Wire Strippers		For stripping wire.
Punch		This is some sample text. This is also some sample text. I am a big fan of sample text. This is more sample text. This is even more sample text. I am a really big fan of sample text. This is the same sample text. This is more of the same sample text. I am a big fan of this sample text.
Soldering Iron		A hand tool which heats metal solder in order to join two components. Soldering is most commonly used to join electrical components in a circuit. There are two soldering kits for use at the electronics station in the center of the Maker Hub, and there are also several available for checkout in the Tool Room. For your safety, please always place the soldering iron in its holder when not in use. Always use a fume extractor to protect yourself from harmful fumes. Soldering kits also come with a tackle box containing useful tools for soldering, such as wire crimpers. Please make sure all contents of this box are returned when you finish using a soldering kit.
Analog Discovery 2		A USB oscilloscope, logic analyzer, and multi-function instrument that allows users to measure, visualize, generate, record, and control mixed-signal circuits of all kinds.
Fluke Thermal Imager		A thermal Camera. Very Expensive.
Solder Sucker		For sucking solder.
Tip Tinner		Lead-free tip tinner for soldering.
Solder Wicks		For soldering.
AC/DC Current Clamp		A current clamp is a device that measures electric current flowing through a wire, cable, busbar, or other conductor.
A.C. Clampmeter		This instrument can be clamped over a wire to measure the current flowing through it.
Cordless Drill		You can use a cordless drill driver to drill or bore holes, drive screws, assemble furniture, and woodworking.
Fume Extractor		A device which uses a fan to collect and filter harmful fumes. Always use one of these when soldering for your protection.
Cordless 1/2" Impact Driver and sockets		The impact Driver is specially designed for tightening and loosening various hex-head bolts, nuts, and lag screws. It employs both rotational force (torque) and short-burst concussive blows (impacts) to deliver an unparalleled amount of power.
Helping Hands		An extra set of hands to hold things while soldering.
PCB Tweezers		Tweezers for PCBs.
Mirror		An extendable mirror for viewing hard-to-see places.
Type K Thermometer		A thermocouple for measuring temperatures between -50C and 1300C.
BTMN Board		ARM training board used in ENGE320. Coupled with the Arduino Zero. Shield includes an AMOLED display, joystick, DPAD, RGB LED's, accelerometer, SD Card slot, and a piezo buzzer.
Multimeter		A multimeter is a measuring instrument that can measure multiple electrical properties. A typical multimeter can measure voltage, resistance, and current, in which case can be used as a voltmeter, ammeter, and ohmmeter. Some feature the measurement of additional properties such as temperature and capacitance.
Flux Pen		For soldering.
LED Worklight		A really bright light for illuminating an area.
Digital Tachometer		This is an instrument that is used to measure revolutions per minute or RPM. This is a non contact device that uses light and a reflector. This device can be used to measure the RPM of a motor shaft.
GoPro Camera		For Going Pro. Takes Video and Pictures. Can be used with the GoPro Accessories in the GoPro accessory kit.
Torque Wrench		A torque wrench is a tool used to apply a specific torque to a fastener such as a nut, bolt, or lag screw.
Logic Analyzer		Used to monitor and debug various digital signals and communication busses.
Arduino Uno		Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller. It is a Single circuit board that can be programmed and comprises of 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header and a reset button.
Helium Balloon Inflator		This is connected to a helium bottle and allows the user to fill a helium balloon.
Digilent Nexys 2		A powerful digital system design platform built around a Xilinx Spartan-3E FPGA.
Battery Terminal Cleaner		A wire brush designed to remove corrosion and contaminants from the terminals of a car battery.
Socket Wrench Set		A socket wrench is a type of spanner that uses a closed socket format, rather than a typical open wrench/spanner to turn a fastener, typically in the form of a nut or bolt. This set comes with an assortment of socket sizes.
Pressure Gauges		For measuring pressure.
Laser Thermometers		Handheld device that can display temperature readout on it after scanning portions of an object or area with the built-in laser. They tend to be inaccurate when measuring shiny objects, putting some non-reflective tape on the object can help give a better measurement.
Flux		For soldering.
Cordless 3/8" Impact and Bit Set		The impact Driver is specially designed for tightening and loosening various hex-head bolts, nuts, and lag screws. It employs both rotational force (torque) and short-burst concussive blows (impacts) to deliver an unparalleled amount of power.
Electronic Scale		Device to measure weight or mass.
Handheld Multimeter		An instrument for conducting measurements on a circuit. They can measure DC voltage, AC RMS Voltage, current, resistance, and more. Multimeters are essential tools for testing or troubleshooting a circuit.
