Let me disclaim that I’m a software guy, so I fully understand the deterministic nature of computer-generated random numbers. That said, bulding a “7 foot tall, 104 pound, dice-eating monster,” capable of generating 1.3 million random dice rolls per day is an extreme, to-the-max, over-the-top solution! In other words, exactly the kind of solution that sets a maker’s heart aflutter.

And while I may not understand what, exactly, correspondence gaming is all about, I’ve got nothing but respect for the maker of this beautiful behemoth!

Just a quick post to let everyone know that, contrary to appearance, Maker Nation isn’t dying the slow death of a neglected blog… at least not anymore.  I’ve got some exciting plans in the works for The Nation, far exceeding a simple blog, that I hope to be releasing soon…

In the meantime, I’ll be bringing the blog back up to full speed.  There’s certainly no lack of cool projects being done… I’ve just been lazy.

Also, if anyone is interested in contributing to the blog, drop me a line.  I think it would benefit everyone get more perspectives represented than just mine!

If you remember downloading the latest demoscene releases from back in the days of 2400 baud modems BBS’s, you know that demos were (are?) notorious for squeezing every last drop of performance from a processor with unbelievable realtime 3D graphics and wicked tunes. Seriously, a couple of those old Future Crew demos are still stuck in my head some 20 years later!

Well, Linus Åkesson managed to squeeze a very cool demo onto a 20 Mhz ATmega88 microcontroller with only 1K of RAM and 8.5K of Flash/EEPROM program space! It’s incredibly cool — a full-fledged demo with all the “classical” demo effects (3D shapes, plasma, starfields, fire, etc.)! Then when you consider that he’s doing all the timing of VGA signals in software and and still manages to generate waveforms for audio while the screen is blanking, it just boggles the mind (and says a lot about the ATmega88)!

Check out Linus’ site for build details, lots of explanation, and full source code!

I usually have to unclog a few sprinkler heads when I do my weekly system check, but I was in for a treat on Saturday when almost every single head was clogged! You see, the city did some work on the secondary water lines upstream from my house and, as a result, flooded my pipes with decades of sediment.

Always one to look for the bright side of any situation, I decided this was a good excuse to make a little sprinkler filter cleaner that’s been kickin’ around in my head for a while now. So if you have sprinkler heads with individual filters (like many RainBird, Orbit and Toro brand heads), read on after the break how to make one of these handy gadgets in about 5 minutes for under $12.

I’ll admin it: I’m a sucker for lasers, especially when they’re synchronized with music! This little project, which reminds me of something I saw in high school physics, is a perfect solution for those times when you only have a few minutes to make your living room look like discotheque — and if you haven’t been in that predicament yet, trust me: you will.

I doubt there’s a better project you can make lasers, a tin can, zip ties, popsicle sticks, clothes pins and some balloons… and if there is, I’d like to see it!

No build info on this one, but the pictures pretty much tell the whole story. It makes me wonder if the renaissance of film isn’t on its way, where you’ll buy boutique films from guys with big, homemade machines like this one in their garages.

Personally, I get goosebumps just knowing that someone built such behemoth because he wasn’t satisfied with the film you can buy nowadays. It’s the embodiment of the maker spirit!

Every time I head over to Matthias Wandel’s homepage (or his woodworking site) to see what’s new, I end up spending hours looking through all the cool projects! Seriously, what an awesome maker!

I thought I’d share the project that originally drew me to his a site in 2003: a mechanical CD changer/duplicator made mostly from wood and controlled via parallel port under Linux. While I’ve seen a few other CD changer projects, I think it’s safe to say this one is the original (and was probably the inspiration for the rest).

I think that every tinkerer should build something like this just because it’s such an interesting problem domain with so many details to consider, yet not insurmountable. I may just have to start my own CD changing robot this weekend!

After you check it out, be sure to poke around his site a while — you won’t be disappointed!

I’ve always been intrigued by the evil robot stylings of Captured! By Robots even if their music wasn’t really my bag, but this new video of New Zealand robo-band The Trons has finally given me something to look forward to when robots eventually takeover mankind.

Hikaru’s diary on learning to solder is a truly excellent (and unintentionally hilarious) tutorial on soldering. The lessons are spread across 10 “stories” that cover topics such as the history of soldering, iron selection (including how various types of irons work), soldering theory, as well as through-hole and reflow soldering — all with the comedic precision that only precisely translated Japanese cartoons can convey.

This tutorial is straight from Hakko, maker of some of the best soldering irons you can buy, so you know the information is good (if a little biased). It’s easily worth the 10 or 15 minutes it takes to read through, even if you’re already a pro.

There’s nothing I enjoy quite like tearing into an old printer or VCR to find some new crap for my parts box. Harvesting stepper motors, gears, belts and other mechanical bits is easy (and fun), but I’ve never really considered going after the electronics.

The folks over at uC Hobby have a cool writeup of all the parts they scrounged from an old UPS unit. I was surprised at how many nice parts they found, including a couple of lead-acid gel cells and a serious transformer that could be really useful in your next alternative energy project. And since they’re from a device that’s meant to handle lots of power, the parts are all pretty beefy.
