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.

Does Sister Spark a Memory?
WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
Say your prayers, Catholic school survivors! You've met your match with Nunula. Her size and gait are remarkably similar to those of Sparkdino, and she spews similar (though much more holy) sparks from her gaping mouth. She's decked out in the church's finest: black robe and hood with a white wimple, a cross around her neck, bible in one hand, and a ruler (shudder!) in the other. Now stop playing and get back to your lessons!

Chinex?
Rejoice, we have finally found a source of reasonably priced borosilicate lab glassware. This is the kind of glass in the trade marked Pyrex(tm) and Kimax(tm) labware. The stuff you can put right over the flame of the Bunsen burner, or directly onto the hot plate. This stuff is imported from China, and is considered student grade, which is good enough for anything but the most exotic applications. We have beakers, test tubes, graduated cylinders and flasks. Compare the prices below and you will see that they are around half the U.S. equivalent. Call us for larger quantity prices.

Adapting to AC-Surplus Transformations
There is an entire class of transformers that surplus dealers call "AC Adapters." What we really mean is transformers that plug directly into the wall (primary voltage 110 VAC), and via a cord and/or plug provide various levels of output current at variou s voltages. It is a rare buyer of surplus that gets the plug configuration he/she wants, and many get snipped off (plugs that is). They are handy power supplies, battery charging units, substitutes for batteries in toys and games, or for providing safe il lumination to models and displays. Be sure to note whether the output is AC or DC (Direct Current, like a battery) and whether it can provide enough current for your application. Unless otherwise noted, all are suitable for indoor use only. Stick with us and you'll get the hang of adapting to AC...and at much lower prices than your friendly appliance/game/computer/calculator shop asks. Unless otherwise noted, all adapters are for 115 volt AC primaries, and all have about 6 ft. cords. (MA=Milliamp) (A=Ampere) (VDC= Volts DC) (VAC= Volts AC).

Battery Holders
We have a number of battery holders, constantly changing in detail. They may be plastic, they may be metal. They all have either simple short wire leads or connection points. In all cases, they hold a number of batteries and connect them internally in series. The table shows the number and type of batteries held, the final voltage, material, lead type and price.

Break Your Own Geodes
WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
Pop one of these roughly 1-1/4" dia stones into the toe of a sock, smash it with a hammer, and be the first person ever to see your real-as-Nature-makes-it geode!! Ninety percent of them have the familiar beautiful white crystals inside. Formed by volcanic action, they are found all over the world, but ours are from Mexico. There is no way to tell from the outside if they have crystal centers, but we will send you two just to raise your odds, and we haven't had a dud yet in our stores!! Much much more fun and satisfaction than buying one already cracked.

Incredibubbles!
WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
We love these! You're going to love these! Your kids are going to love these! Hundreds of clear marble-sized bubbles can cover the floor, cling to the sides of furniture, land on your arm. They float enchantingly, rising on air currents you can't even feel. After a few seconds, the bubbles are hard enough to catch or stack. Some will still be perched in out-of-the-way spots a day later. Touchabubbles goop, thicker than the bubble-blowing liquid you're familiar with, comes in a 4" plastic test tube with a wand built into the cap, and a clip on the side so you can carry it in a shirt pocket. The goop is nontoxic, but it tastes really bad, and you probably won't want these landing on expensive tabletops, so kids under 8 should have adult help with them. They should be sharing the fun anyway!

Original Slinky(r)
WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
Does anyone need to be told what a Slinky(tm) toy is?? Okay, it is a very slack spring, 2-7/8" dia x 2-1/2" long, compressed. It will stretch out to about 5 or 6 feet long without deforming. That's the boring part. The interesting part is that it "follows" itself. Slosh it from hand to hand. Put in on the top step of stairs, flip the end down a step, and watch it walk down stairs, or down an incline. Believe us, no childhood (or adulthood) is complete without an original stainless steel Slinky(tm). It was hard for us to find it, but we are glad we did. You should be too.

Treat With Heat
Start with one naked wire or a number of them, and a piece of our clever tubing, and end up with nice, tightly covered wire. For the specific diameters below, our each is a package of (10) 12" pieces of heat-shrink tubing. For an assortment of sizes, our each is a dozen pieces of 4" long tubing. You'll get (4) pieces each in 1/8", 1/4" and 1/2" diameters. All sizes are black. All will shrink to trim diameters half their current size when heated to 125°C/257°F. If only it worked on waistlines.
