This Muscle Wire has 0.005" diameter and is one foot long piece of nickel-titanium alloy that can flex and contract when a specific amount of heat or current is applied to it. When the Muscle wire is in its martensitic form, it can be formed and bent into different shapes. However, when an electrica..
12V Solenoid lock has a slug with a slanted cut and a good mounting bracket. It's basically an electronic lock, designed for a basic cabinet, safe or door. When 9-12VDC is applied, the slug pulls in so it doesn't stick out and the door can be opened. It does not use any power in this state. It is ve..
Pololu 9V Step-Up Voltage Regulator U3V12F9 switching step-up (or boost) voltage regulator takes input voltage as low as 2.5 V and efficiently boosts to 9 V. The pins have a 0.1" spacing, making this board compatible with standard solderless breadboards and perfboards. They are switching regulators ..
3D printer Stepper Motor Flexible Coupling Coupler's are made of aluminum and have spiral cut that makes them slightly flexible so they can be fit to two shafts even if they are not perfectly co-linear and will help reduce binding effects.
Features of 3D printer Stepper Motor Flexible Coupling Coup..
A very powerful 5mW red laser point. Fun, but don’t point in anyone’s eyes. These units have the power wired in such a way that the unit turns on when power is applied. Increase the current flow and things starts to get very bright.
Cautions: Class III, avoid direct eye exposure to beams
5mW Laser..
Thermoelectric coolers (TEC or Peltier) create a temperature differential on each side. One side gets hot and the other side gets cool. Therefore, they can be used to either warm something up or cool something down, depending on which side you use.
This Peltier works very well as long as you remove..
Whenever you install a heatsink on a CPU or a video card, you always have to apply thermal paste. It is very crucial to the performance of the heatsink. You could get a very high-end heatsink, and without thermal paste, it will fail to work in the way it was designed too.
Thermal paste is a very hi..
Tiny RTC Module, for Arduino, contains a DS1307 real-time clock IC with a backup battery. It's one of the easiest to use RTCs out there, with Arduino and other libraries or simply use I2C commands to set and retreive the time and date. Includes a lithium coin cell battery which should be good for fo..
Description: This is a magnetic bead, suitable for RPM measurment with Hall Effect sensors. Install these beads on wheels and you could easily measure the RPM using Halleffect sensor interfaced with an Arduino. This bead makes it easy for you to build your own own sillometer and milemeter with Ardu..
Description: This little remote control would be handy for controlling a robot or other project from across the room. It has 21 buttons and a layout we thought was handy. It works fine with many of these commonly available IR receiver ICs. It would be a great aid in remote control projects such as t..
Description: Have you ever needed a cheap way to activate something from across the room? Infrared remotes are still the cheapest way to wirelessly control a device. This IR Remote Controller is small, very simple, and low-cost. With this remote we have an option of 21 different control buttons, whi..
This is an IC Test Clip for 8-pin small outline integrated circuits (SOIC). This test clip assures a secure connection to all chip leads on an 8-pin SMD SOIC and provides hands-free testing.
On this clip you will find two sets of gold plated contacts, upper contacts to attach wiring and lower conta..
The strap provides excellent grounding and hence safety to electronic components from damage due to static charges on personnel handling them.The elastic band is made of polyester and woven stainless steel/nickel fibers on interior surface. Each unit comes with a 2m coil grounding cord with a built-..
EL Inverters, if you are wanting to do anything with EL lighting you need one, period. This 3V EL Inverter is a special type that is intended to be used with a “chasing” EL wire. Unlike typical EL wires which only require a 2-pin connection, Chasing EL wire types require a 4-pin connection three for..
