, the Sensi pad is quite easy to damage or it just stops responding like it should.
To replace the Sensi pad is quite pricey, 40 dollars plus shipping and tax. depends on where you live. Im from South Africa and shipping is not cheap and takes a long time.
So whether you choose to use my idea temporarily waiting for your origonal ordered Sensi or completely replace the original Sensi is up to you.
Even though this exercise is really simple, things can go wrong and I will not be held responsible for damages to your marker.
SO lets start
1.)sharp stanley knife
2.)12mm piezoelectric plate like this
. these are available from any electronic components dealer. should cost a couple cents
buy a decent eraser, I used a cheap one and it was to brittle and kept breaking
Open the left grip, unplug all the connections to the opto board and remove the trigger frame. DONT loose the Sensi pin! remove the Sensi pad.
Cut the eraser with the stanley knife as showen below. the final product of the eraser should resemble the shape of the Sensi pad so that it fits snug into its position.
I cut the eraser slightly thicker so that it will get compressed and held firmly in place when the trigger frame is tightened on. As shown here:
Cut the wires off your broken Sensi pad. Solder the wires onto the piezoelectric plate as showen in the following pic. I just used some 0.25mm wire as my Sensi pad is not broken. dont put to much solder as this will stiffen the plate and make it less sensitive. there is no polarity.
place the piezoelectric plate into the eraser as showen.
place the your new sensi pad into the trigger frame. Route the wires clear from the screw and potential pinching areas.
put the Sensi pin back in and screw the trigger frame back on. make sure the Sensi pin is free to move and is lined up with the piezoelectric plate. also make sure you are not pinching any wires.
Success! Run the Sensi test and watch the green and red light glow!
