How-To: Make an RGB combination door lock (Part 1)


Part 2 can be found here

Putting a custom designed electronic lock on your space seems like a geek right of passage. For our latest workspace, we decided to skip the boring numbered keypad and build a custom RGB backlit keypad powered by an Arduino. Instead of typing in numbers, your password is a unique set of colors. In today’s How-To, we’ll show you how to build your own and give you the code to make it all work.

How-To: Super simple serial terminal

This hack shows how to make a dumb terminal out of a keyboard, LCD screen, and an 8-bit microcontroller. From time to time, a portable dumb terminal can be handy for when you have to rescue a headless server that’s acting up or if you are building a minicomputer out of a WRT, or if you just want to learn how to run a keyboard and LCD screen with a microcontroller. This super simple serial terminal will use RS-232 to control a headless linux system. Additionally, you might want to check into some of the command line interface programs that allow web browsing, AIM and IRC chatting and more directly from the terminal, but nothing beats being able to track your pizzas with this device.

The Linux system in question here will be Linux Mint. It’s a young distro based on Ubuntu that’s gaining a lot of attention lately, though the principles can be used for other Linux distros.

iPhone eve’ extra


The guys at I-hacked put up a how-to on giving your windows mobile phone some iPhone skinned powers, but later in the day they decided to make it login required. Thanks to [Katrina] for the tip. (requiring logins for contributed content just doesn’t sit well with me.)

[chris] sent in his own round up of his personal projects.

[Chris Coleman] let me know about hacktherazr. They’ve got some decent guides on customizing just about everything on the things.

[Ben Heck] got sick of emails, so he’s offering to build one more xbox 360 laptop, if you give him a pile of money.

Staring sunday, I’ll be ripping the hell out of my new house (and re-doing most of the upstairs). Do me a favor and keep the tips line brimming over.

[David] has some interesting ideas involving wireless AP antennas and wireless keyboards. How about a cantenna…
