full board shematics

[philteta]

Do you have a full board shematics ?
Can you precise what you call Vbias on you shematics ?

Best regards

Phil

Hi Phil, It's been a long time since I looked at this project. Here are some slides, which might give more information: https://docs.google.com/presentation/d/1eyxLd1PImkjojZzFUVALYp3uv3yM3Tf5eH8dU_bVEe4/edit?usp=sharing Vbias is the bias voltage. Here is more information about that: https://ocw.mit.edu/courses/media-arts-and-sciences/mas-836-sensor-technologies-for-interactive-environments-spring-2011/readings/MITMAS_836S11_read02_bias.pdf Hope this helps!

Phil, did you get this circuit working? I got a bunch of what I think are the right components and am about to try this out. Thanks!

Not yet,if you make this wonderfull stuff working and if you are ok , please share your shematics :-)After confinement, I will try with Vbias connected to the GND
At this time, I haven't acces to my lab...

I got it working with a voltage divider as shown in the Vbias doc linked above. I have a working circuit on a prototyping board and now a circuit board for the 8x circuits in production to be shipped to me soon. Happy to share the schematic now and the board files if/when it’s working correctly.

Cool thank you :-)

@mshaub, Great to hear you got it working! Would be great if you can share some photos of the table when it's in action!

@mshaub I'm reading this thread but I'm still having trouble building my circuit, and I don't think I have everything there that is necessary. Could you provide photos of your working circuit? Thanks!
