Anadigi GPS-R02 DIY GPS Kit

Anadigi GPS-R02 DIY GPS Kit

I got this little “Anadigi GPS-R02 DIY” car gps kit from eBay seller anadigi-hk, and it was mailed direct from Hong Kong.

[Edit: Apparently, the eBay Store and user are no more.]

It came with the GPS Circuit board and a little plastic case for it, an MMCX antenna with magnetic base, and a matching USB cable. The mini-CD came with drivers and a few test and diagnostic programs.

It works great; by the time my computer comes out of hibernation, it already has a signal lock. Talk about bang for the buck!

The receiver is based on the NemeriX NJ1030A [Datasheet – Archive.org], and includes WAAS/EGNOS support.

Markings on the box: (They look like the vitals for the GPS Antenna)

  • Product Model: GPS
  • Center Frequency: 1575.42 +/-3Mhz
  • LNA Gain (Without Cable): 28dB
  • Noise Figure: <1.5dB
  • VSWR: <2.0
  • DC Current: 10mA Max
  • Mounting: Magnetic Base
  • Housing: Black
  • Working Temp: -40*C ~ +85*C
  • Vibration: Sine sweep lg(0-p) 10~50~10Hz each axis
  • Humidity: 95%-100%RH
  • Weatherproof: 100% Weatherproof
  • Cable Length: 3m
  • Voltage: 3-5V
  • Connector: MMCX
  • USB to Serial Converter (onboard): PL-2303* (but the Prolific Windows driver doesn’t like it, errors with Code 10: Cannot start”, according to the Prolific website, that means it’s likely a counterfeit PL-2303 chip. I’ll have to dig out the CD that came with it again.)

Update: How to add GPS to your Eee PC @ beta.ivancover.com – That’s definitely one of the first things I’d do with an Eee.

Ok, this 13″ Sharp TFT LCD screen with XGA (1024×768) resolution was used in some Dell and NEC laptops, including the Dell Latitude CPi D266XT.

The Dell Latitude’s screen and inverter has a connector to the motherboard consisting of 50 pins (25 x 2 pins)

Multi-colored Case Lights

Multi-colored Case Lights

Well, here’s the front of my recently-rennovated computer case. By ‘rennovated’, I mean “replaced old-and-boring blue LEDs with the multicolor color-changing LEDs of coolness.

How I managed this was to:

  1. Remove the front of my computer case. There were four screws holding it firmly in place. It then snapped out.
  2. Unplug the case wires that were plugged into the motherboard
  3. Remove lightbars, which were held in with faux-metallic brackets
  4. Replace LEDs with Color-Changing LEDs
  5. Test the LEDs, and seal it all up with electrical tape
  6. Reinstall lightbars and brakets, reinstall the front cover, and reconnect the wires.

:thumbsup:

See more about these fun little LEDs here. The case front has 4 LEDs in it, so each side has a top and a bottom LED, making some interesting colors in the middle. Even more interesting, the little airbubbles in the plastic lightbars glow two colors: one for the top, and one for the bottom.

2×16 Character LCD Display

2×16 Character LCD Display

Built with the PC Starter Kit (“LCD Kit 04”) from the good folks at 411 Technology Systems, it is mounted in a computer case spacer to be mounted in a computer.

You can buy LCDs along with the PC Starter Kit, which includes the parallel port kit and a CD with schematics, code, and other plans and goodies on it (“AN-CD-01”).

You can either purchase from their eBay Store or their Web Store (LCDs | Kits & Other Stuff)

And, they pack everything in baggies, and LCDs are put into ESD bags, and shipped in boxes so things don’t get dropped, crushed, smushed, etc. And yes, I’ve bought from them again and again, and I highly recommend them for LCD stuff.
