24VDC 5A regulated, floor-mounted power supply from Megmeet. Output is via a 4-1/2-foot cord with a 4-pin KPPX connector, which looks to us like a mini-DIN plug. Has overvoltage protection, current-limiting and will need an IEC computer-style input cord. Switching type with the pinout marked on the 6-1/4” x 2-1/2” x 1-3/8” housing.
The book of illusory optics. This anonymous book of visual puzzles and optical illusions has a staggering (350) black and white entries, both ancient and modern. Spiral-bound and equally at home in the physics class and bathroom, which you can’t say about everybody.
These French military field suspenders are olive drab canvas and are marked “PARIS 1978” inside the yoke. (And the yokes on you.) In an H-shape, they have 1-7/8” wide x 10-3/4” long straps on the front, narrowing to 3/4” wide adjustable straps for another 6-1/2” with clips on the end. The back has a pair of 7/8” wide x 27” long straps with hook-and-loop fabric on the back to close on itself. Front straps have a D-ring each for French grenades that we don’t carry.
These clear plastic (PET) jars are small peanut-butter jar sized. Measure 3-5/8” tall x approx 3” dia with straight sides, and hold about 10 oz. which is roughly the same size as an 8-year old's marble collection, double the amount of coins in your car's cup holder and the ideal space to hold 17 fireflies before releasing them back into the night. Come with a gasketed red plastic screw cap.
Military style and shape, this dark-olive drab, 1-quart canteen is painted aluminum with a brown plastic screw cap on a cord keeper. The whole thing hangs in a web of olive drab canvas straps on an adjustable 20” neck strap. Measures 7” tall x 5-1/2” x 3-1/4” with a 1” dia mouth and holds a bit over one quart.
Everything big is little now, including this 12VDC muffin fan from Delta. Draws 570mA, spins approx 14K rpm and pushes about 17cfm. Measures 1-1/2" square x 1-3/32" thick with 1/8" mounting holes at the corners. (wire red to +12V, black to ground, blue to freq and yellow probably a thermistor.) Computer cooler or perfect for a hot gerbil habitat. Part #FFBO3812HHN.
Leave your lights on much? Or maybe you live in a place like we do, where January means weather so cold the squirrels explode in the trees. Either way, you're a bunch better off with the 1000 QuickCable 12-Volt Heavy Duty Rescue™ Booster. About the size of a construction worker's lunch box (15" x 14" x 9" and weighs 20 lbs), it packs a lot of punch—1000 peak amps and 500 amps of cold-cranking power. Includes: illuminated clamps; underhood and emergency flasher lights; 55” cables for reaching over fenders; a reverse-polarity circuit that eliminates reverse hookup connections; 12-volt accessory port; easy plug-in AC recharging; charging and full-charge lights; storage compartment for tools and gloves. Beats standing around on the side of road watching for a truck on the horizon, we think. So easy an English major can use it.
