[Mok Young Bacq] works on the weekends for mobile game monitoring service. He has three cellphones that he uses for work, and although you would think this means he could work from anywhere in the world, the roaming charges are a killer. His solution was to build an incredibly intricate machine that can use three different cellphones (PDF) on his behalf.
Above you can see it perched underneath the apex of the ladder, but you’re definitely going to want to watch the video after the break. This interface method uses a camera to look at each phone. It’s hung pointing downward and moves like a pendulum to look at one of the three screens at a time. Each phone has one servo motor for each button, which uses a flexible cable as an actuator. Now he can take trips abroad, just checking in over the Internet for his two 17-hour weekend shifts (10am to 3am the next morning) working the phones.
This reminds us of the cellphone endurance tests. What happens when a button stops working?

Global CALCnet lets you connect your TI graphic calculator to the Internet and use your favorite services like instant messaging and Internet relay chat. It also provides the option of worldwide multiplayer functionality for games ported to the device such as Scorched Earth and Tetris. We looked in on [Christopher Mitchell’s] CALCnet in December when it was being used to create local area networks with the adding machines. He’s taken that up a notch with a helping hand from Arduino. An Arduino board is used to connect the serial communications from the calculator to an Internet connected PC via the Arduino’s USB capabilities.
Think this will waste a lot of time in schools? Unlikely since an Internet connected computer is integral for this system to work. If you have a computer in front of you why waste time on the calculator network? Still, how hard would it be to build a WiFi module that can directly connect them to an access point? That may be a moot point as the Slashdot article that pointed us to global CALCnet also links to a calculator port of DOOM. It runs quite well, as you can see in the video after the break. This is a must-have for anyone owning a TI Nspire that can run it.

How often does this happen to you? You’re leaving on a long trip, and half way there you remember the TV was left on. Never? Alright then, how about wanting to control an Xbox 360 from within the other room and you don’t have the remote. Still a rare occurrence?

Start off with a beat, wood sticks on cigar boxes will do. Add some chimes as accent, a Farfisa organ or record player for a voice, several other instruments for harmony and dissonance, and you’re still just on the tip of the iceberg for understanding Cybraphon.
Not only is this antique wardrobe completely autonomous, playing music with over 60 robotic instruments, its song are based on the current mood of the internet. You definitely don’t want to miss the video (or pictures) on this one, catch it after the rift.

Today we received the question,
“How to control a web cam via internet,
i want to use it for security reasons, always out of the house and my PC connected want to open the cam from time to time to checkout if something wrong!!”
– [Mohamed Saleh]
What a fun project we thought! And so many different ways of tackling it. Find out what we suggested to [Mohamed] after the break. Continue reading “Ask HackADay: Network Security Camera”
It’s got a NIC, a remote, a character display, and can record and play back streaming audio. Thumper is [Harrison Pham’s] contest-winning Internet radio player.His finished board is roughly the same size as the 16×2 character display and piggy-backs the device for a small form-factor. It can be controlled via an infrared remote control, or through a remote web interface. Source files are available from the link at the top, but the really juicy details are included in the shockingly comprehensive PDF writeup.
The photo above is a bit misleading. The board has a micro SD slot on the back even though a USB card reader is shown. This project would need USB host control for Propeller chips in order to use that reader. Don’t forget to check out some of the other submissions to the the contest once you’ve had your fill of this one.
Project Thunderbird is an automated predator and pest control system. It consists of a pellet gun mounted in a motorized base. The icing on the cake is a 60x zoom camera that has cross-hairs superimposed on the picture. This reminds us of the Internet hunting for the handicap we heard about years ago.
In the video after the break you can see how the motorized base works, watch the trigger-pull motor, and observe a demonstration of some target practice. The creator, [Gadgetapodimus], mentions the possible sale of plans and kits as soon as he completes the system. Perhaps it would be better if this was not easy for people to build.
