Quad Power
The Quad XP-581 from Elenco provides four separate, fully regulated power supplies. Three are fixed and yield +5 VDC at 3 amps, -12 VDC at 1 amp, or +12 VDC at 1 amp. The fourth supply is variable, producing 2.5 to 20 volts of DC output at up to 2 amps. Line and output voltages are regulated to within 0.05 volts, and the supply is linear. All four supplies are shortproof as well. A current foldback circuit in each supply collapses the field in the event of a short, a current surge from the line, or an excessive current demand. Thus, both the Quad XP-580 and the equipment it's driving are normally protected from inadvertent errors or power company problems. Elenco built the supply as only Elenco will. The handsome, hooded metal case, - measuring 3-1/4" x 8-1/4" x 9-1/4" and weighing nine pounds - has a 3-wire grounded power cord for 115 VAC operation, panel meters for both current and voltage, and standard jacks for accessing the four regulated supplies. A two-year limited warranty and schematic is also included.

Azure Blue
The sky and this tough acid resistant, flame retardant .035" thick vinyl. I always forget how many decimal places to shift for mils - just trust me, this is heavy duty. It has a screen printable gloss finish and is 39-1/2" x 24". Quick experiments here indicate that a Sharpie(tm) will "take" on this stuff, but most markers don't. It's just longing to be cut up into place mats, high chair mats, stencils, art mats, or your craft project.

No More Cooked Kids
Cranked-up water heaters mean clean laundry, but risky showers. The 1-1/2" wide x 2" long Scald Guard has a standard 3/4" thread, and screws in between your shower head and water pipe. You decide what "too hot" is, and the adjustable valve reduces the water flow to a trickle when it hits that temperature. Make life safer, especially for the very young and the very old.

A Working Wonder
If we had a category just for customers who lust after Jules Verne inventions and elegant gadgetry, this would be in it. The wonderful brass sundial, a reproduction of an antique, is approx 3" dia x 11/16" thick overall, and actually works! A latitudinal gauge lets you tilt the engraved dial to the correct angle for your location, and a bubble and three leveling feet allow the 1-1/2" dia lock-down compass to point in the precise direction. And if you never took it out into the sunshine, you'd still love it for the look and logic of it.
