How to Make Your N800 Click

14_16_19060108 If you’re a new Nokia N800 owner, then you might have noticed a glaring omission in the supplied software: there is no camera app. Sure, you have the webcam option when you launch the Nokia Internet Call communication program, but you can’t take any photos with it. Owners who long for a portable pic from their Internet Tablet, just have to download and install the Noika Camera from the online software catalog. With a Wi-Fi connection established:

  1. Browse. Open Tools > Application Manager and click “Browse installable applications.” Select “All” entries from the Nokia online catalog.
  2. Install. Find the Camera application and click “Install.” The Camera app is installed inside a new folder, “Extras.”
  3. Launch. Open Extras > Camera and start the app before you extend the camera. Now pop out the camera and click a pic. Don’t set your expectations too high, though. The resulting images are 640x480 with a file size of approximately 250Kb—very poor quality.

If you’re more of a DIYer, then you can roll your own camera app using the Nokia Camera API. You might want to study the image quality from Nokia’s Camera app first, however, then you’ll know whether or not your bit-bustin’ efforts will be worthwhile.—Dave Prochnow

Update: The (Former $250) NOW $120 DOS Tablet PC

Hp_usb_disk In May 2007, we published a project on Instructables that showed how to assemble a potentially useful tablet PC. Why was this project only a potential success? We couldn’t get the Fujitsu Stylistic 1000 to boot. All of that has changed and now we can boot the Tablet PC in DOS, Windows 95, and DSL Linux. The secret element that made this doorstop into a viable Tablet PC was a Windows tool called HP USB Disk Storage Format Tool V. 2.1.8. At the link, a Texan named Nox will supply all of the needed know-how for using this utility, as well as downloads for both HP USB Disk Storage Format Tool and a collection of boot files. Now don’t get too excited, these dated tablet PCs only worked really well when they were booted into DOS. So we converted ours into a dedicated DOS game machine. Skip the stylus and use an old salvaged PS/2 keyboard. Also, drop the battery and pick up a power supply. These two mods to our original project will shave about $135 off the project’s price tag. Not bad for around $120.—Dave Prochnow

Briefly Noted: Add 3G to an Eee PC

Img_0741

JKKMobile is expanding his bag of Eee PC tricks. The newest addition to his repertoire is grafting a 3G modem complete with SIM card inside his ASUS Eee PC. Both video and a set of sorta step-by-step images will help guide you through the process. Have you hacked your Eee PC, yet? If so, please post your project in our comments section.—Dave Prochnow

Happy Easter (Eggs), Kindle

Kindle_gps Just what every Kindle owner needs, a fistful of Easter Eggs for activating Google Maps GPS CDMA, a screenshot grabber, clock, fonts list, picture viewer, Minesweeper game, and diagnostic commands. All of these wonderful gifts thanks to the exacting reverse engineering efforts of Igor Skochinsky. The basic process for enabling one of these Easter eggs follows this type of scenario:

  • Inside the browser
  • Press Alt + 1 (one)
  • Google Maps will now display your current location
  • Press Alt + 2 for a display of the nearest gas stations
  • Press Alt + 3 for a display of the nearest restaurants

Skochinsky has thoroughly documented his efforts at unearthing all of the Kindle’s secrets in his Reversing Everything Blog. Watch our site in the future as we explore more Kindle hacks.—Dave Prochnow

How to Make a Fuel Cell-Powered Car

Opener What looks like a refugee from Mad Max is really a modified RC car that runs on water rather than conventional batteries. This proof of concept project gives you some practical meaningful experience using a fuel cell to generate usable electricity. Why wait for the Honda FCX Hydrogen Car when you can build your own working model prototype today?—Dave Prochnow


TIME: 7 HOURS
DIFFICULTY: AVERAGE DIFFICULTY
COST: $132.23


PARTS

  • 1:32 scale RC Hummer (RadioShack #60-250; $9.99)
  • Double reversible fuel cell Fuel Cell Store #1158-7110301; $67.50)
  • 30ml gas storage cylinders (Fuel Cell Store #1172-7110307; $7.50)
  • (2) Clamps (Fuel Cell Store #1174-623002; $1.85)
  • 24” silicon tubing (Fuel Cell Store #1176-7110309; $3.25)
  • Syringe (Fuel Cell Store #803-620600; $1.50)
  • 5V DC to DC step up (Spark Fun Electronics # PRT-08290; $9.95)

MISC.

  • 3V solar panel (Fuel Cell Store #951-621500; $20.50)
  • (6) 2mm Banana Connectors (Mouser #565-5936-0; $0.70)
  • Hookup wire 22-gauge (RadioShack #278-1224; $5.99)
  • Distilled water (local grocery store; $2.00)

NOTE: All fuel cell parts can be ordered from the Fuel Cell Store. Links for the exact parts are currently unavailable.

STEP-BY-STEP

Step1 1. Convert the RC Hummer from battery power to fuel cell power. Install the 5V DC to DC step up circuit with the PCB modified for 3.3V output. Connect a pair of 2mm banana connectors to the input terminals of the DC to DC step up PCB. Connect the PCBs output to the positive (+) and negative (-) terminals of the Hummer’s battery box.


Step2 2. Fill the gas storage cylinders with distilled water. Attach two 6-inch lengths of silicon tubing to the cylinders. Plug the other end of the hydrogen cylinder tubing into one of the tube stubs on the black terminal side of the fuel cell. Plug the other end of the oxygen cylinder tubing into one of the tube stubs on the red terminal side of the fuel cell. Attach two 2-inch lengths of tubing to the two remaining hydrogen side and oxygen side tube stubs.


Step3 3. Fill the fuel cell with water by drawing water out of the 2-inch tubing with the syringe. Repeat this process on both the hydrogen side and oxygen side of the fuel cell. Seal these short lengths with two clamps.


Step4 4. Connect the solar panel’s positive (+) terminal to the red, oxygen side of the fuel cell. Connect the solar panel’s negative (-) terminal to the black hydrogen side of the fuel cell. Place the solar panel in bright direct sunlight. The fuel cell will begin to produce both hydrogen and oxygen by electrolysis. In a low winter sun, this gas production process can take approximately 30 minutes to fill the two 30ml cylinders.


Step5 5. When the cylinders are full of gas, disconnect the solar panel from the fuel cell. Connect the 5V DC to DC step up input to the positive (+) and negative (-) terminals of the fuel cell. The fuel cell will produce a rock solid 2.2V of electricity.


End 6. Switch on the Hummer and drive around. You should expect about 12 minutes worth of driving from 30ml of hydrogen/oxygen. When the gas is depleted, return to the “gas pump” in Step 4 and disconnect the Hummer and reconnect the solar panel for beginning the electrolysis process all over again.

Join the Robotic Football League

Lineup Are you ready for some football? Robot football, that is. Well, let these bots do the gridiron game for you. Join the Robotic Football League (RFL). Founded in Westminister, Colorado by Active Innovations, this new sport brings teams of robots to a competitive field for some football. These aren’t just any kludged together robots, either. The players in this league are derived from the AI-O1 robot built by Active Innovations. Featuring wireless communications, a PIC microcontroller, and built-in voice, the AI-01 can be configured as a passer, receiver, and blocker. The $119 robot can also be hacked into a “dream player” with a $19.95 RFL USB to AI Adapter from SparkFun Electronics. Designed for 2-bot, 3-bot, and 6-bot rosters, the RFL could be coming to an open 8-x16-foot floor or HobbyTown USA near you.—Dave Prochnow

Update: Download SIP-VoIP for iPod touch

Countdown_timer As we mentioned earlier, iPod Touch Mods has a project for adding a microphone/preamp to your iPod touch. Coming on New Year’s Day 2008, you will be able to download the SIP-VoIP software that will add voice-calling capability to your iconic Apple MP3 player. More than just good cheer is at work here, so donations are being solicited.—Dave Prochnow

Hack an iPod touch Into an iVoIPhone Type Thingie

Ipodtouch_mic Didya tell Santa to slip a brand new shiny Apple iPod touch under the tree fer ya this year? Good, because now you can head over to iPod Touch Mods for a somewhat cryptic project for adding an input microphone/preamp (neatly embedded inside a dock connector) to your new fangled Web-enabled MP3 player. Once you’ve mastered that technological feat, you can try to look up the enterprising hacks of eok for adding VoIP to your iPod touch w/microphone. With a little luck, you could have your 16Gb iVoIPhone ready for Macworld Conference & Expo San Francisco 2008 and scoop Apple on its own “one more thing” announcement.—Dave Prochnow
