Don’t even try resisting, because you can’t. But this 10K-15K Ohm Photoresistor (aka Photocell, aka the thing that turns stuff on and off based on light levels) does nothing but resist. Sort of. It’s a light-dependent resistor that operates at 2K Ohm at 100 LX (that’s 3 feet from a 100W bulb), and 10K Ohm at 10 LX (12 feet from a 100W bulb). Rated for 100VDC, 35 mW power dissipation. Measures approx 5mm dia, and we’ll send you (5) of them. Made in Hong Kong.

Little is the operative word here. These surface-mount LEDs are perfect for hobby trains, dollhouses, even flashlights, anywhere you need tiny but bright lights. Color is white with a luminous intensity of 1000-1300 mcd (millicandelas), 2.8-3.4 volts, and a color temperature of 6500K. View angle is 140 degrees.

Jarvis Says: These require soldering so if you are not familiar with the process these are not for you.

The manufacturer, Elenco Electronics, says Bredblox, but what's in a name? This is just a nice little breadboard for electronic experiments. The Elenco Model 9830 measures 6-1/2" long x 2-1/8" wide x 5/16" thick with (2) power busses up both long edges and (63) double rows of more busses. The holes for components and jumper wires are approx .050" each and multiple boards can be interlocked via tabs and ports on the long edges. Now go invent something and get rich.

You get a 10ml syringe of white silicone heat sink compound for use as a thermal coupling for electronics. High conductivity, low bleed and stable at high temperatures. Perfect for you electronic tinkerers out there with a sinking feeling.

Good things come in little packages. In this case the package is a 1-1/4" x 1-1/4" x 1/2" modulator, and the good things are a circuit board with at least a trimpot, electrolytic capacitor, assorted coils, 3-pin connector, RCA plug and (2) pop-off covers. Have a blast.

When you could just order this 480-pack of 1/4 watt, 5%-tolerance resistors. You'll get (30) pieces each of 10, 22, 47, 100, 220, 470, 1K, 2.2K, 4.7K, 10K, 22K, 47K, 100K, 220K, 470K, and 1M OHM.

This solderable perf board for the electronicshobbyist measure 1-1/2” x 1-3/4” x 1/16” or 3-1/4" x 2-1/2" x1/16" with 1mm dia copper pads on one side with holes sized for componentleads. Has 1/8" dia mounting holes on the corners.

We’re unsure what this take-out was taken out of, but it’s a 2-1/4” x 1-3/4” PC board with comparator IC (integrated circuit), plus (1) yellow and (4) red LEDs, assorted resistors and a trim pot. Also, red and black leads with inline ring terminals, and a momentary push-button switch.

Like a third hand in the electronics lab, this circuit-board rack from Elenco® has a pair of stable 6-1/2" legs and 3" tall arms with clips, one spring-loaded, to hold the board. It's a must for any electronics DIY-er. Adjusts from 0 to 9-3/8" apart and lets you rotate the board it holds a full 360 degrees. Both clips and legs lock with thumbscrews.
