Simple Pop-up Notifications

September 3, 2009 by 24 Comments

simple_linux_notifications

[Kristofer] shares a tip on a simple way to add pop-up notifications to Linux scripts. The package libnotify allows you to use the command “notify-send” to pop up a message when you need it. The syntax is simple enough, just place your message in quotes after the command like so:

notify-send "Go read hackaday.com"

There are a lot of other options that go along with this command such as adding an icon and setting how long the message will be displayed. This would be great for projects that interface through scripts, displaying messages as events happen. For Ubuntu, installing this package was as simple as “sudo apt-get install libnotify-bin”.

Tired of making kindergarten macaroni art PCBs? Check your Gerber files before you send them off to a fab house with a Gerber file viewer. Viewplot , GerbTool’s Viewer , and FAB 3000 Free DFM are all free versions of for-pay software to view your Gerber files. If you use Windows and demo software, these are nice options. If not, you can use gerbv. Allied with gEDA, Gerbv is free, open source software that you can use to view all of your RS-274X Gerber files and Excellon-type drill files. Still being worked on with an active development group, gerbv does not have all the bells and whistles, it does have the ability to delete objects. Check it out after the break.

Ubuntu 9.04 On Kindle 2

[digg=http://digg.com/linux_unix/Ubuntu_Jaunty_on_Amazon_s_Kindle_2]Having read books on a Palm device for years we were excited when Amazon came up with the Kindle. Our problem is that if you’re going to carry around a portable device it should do a whole lot more than just display text from a few books. [Jesse Vincent] managed to get Ubuntu 9.04 Jaunty Jackalope running on the Kindle 2. This opens up endless possibilities to run whatever you want on this hardware.

The new functionality was presented in a talk at OSCON 2009. Be warned, [Jesse] has a very high geeky-hacker level. Make sure you have a tech dictionary and Google at the ready when you watch the video embedded after the break. His talk starts at about two minutes in and runs for five minutes total.

Guitar Hero Strum Bar As Guitar Kill Switch

September 3, 2009 by 20 Comments

guitar_hero_killswitch

[Ray] had a Guitar Hero controller for PlayStation 2 sitting around. Because he moved on to playing the game on Xbox 360, he decided to cannibalize the older controller for its parts. He removed the strum bar and fit it inside of a mid-1980’s Peavy Patriot electric guitar. Once wired up, it works as a kill switch; it stops all sound from making it to the amp whenever the strum bar switch is actuated. Don’t miss hearing this effect in the video after the break and keep sending in those Guitar Hero mods. Continue reading “Guitar Hero Strum Bar As Guitar Kill Switch” →

Single Tube Nixie Clock

This single tube nixie clock cought our eye today. After receiving an IN-8 tube from a friend, [Trax] wanted to find some project to show it off.  He decided on an art piece that doubles as a clock. Tastefully mounted in a simple wooden box with a pretty inlay, the tube is lit from below with a green LED that pulses every second. A single button, located on the back, out of view is pressed to request the time. You can see the time being displayed on the video above. To see the guts and read about how he’s using the PIC16F84’s built in clock to keep track of time, check out his site. Even though this is a Nixie, it reminds us of the Decatron kitchen timer we saw recently.

Neo-Geo Case Mod

Neodrive%20with%20pads

What do you get when you cross a Neo-Geo and a Sega Genesis? A pretty vintage case mod. [Brett] used a variation of the 16-bit console (known as the Mega Drive II) as the base of his project. With an original Neo-Geo motherboard and a few other components (such as a power indicating LED), the ‘Geosis’ was born. [Brett] removed a few of the unnecessary parts from the mobo, like the power-amp, and set it up to work with a regular 5V DC wall adapter. The PCB also had to be clipped so it would fit into the Mega Drive chassis.

Though it may not be the case, some Neo-Geo motherboards in circulation have been salvaged from arcade machines. An enclosure would be essential for protecting them during standalone use – something [Brett] plans to do a lot.
