Potentiometers Plus Knobs
You pick the 500-Ohm 1/2W, 1K-Ohm 1/2W or the 10K-Ohm panel-mount potentiometer, all from Alpha Products® with dust covers over a 17mm base, panel tabs, 6mm dia x 10mm long shafts, and 3mm solder lugs with washers and nuts. Shafts are knurled and slotted, and single-turn. Turn them with press-fit black plastic knobs, 6mm ID x 16mm dia x 18mm tall with pointers in assorted colors of red, orange, yellow, blue, green and white.SHARE
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.

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.

Grow your own computer. This pre-wired Raspberry Pi 2 model B circuit board is essentially a palm-sized computer that you can hook a keyboard and monitor to, using it to learn computer science and coding, run a pet camera, open and close the door of a chicken coop, or write the great American novel. Make a personal weather station or a DIY gaming system; you’re limited only by your imagination and ingenuity. Has a Broadcom BCM2836, an ARM Cortex-A7-based quad-core processor that runs at 800MHz. You’ll be running Linux via a micro-SD card (which you supply) and 1 Gb of on-board memory. You’ll need a 2A power supply source into the micro-USB input. UL. Add a few bucks and put the whole little shebang in a clear ABS plastic case, 3-5/8” x 2-1/2” x 1”, that includes screws and feet.
