Proximity sensor boards

Hi Jarno
Do you still have some proximity sensor boards?
Cheers Sascha

I finally got around to building my first one last night and . . . .

I burned up R7 and R8. I am CERTAIN the power is keyed the right way round, even measured the voltage. So I'm guessing I put the TL072 down backwards and the low-Ohm resistors protected it? Or at least tried to? Does that seem reasonable? I'll build up my second one and see how that goes . . . .

Edit to confirm: I put the TL072 down the wrong way 'round despite clear instructions for "chamfered side is towards the 10r resistor." Not sure how I botched that.

One more edit to say the sacrificial protection resistors did their jobs - did my first hot-air rework and flipped the chip, replaced the 10R's and it was good to go. This'll be fun.
Don't think I saw this reply earlier (really should subscribe to this thread), but that's good news! And you actually re-used the chip, kudos!
I usually use the dremel to get rid of wayward IC's and replace them with shiny new ones :D

2.4SINK Wireless Eurorack Interface

Post by instruments of things » Fri May 17, 2019 4:04 am

This may be interesting for you:


It's a wireless sensor interface with 16 multimode outputs supporting OSC and Bluetooth MIDI.
Bundles including motion sensors with 9 degress of freedom sensor fusion are available as well (up to 7 motion sensors via Bluetooth LE simultaneously).
Also suitable for low latency applications (e.g. triggering percussion sounds).

The kickstarter project is currently live (21 days left!) and got great reactions at this year's Superbooth. Check it out for some demo videos and more information.

You could use a Kinect with simpleKinect and send the position in space via OSC:)
