Sure, this will seriously void the warranty on your TV but that’s what surplus store are for. The mod is pretty straight forward, you are feeding audio signals directly into the deflection inputs on the cathode ray tube of the set. This will cause the electron beam to paint not a regular image but something more along the lines of what you would get from an oscilloscope. I have a 5" Bentley portable TV that is just about to go under the knife for this mod. If all works well I should have some video of the results pretty soon.
If your looking for a nice turn key solution for learning microcontrollers this could be for you. The Thames & Kosmos Computer systems engineering kit has pretty much every thing you will need to get you started with electronics and microcontrollers:
microcontroller module
dual digital display module
3 transistors
7 light emitting diodes
motor
light sensor (light dependent resistor)
temperature sensor (negative temperature coefficient type)
Just great. For a long time I have been trying to figure out a way not to let Quicktime spawn web pages. Not only is it annoying but now it can get you phissed:
It begins with a QuickTime file being embedded in a Profile page. If the user “runs” the file (simply visiting the infected page is enough to trigger the attack in most cases), it uses the HREF function to activate some JavaScript.
Allowing JavaScript from a movie file….whoops.
When this happens, the profile page is “infected” and pastes a fake overlay of options onto the profile page – the most serious of which is (of course) the fake login button. If your page has been affected, you will see a strange, blue navigation bar such as this on your page. If this is the case, you will need to clean out your profile and check if any of your friends have also been infected – if they are, you will continue to be reinfected…most likely via the friends list itself. We have seen reports of users complaining that even when they’ve removed the fake navigation bar from their page, it comes right back if one of their friends is infected – so it looks like the friends list is being exploited in much the same way the Orkut worm used a similar feature to spread. Except in this case, the only option to fix the problem is get your friend to remove the infection code from their page, or remove your friend from your list indefinitely.
Going back to the fake login, if you enter your details, you have officially been Phished.
I saw this a few days ago on Boing Boing. After seeing how under certain circumstances ice crystals in the air can reflect lights on the ground It’s easy to see how these could be mistaken for UFOs.
BOINC, or ‘ Berkeley Open Infrastructure for Network Computing’ is the just the thing if your into getting the most out of your extra CPU cycles. Years ago this idea made headlines when SETI@home was started and you could download a program that would sift through the volumes of data that was collected by radio astronomers in the hopes that a sign of life could be found off our own planet. The software has evolved into a common set of tools that can be used to churn out results for everything from climate change to computer animation. For a full list of projects you can take part in go here and of course you will need the base software and thats avaliable when you follow the link: BOINC
Having the Christmas spirit and wanting to build something will make for a productive week. In my office it was announced that there was to be a contest to see what department could make the best Christmas (er, ‘winter holiday’, sorry) wreath. The guide lines were pretty vague on what the content was supposed to be so I chose to make one that properly reflected what the computer department is like. So, armed with a standard issue wreath I set out to wow ’em big time!
First thing I did was wrap the wreath in a string of 70 LEDs. These things are super! the control device has a jaw dropping 16 settings. All sorts of cool cycling and blinking going on there, sure to cause a fit or two.
Next I decided that to was going to have a big bow. All proper wreaths have them right? But mine was going to be unique. No run of the mill floppy plastic felt bow for me, no sir! I was going to make mine high tech. A while back I had bought a Juice Box MP3 and image player. I had a grand idea that I’d use it as a desktop digital picture frame. I didn’t like the way it displayed the images so I chucked it in a box for later. Making a bow that had it’s own slide show would be quite simple with the Juice Box, it’s small enough to cover with other parts and it does the job of image display good enough for this project.
I knew that I’d have to cover up the interface between box and screen so after walking around a craft shop for a while I struck upon the idea of building a micro wreath to cover things up. Using three different kinds of fake cranberries, I un-wrapped all of them and then twisted them on to a wire frame.
After the frame was built I started work on the bow. The bows that I could find that looked good are made up of discreet stapled ‘bow-ets’. I don’t know what the correct name is, maybe it’s a ‘sub bow assembly’. Whatever. I took each of the small bows and added two staples on either side of the center staple. I removed the original staple and cut the bows in half. I used a scrap piece of black matt-board to cut a frame around the Juice Box screen, to this I started hot gluing the bow halves to.
Once the bow was pretty much back in its original shape I covered the edges and the gobs of hot glue with some bow scraps. After that I wired the mini wreath to this and shaped the wire to obscure the edges of the bow.
To secure the Juice Box bow to the wreath I zip tied a stick of bass wood at the bottom front of the wreath. On the back of the Juice Box I glued a similar stick on the top so I could wire them together. I needed to be able to swing the bow up in case I needed to make a battery change. I know, I could use a 4.5 volt AC adapter but I couldn’t find one and I was feeling clever.
Using more hot glue I attached short bits of florists wire to all the parts that are going the be infused in the wreath. The numbers are just ones and zeros that were cut into strips from a single 11×17 print out. The hard drives (not pictured) are form some old laptops that were hiding under a desk. Their 360 MB capacity platters will look nice and pretty once the lights start reflecting off them. The CPUs are AMD K6/450s that were removed from computers that were to be sent to surplus.
I needed a nice ‘Happy Holidays’ sign in it someplace so naturally I chose the keys off from the scrap laptops. Those 386’s never saw it coming! To make sure the keys were all lined up on the wire frame I taped them to a metal ruler. Never under estimate the power of magic tape! Handy stuff.
I secured a length of flipped over tape to the ruler and set out the keys. I started at the center of the keys and tacked the ends of the wires. Once all the keys were glued to the wire I then ran small bits of wires to hold the lower line of text in place. A smart curve later and I was ready to wire it in place.
The placement of all the parts didn’t follow any structured organization. I knew that the big things, the hard drives, needed to go on first. I worked on making a loose balance in the composition. No big clumps of stuff in any one place.
Once everything was together I added a bunch of photos to the Juice Box using Christopher JBP image converter and I was all set.
I’m happy with how it turned out. It may not win the first prize (it’s lacking in kids and animals) but it’s bound to cause a stir. I like the iWreath, too bad it doesn’t play music.
