Split core RFI line chokes, in two sizes.
These are high quality
chokes, easily snapped
onto power cords, telephone cords, and other lines that are acting as
antennas. The smaller one handles lines or cables up to 1/4" in
the larger up to 3/8." Smaller cords can be wrapped through
multiple times, providing greatly enhanced filtering.

Precision Electronic Tool Kit
The attractive zippered vinyl
case contains a 10 piece precision electronic tool set-- 7
drivers in slot and Philips heads, precision tweezers, 5" micro-nipper
and 5" miniature long-nose pliers. Pro'sKit quality all the way.
The right tool for the job-- sure, you can use a jeweler's screwdriver to adjust trim-pots and caps, but how often do you have to guess at the result because the tool is interfering with the circuit? The Pro'sKit Ceramic Driver (alignment tool) is non-inductive, non-magnetic, thermally and electrically insulated, and anti-static. The flat tip measures 2mm by 0.4mm, just right for most of the trim caps and pots you will find on circuit boards. The ceramic tip is rugged, and will last a lifetime if you don't try to use it as a screwdriver. There is a "palm pivot" on the end, so you can turn it through 360 degrees without having to reposition it, and it comes with a plastic protector for the tip.
Alignment Tool Set, ABS Plastic
ProsKit's PK-A001 Alignment Tool Set features 10 pieces with assorted ends. The material is rugged ABS plastic, non-inductive and a good choice for aligning RF circuits.

Stripping the insulation off of the end of a wire sounds like a simple job, but it is surprising how difficult it can be do do it RIGHT. The ProsKit PK-3001 Precision Wire Strippers are what you need for effortless stripping of the finer wires-- 20 to 30AWG (or 1.0 to 0.2mm for the metrically enabled). They cover the wire sizes that you will encounter most often in electronic work, from standard hookup wire down to the hair-thin wires used in headsets and ribbon cable. Well made, the PK-3001 will last a lifetime if not abused. Compare to other brands costing more than $20!
Forget "Dikes!" When you are trimming the leads on freshly soldered components, you need a precise instrument to trim flush, with minimum stress on the connection. Heavy, awkward "diagonal cutting pliers" do a sloppy job and you risk pulling the solder pad off the board. These are microscopically sharp, hardened steel, and angled for working in close quarters. They're the ones we use on the OHR workbenches!

From GC Thorsen, Q-dope
correct material to seal

drys quickly and fixes coils without affecting their temperature
inductance, or Q. It's supplied in a convenient 2 Oz bottle
We have had to discontinue Q-Dope primarily because of the cost. Its only advantage over clear nail polish or nail hardener was that it dried more quickly. Well, apparently it is known to the State of California that the solvent can be dangerous, so they changed the solvent and put the price up. At $8.95 for 2 Oz it was a pretty expensive replacement for nail polish, but in 2006 it got taken off the market again and then came back at around $12 a bottle, so we are dropping our recommendation for Q-dope. Here in our shop we have started using nail hardner and found the increased drying time to be a very minor inconvenience.

AC Powerstrip Liberator Plus.
How much of your expensive surge and overload protected AC power strip can't be used, because "plug-pack" transformers are blocking more than one outlet? Here's the solution-- the Powerstrip Liberator Plus is a 12" AC extension cord. Move those big transformers away from the power strip and regain the use of ALL of your outlets-- yes, there's an outlet in the end of the PSL+ so you get to use the powerstrip outlet twice! 10Amp, UL listed.

Antistatic Wrist Strap.
Electrostatic Discharge (ESD) or static electricity can destroy sensitive electronic devices without your even knowing it. Worse, the damage can be done but not become apparent for months or even years after the event. To avoid ESD you should always be grounded when working with sensitive components, but if you remember your basic electricity studies you do NOT want to be grounded when you are working with electrical equipment!

into it, so static electricity will discharge slowly and constantly,

|Kester 951 Solder Flux Pen $6.50|
Kester's "245" No Clean Solder is the perfect solder to use for electronic kits. It leaves little or no residue on the board, but flows on smoothly and does a great job. Our handy sample pack contains 15 grams (about 12' length) of 63/37 flux core solder (.031" diameter) or enough to do most any kit. Highly recommended for our OHR Kits.
solder fluxes (including Kester's famous "44" formula) leave
residue on the circuit board. This residue is unsightly, but
to the point it makes it difficult to see the solder connections in
detail, and over time the residue can break down into conductive salts
which can cause corrosion problems and short- circuits. You generally
need to remove the residue before installing a circuit board, and the
chemicals used to flush off the residue are themselves harmful to the
technician and/or the environment, and require special
There are water-soluble fluxes available, but they are
not as effective. Kester “245” Low Residue Flux is classified
as Type ROL0 flux under IPC
ANSI/J-STD-004 Joint Industry Standard. This flux was formerly
classified as Type LR per MIL-F-14256.

Very similar in performance to Kester's No Clean formulation, this Chinese product is a real bargain at barely half the cost of the Kester solder. The spool is a full Kg or 2.2 pounds, in .048" diameter. The alloy is the same 63-37 and the flux is RMA, low residue, but details are lacking. We've already adopted it on one of our production lines here at Milestone Technologies.
