  • Searching for that phrase brings up the Adafruit's sound board and I must say that this board has more features. Adafruit's board only has 2MB of storage compared to GB on this one depending on SD card. Adafruit's board only has 11 external triggers compared to 18 on this one.

  • Probably because an LED still needs voltage to turn on..

  • And yet this still hasn't been updated..

  • Current Rating? LM317 = 3A, 1N4001 = 1A, PTC = 0.5A? So, half an Amp?

  • For the same price, or maybe a little less, you can get a printer with twice the build volume. This printer incorporates old technology as well. It comes with 1 meter of filament?? You can't make anything with that! My printer came with 2 rolls of 1kg ABS..

    Sparkfun, I know this company probably gave a few printers just so you would sell it, but come on. It seems you are drifting away from what Sparkfun used to do. Sell components, not toys.

  • I think having complete kits is some what of a gamble. I think Sparkfun should have guides to building something. Like an arm, 4/6 wheeled robot, even up to a CNC frame. Sparkfun supplies most of the components to build these. Once you post online guides, you can go from there and supply a kit for the most popular one. This way, you don't risk too much. I can't believe I am telling a company this, but over the years seeing Sparkfun grow, I don't want to SF lose a dime. Sparkfun is a top contributor to the open source community and don't want to see that changed.

  • There is little ball bearings in a channel. But it doesn't move smoothly. The screw in the middle holding the halves together is metal on metal. I even put 3n1 oil on it and it still doesn't move smoothly. If you loosen the screw, it just makes the halves have play. This could have been better designed with an actual bearing, but for 7 bucks...

  • Wow, the “$50SAT” really has my imagination going. In 10 years, I bet hobbyists will start putting "equipment" into space. Just having a piece of hardware in orbit and to be able to communicate with it for getting common readings would be mind blowing. These common sensors could be temp, radiation, even searching the radio spectrum for little aliens! Add in a camera or even video and I would be in heaven. Ok, now I am going to start brain storming..

    I would highly agree with putting some 'spacecraft' parts up for sale. Nothing fancy, just something to give hobbyists a good start.

  • Need pull-up resistors on the I2C lines!

  • I really can't believe that no one has mentioned Opera.. Been using Opera for 5+ yrs now and is much faster than FF and IE (Which I used to DL FF). The only one I can't give an opinion on is Chrome. Tried it a few years back as after I downloaded it, started it for the first time (XP Pro), it crashed. Restarted, I did get to Google.com and it crashed again. Uninstalled and used Opera ever since. I do use Firefox as I do work and design websites and need to know if they work on FF. I really think that Opera could compete against IE and FF if people just tried it..
