For the butt plug I used the stainless stell encabsulated version of the temerature sensor DS18B20. Sold for example here: https://www.az-delivery.de/products/2xd ... asserdichtthatthat21 wrote:For the butt plug did you use an inflatable plug and just remove the inflater bulb and hose and put the thermal probe inside it that way?
On the dildo, it looks like it was a normal suction cup base type, but looks like you insert a tube of some sort to install the light sensors? If so, how did you go about getting that inserted?
I pricked it simply into the soft infill of the butt plug.
The insertion of the photo transistors into the dildo was a bit more challenging. I pricked a hole into the dildo using a metal tent peg. Then I slid a transaperent plastic hose over the tent peg and shoved it into the hole. The hose remains in the dildo. With the outer diameter of ~9mm and inner diameter of ~7mm it allows the insertion of the photo transistors (diameter ~5mm plus cables). When I'm ready with fine tuning of the photo transistors, I will fix them with cast resin.
