    Great price and handy multi-voltage feature

    posted by gigamegawatts on 06/01/2013 Certified Owner

    Involvement:General (knows how to use it) - Ownership:1 week to 1 month

    Pros:
    This appears to be the real deal: works as expected for a BMP085 chip. This is the best price that I've seen for a BMP085 breakout board. The support for 3.3v is a very important for the increasingly common 3.3v platforms like the Raspberry Pi. 5v support...
    Cons:
    None

    Great quality, incredible price

    posted by gigamegawatts on 06/01/2013 Certified Owner

    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    Has all the features that I need for electronics projects: 3.3v and 5v outputs, USB output, on/off switch. Can switch between 3.3/5v/off independently on either end of the board Adds extra 4 ground and 4 voltage pins on topside of the board, making it usa...

    Feature-packed LCD with good software support

    posted by gigamegawatts on 05/26/2013 Certified Owner

    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    This is identical to the TFT01-2.4 LCD sold by ElecFreaks. You'll find tech specs and sample code on their web site. Compatible with the awesome UTFT library, with supports Arduinos, Chipkit (PIC) and some ARM processors. Specify the S6D1121 controller (...
    Cons:
    This is a 3.3V LCD, so if you plan to use it with a 5V platform like the Arduino you'll need to convert pins to 3.3V

    A Big Hat for Big Heads

    posted by gigamegawatts on 03/14/2013 Certified Owner

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

    Pros:
    This is a nice, roomy cap for people with big heads, like me. The front part of the hat is soft -- no plastic insert or mesh -- and the back has a long Velcro band. So, my head doesn't feel squeezed as it does in most baseball caps. Build quality is qu...
    Cons:
    It might be too big for people with small heads.

    Inexpensive drop-in replacement for DHT21

    posted by gigamegawatts on 02/18/2013 Certified Owner

    Involvement:General (knows how to use it) - Ownership:1 day to 1 week

    Pros:
    This is a drop-in replacement for the common DHT22 (aka RHT02) temperature/humidity sensor, but at half the price. I tried replacing a DHT21 in a sensor with this one, and the temperature and humidity readings are in-line with the DHT21. No downtime so fa...
    Cons:
    None really. The DHT21 is a fussy sensor to program, requiring nano-second timing, so it's not the best choice for all platfor...

    Works great for connecting 3.3V to 5V I2C data line

    posted by gigamegawatts on 02/18/2013 Certified Owner

    Involvement:General (knows how to use it) - Ownership:1 week to 1 month

    Pros:
    It works exactly as you would expect: connect 5V and GND to one side, 3.3V and GND to the other, and you can shift up to 4 bidirectional signals between 3.3V and 5. This adapter is a must-have if you're working with 3.3V boards like the Raspberry Pi. I've...
    Cons:
    None, really. For 4 bidirectional lines, the price is right.

    Great product for the price

    posted by gigamegawatts on 01/19/2013 Certified Owner

    Involvement:General (knows how to use it) - Ownership:1 week to 1 month

    Pros:
    This is, by far, the least expensive I2C LCD that I've found. It works as expected: you need just 2 pins to control the LCD, including the backlight. There are a number of available pinouts available for extending the product, such as adding 5V or Gnd pin...
    Cons:
    The mapping of LCD pins to I2C data pins isn't documented anywhere, and isn't compatible with existing Arduino I2C LCD librarie...
