WAP Controlled Home Automation

December 22, 2008 by 8 Comments

[Josh] sent in a home automation project he did a little while ago. It has a total of eight switched outlets. The main focus of the project was WAP access for remote control from any cellphone. The control box is based on a design by [Ashley Roll] for controlling eight servos using a PIC microcontroller. A listener app written in Java monitors the control web page and sends signals to the board via serial port. He used opto-isolated 240V solid state relays for each of the outlets. All the pieces are available on the site and he might even do a custom control board design if there is enough interest.

Digital Clock Building

[punkky] has been documenting his adventures building digital clocks. They each use six 7-segment LED displays, but he’s been gradually changing how they are built. The first version used a CMOS BCD-to-7-sement latch on each display, which is tied to a PIC16F627a. For the next run, he added multiplexing, so he could drive all the segments using just thirteen pins. He’s posted a final schematic with code and details of how the clock timing actually works.

Tor Hardware Privacy Adapter

The Janus team have published a preview of their new Privacy Adapter. It’s a small two port router. You just plug it in-line between your computer/switch and your internet connection. It will then anonymize all of you traffic via the Tor network. You can also use it with OpenVPN. The hardware appears to be a Gumstix computer mounted to a daughtercard with two ethernet ports. It will have a web configuration just like a standard router. This looks like a great plug-n-play privacy device. The only improvement we would suggest is adding auto-detect so a crossover cable isn’t required.

Janus is responsible for JanusVM, a virtual machine designed to protect your privacy with technologies like Tor and OpenVPN.

Lately we’ve been focusing on multitouch technologies, but that doesn’t mean there isn’t interesting research going on in other areas of human-computer interaction. [Johnny Lee] posted a roundup of some the work that [Gonzalo Ramos] and others have done with pen based input. The video embedded above shows how pressure can be used to increase control precision. Have a look at his post to see how pen gestures can be used for seamless workspace sharing and how pen rolling can give additional control.

The Future Of Annoyance

[Garrett] posted about ThinkGeek updating the Phantom Keystroker to support random capslocking. You may remember that [Garrett] built the Stealth USB CapsLocker for April Fool’s day. The tiny device would randomly turn on the victim’s Caps Lock. This update to the commercial product has inspired him to refresh his own design. He suggests few possible options: random inserts, erratic volume control, or random sleeps. He’s also planning on making it more accessible to hacking. What would you add?

Measuring Current Through USB

[gmgfarrand] wanted to be able to measure the current being pulled through his USB.  He realized that even though he could just cut open the wire and measure at any point, a permanent tool for this would be quite useful.  This is a simple modification that shouldn’t take long. All you need is a spare USB cable and an enclosure. He ultimately filled his enclosure with glue to keep everything in there and solid. lets hope his soldering holds well.
