This one’s a riot! [Nico] got a new computer and didn’t want to change the six power supply cords he had strategically placed around his home and at work. So he just added a second charging jack that accepts a different style connector.
First off the laptop is used — but it’s new to him. So cracking it open and soldering in a new jack doesn’t affect the already expired warranty. He had an unlimited supply of Dell laptop chargers available from work. They are rated 19.5V and the charger for this computer is rated 20V so he figured this should be no problem. Instead of just swapping out the old charging port he added a second where the RJ-11 connector (for a telephone modem) was located. Now he doesn’t need to waste money buying more chargers for the new-old machine.
This isn’t the first time we’ve seen someone replace a power jack. But it is the first computer we’ve seen that takes two different chargers.
When we’re trying to get a relatively complex project to work we often end up with twenty windows open. When this happens we’re usually referencing multiple data sheets, webpages, and trying to write code that the same time. We’ve seen people with two or three monitors to alleviate the situation (often called a battlestation), but the we’re cheap and can’t justify buying more displays just for these occasions. Well [Oscar] may have the solution for us. His old laptop had been sitting in a box unused so he flipped the screen and built a stand to position it as an additional display on his desk.
The hack simply removed the screen for the hinged cover so that it could be flipped around. This turns the laptop into a tablet minus the touchscreen ability but that could always be added in later (we’ve seen it done with netbooks). He tells us that the only issue he ran into during this process was the length of the inverter cable. He simply cut it and spliced in a little bit of extra length.
[Oscar] didn’t write a post about his project, but you can see the build gallery after the break.

After receiving a Marconi from [Admiral Aaron Ravensdale] informing us of the completion of an exquisite steampunk laptop, we were simply delighted. [The Admiral]’s computational device, or Uhlian Calculator as is the preferred nomenclature, is a remarkable combination of design and function suitable for any remarkable gentleman bent on the domination of the fast approaching electrical frontier.
[Ravensdale]’s new steampunk laptop is built off his first laptop, an old Toshiba Satellite 1100. Not a speed demon by any means, but the quality of this build is phenomenal. The hinged keyboard tilts up into an ergonomic position when the laptop is opened, reveling a set of six LED jewels for the power, battery, and hard drive lights. To the left and right of the screen, a pair of miniature brass horns contain a set of stereo speakers.
The keyboard is an awesome modification of the stock keyboard very reminiscent of [Admiral Ravensdale]’s previous keyboard steampunkification.
[The Admiral] put up an Instructable going through the many hours he put into this fine piece of craftsmanship. There’s also a video showing the keyboard lifting mechanism and skeleton key power switch available after the break.

Remember the times before the iPad existed? When a tablet PC was actually a full computer in a tablet form factor? Yeah, those days we were all so very optimistic about the future of tablet computing. Don’t think we don’t appreciate the new amazing toys that we’ve got around with the plethora of tablets to choose from, but we still dream of fully functional tablet computers.
[Brian] wrote in to show us his build of a fully featured tablet macbook conversion dubbed the MessagePad. Though we’ve seen a wide selection of home spun tablets before, this one has an impressive list of added features. It boasts both front and rear facing cameras, an SSD drive, a built in Teensy, and a line-in. It doesn’t matter if you believe in the dream of a full blown pc in tablet format, or if your preference would have been a Windows or Linux machine. You’ll surely love the bevy of photos he took along the way as he was hacking and slashing on this thing.
[hackitbuildit], from instructables, has brought us a a DIY windows 8 tablet. To make the tablet, an old laptop is used that meets the minimum requirements of windows 8 preview, a touch screen conversion kit, and of course the software itself. The laptop is first prepared by removing the casing around the screen, and if you just go by the pictures it kind of looks like he is ripping it apart! Though if you look at the video screws are being removed.
The screen is flipped around and laid on the keyboard with a couple spacers between them, as many laptops use the keyboard area as heat sinking. The touch screen is installed, and some wood strips are hot-glued to the outside to fill in the gap between the screen and base. With a little paint you’re left with a large, but functional windows 8 tablet to get started developing for.
Here’s a fun art installation which you might run into downtown. It’s called the Dilemmabox and lets you pull a rope to up or down vote a question. [Christoffer Lorang Dahl] realized that touchscreens are wiping out a lot of really fun user interfaces of yore. He incorporated the two hanging rope inputs as an homage to doorbell ropes.
The built process works much like a laptop-to-digital photo frame conversion. The first step is to liberate the LCD screen from the laptop body. Both are housed in a wooden box, with a window cut out to show the screen. The mechanically clever part is the rope pulls. They’re both just pressing a key on the keyboard in a roundabout sort of way. [Christoffer] attached a smooth hemispherical piece to two keys. The ropes are connected to wooden levers which are held in place by springs. They rub on the hemispheres just enough when passing by to register a keypress.
The photo above was taken during the Dilemmabox’s brief appearance at a shopping plaza in Oslo.
One of the benefits of working in IT is that there is typically a healthy supply of miscellaneous, half-functioning equipment to mess around with. [Vittore] had an old laptop with a busted LCD sitting around (Google Translation), so he figured he might as well get it to do something useful. With a spare desktop LCD panel and some software tweaking, he built himself a slick network monitoring panel that hangs in his office.
He stripped the laptop down to the bare essentials, and mounted it along with an LCD screen in a plexiglass enclosure. He has Nagios running a server in his office, and with the help of a few plugins, he created a simple web interface that show him the topology of his entire network. The panel itself runs a live version of Debian, which he configured to load up his Nagios web page each time it is started.
While having the ability to view the status of every network-connected device in an instant is great, he didn’t stop there. While browsing around online, he found diagram for a simple USB-based performance monitor that uses a PIC to drive a pair of VU meters. He hooked the meters up to a router monitored by Nagios, so he can watch office’s bandwidth usage in real time.
If you’re interested in seeing how it was built, be sure to check out the Flickr photo set put together by [Vittore’s] co-worker [Matthew].
