Geek on the Cheap #114:
Five Great Gifts for Under $20

Sunday, November 29th, 2009

I’m already sick of the whole shopping thing and yet every night lately I find myself trolling around the web looking for bargains. And there’s so much to buy — so many options, so many reviews to peruse.  Ugghh.

And yet…

Some geek demon is compelling me to offer you more to ponder. Instead of a long list, however, below are just five gifts for under $20. Just five? Yes, except each gift is offered on a unique website that I think you’ll find interesting.

Holiday Decorations
3D Christmas Tree Kit ($12.95) / LED Menorah ($10.00 / $14.00)
website: Maker SHED

Toys
6-in-1 Educational Solar Robotic Kit ($17.88)

Home

website: ThinkGeek

Head & Heart

Be prepared! Each one of these websites has many more gifts to offer. Got a Secret Santa or Yankee Swap coming up at work? You’ll be covered. Five more next week…

How to Fool a Phantom Limb

Sunday, November 22nd, 2009

Thanksgiving is this Thursday in the U.S. and I’m looking forward to eating platefuls of turkey, squash, stuffing and whatever else catches my eyes-too-big-for-my-stomach. But I want to give you something else to sink your teeth into, fellow Americans (and you others around the world who will not be gorging yourselves). Here is some delicious food for thought.

V.S. Ramachandran is a neurologist at the University of California, San Diego (director of the Center for Brain and Cognition; professor with the Psychology Dept. and Neurosciences Program; and adjunct professor of Biology at the Salk Institute). Although all these titles may lead you to the swift conclusion that any talk he gives would be boring and jargon-filled – incomprehensible without the benefit of a PhD/MD — Ramachandran is actually quite funny. And he has the ability, like Oliver Sacks, to describe the inner workings of the brain through clever example.

But why is he a geek on the cheap? Because in trying understand phantom limb syndrome, he came up with a $3 therapy that works — a mirror box. A simple cardboard box with a mirror in the middle. This was instead of trying to create a virtual reality for an amputee, which would cost millions of dollars. Ramachandran’s therapy is now used routinely at Walter Reed Army Medical Center on soldier amputees.

Brilliant, funny and cheap. That’s my kind of geek.

For more fascinating lectures, be sure to check out TED.com, “riveting talks by remarkable people, free to the world.” It’s an incredible resource and, as they say in their tag, it’s free.

“Seven Essential Free Software Apps” at CNET

CNET video - Seven essential free software apps

This week I was going to give you tips on selling or recycling your old tech to make way for your holiday-gift tech. I was going to recommend you sell your stuff on eBay and Craigslist, that you make sure to archive all your data (to DVD or another hard drive) and then wipe your hard drive clean using a free download such as Eraser or Active@ Kill Disk.

But when I went to CNET to get the download links, I saw a great, short video on “Seven Essential Free Software Apps.” These are seven free apps to load on your new computer instead of all the crap that was on the old one.

Below are links to the seven apps mentioned (the ones with stars are those I already use and also recommend):

  1. Virus protection: AVG Anti-Virus*
  2. Browser/Email: Firefox*/Thunderbird
  3. Instant Messenger: Pidgen [Windows]; Adium [Mac] (I don’t IM)
  4. Instead of MS Office: Open Office* (I use MS Office for work)
  5. Video/Audio Player: VLC Media Player*
  6. Graphics Editor: Paint.net [Windows]; Skitch or Seashore [Mac]
  7. Security: Hijack This (I prefer Ad Aware)

This software will keep your wallet fat and your computer nimble. What more could you ask for?

The Holidays Are Creeping Up

Monday, November 9th, 2009


Yes, it was just Halloween but Hanukkah/Xmas/Kwanzaa (in order of appearance) are just around the corner. So here are three DIY projects to get started on, in order of difficulty (though none of them is truly difficult). Two of them require a minimal amount of sewing and one involves duct tape. Take your pick:

Cellphone Beanbag Chair
ThinkGeek customer photo of cellphone beanbag chairWhy does your cellphone need a beanbag chair? Because it needs to relax after getting poked all day by somebody’s gigantic meaty fingertips. Never made a beanbag before? It’s easy: 1) cut out 2 circles of fabric, 10 inches in diameter each; 2) put the “right” sides (the sides you want to show) of the fabric facing each other and sew the edges together, except for about 2 inches; 3) turn the fabric rightside out; 4) pour in dried beans until the bag is about 75% full; 5) stitch up that 2-inch hole. Now if this is too much work for you, ThinkGeek is selling them for a mere $9.99. Be sure to check out the customer action shots. Those are some happy, relaxing devices.

RFID-Blocking Wallet
What’s RFID and why do you want to block it? RFID is radio frequency identification — the technology used to tag and track animals in the wild. It’s also used in some credit cards, many corporate IDs, and in U.S. and Euro passports. Why should you care? Because an RFID can be hacked with $8 worth of gear. So for $8, a thief can steal your credit card name and number or any other information stored in your RFID-enabled card. Or weirder yet, your movement could be tracked if someone wanted to know where you were.

RFID-blocking walletBut with a little aluminum foil and duct tape, you can make your own RFID-blocking wallet. Yes, I know, this sounds suspiciously crazy, as though I’m telling you aliens are reading your brain waves — beware! But RFID isn’t alien; in fact it’s pretty simple technology. And the ease with which it can be hacked is well known. In fact, there are RFID-blocking wallets and cardholders on sale at Amazon for as little as $14.39. But wouldn’t it be more fun to Macgyver your own? (My husband wants one of these.)

Touchscreen Gloves
Touchscreen glovesIt’s getting cold here in Vermont, which means I’ve switched from my zip-up fingerless driving gloves to my boring-but-vastly-warmer fleece-lined gloves. This also means that in order to use a device with a capacitive touchscreen, such as my iPod Touch, I need to take off said fleece-lined gloves. Brrrrr. Instead, I would prefer to be able to control my device with those toasty gloves still on my hands. And no, I don’t want sew some funky fingerhoods on fingerless gloves and have to fool with them every time I want to poke my device. What to do?

Easy fix. Sew patches of conductive thread on the tips of your gloves. This allows the conductive property of your fingertips/thumbtips to reach your device. I must admit, this is my favorite project of the three here and I will soon be updating all my winter gloves. You can find full instructions at GirlieGirl Army. And yes, you clever cheap geek, conductive thread is not cheap compared to everyday cotton thread. But there are many fun things you can do with conductive thread. For example, you could mod gloves for your friends, make a robot t-shirt with LED eyes or create a winter hat that lights up from front to back. To see more projects, go to Instructables.
