In the Makers Market:  Dead drop spike

In the Makers Market: Dead drop spike

For those of you who aren’t up on your tradecraft, a “dead drop” is a place where spies or other clandestine-y folks drop off items for later retrieval by other agents. A “dead drop spike” is a particularly ingenious little container devised for the purpose. Basically, it’s a hollow metal spike, with a threaded watertight closure at the top. You put your top-secret microfilm or whatever inside the spike, take it to your dead drop, and stomp it into the ground with your foot. Then you cover it up with a rock or a piece of trash or whatever. The lid has a pull-loop built into it, so that when your contact comes by later to clear the drop, he or she can grab the spike by the loop and yank it up out of the ground again.

When I first learned about dead drop spikes years ago, I had a bit of a nerdgasm and decided I had to have one. I scoured the tubes, but alas, no one was selling them. Imagine my delight when, a couple years later, I discovered that Brian Dereu of Hollow Spy Coins had added a custom-machined dead drop spike to his inventory. I ordered one immediately, and could not be more pleased with its quality. That was at least a year ago, and as far as I can tell, if you’re in the market for a dead drop spike, Hollow Spy Coins is still the only place you can get one online.

How-To:  Build a sandbag-filling jig

How-To: Build a sandbag-filling jig

I am glad that, so far, in life, I have not had to join the ranks of those umpty-many folks who, at one point or another, have suddenly found themselves needing to fill a whole lot of sandbags in a hurry. Hopefully, I will never be in that situation, but when and if I am, I’m going to try to remember this tutorial by Instructables user RiverOakRanch. The jig they describe allows one person to fill six tubes at once, helps to insure equal filling, and, most importantly, frees up another laborer who would otherwise have to stand there holding the bags open.

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

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.

Easy-Threading Sewing Needle

Sean @ Make: Online writes: You know, as long as human beings have been squinting and poking at the tiny eyes of sewing needles, it’s pretty amazing that it’s taken so long for some clever inventor to address the problem. These spiral eye sewing needles are available direct from their inventor, Pam Turner of Minnesota. […]
