In the Makers Market: LED hula hoop kits

prodmod_hoop.JPG

From seller ProdMod, this cool kit for making your own color-changing LED hula hoop that collapses for storage like a band-saw blade:

Use this kit in combination with 10.5 feet of tubing (sold separately) to build your own LED hoop. This is the easiest of my kits to assemble. The battery lasts about 5 hours of continuous use, and can be easily replaced for a new one. This kit includes: One Lithium Battery, 12 feet of paired wire, One Slide Switch, One Tube Connector, 21 LEDs.

A rechargeable hoop kit is also available, which includes a rechargeable battery, a charger, and an integral charging jack to install in the hoop.

In the Makers Market:  Posc pocket audio oscillator kit

In the Makers Market: Posc pocket audio oscillator kit

The Posc is a battery powered, pocket sized oscillator. It has two square wave oscillators, one of which is controlled by changes in the user’s skin resistance over two metal contacts. The pitch of the second square wave oscillator is controlled by manipulating the amount of light received by the light dependent resistor. The Posc can be set to work in either stereo or mono output through a standard 1/4″ audio jack, so is compatible with a wide range of audio equipment. It is ideal for use with guitar amplifiers and effects pedals, PA systems, and can even be plugged directly into your computer or Hi-Fi audio inputs….A free effects rack for the Posc is also available from our software page.

Cool little 4-in-1 pocket tool

Cool little 4-in-1 pocket tool

Now, there are a jillion combination pocket/keychain tools on the market. I’ve owned, carried, and used a bunch of them, and I generally find that only the test of time effectively sorts wheat from chaff. I’ve never owned, carried, or used this so-called “screwpop” tool, so I have no way of knowing how it stands up to pocket wear. I’d be a bit nervous that the reversible hex bit would get lost somewhere along the way, although it looks like their bit features a ball detent to hold it in place. Also, for those of you are counting, the “fourth” tool–besides the bottle opener and the flat and phillips screwdrivers–is a 1/4″ hex nut driver, which is a bit of a cheap marketing gimmick because what they’re really talking about, of course, is the socket that holds the hex bit.

But I like the no-frills design and the price is certainly right at $5. If I see one on a counter by a cashwrap at a hardware store someday, I’ll probably pick it up. [Thanks, Kurt!]
