Ha, ha! Isn't that the truth. Only thing cheaper is a "free" DMM from Harbor Freight!

$6.95 is cheaper than any LED meter at Adafruit:

Here is my original email from April 2015:

It took over a month, but my Chinese buck converters and heat sinks finally arrived!

10 Adjustable Output Buck Converters - $11.30 (no shipping fee!)
20 Heat Sinks - $3.51 (no shipping fee!)

These are just the things to use with orphaned laptop power supplies.

Portable power pack

sigcom1
 

Doug Hendricks has succesfully used a $1.25 XL6009 I.C. (500 KHz) boost module, a $0.99 LED DC meter module, a couple of push-button switches along with a PCB, cell holder and Altoids tin to produce what we call the "Pixie Portable Power Pack". Power is supplied by four AA cells (alkaline or rechargeable) then boosted up to the required operating voltage. It's a compact unit and everything fits inside the Altoids tin, with the lid closed! One push-button switch is used to read the battery voltage and the other the output voltage which is set using the on-board pot on the boost module; accessible through a tiny hole drilled in the tin. Load current capability is a few Amp's.; enough to operate all except the 'hungriest' of QRP rigs. No RF noise has been detected thusfar with the unit running under load.

This neat little gadget is part of the ongoing Norcal Monthly Meeting "Pixie Project" which is a series of free kits produced by Doug and given out at the meetings with members constructing their kits at home and bring them to the subsequent month's meeting. All this will culminate in an indoor Pixie Operating Contest later this summer.

Photographs of the PPPP have been posted to the Norcal Yahoo Group, "Photos" section. <https://groups.yahoo.com/neo/groups/norcalqrp/info>;

Hi Guys,
I try to pick up some of you but I have to be outdoors and I use a 65 foot vertical end fed.
I hear W1AW about 559 and QSB.
I'm now using my old MFJ CW rigs but all my morning contacts are not much more then 100 miles.
Humidity is so thick I saw a few Perch go by
I operate from the car but I don't like to idle for 2 hours with the A/C running.
Waiting for UPS for my other Guitar.

It is small - tiny actually. Comes with a tabbed little plexi shield "box" and two little red plexi button extenders, plus two screw to hold it together.

Re: Neat little DC-DC Module

I purchased something similar called a Buck converter for powering my qrp rig and attachments to it like a Zero-Beat, Hi-Per-Mite, etc.
I use it to bump down approximately 18 VDC from a set of 4 Lipo batteries down to 13.8 to a little junction box that distributes power to 4 outlets.
Really like the setup...plenty of power so far.
Will get to really test it out during the upcoming Field Day events.
