    When you need more I/O for *duino

    posted by tnvd on 06/20/2013 Certified Owner

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

    Pros:
    Have you ever found the need for more input/output on your *duino? This is the item to complete your project. With this nice small board you can have 8 more inputs, outputs. This NXP (former Philips) chip has 8 quasi bi-directional ports via I2C. And an int...
    Cons:
    No documentation provided by DX, just surf the internet on pcf8574t. Price is rather high, can be cheaper.

    Perfect breadboard powersupply

    posted by tnvd on 06/20/2013 Certified Owner

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

    Pros:
    The board has two modes of power input. Through USB and through a DC barrel socket. There is a green LED to indicate the presence of power, and a latching switch to control the power to the board. Input voltage to be between 6.5~12V, or USB powered (5V). ...
    Cons:
    None.. O yeah, mine came with powerpins bend. And of course no documentation. DX : Get documentation online or a link.. don't...

    An excellent sensor

    posted by tnvd on 06/20/2013 Certified Owner

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

    Pros:
    This is such a nice sensor. The sensor itself has barometric pressure calibrated table. Also for temperature. Many sources on the internet on how to use and connect to for exaple *duino. I will be using this one in a growroom. Some plants does grow better w...
    Cons:
    None right now. I hope it will not fail on me.

    Good cables

    posted by tnvd on 06/20/2013 Certified Owner

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

    Pros:
    Well, what to mention about these cables? They do the job. If single cables are needed you can separate from this ribbon to have just one. Good quality connectors and solid mounted to the cable. Everybody who like to build with breadboard and/or *duino's ne...
    Cons:
    None I can think of right now

    Good small power source.

    posted by tnvd on 06/20/2013 Certified Owner

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

    Pros:
    Small compact power supply which delivers a rock solid, stable, 5V. There is a pot to fine-adjust the output voltage. The case has enough perforated holes to get it ventilated. The power transistors are mounted to solid aluminium heatsink which is part of t...
    Cons:
    Ai ai, here I have some cons. The heatsing was not 90 degrees towards the PCB where the powertransistors are soldered. So there...

    Cute to experiment with

    posted by tnvd on 06/20/2013 Certified Owner

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

    Pros:
    This is one of the fun items to use with your development board or in an actual application. There is enough information on the internet on how to connect, how to install light sensor, how to install temperature compensation for high ambient temperature. Al...
    Cons:
    Capacitors should be smaller (surface mount). Connector pins were very very bend. No documentation. Looking again on internet ...

    Red dot laser brick

    posted by tnvd on 06/20/2013 Certified Owner

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

    Pros:
    Good soldering. Nice to play with (after paying some attention to the wires and the brass piece) This is an laser led mounted on a small PCB. There are 3 pin connections which are not documented (I get used to the DX non documentation). So you have to figur...
    Cons:
    As usual; no documentation. Well wrapped, but the brass laser mount was creating shortcircuit to the blanc wires. The brass led...

    A must have for small setup/project

    posted by tnvd on 06/20/2013 Certified Owner

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

    Pros:
    Just use this small breadboard for a small projects or for grouping a part of the schematic aside to this breadboard as a general building block for next projects. That's the way I use it. Make the setup and use it over and over again. Good price and qualit...
    Cons:
    None I think of.

    One hell of a product

    posted by tnvd on 06/20/2013 Certified Owner

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

    Pros:
    So many input output over a i2c connection. Can even be daisy chained, but each board need its own select. For more info on the used chip and how to use with arduino, check this out: https://code.google.com/p/tm1638-library/wiki/Reference Anyhow, this is a...
    Cons:
    Mine 2 blocks of 7 segmet displays were not aligned to each other, so the looking angle was not correct. As for what the item i...

    A must for DIY breadboard

    posted by tnvd on 06/20/2013 Certified Owner

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

    Pros:
    Cheap. Handy for all breadboard users. Pins are already connected and are rather solid mounted. In nearby shop triple the price as at DX. I use them for Arduino, and Cortex prototyping development. Men cannot assemble these at the given price yourself. Just...
    Cons:
    The smell.. Hope it gets away. Some pins got loose from the cable after being used frequently (too much?). Other people mentio...
