2016 raffle tickets

I am picking up the raffle tickets at the printer tomorrow. I am planning to be at coffee on Saturday (Jan 30th) if anyone is interested in signing out a book or several.

 

Voltage Regulator Modules

regulator board

 

A whole range of small regulator boards or modules are available from your favorite on-line shopping sites for very little money.  I gave the most recently arrived unit a quick once over.

The on board voltmeter is fairly accurate but if you need to adjust voltage exactly I suggest a good multi-meter.

I measured quiescent current at 25 mA (compared to 5 mA with a 7805).

Voltage regulation was good; switching an 11 ohm load at 5 volts did not result in a noticeable drop.  The regulator IC stayed cold – at least until the load resistors started smoking.test setup

I put my scope across the load and found an interesting [Eastern Rockies] waveform about 0.5 V at 10 KHz.

There is one 220 uF electrolytic across the output.  The scope suggests that some additional output filtering is in order.

 

All in all a useful piece of kit for only a very few dollars.

using “bargain” coax connectors

die on incorrectly threaded so239

 

I bought a package of 10 SO-239 chassis connectors on eBay at a great price.  The connectors looked good, teflon insulation, gold plated pins.  However it was not possible to thread a PL-259 male connector on more than 2 or 3 turns.

I then understood why the price was so low.  I decided that the solution was to re-thread the connectors.  I looked for a die at local tool stores but no luck –  I was told that 5/8-24 was a thread used in electrical connectors but not commonly used by machinists.  Checking on Amazon it became clear that the proper die was available at reasonable cost as a “gunsmiths” die.

 

As soon as it arrived I tried it.  I did not have a holder for this size die so I used a “Quick-clamp” with rubber pads.  I used lots of cutting oil and took my time cutting the threads.  The result was a bare brass thread which easily took the Amphenol PL-259 connector.

I don’t know if the manufacturer in China used a 16 mm die in place of 5/8″ or if they failed to take the thickness of the nickle plating into account when cutting threads.  Whatever the reason now I have the tool to make it right!

 

The photos tell the story.  73 and keep on building.  Earl VA6TJ
