It might be interesting to note that the most important electrical component on a power supply is the capacitor. I personally recommend buying a power supply equipped with a Nippon Chemi-Con capacitor.
The power supply market is rapidly changing in terms of application needs, particularly in the last couple of years. According to Jameco's power supply sales expert, David Lofstrom, the industry trend is leaning towards the growing LED power supply market.
Therefore, in this blog we are reviewing an LED power supply from Mean Well USA, Inc., a company that sells power supplies under its own brand. The ELN-60 seriescomes in six different voltages: 9V, 12V, 15V, 24V, 27V, and 48V, with the most common being the 12V. The specs of the models differ in the potential output on the rails of the higher voltage units. The total output power of the 12V rail is 60W, which is more than enough for the average LED-user to exceed.
Specifications for the ELN-60-12V:
|DC Voltage (V)||12|
|LED Operation Voltage (V)||6 ~ 12|
|Rated Current (A)||5|
|Current Range (A)||0 ~ 5|
|Rated Power (W)||60|
There are many areas where voice recognition can be extremely useful, such as voice-controlled entry systems, automated house applications, and voice-activated vehicles. The main difference between speech recognition and voice recognition is that voice recognition products, such as the Say It Module, generally only have to deal with a limited vocabulary.
When you speak into this module, it will match your words to a set of predefined commands. Once the module has determined if there is a match, it will then act on a defined command, such as the movement of a robot. Although the module comes built-in with 23 predefined (or speaker independent) commands, users can create up to 32 user-definable (or speaker dependent) commands. You can begin by testing the words that are already programmed in the module, which are grouped under Trigger and three Wordsets as shown below:
Built-In Speaker Independent Commands:
|Trigger (0)||Wordset (1)||Wordset (2)||Wordset (3)|
|0 – robot||0 – action||0 – left||0 – zero|
|1 – move||1 – right||1 – one|
|2 – turn||2 – up||2 – two|
|3 – run||3 – down||3 – three|
|4 – look||4 – forward||4 – four|
|5 – attack||5 – backward||5 – five|
|6 – stop||6 – six|
|7 – hello||7 – seven|
|8 – eight|
|9 – nine|
|10 – ten|
As far as using the graphical user interface (GUI) to test the predefined commands, when the red LED indicator light on the module and the software window prompt you to speak, you must speak clearly and directly into the microphone on the module. If the module understands, you will see the command highlighted in green on your computer screen. You can continue testing in this manner with all of the words. If the module does not recognize the word or there is nothing said, an error message window will pop-up. This will come in handy when you want to test any new commands.
The 10-pin header makes the module breadboard friendly, and is designed to fit in one row on the Board of Education and Boe-Bot Robots.
The current product line will blow you away. This Arndt Electronics unit features a 120mm x 120mm fan. The 5-speed variable fan control kit with LCD display and power supply is the top-of-the-line Arndt cooler, and is a refinement of their earlier 120mm fan systems.
So if you are an over-clocker with a flaming hot design, we think you'll be a "fan" of this new addition. We look forward to hearing reader responses to help in answering this question.
Simply heat-up the small granular balls in either hot water or the microwave or even with a hot air gun at 150°F and easily hand-form the combined mass into your desired shape. A standard kitchen thermometer can be used to check the temperature, but be careful not to overheat.
How will you know when the material is done? As soon as it turns clear.
Although ShapeLock is extremely popular with makers and inventors, its uniqueness lies in the fact it is also useful in robotics to make skins and mount servos, sensors, and actuators.
