Micro Chuck
A really small guy who lives....Whoops! Wrong Chuck. This one is a drill or rotary tool chuck with a 1/8" shank and fits bit sizes #60-#80 to facilitate handling tools with truly small shanks. Very handy in the modeling and electronics worlds.

LEDs By The Dozen
Light emitting diodes. Solid state devices that provide the ubiquitous power and indicator lights on your electronic gadgetry. Unlike lamps, there are no filaments that glow. Rather, some two volts of DC power at a miniscule 10 to 20 milliamps of current get the chemistry excited, and they just plain emit. Emit is a good word, too, as they don't really cast light, but glow brightly. We have a nice assortment of 3 and 5 MM diameter sizes in red, green, orange, and yellow. The longer lead is always positive, the shorter always negative, and you always need a current limiting resistor (about 500 to 1,000 ohms for 5 to 9 volt DC sources) to keep the current in the 10-20 MA range. If that's Greek to you you're either going to blow a lot of LED's or learn to change incandescent indicator lamps ! !

Hand Blasters
WARNING: CHOKING HAZARD-This toy is or contains a small ball. Not for children under 3 yrs.
Instant annoyance for adults and fun for kids, 8 and over. A pair of balls 13/16" in diameter, one sickly green, one mottled rose. Never mind the color. Hold one in your hand, toss the other in the air and catch it with the hand holding the first one. When they hit, they emit a loud pop like the cap in a cap gun. Blasts safely over 200 times. Which should be enough to wear out both parent and child. Made in Taiwan.

Thermal Sensor
Heat switch that is normally open below 135° F and closes at higher temperature. Imagination is the limit here. We don't have formal electrical ratings but believe it can handle about 2 Amps @ 120 VAC. It can be used (perhaps with a relay) to trigger a fire alarm when mounted near a furnace, in a garage, or in an attic. How about using it to shut off electronics or motors when overheating occurs? Or to activate a fan for cooling? Use it to record how long the furnace is on to rate its efficiency. 5/8" dia x 3/8" sensor head with (2) 1/4" x 1-5/8" long fixed leads.

Child Unspoiler
Fiberglass rod, 3/16" dia. It is quite stiff, but flexible and we will give you a 10 ft length coiled. Nice yellow plastic coating. Since the world court has ruled out caning, you are going to have to come up with your own use for it.

Lazy Scott Bearings
Never seemed fair to nail the "lazy" tag so permanently on the "Susans" but that probably has no "bearing" on the issue. Also called turntable bearings, they are the square, flat ball bearing devices YOU bolt between two flat objects to achieve rotation. Like that spinning center section of a Chinese restaurant table. We had these in surplus once and they were quite popular. To our chagrin, we discovered they could be bought commercially for the same price. So we did. The 4" version is rated for a 300lb. load, the 6" for 500lbs., and the 12" (round) for 1000lbs.

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.
