This smaller solenoid is designed to work directly with 5V which makes it a great match for embedded projects.
This is a carbon fiber safety cover protects a toggle switch from accidentally being turned on.
Features: 1.97" square x 0.21" thick (50 x 50 x 5.3mm). 0.4 watt max operation at 8 ohms. Frequency: 500Hz - 8kHz. 10% distortion at 2kHz. Stainless steel diaphragm. Solder type connections.
This 0.5W, 8Ohm speaker is only 40mm in diameter and just over 4mm thick. If you want to get some sound out of your project but have a tight space budget, this is a good way to do it.
This is a 12-step rotary encoder with a nice 'clicking' feel. It's breadboard friendly, and has a pretty handy select switch (by pushing in on the knob). The encoder is different from a potentiometer in that an encoder has full rotation without limits.
This is a small 12mm round speaker that operates around the audible 2kHz range. You can use these speakers to create simple music or user interfaces.
