Building the mind of a robot overlord

April 19, 2012 By 8 Comments

The folks at the Louisville hackerspace LVL1 now have a fabulous piece of wall art that is also a speech synthesizer. The speech synthesizer is over two feet long and is made of nine panels of stripboard connected with right angle headers. An awesome piece of art if there ever was one.

This speech synthesizer is actually 30 years in the making. In the early 1980s, one of the members of LVL1 across a few text-to-speech ICs in a bin in Radio Shack. These ICs sat in a drawer while college got in the way, and in 1990, the project was resurrected. The speech synth chips sat in a drawer for another decade, and it was finally decided to build a wall-mounted speech synth for LVL1.

This speech synthesizer is intended to be the voice box for FATHER, LVL1’s second hackerspace AI. Already the first AI – MOTHER – is already telling people to take out the trash and generally trying to become the AI-gone-amok we all deserve. FATHER will be implemented in a robotic monkey, so right now the only question we have is who has been messing with the Louisville water supply.

Controlling blinkenlights with modern computers

April 19, 2012 By 4 Comments

A few old timers may remember that once, long ago, computers didn’t require keyboards. The earliest personal computers such as the Altair 8800 and the server rack-sized minicomputers like the PDP-11 could be controlled with a panel filled with switches and lights, giving us the term blinkenlights. Today, most of these machines have been thrown away or locked up in museums and private collections; even if you were to get your hands on one of these control panels, you’ll have a heck of a time doing something useful with one.

Fear not, because [Jörg] has come up with a great way to control these blinkenlights and simulate the computers of yesteryear. He calls his build BlinkenBone, and it’s able to control the blinkenlight panels from dozens of historical computers and simulate every thrown switch and tiny light bulb.

BlinkenBone is a BeagleBone single board Linux computer running the SimH simulator for antique computers. Right now the BlinkenBone is able to simulate the PDP-1, PDP-8, PDP-11, a lot of old IBM machines, the Altair 8800, and even some HP boxes.

Without a BlinkenBone or similar simulation device, the still-surviving control panels for these computers are just pieces of art to hang on a wall. When they’re running a simulation of their original hardware that was long-lost to the scrap yard, they become the useful devices they once were. Also, it’s much easier to appreciate how far technology has come in the last 40 years.

You can check out a short demo of [Jörg] using his BlinkenBone on a PDP-11/40 after the break. Look at those lights go.

Automated Beer brewing

April 19, 2012 By Leave a Comment

[Randyrob] is pretty serious about their beer. So serious, that he wanted to build a fully automated system for brewing. Dubbed the Halfluck Automated Brewing System, or HABS, it is actually his first micro controller project. You can follow along on the arduino forums to get a little more information, including the source code if you should want to build one of your own. There are a few videos on his youtube channel, but unfortunately, we didn’t notice any full tours of the entire thing.

Like some others we’ve seen, this one only handles the brewing aspect, not the fermenting stages. It would be interesting to see a system that handled it all. You could fairly easily get the machine to siphon it into a keg for final carbonation too.

2 horse power 3 wheeled beast

April 19, 2012 By Leave a Comment

This beast above is the result of what is probably the coolest class project ever.  The instructors[Michael Ham] and [Kenny Ham] gave their students a pile of junk and said “build something”. The goal was a “vehicle that could recharge itself”. In the pile were motorcycle tires, an old classroom seat, the front suspension from a VW bug, some old power drills, a solar panel, and a battery, amongst other bits and pieces.  What you see above was the result.  While it may not win any drag races any time soon, it was a fantastic class project that had the students thinking their way around many problems.

The videos on the project page show that this thing isn’t quite as sluggish as we would have expected for its size.

How to properly fly with electronics

April 19, 2012 By Leave a Comment

Some electronics professionals have to fly relatively frequently. One such person, [Steve Hoefer] shares with us how to properly fly with your exposed wires and bits without getting nabbed by the TSA for suspicion of being a terrorist. The article is fairly in depth with tips on how to handle most situations including being pulled aside and put in a tiny room for questioning. Most of it boils down to the fact that you can’t expect the TSA agents to be experts in everything. They see stuff that is slightly out of the norm, they have to follow up. We’re not talking about pat-downs and body scanners here, we’re talking about circuit boards, duct tape, and battery packs.

One story [Steve] shares is especially humorous. He noted that the servos had been disconnected from one of his robots. He wonders, why disconnect them? If they were suspected of being an explosive, they shouldn’t have messed with them. If they weren’t… why did they un-plug them?

You're invited to sift through 100 Terabytes of data for NASA

April 19, 2012 By Leave a Comment

Most people we know had at least one phase where they dreamt of working for NASA. That dream may have faded for many of us, but it could suddenly be a real possibility again with a tournament NASA is holding. The goal is to sift through all of the data that they have collected; roughly 100 terabytes of pictures, telemetry data, top secret pictures of martian yeti, and models. All of this information was gathered over different missions, on different instruments, in different formats. It is a mess. Take this data and make it easily accessible to both scientists, and non-scientists. They want their information to be useful and compelling to the world.

The grand prize for your fantastic final result is $10,000 and the title of “Space Coder of the Galaxy 2012”.  I know I’d settle for a week at space camp.

Note: I just noticed the following bit:

And one talented high school winner will receive a special VIP invitation from NASA

I’m not sure if that means this is for high schoolers only, but I’m pretty sure it means a lot of them won’t identify with that space camp link above.
