An intro to Pen Plotters 

I’ve been fascinated with pen plotters for a long time now and I’ve owned several of them – but for some reason never posted any of my explorations or findings online. Until now, at least. You might wonder what’s so special about pen plotters? Well, let me tell you. Pen plotters are friendly robots

Night Timelapse of the Milky Way from an Airplane Cockpit

Just as the bright city lights are vanishing behind us, the Milky Way starts to become clearly visible up ahead. Its now us, pacing at almost the speed of sound along the invisible highway and the pitch-black night sky above this surreal landscape. Ahead of us are another eight hours flight time, but we already stopped counting the shooting stars. And we got already to a few hundred.

A Mind is Born

In 256 bytes, Linus Åkesson has produced not only an incredible set of visuals, modulating and morphing sierpinsky gaskets, but a beautiful, driving, piece of music.

He goes into depth about how it was made. The code can be seen below, in all its inscrutable wonder:

Mad Max Survival Technique: Solar Still

Should you find yourself in a post apocalyptic wasteland ruled by water-hording warlords, please remember the solar still.

One of the most significant survival tools created in the last 40 years, the solar still was developed by two physicians working for the U.S. Department of Agriculture. Results of extensive testing in the Arizona deserts by the U.S. Air Force proved that when properly assembled, the still can save your life.

There are only 2 essential components to constructing the solar still — a container to catch the water and a 6 x 6-footsheet of clear plastic. A shovel or trowel, a length of plastic tube and tape are all optional.
The container can be a collapsible cup, an empty plastic bottle, a small cooking pot or just about anything with a large enough opening to catch falling drops of water. In a pinch, even tin foil or a sandwich bag can be fashioned into a workable receptacle.
The sheet of clear plastic can be a ground cloth used under tents when backpacking or a thin painting drop cloth. Both work well as long as there are no tears or holes. This is the one item that should be carried at all times, since there is no natural substitute out in the boonies. I keep a 6 x 12-foot plastic drop cloth taped inside my daypack, large enough to make two stills if necessary. Some desert rats like to keep their plastic sheets folded inside a hip sack or as part of their first-aid kits.
A 6-foot length of flexible plastic tubing, similar to the kind used in fish tanks is a non-essential but desirable addition to the still components. This will allow you to drink accumulated water without needing to break down the solar still, inevitably affecting its efficiency.

So you like cold drinks, especially in the heat of the summer. You also like large drinks, however, they come at a cost: unless you can drink a superhuman quantity of liquid in a relatively short period of time, your beverage is gonna get warm. This is unacceptable. Enter the “Stein Of Science“. A full metal jacket around a cryostatic dewar with a hefty steel handle.

You know you want one.

The Black Blood of the Earth

When Subject 1’s cup of unadulterated was half empty, he grabbed his water bottle and poured the remainder into his clear glass coffee cup. He looks at it and then puts his hand up because He Needs An Adult. He said with concern, “I added water but it didn’t change color.” We all wandered over to peek into the dark heart of his mug. Even diluted to 50% of the original strength, it is still as black, oily, and potentially lethal as a tar pit.

While accurate, this can’t merely be called Scientific Coffee or even Weapons Grade Coffee. My brain went searching for terms that accurately described this creation. While the tar entity that killed Tasha Yar in ST:TNG came to mind, John Carpenter’s “Big Trouble In Little China” is what stuck. This coffee is the Black Blood Of The Earth (or BBotE for the sake of brevity).

With 145 cups of coffee’s worth of caffeine in 5.7 cups of volume, this is emphatically a beverage not to be trifled with. more importantly, though, it is fantastically delicious. Any comparison to regular coffee is, at best, fraught with peril. This is like comparing apples and bazookas.


Go get some.

HowTo: Raspberry Pi ad-blocking, caching router and internet gateway

This past week, during a transition between internet accounts from the same provider ( gotta love monopolies! ), I setup a rasberrypi b+ as a temporary router using a 4g cellular hotspot as our primary internet connection.

The maximum data plan available through t-mobile provided only 21GB of data for $120 a month. At 4g LTE speeds, ~50Mbps, you can burn through 21GB in just about an hour.

Clearly, we needed to figure out ways to conserve bandwidth, particularly for an office of 6-8 people all sharing the same connection.

Enter Privoxy, Polipo, Dnsmasq, and some iptables magic.

So, first off, I’m assuming you’ve got the latest Raspbian installed. This was built on the 2014-12-24 release.

So, lets add the usb0 network interface and set it to get an ip address via DHCP.
/etc/network/interfaces

Next, lets go get all the software we’ll need to get this done:

Avahi is just because I don’t like to type IP addresses…

Next up is /etc/dnsmasq.conf for providing dhcp service for our network:

Then Privoxy

Next, we’ve got polipo, our lightweight caching proxy: /etc/polipo/config

I’d reboot at this moment, to make sure everything comes up roses, plug in your android phone or hotspot setup to do USB tethering.

Then, finally, the iptables rules that do that magic:

Now, you should have your ethernet port serving up IP addresses to your lan, routing all traffic through privoxy and polipo to cache, and serving dns requests locally to your caching dns proxy.

Nota Bene: Should work with iPhones, but you’ll need to install some extra tools and configuration.
