Fingerprint Sensor AS608 - A Beginner's Guide
One touch can replace keys. This project uses an optical fingerprint sensor to enroll users and then grant access with a quick scan.
read tutorial →Kiss those days of heat-shrink, melted jacketing and clumsily-arranged third-hand tools goodbye! Go 'cold splice' with these snap-able plastic splices for fast connections. Use with any 19-26 AWG solid core wire and slip them into the plastic splice so that they slide into the metal teeth. Then squeeze down with parallel-jaw or slip joint pliers - don't use needle-noses, they have too much angle and not enough force. We also like using our panavise to squeeze them down.
This is a three-way butt splice. Connect two or three 19-26 AWG solid-core wires by sliding them in and then squeezing all at once. It's an easy way to connect multiple wires without soldering.
The splices contain a little silicone jelly to keep the cold splice from oxidizing so they are a bit weatherproof. They are not waterproof.
Comes in a pack of 10 pieces! They're handy so keep some around in your drawer.
