Playing Doom on the Raspberry Pi

The Raspberry Pi created quite the buzz on the internet prior to its release. Much like the rest of the electronics community, we here at SparkFun couldn't wait to get our hands on one. Well, we finally had the opportunity to do just that. The Raspberry Pi, "An ARM GNU/Linux Box for…

How to Power a Project

February 7th, 2013

A tutorial to help figure out the power requirements of your project.
  • Product WIG-12000 | about 3 weeks ago

    The board can not be powered over FTDI without first soldering the 5V jumper that’s near the speaker +- connections. If you power it this way, don’t power it from a barrel jack at the same time. Try this and see if your board starts working correctly. If so, you might have a problem with the power supply that you’ve been connecting to the barrel jack. Also, make sure that your power supply outputs between 6-15V and can output at least 300 mA to be on the safeside.

    They are built into the PCB itself. Take a look at this picture.

  • Product KIT-11607 | last month

    I’m still hoping/planning to get bluetooth working with this kit. There are a few technical hurdles I have to jump first however I do think it’s doable.

  • Product KIT-11607 | last month

    The original IOIO board was not a poor seller. It was only retired because the IOIO-OTG was the next version and a substantial upgrade to the original.

  • Product KIT-11607 | last month

    I don’t have a definitive answer on this at the moment. This kit was designed and built around the IOIO-OTG. The original IOIO has been retired for at least a year now and I currently don’t have one to test with. If it does work, I’m sure you have to at least upgrade to the latest firmware.

  • Product KIT-11835 | last month

    Yes, if you help them with the soldering, they can play music with the board without programming (it comes pre-programmed). By default, you can use the blue potentiometer to select between three octaves.

  • Product WIG-12000 | about 2 months ago

    Yes, if you’re using a microcontroller, you can have it trigger songs on two boards at the same time (well technically a few microseconds apart). I don’t know what you mean by 4 outputs though, 4 boards?

  • Product BOB-10653 | about 2 months ago

    Awesome work! Wish the best for you and your brother!

  • Product WIG-12000 | about 2 months ago

    They can be connected directly since the pins are 5V tolerant.

  • Product WIG-12000 | about 2 months ago

    I don’t have an example Arduino sketch for this purpose but the WavTrigger’s home site has a section about the serial commands for controlling the board. You will essentially use the serial library of the Arduino to send a command (a sequence of bytes) to the WavTrigger as well as receive information back.

    Yes, you can directly connect Tx/Rx of the Arduino to Rx/Tx of the WavTrigger. Make sure you connect GND as well.

No public wish lists :(
