SparkFun – Voltage Regulator – Adjustable

SparkFun COM-00527 Mk01

SparkFun COM-00527 Mk02

SparkFun: COM-00527

Description: This is the LM317TG voltage regulator, a three-terminal positive regulator with a 1.2V to 37V adjustable output voltage. This adjustable regulator provides a local regulation, internal current limiting, thermal shut-down control, and safe area protection for your project. Did we mention that this guy is easy to use? It only requires two external resistors to set the output voltage. Each one of these voltage regulators can output a max current of 1.5A.

Features:

  • Output Voltage: 1.2V – 37V Adjustable
  • Output Current: 1.5A
  • Thermal Overload Protection
  • Short Circuit Protection
  • Output Transistor Safe
  • Floating Operation for High Voltage Applications

SparkFun – Arduino Stackable Header Kit

SparkFun PRT-10007 Mk01

SparkFun PRT-10007 Mk02

SparkFun PRT-10007 Mk03

SparkFun: PRT-10007

Description: These headers are made to work with the Arduino Main Board, Arduino Pro, and the Arduino Mega. They are the perfect height for clearing the USB-B connector and great for stacking multiple shields. This kit includes 4 headers (2 8-pin and 2 6-pin), enough to connect a shield to an Arduino Main Board. These are the same headers we use in our tutorials and with our own shields.

SparkFun – JST Jumper 2 Wire Assembly

SparkFun PRT-09914 Mk01

SparkFun PRT-09914 Mk02

SparkFun PRT-09914 Mk03

SparkFun: PRT-09914

Description: This is a simple two wire cable. Great for jumping from board to board or just about anything else. There is a 2-pin JST connector on one end, bare cable on the opposite end. It also comes with the mating connector for the JST.

Dimensions: 6″ length

SparkFun – Female Headers

SparkFun PRT-00115 Mk01

SparkFun PRT-00115 Mk02

SparkFun PRT-00115 Mk03

SparkFun: PRT-00115

Description: Single row of 40-holes, female header. Can be cut to size with a pair of wire-cutters. Standard .1″ spacing. We use them extensively in the Olimex development boards. They mate very well with break away male headers.

Please Note: You will probably lose one pin with each cut.

Features:

  • Receptacle Style: Square
  • Number of Pins: 40
  • Pin Spacing: 0.1″ (2.54 mm)
  • Receptacle Depth: 6 mm

Steward-MacDonald – Orange Drop Caps

Steward-MacDonald 1281 Mk01

Steward-MacDonald 1281 Mk02

Steward-MacDonald 1281 Mk03

Steward-MacDonald 1281 Mk04

Steward-MacDonald: 1281

Upgrade to the quality caps used in Fender and Gibson guitars.

Made of durable high grade polyester, and favorites for vintage restorations or new builds.

Capacitors are energy-storage devices that filter the high frequencies. A cap lets the tone control roll off the treble response, progressively warming the tone. The higher the value, the more bass output from the tone control at its “zero” setting.

A cap wired to a potentiometer creates a standard tone control, as explained in this Article: How a tone control works.

100V. Sold individually.

  • .022uF 223K Humbucker Tone
