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.

Chemical Overboots

Large, black rubber boots designed to fit over your normal footwear for protection from chemicals, solvents and other hazards. The design is such that we like them better for warmth and winter traction. But we're ahead of ourselves. They are large enough to fit comfortably over most any shoe or boot. The heavy sole extends forward and back and to both sides, and there are four large, molded-in eyelets. Laces or thongs are then used to cinch the sides firmly around the foot and to take up the slack. How about using the molded cleat bottom for ice fishing traction? Or keeping a pair in the trunk for slogging around in the slush changing tires and the like?? Or going to the costume ball as a survivor?? Made about (8) years ago for Uncle Sam.

Luminous Paint

This water–reducible acrylic–based paint sticks to most surfaces and glows in the dark after only a brief exposure to bright ambient light. We have a 2 oz bottle of yellow/green that will glow for up to 20 hours. This works great for Halloween costumes and hobby applications, and glows like crazy under blacklight. And without a single radionuclide! Amazing!

Soil Test Kits

The budding home scientist and horticulturist will both delight in the ease with which this self contained soil test kit brings discovery. The kit measures not only ph., but also Nitrogen, Phosphate and Potash content and contains material for 40 tests. Since these are the essential ingredients affecting plant nutrition, we see a science project in the making: experimental plant growth in soils with different amounts of acidity and/or nutrients. From Luster Leaf(tm), the kit is entirely self contained and includes complete instructions for use and explanations. Be careful, please, the kit does have chemicals and should not be used by young children without supervision.

Shrink Plastic

Incredible stuff!! And even better than those dinky cutouts you used to make! Our each is a pack of (8) 8" x 10-1/2" shrinking plastic sheets that start clear and stay clear. Draw a design, write a message, create a sign, whatever. Cut it out, bake it in a 350° oven for about 3 minutes, and it shrinks to 45% of its original size. Problem with certain pencils and markers on the slick sheets? Try a light sanding (320-400 grit) before writing on it. (The surface will be more opaque.) What a fun way to make small errors become insignificant!

Rotary Tool Set

Not every well-made rotary tool is a big-D. We consider this one not only a good-quality tool, but an excellent buy. The fitted plastic carrying case 12" x 8-1/2" x 3-1/2" contains not only the 120VAC-powered 8,000-30,000 rpm mini grinder, but a stand with a C-clamp to mount it on a bench or table, a 3-ft extension shaft, and a good assortment of bits, grinding stones, cut-off wheels, etc, including collets to fit 1/8" and 1/16" bits. The telescoping stand extends from 10" to almost 22" and holds the tool above your work, while you grind, sand, cut, etc., with the tip of the convenient, easy-to-grip, flexible extension. A nice package, and a very nice gift for yourself, or for anyone who enjoys working with hobby tools.
