That new Raspberry Pi® Model B+ computer you just got has a row of 2x20 pin headers soldered on - those are the GPIO (general purpose input/output) pins and for those of us who like to hack electronics they are where the real fun is. By programming the Pi, you can twiddle those pins high or low, send and receive I2C and SPI data, and access the 3V and 5V power rails. This cable is not compatible with the Raspberry Pi Model B or Model A! If you want to bridge those contacts out onto another PCB, you'll want this cable! It's 6" long and has 40 socket & wire sets. Pin #1 is marked with a white wire.

It has way more resolution than a black and white 128x64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.

Z-axis tape is made by 3M, and is used to bond two conductive surfaces together and allow a small (we'd say keep it under 100mA) current to flow through the tape. But here's the cool part: its only conductive across the thickness of the tape itself, not along the length or width.

There are 32 RGB LEDs per meter, and you can control each LED individually! Yes, that's right, this is the digitally-addressable type of LED strip. You can set the color of each LED's red, green and blue component with 7-bit PWM precision (so 21-bit color per pixel). The LEDs are controlled by shift-registers that are chained up down the strip so you can shorten or lengthen the strip.

You have some electrons over here, and you want them over there but you don't want the electrons from over there to be able to come over here? That's what a diode is for, these are directional current valves and have the benefit of being waaay smaller than vacuum tubes.

Getting touchy performance with your screen's touch screen? Resistive touch screens are incredibly popular as overlays to TFT and LCD displays. If you want to connect one to a computer you need something to handle the analog to digital conversion. Most converters we've found are not very easy to use, and are 'fixed' - making them difficult to calibrate.

Connect this to that without soldering using these handy mini alligator clip test leads. 5" overall cables with alligator clip on each end, color coded. You get 12 pieces in 6 colors. Strong and grippy, these always come in handy! We often use these in conjunction with a multimeter so we don't have to hold the probes in place.

Designed specifically for wearables, these updated Flora NeoPixels have ultra-cool technology: these ultra-bright LEDs have a constant-current driver cooked right into the LED package! The pixels are chainable - so you only need 1 pin/wire to control as many LEDs as you like. They're easy to sew, and the chainable design means no crossed threads.

This is the easiest way possible to add small, bright RGB pixels to your project. We took the same technology from our Flora NeoPixels and made them breadboard friendly, with two rows of 3 x 0.1" spaced header on each side for easy soldering, chaining and breadboarding. These ultra-bright LEDs have a constant-current driver cooked right into the LED package!

These are half the width of classic 6mm tactile switches so they line up better on a breadboard, just plug them into every-other row. These work best in a PCB but can be used on a solderless breadboard. The two pins are normally open (disconnected) and when the button is pressed they are momentarily closed.

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.
