I love working on my own electronics projects in my spare time. I’m a true geek in that regard. Right now I’m working on a small GPS device using parts purchased from Sparkfun.

  • Product WIG-12005 | about 9 months ago

    I’ve been searching around the internet and can’t seem to find the schematics. I’m really interested in knowing what boost converter was used for the LCD.

    The LS013B4DN01 display this watch is using looks really cool until you realize it needs a 5V supply. Considering that everything else in your circuit probably uses a much lower voltage, you’ll need to boost your supply up to 5V to get this display to work. Most switched capacitor boost converters have an operating current that’s orders of magnitude higher than the display itself is using. For example, the LM2750-5 that the datasheet recommends has a typical operating current of 5mA. This means the boost converter is using over 800 times more current then the display itself! All of a sudden these displays don’t seem so low power anymore.

    Luckily Sharp has started to introduce Memory Displays that run on 3.3V, but this watch seems to be using the 5V version

    Ah great! Thank you.

    “What is the part number for the connector on this board?”

    “Is a datasheet avaiable?”

    Thanks…

    Hello? Anybody?

  • Product BOB-11570 | about a year ago

    What is the part number for the connector on this board? I’d like to find out more information on it. Is a datasheet available?

    I also built something like this using the Sparkfun Venus module. Check it out: http://youtu.be/Irvi9_ShTAk

    Errr… I hate April Fools Day. It jumped the shark years ago.

  • Product DEV-10329 | about 3 years ago

    Will it play Crysis?

  • Product WRL-00593 | about 3 years ago

    Does anyone know where I can find the suggested land pattern for this device?

No public wish lists :(
