Arduino + Hang Man = Hangmanduino

We saw this nifty little toy today and thought you guys might get a kick out of it.  Its called the Hangmanduino, and as you can probably tell from the name, it plays hang man. This was an exercise in simplicity, you’ll notice there is only a single control for the entire game. We thought that the design was pretty cool, especially the single control. We weren’t surprised to see that this is actually the very same control we featured previously. You can download the code yourself from his website, if you want to make one of your own.

Tiny GSM Alarm System

We’ve covered this sort of thing before, but there is something to be said for the simplicity of this tiny GSM alarm system by [trax]. The alarm system is designed to send the owner a text message when a sensor is triggered. This alarm only works with Siemens phones, but it shouldn’t be too hard to find one.  The alarm is configured via a dip switch on the board and can also be armed and disarmed by text. The brains of this system is a PIC16F84A. The code and schematics are included at the bottom of the page.

Starfish PBX Goes Public

Starfish PBX takes the very popular Asterisk telephony platform and adds an open source, fully functional web management interface. Asterisk allows you to be your own private branch exchange; think of it as your own telephone company. You can setup extensions in your home or office, configure an intercom system, implement a hold system with music, manage voice mail, and integrate Voice over Internet Protocol. Starfish PBX, available in alpha release today, aims to make Asterisk available to a wider user base by simplifying the interface used to setup and maintain the system.

Update: Foundation PC Cooling

August 31, 2009 by 30 Comments

coolupdate

[gigs], whose foundation-based PC cooling project we covered earlier, has posted his initial test results. There was a large debate going back and forth in the comments as to whether or not this would work, and hopefully this should clear most of it up. He used a 150W fish tank heater to simulated his system’s heat output, and used a quiet fish tank pump to keep the water flowing. Over 8 hours, he was able to maintain a constant temperature 16° C (61° F). While not quite frigid, this would definitely provide ample cooling for normal operation with some headroom for overclocking.

Chart of results after the jump.

[thanks to gigs for getting back with real data so soon]

Hacking DMM Tweezers

These Tweezers are pretty cool tools for anyone doing SMD components. We tried them out and found them very pleasant well made. They are able to identify components and take readings easily with one hand. One thing they are missing, however, is the ability to measure voltage. The people over at Openschemes decided to see if there was a way around that. As it turns out, the chip used in the unit already has the capability to measure voltage. They take us through the process of modding the unit to be able to take advantage of this un utilized feature. From the outside, the only difference is a new switch to set the mode to voltage. Great job guys.

Custom Cable Management

You would be hard pressed to find a hacker who doesn’t have in some form a rats nest of wires and cables behind their computer desk. [Antoine] decided to tackle the problem and came up with his custom built cable management system. There is little info, but he does say his setup uses Ikea Antonius coat hangers and some hollow tube. Its quick and wont leave a residue like some cable solutions, so long as you don’t mind a screw hole or two. We especially like how if you need to change your setup you wont have to re-zip tie everything.

I-Swarm Robot Update

I-Swarm_Micro_Robot_On_Thumb

Back in October we reported on the I-Swarm robotics project. [Travis] sent us some more information. These tiny robots are programmed optically and are able to respond to programming commands via an infrared signal. Locomotion is facilitated with piezoelectric actuators and the power to the units provided through a solar cell. It is not clear that this project is still ongoing as the I-Swarm web page lists a project termination date of 6/31/2008. That being said, the video embedded after the break was posted two days ago showing swarm movement and detailing the programming, testing, and hardware specifics.
