Breadboard Power Supply Review

clip_image002[4]Alan Wang sent in this review of the breadboard power supply kit. We will be sending him the latest revision of the kit as a thank you for his review. If you are interested in the solderless breadboard kit this review may be useful for you.

The breadboard power supply: Useful and straight forward

You find your self in the middle of a busy week and you are asked by your teacher to build a circuit that can run off of any voltage between 3 and 12 volts DC and you can’t find a supply that will allow you just to pot the input and control the voltage. The solution: the bread board power supply. It’s a nice little board that allows you to choose your input and your output voltages and uses components that are readily and easily available from most electronics stores.

Let me start by saying that this is a great product for any one who works with electronics and can’t afford one of those expensive and or fancy power supplies that have displays and knobs for adjusting current and voltage. This board can do that and so much more in the long run.

The first thing I noticed about this board is that it allows the user to choose how much output voltage is actually supplied to components regardless the input voltage (which has a wide range and can be either AC or DC). This flexibility in allowing either an AC or DC input allows you to use either an old charger wall wart or even an old laptop power supply. Further more, you can attach a potentiometer into one of the output/input terminals and further control the supply voltage to the device being powered, for LEDs this means you can dim them or slightly (let me emphasize on slightly) overdrive them to see how they perform. Also, for those who like to be able to check for a working ground, the board includes a post to insert either a test lead or clip on a small alligator clip for testing. Apart from that, the board plugs right into your bread board without having to fumble with gator clips or other methods of connection. For those new to electronics, this board is a great aid in learning how to solder, read resistor values, and understand the markings on PC boards. Apart from its normal use as a bread board power supply, it can also be used for prototyping circuits that use LEDs and other low voltage / low current light sources. However, this board has also served as a replacement of a dead bench top power supply unit and I use it to tweak other current or voltage regulating circuitry. Any hobbyist or enthusiast interested in electronics should have one of these boards around in case you don’t have a power supply unit that is adjustable, or you are new to electronics and want a way to learn both some of the inner workings and how to solder. The board is ready in about three easy steps (okay, fine not really three, but really it is just three big steps to make the board); all you have to do is choose your resistor values, carefully solder everything and check connections, and then find a power supply to plug in (AC or DC) and enjoy the flexibility of the board.

    The kit is sold at Curious Invetnor

    So, it’s 2008. Where is the link to the actual product this review is talking about?

  3. Alan Wang says

    This review was intended only for the purpose of say someone who is new to electronics and it’s sole purpose is to point introduce people to this product and say some basics about the board, not review it in a fully technical sense(the technical review is to come, since I haven’t quite gotten the kit together yet (working on it as we speak).

    I don’t think so. Averyone is proud when releasing a new homemade device, so you have your own website and you must promote it. Isn’t for the taste of all, but i understand that you are proud and i like it, waiting for more goods like this.

    Keep on the good work and regards from spain!

    Perhaps you are right. This was submitted as a review so I posted it as such. I am proud of my first kit design. Maybe I was a bit too happy receiving positive feedback and wanted to share it. I will consider removing this post.

    Does anyone else think it was bad taste to post this article?

  6. Thomas says

    Hmmm, how should I say? I don’t consider this a serious review. To many marketing phrases, no technical information.

    I think I don’t want to read a website with such articles.
