Computer That Sent First Email 40-Years Ago

| October 31, 2009 | 0 Comments

What you’re looking at above is the computer that sent the very first email via ARPANET, 40-years ago on October 29, 1969. Simply put, ‘the message was sent from the UCLA SDS Sigma 7 Host computer to the SRI SDS 940 Host computer.’ Click here for first picture in gallery.

Like most systems of the era, the latter machine had a tiny core memory allowing between 16 and 64 kilowords.

Top 10 DIY Projects for an Extra Day Off

| September 7, 2009 | 0 Comments

It’s the last day of an unusually long weekend, and there’s absolutely nothing on the schedule. Break out the tools and pull up one of these nifty DIY projects to improve your living space and boost your can-do cred.

10. Light up your yard with mason jars

Buy a mess of ground-staked, solar or battery-powered yard lights from your local big box store, and people might be impressed at your ability to space the sticks you plunge into the ground. Convert some run-of-the-mill mason jars into hanging votive lanterns, battery-powered backyard lights, or go the way of weekend editor Jason and make your own solar-powered sun jars, and you’ll get some real kudos, and have a nicer looking yard, to boot.

9. Make your patio a Wi-Fi hotspot

Three different solutions of varying DIY-ness can get your Wi-Fi out to your grassier spaces. A self-powered solar extender is the ultimate in techno/eco-cred. If that kind of cost, soldering, and circuit knowledge is a stretch too far, you can install DD-WRT or boost your household router with Tomato to boost its signal strength and, in the case of DD-WRT, turn an old or spare router into a dedicated repeater. That still involves a bit of installing, though, so for a casual shot at backyard Wi-Fi, try a tinfoil parabola, a wok-style strainer, or a dollar’s worth of extender parts.

8. Build a backyard pizza oven

If you’ve had wood-fired pizza before, you know it’s notably different and tasty, and almost always pricey. You can have the good stuff whenever you feel like building a fire, however, with two different Lifehacker readers’ brick-by-brick instructions. Kevin Lester showed us his fourth pizza oven build, while Mike Wilkie based his two-level oven on Forno Bravo’s extensive wood-fired guide. You can do the same, and become the grill party invitation nobody turns down.

7. Assemble an outdoor movie theater

Your couch can only seat so many people. Your yard or patio, however, can fit as many folks as feel comfortable, and offers a much nicer environment to eat, drink, watch, and enjoy the waning bits of summer air, whether for the kids or with friends. Wired.com has hit upon this project twice, once with a house-mounted sheet and DVD/projector. Then the Geek Dad tackled the idea with a stand-alone outdoor screen, built with PVC pipe, mounted in cement, and ready for easy setup and take-down. You’ll need a decent projector for either setup, but often times, nobody at work minds if the presentation room is a little de-stocked on weekends.

6. Power up your Wii

You can’t pull off the total renovation that you can with an XBox Media Center, but your Wii can do a lot more than let you play tennis against the in-laws. You can surf the web with the recently-made-free Opera browser, and once that’s installed, a free Orb software package lets you use your Wii as a media center. These days, opening your Wii to the Homebrew channel doesn’t even require the purchase of an (admittedly great) Twilight Princess game and extensive hacking, and once that’s done, you can back up and load games from a hard drive, play old-school games in an emulator, and much more.

5. Build yourself a serious knife block

Two or three good, sharp knives are really all you need, but you’ve probably got more than that. If you bought them piece by piece, or don’t want to shell out for a generic hunk of wood, consider making your own wall-mounted magnetic holder for easy access and visual appeal, or cut a holder out of a counter for super-quick access. We’re also partial to Chris DiClerico’s DIY universal knife block, which requires only a few bucks of wood, dollar store bamboo skewers, and access to a table saw.

4. Get creative with enhanced paints

Go beyond the color spread at your local paint store, and you’ll likely find a good deal of neat paints that can inspire some awesome projects. Dry-erase or ‘whiteboard’ paint lets you jot down your ideas anywhere, and that inspired reader Chris Burke to make this awesome wall-size speech ‘bubble’. He also layered some magnetic paint underneath, the kind that lets you hang posters without nails or tacks. If school-style chalkboards are more your speed, you can grab a bucket of chalkboard paint, or make your own, and then craft an erase-as-you-go wall calendar, kid-friendly table, or wall mural (sorry, original link is apparently dead). If they made tinfoil-based Wi-Fi boosting paint, we’d simply declare the whole house in need of a new look.

3. Fold and cut your own furniture

You only occasionally need an extra seat or two for groups of guests, or maybe you just need a cheap place to sit when working in the garage. The Evil Mad Scientist blog suggests buying a few sheets of paperboard or plywood and crafting some flat-packing but sturdy stools. If it’s little ones you’re looking to seat, and entertain while you do so, the FoldSchool tutorial site details how to help kids make their own stepladders, creative kids table seats, and much more.

2. Add rope lights for cheap ambient improvements

Gina’s father-in-law used rope lights (and a nifty reverse circuit switch) to craft an automatic pantry light system. Jason added an eye-pleasing and light-improving touch to his extreme home office makeover with strategic rope lights. Other crafty folks have found rope lighting useful for kitchen looks and ridiculously awesome home theater setups. It’s inspiring, illuminating stuff, and fairly easy to get started with.

1. Spruce up a bare wall

Not every notably blank wall in your dwelling requires custom-framed artwork or expensive prints. Gina combined her Flickr account and a few dollars of craft store hardware to craft a sleek wire photo wall, inspired by this wood block example (original link down). Adam found his inspiration in used record stores and great album art, crafting an album art wall on the cheap. If great-looking books are what you want to show off, you can get by with very little by converting a colored wire hanger.

Notable and Crazy Sony Cassette Walkman Editions

| July 1, 2009 | 0 Comments

Sony’s cassette tape Walkman came to life in many shapes and forms through the years. Here are a few of the great, the important and sometimes plain weird Walkman models.


The original TPS-L2 Walkman went on sale 30 years ago today, July 1st 1979, in Japan. It played stereo and had dual mini headphone jacks for sharing audio with a friend. There was a mic, but it was not used for recording, but to output your voice to your buddy’s headset so he could hear you over the music. The press received it in a lukewarm fashion, but the device took off thanks to celebrity product placement.


The 1981 WM-2 is the first attempt at making a Walkman so small, its only slightly bigger than the tape.

Brian May’s homemade guitar

| June 26, 2009 | 0 Comments

Seven Sexton sent us a link to this awesome 1992 video of Queen‘s Brian May talking about “The Fireplace,” his famous electric guitar that he and his dad built from scrap bits such as a mantle from a 100-year old fireplace (hence the name), a chunk of a table, a spring from a motorcycle, a piece from his mother’s knitting needle, etc. Amazingly, this is not some fragile relic he keeps in the closet, but a working guitar, one you’ve heard on many Queen songs. His family was poor and his dad built most of their home electronics, including their television and radio. Wonderful, inspiring little piece. I love the opening quote from him:

I’m still a kid. Basically, I LOVE the sound of the guitar. I love making it. I love standing there and making that noise.

Plantronics DSP 500 Headset

| October 23, 2008 | 1 Comment

Intensify your computer digital audio experience. The DSP-500 is perfect for multimedia applications including games, CDs and MP3 music, speech recognition and voice applications.

For me, MAC OS X immediately detected the USB device as a DSP sound processor and the headset was ready to use in a matter of seconds. As far as the headset is concerned, the Plantronics DSP-500 comes with a high quality lightweight headset with a 3 meter long cord, which has a rather modest sized DSP and an in-line volume control attached to it. The 3-inch long attachment is the Digital signal processing unit, which houses all the works that processes sound and sends it directly to the headset.

I use a Plantronics DSP-500 USB Headset for most of my calls using Skype. I am now doing 50% of my calls on Ustream.tv using this headset and Skype people tell me quality is great.

The quality is much better than a cell phone or a landline. It has some amazing DSP noise-canceling technologies.

As far as PC audio is concerned, the DSP-500 is Plantronics’ top of the line offering.
