How to make a nice pair of halogen bicycle headlamps using only materials available at Home Depot…a 20 watt low beam and a 50 watt high beam with MR16 Halogen Spot bulbs. Note: Floods don’t give you enough range at speed and you want to get the bulbs that have a flat piece of glass at the front. Thanks Jake! Link.
...put a couple FAQs and walk-through guides on the PSP so you could use it as a hand held reference when you are playing other game systems or if you are between PSP games. It makes things much easier now that you can read normal HTML text and image files instead of having to convert everything to an JPEG file. [via] Link.
Merging his interests in physical computing and electronic music, artist and composer Tristan Perich will give a presentation on his recent project, One Bit Music. Electronics programmed and packaged in a standard CD jewel case by Perich play minimal glitch/dance music when headphones are plugged in. The device is meant to fit into the standard album-based method of music distribution: you will find it along other CDs in a record store and it has different tracks; it will be released by Cantaloupe Music in the upcoming months.

A little while ago Lifehacker posted instruction how you could use Gmail’s SMTP server to send mail from any e-mail address. Drawback: Google would always rewrite your From: address back to your original Gmail address, kinda defeating our original idea. Last week then, Google added a new feature allowing Gmail users to add multiple e-mail addys and to choose one from a drop-down list when sending a message via the Gmail interface. What hasn’t been mentioned yet is that once you’ve added another verified e-mail address to your Gmail account, Gmail’s SMTP server would happily forward the new From: address! And this is how you do it… Link.

Have an old hard drive that no longer works? As long as it still spins up chances are you could build a clock out of your old hard drive! You will need some electronic knowledge, some common electronic components and a bit of patients. The clock that is produced isn’t exactly practical since most hard drives (especially older ones) are too loud for a clock that is to operate 24 hours a day. Thanks Doug! Link.
