Hack Your Door to Lock and Unlock via Text Message. @hahn: I don't know about all that. With the right safeguards in place, I think this would be secure enough for my tastes: 1. Ensure it only responds to messages from ones' own phone. (Perhaps with a log of attempts from other users.) 2. 3. 4. 5. 6. Believe it or not, I'd feel a bit more secure with this system (with some tweaks) than a traditional lock-and-key system for the same reason I feel better about having extraneous cards in my wallet: If my phone (or overstuffed wallet) is missing, I'm going to know it. Top 10 Ways to Turn Your Retired Gadgetry into the Technology of the Future.

Hack an old monitor and 3D glasses for instant privacy. | Megadgets. DIY Projects, Inspiration, How-tos, Hacks, Mods & More @ Makezine.com - Tweak Technology to Your Will. By Ken Sharp April 25, 2005 Digital Video Recorders (DVRs) have become a necessary luxury over the last several years. Millions of people rely on these devices to pause and rewind live television, and to keep track of broadcast schedules and record programs for them.

Many consider them just as essential to their daily lives as their cell phones. Several months ago, I finally became sufficiently jealous of the millions of DVR owners to motivate me to put a DVR in my own living room. But I wanted something more versatile than a normal TiVo, ReplayTV, or Ultimate TV system. I envisioned an all-purpose media server that would function as a full DVR, but would also work as a music server and play console games. I earn a living as a computer engineer, so I understand how long it can take to write custom software. Here's how I did it. You'll need: with at least 256MB of RAM (512MB is better), plenty of hard drive space, and a good video card. presumably from your existing home theater system). 1.

Materials. How to Make a Static Electricity Generator—Shock Anything and Fry Electronics with Just a Touch! « NightHawkInLight. In the following video, I demonstrate how to create a device capable of charging the body of anyone who wears it with static electricity, allowing a powerful shock to be discharged into anything that is touched.

This grants the wearer the ability to do some pretty amazing things, some of which are shown in the first segment of the video. The parts used in this project are fairly inexpensive, totaling about $30, assuming some things are already lying around the house (such as spare wire and tape). In the list of parts below, I give some information to help locate the harder to find items.

Parts that can be purchased online: Negative ion generator (ionizer) (I bought mine here—search for SW-750) Automotive power converter (cheapest here, or find one at an auto parts store) Parts that can be purchased in a hardware or electronics store (such as RadioShack): Flux core solder 2" of copper wire Heat shrink insulating tubing (optional) 9 volt battery (DO NOT USE A LARGER POWER SOURCE! Tools: Build a Touchless 3D Tracking Interface with Everyday Materials. Combine low-tech materials with some high-tech components and build a completely Touchless 3D Tracking Interface. Explore capacitive sensing by using several panels of cardboard lined with aluminum foil. These panels, when charged, create electric fields that correspond to X, Y, and Z axes to create a 3D cube. With the aid of an Arduino microcontroller and some supplied code, movements inside the cube are tracked as your hand moves around inside the field. For Weekend Projects makers looking for an introduction to Arduino, this is a great project to learn from.

Once you’ve gathered all your parts, this project should only take a couple hours to complete – you’ll be playing 3D Tic Tac Toe before the weekend is over! Once your touchless 3D tracker is up and running, what you do with it is only limited by your own imagination!
