We love non-standard conductive materials here at Adafruit, and now we have a metal-based conductive paint for your crafting needs. This silver/tin/copper based conductive paint is usually used to repair flex circuits or maybe fill in gaps in EMF shielding. But you can use it on paper, plastic, fabric, etc. to create a low-resistance conductive connection.
The Chipquik Conductive Paint 5cc Syringe provides low resistance, metal-based conductive paint in 5g syringe with a plunger & two tips. It can be applied by dispensing, paint brush, or with stencil and squeegee.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
