[Claude Paillard] makes his own triodes (google translated) for short wave radios. The site doesn’t have a lot of details itself, but links to entire books on the history of radio tubes and manufacturing of them. [Claude] takes us through the entire process of building a triode in a 17 minute long video. Even if you aren’t into them, this is fascinating. From the looks of it, several of us might only be a pump or two short of being able to cobble one together.
We spent our Halloween dressed as an irate traveler as we flew cross country, but it looks like a lot of people were having much more fun. [flaming_pele!]‘s Aliens power loader is one of the best costumes we’ve seen yet. He built it by referencing a 1/12th model kit and a lot of photos. The final costume is about 80% full size which gets it under their 8 foot ceilings. There’s a video of the suit embedded below. Our love of power suits was documented fairly well in our roundup post this summer. Make found two other related costumes: a Star Wars AT-ST and a generic mech constructed from packing foam. Did any of you dress as something truly nerdy for Halloween?
With the recent announcement and release of their ADK, it was only a matter of time before Google started invading your home in a big way. From the looks of it, Google will be jumping into the home lighting market very shortly, which could prove to be quite interesting.
Partnering with Florida-based Lighting Sciences, Google is planning on developing consumer-grade 60W equivalent smart LED light bulbs. The bulbs will be able to wirelessly communicate using Google’s new open-source home networking protocol. The lights will be controllable using any Android device allowing users to dim, brighten and toggle the lights on and off without ever touching a wall switch.
We think it’s an interesting idea, and we’re all for getting quality LED lighting in the home. That said, some of Google’s other utility-centric endeavors such as PowerMeter have met only mediocre success, so it remains to be seen if this concept takes off. If it does however, we can’t wait to see the flood of ADK-based hacks the community puts together. Since their new wireless protocol will likely be extended to all sorts of other household systems, the possibilities are endless.
Capture the Flag (CTF) is a long running tradition at hacker conventions. It pits teams of security researchers against each other on the same network. Every team gets an identical virtual machine image. The VM has a set of custom written services that are known to be vulnerable. The teams work to secure their image while simultaneously exploiting services on the machines of other teams. A scoring server monitors the match as it progresses and awards points to teams for keeping their services up and also for stealing data from their competitors.
The Chaos Communication Congress in Berlin December 27-30, 2008 will host a CTF competition. Most CTF matches are done head to head in the same room. While 25C3 will have local teams, it will also be wide open for international teams to compete remotely. Remote teams will host their own images on a VPN with the other competitors. Now is a good time to register and familiarize yourself with the scoring system. It will certainly be interesting to see how this competition plays out now that teams that can’t make the trip can still compete.
whew! way to beat the heat by reading us on a lazy afternoon like this! I hope everyone shows up to our hackaday meetup tomorrow dressed properly and with water (no goth clothing. too hot)!
Yes, meetings will be filmed (our philly one at least) and we’ll later be providing the video for all who missed out to download and watch. see? we have <3s too. now before i run off and do calculus, let me explain something.
The CVS camcorder. I’ve got it rigged up USB and plugged into my Mac/Linux/whatever. It is not recognized which sucks. But, by holding down the record and delete keys while booting up, you get a system info menu. This reveals only a little (but some) information about the camcorder. It’s probably helpful to some people. Thursday at the meeting we’ll discuss how to get it rigged up with proper device drivers, etc. I’ve been talking with some people about getting DD out there because they’re needed. This isn’t as easy as all of us thought it would be!
In other news today, PSP 1.5 firmware is now open and “cracked”. You can run homebrew apps on your PSP finally. Check it out here.
The poor man’s U2 iPod has now been made. It’s basically throwing the U2 stuff on a regular old 30gb iPod. Cool none the less. I like the U2 iPod’s look a lot. [francis]
This is pretty cool too. It’s been around for awhile but it’s a full out project that deserves some recognition. It’s a MMOG version of GTA. Lotta C++ skill there. [xrosesxarexdeadx]
Your lazy afternoon hack: Beat the heat with a homemade air conditioner
I’ve gotten about 20 e-mails about homemade air conditioners and what not. So thanks to everyone sending them in to beat the heat. Ghetto-esque, but looks pretty cheap and effective. It’s done by shoving tons of ice water in a trash can, hooking it up to a fan to take in all the warm air and transfer the heat to the water. Then all warm water is pumped outside to…well, get rid of it. He says it cost $30 CAD to make so that’s not too bad at all. Someone try it out and let us know how it goes. You obviously must be pretty hot, but hey, if I hadn’t gotten this free A/C from my aunt/uncle, I would be building one of these in 5 seconds in my kitchen. Very nice.
