Infrared LEDs are used for remote controls (they're the little LED in the part you point at your TV) and 'night-vision' cameras, and these little ...

Do the CNC electric-slide! To the left, now to the right. Now you have no excuse for not building that CNC robot. This is a 'supported style' 15mm ...

When your little robot needs someone to lean on, it can lean on this support wheel. Perfect for use with 2-wheeled robots that need a third-point o...

Make your robot or CNC move on rails super fast with a linear bearing platform. The platform is 34mm x 30mm and has four holes tapped for M4 machi...

If you have an 8mm linear rail, you'll want to give it a bit of guidance and support to help it through the day. Sometimes a good word and a pat o...

For projects that need a rotary encoder but need to keep it single-sided or need to avoid interrupting traces or devices on the other side, here's...

This adapter board is designed to make it easier to use ARM dev boards that use slimmer 2x5 (0.05"/1.27mm pitch) SWD cables for programming. It's h...

This 1.27mm pitch, 2x5 male SMT Box Header is the same one used on our SWD Cable Breakout Board . The header alone is great if you want to incorpor...

Back in my day, if you wanted to make a mechanical keyboard, you had to solder in expensive key switches onto your PCB - and woe to the person who...

This switched JST connector is the best way to quickly prototype with our LiPoly batteries. We paired a genuine JST connector with a slide switch t...

I know you just did a double-take when looking at this power supply, what's up with the two cables? Normally you have a switching power supply that...

This Swivel-Head Pan-Tilt (PTZ) Shoe Mount Adapter allows you to attach something with standard 1/4" machine screw mount to a camera's shoe mount,...

Create your very own Arduino-controlled 3-axis CNC machine with the gShield. The gShield for Arduino (formerly known as grblShield) is a complete h...

These go great with our silicone tubing for air pumps and valves - great for making adapters or splitters. The three ports have an outer diameter o...

This T-Slot Photo Interrupter is a simple plastic sensor with two elements - an IR LED and an IR photo-transistor, situated across a U-shaped gap. ...

Trends come and go, but preparedness is always in fashion! Have you ever been in a situation where you desperately needed a screwdriver right away...

Push once to turn one side on, push again to turn the other side on! It's basically a push-button toggle switch that connects and disconnects the m...

Little clicky switches are standard input "buttons" on electronic projects. These work best in a PCB but can be used on a solderless breadboard as ...

Squeeze once to turn on, squeeze again to turn off! This clicky switch makes a great power switch or mode toggler. We like this switch because it's...

When designing your next PCB, if you're not sure what sort of tactile switches you can fit, or how they would look, this Tactile Switch Assortment ...

Medium-sized clicky momentary switches are standard input "buttons" on electronic projects. These work best in a PCB but can be used on a solderle...

Slim clicky momentary switches are standard input "buttons" on electronic projects. These are half the width of classic 6mm tactile switches so the...
