Work like a watchmaker with this extremely steampunkish clip-on triple loupe. In brass-plated steel, it clips on the temple of a pair of glasses with the three 15/16” dia lenses (2X, 2.5X and 3X) on 1-1/2” long arms that swing in and out and are adjustable via set screws. The spring clip for the glasses opens to 5/16”. Working distance is short like all loupes, but you’ll look extremely cool.
This 3-6VDC motor operates optimally at 6VDC, draws 450mA no load, stalls at approx 2.4A and spins at about 13K rpm. Measures 2" long x 1-1/16" dia with a little 3/8" dia x 5/16" 12-tooth gear. Simple +/- leads are wired to a double jack that can easily be cut off or jumped. Leads are 14” long.
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.
This pre-filled PC board has (50) white LED chips on a board measuring 22" long x 1-1/2" wide at its widest, with clearly marked power in/thru jumpers at each end. You’ll need at least 24VDC at 300mA to fire it up. Max is 32VDC 525mA, and we don’t recommend staring directly at it when it’s in operation.
We’re semi-gaga over these lightly used Belgian Army Engineers’ bags because we don’t hardly ever get square bags. This one is 11-1/2” tall x 5-1/2” square (loaf of bread-sized) in heavy olive drab canvas. Top has leather-reinforced side panels and closes with a brass and leather tab/slot. Has a 4-foot adjustable strap with a lanyard clip, plus (3) C-rings on the back. Inside has (2) 8-1/2” deep side pockets.
This 12VDC tin-can stepper motor from the Nippon Pulse Motor Co. is a uni-polar 2-phase with 50 Ohm coils drawing 240mA per phase. Moves 48 steps/revolution with a 1/10 gear head at the output. Measures 1-5/8" dia x 1-1/2" on a 1-11/16" square mounting with 1/8" mounting holes. The offset flattened shaft is 1/2" long x 3/16" dia. Has (6) leads with a Molex connector. Part #PF42-48.
Our each is (200) light-duty cable ties in dark green, from Gardner Bender. You’ll get (100) each at 8” long x 1/8” and 4” long x 3/32” in a reusable tube that has a hole in the cap so you can peg it to your wall for storage. The color makes them ideal for the garden, or on floral displays and wreaths. Also make good handcuffs for miscreant geckos.
You need a dehumidistat to sense the relative humidity and turn on a fan or whatever dehumidifies you. This one is from Broan-NuTone and is rated for up to a 10A load at 120VAC and 5A at 240VAC but can be used with a low-voltage (24V or less) fan. Use the clearly marked, easy-to-use dial to set your humidity anywhere from 20 to 80 percent, with full on and off settings as well. Housing measures 4-1/2” x 2-3/4” x 1-1/2” with keyed 5/32” mounting holes. Comes with mounting hardware, Lo-V terminals and wiring instructions. Made in Canada by humid Canadians. Broan #DH100W.
Tuck this small roll of black duct tape in your glove box and drive away secure in the knowledge that you’ve got what it takes to repair a leaky hose under the hood at midnight in the rain. Measures 1-7/16” wide on a 1-1/2” core, and you’ll get (15) feet of tape, enough to fix a hose and stick a broken mirror back on the door. Dead-center in the you-don’t-know-you-need-it-until-you-need-it category.
