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.

LED Displays
A big grab bag of LED display tiles. Assorted colors - red, green, amber - and displays. Small are 1" x 2" and smaller; 3-9 volts; and include seven-segment numeric, dot matrix, and alphanumeric. Sorry, we can't tell you what size or display you'll get, but Small has at least (4) different. Think of it as a surprise present from Uncle Barry. Hook 'em up and find out what he gave you!

Mood Sheet
See psychedelic patterns the safe way! Press your hand on this 6" x 6" sheet of liquid crystal and leave a print of swirling colors that, like the mood ring of yore, you can use as a sign of your mood. The pattern will blend and fade in seconds as the crystals react to temperature. Tiny liquid crystals inside the film-like material react to heat by changing colors. As science, it demonstrates the way liquid crystal displays work. And you can cut it into pieces to incorporate into a science project. Or just leave it out for guests to play with when the party turns boring.

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.

LCDs
These liquid crystal displays are raring to go. As soon as we can get Mary Ann to stop playing with them we'll pick out (5) assorted displays for you. (She keeps zapping them with static electricity to see what pops up. Mary Ann is easily amused.) Sizes range from 1-3/16" x 2" to a few as large as 5" x 10". They're unused. Some have pin leads, some have traces right on the wafer. Either way, they're a terrific bargain.

Portable Oscilloscope
The Velleman HPS10 Personal Scope isn't some graphical multimeter -- it's the complete, portable, affordable oscilloscope you've been waiting for! The 10MHz oscilloscope has an analog bandwidth of up to 2mhz. It has 5mV to 20V/div sensitivity in 12 steps, and a 200ns to 1 hour/div time base in 32 steps, full automatic setup, and 5 different trigger modes. It measures dBm, dBV, DC and rms, has signal markers for Volt and Time, and 2 memories to store signals. It has an X and Y position shift signal, DVM readout with x10 option, and audio power calculation (rms and peak). Easy to use and, with a high-contrast LCD display (128 x 64 pixels), easy to read. Accurate enough for professional use on automotive and audio equipment, digital signals and various types of sensors, but priced low enough for educational and hobby applications. Requires (5) "AA" batteries or a 9V adapter (not included).
