30V, 10A DC Power Supply > Adjustable DC Power Supplies are easy to come by, but high current, adjustable power supplies are another matter. They are typically either fairly expensive, or difficult to find. Our DC Power Supply is ideal for...... more info

Low Voltage Cable Set Ideal for use with our 30 volt power supply - or any power supply (up to 600 volts) with 'banana plug' style jacks. Connect your Power Supply to your project without the hassle of building your own cables. Standard...... more info

  Necessary for any work with high voltage potentials, we have 2 sets of power cables available. One rated at 15KV and the other rated for 30KV. Ideal for use with our High Voltage Power Supply - or any higher voltage power supply with...... more info

Dumet Wire > Attempting to seal ordinary wire in glass will always fail due to the vastly different expansion ratios for glass and metal. Dumet wire on the other hand, has the same expansion ratio as glass - and is what is used for making light...... more info

Peltier Thermoelectric Cooling Chip   Amazing devices, one side of these Peltier Chips becomes absolutely freezing cold and the other very hot when power is applied - make a miniature refrigerator with no moving parts - and no compressor! ...... more info

Ultraviolet LEDs UV LEDs - solid-state 'blacklights. UV LEDs will make fluorescent paints & 'invisible' inks glow brightly. The UV light from these devices will rapidly charge up glow-in-the-dark products much faster than normal bright light. The.... more info
