EL-WIre Transparent

EL wire, or electroluminescent wire, is a flexible wire coated in phosphor. Apply the appropriate voltage and it lights up! It looks a lot like a thin flexible neon tube. The bendable wire runs alongside the phosphor wire, making the product nearly twice the thickness of the non-bendable variety. They come in a variety of colors and can be driven pretty easily with an inverter.

This particular wire glows with at transparent hue and is 3m (almost 10 feet) in length, approximately 5mm in diameter and is terminated with a simple JST-PH connector. This connector works directly with our SparkFun Original EL driver boards, the EL Escudo and the EL Sequencer.

Neopixel RGB LED-20 numbers

So, you want lots and lots of NeoPixels? And you want them for less? Not a problem! Here's a sheet of Flora NeoPixels fresh from the (reflow) oven. Cut them off as you need 'em and save a pretty penny while you're at it.

Each order comes with 20 pixels on a sheet.

What's a wearable project without LEDs? Our favorite part of the Flora platform is these tiny smart pixels. 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.

These pixels have full 24-bit color ability with PWM taken care of by the controller chip. Since the LED is so bright, you need less current/power to get the effects you want. The driver is constant current so it's OK if your battery power changes or fluctuates a little.

Each pixel draws as much as 60mA (all three RGB LEDs on for full brightness white). In theory, the Flora can drive up to 500 pixels at 30 FPS (it will run out of RAM after that). However, after about 10 pixels (or if the distance between pixels is more than an inch or two) the resistance of the thread can affect the power supply. For large quantities of pixels over 10, you may want to consider using stranded core wire or copper braid to provide a "power bus" for the pixels - the current draw will add up fast!

TMP 36 sensor

This is the same temperature sensor that is included in our SparkFun Inventor's Kit. The TMP36 is a low voltage, precision centigrade temperature sensor. It provides a voltage output that is linearly proportional to the Celsius temperature. It also doesn't require any external calibration to provide typical accuracies of ±1°C at +25°C and ±2°C over the −40°C to +125°C temperature range. We like it because it's so easy to use: Just give the device a ground and 2.7 to 5.5 VDC and read the voltage on the Vout pin. The output voltage can be converted to temperature easily using the scale factor of 10 mV/°C.

Load sensor-50Kg

This load sensor, sometimes called a strain gauge, is the same one found in digital bathroom scales (you know, the ones you use in January for your New Year's resolutions, and then forget about a month later). This sensor can measure up to about 110 pounds. Check the video below for a simple explanation on how these work and how to use them.

Lillypad Development board

The ProtoSnap LilyPad Development Board is designed to get you started in the world of e-textiles. Combining a LilyPad Simple Board with other LilyPad components like a buzzer, a vibration motor, an RGB LED, a button, a switch, five LEDs, a light sensor, and a temperature sensor, the ProtoSnap LilyPad Development Board lets you dive right into wearable electronics. When you’ve learned how to program the LilyPad Arduino Simple Board, break apart the components and explore the power of the LilyPad platform.

We've made some minor changes since the last revision that make it easier for us to build and easier for you to snap. We haven't changed anything about the way it works though, don't worry! This kit does not include a USB cable. You will need a USB mini-B for the FTDI basic, we offer it in 6ft red6ft black, and 2in black. Check below for an appropriate cable if you don't already have one.

MakerBot BotStep17 REV E

The BotStep17 plugs into the MightyBoard to control the stepper motors on your MakerBot Replicator 1, 2, and 2X desktop 3D printers.

These little boards can blow from time to time with smoke and a loud crack noise.

There are 4 on a single extruding Makerbot Replicator 1 or 2 (X-axis, Y-axis, Z-axis, E-axis [for the extruder]), and 5 on the Replicator 2X and Twin Replicator 1.

There may be no physical evidence of a blown bot step on the board. When blown they can fade a screen, cause lines through a screen, and affect motor movement.

Before testing or installing, take a picture of the motherboard to make sure you get the orientation correct when you reinstall. If you suspect one has blown it is easy to test:

  1. Remove them one by one and turn the machine back on. Do not replace them until the end as there could be more than one that is blown.
  2. When you get to the point that the machine starts up properly, begin replacing the bot steps one at a time to see which ones are blown.
  3. Replace any bad BotSteps with new ones

If it is affecting movement, but not the screen etc, try swapping the Z-axis with the one related to the bad movement. Usually the X-axis as it works the hardest. If the problem resolves in the X direction, for example, you know that bot step needed replacing.
