    it's okay

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    this is very nice to have if you know how to solder. I have a couple of projects that need complicated resistor line-ups and it's nice to just solder the whole damn thing together and never having to set it up again.
    Cons:
    the solder doesn't stick to it very well. this could be due to my lack of skill but I think it's also because the holes aren't ...

    very nice module

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    I am very glad I bought this module. has two outputs: one is an analog output, which gives the sound level. for me it's around 50 when I don't make noise. when I clap, it's about 150 and when I shout directly into it it goes all the way to 1023. the other o...
    Cons:
    none that I know.

    pain to set up, good after that.

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    first of all, it's soooo cheap. also, as soon as you finally get it working (which might take some time) it actually gives pretty good detail. I can read from 10cm to 300cm, or something like that. I've placed mine on a servo so I can use it on my robot to ...
    Cons:
    no manual, and the internet will offer the wrong help at first. you should use the NEWPING library. I repeat... other libraries...

    very useful

    posted by Jumboman on 08/25/2013 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    This is very useful if you have a power-demanding arduino project. 9v batteries tend to run out fast, while this battery block can last much longer. plus, it's easier to use rechargeable batteries. the 2.1mm jack is already attached so you can't use it as a...
    Cons:
    doesn't have an on/off switch, which would be very useful.

    good breadboard

    posted by Jumboman on 08/25/2013 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

    Pros:
    I'm very glad I bought this breadboard. it's really big, twice the size of my old one, and so far all my projects have fitted on it just fine. it has 4 power lines on the side (both sides stop in the middle, didn't notice this at first) so you can easily us...
    Cons:
    none that I'm aware of. maybe I'd rather have a breadboard with mounting holes instead of the usual adhesive on the bottom.

    Works fine

    posted by Jumboman on 08/25/2013 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

    Pros:
    It works fine and it's very cheap. As soon as I hooked it up properly I could instantly begin sending and recieving data using my phone. You should check out some instructables on how to wire this properly. http://www.instructables.com/id/Success-Using-the-...
    Cons:
    No manual, no datasheet. Plus, the RX pin needs 3.3 volts so you need to build a voltage divider by placing it between a 1k and...
