Feedback
I love my new saw purchased through Amazon.com, it is light weight, quiet, easy to adjust and works like a charm. Being 69 and a woman, the light weight bit is extremely important, I worked with it all day today cutting 2×6 boards for my garden’s 20 raised bed frames and wasn’t the least fatigued. (Well, at least not from repeatedly lifting the saw…)

Most household electrical outlet mounted at eye level or lower not very far from the reach of children. Children can play in punching power. If protective equipment is carefree can be used to plug the holes. Prevent electric shock our loved ones in the family people from electric shock may be disabled for life some people may even die. We do not overlook safety. All be prevented if every precaution.

A versatile and cheap digital counter circuits by CD4510 & CD4543

elecfree — Tue, 19 Feb 2013 14:32:47 +0000

This is versatile digital counter circuit, that as a cheap due to basic components you can buy in many electronic shop. My friend said the some circuits that price same this circuit may be not worth it. You can apply too much model as you want with special feature of this circuit following.
1.A count up or count down the time.
2. Can connect output to a 7 segment LED both a Cathode common or Anode common.
3. Can store a collection of information
4. Can set number counting in advance.

In circuit as figure 1 is shown normal operation, by set the circuit are 2 main, that if we want more than this, it can be connected together to added unlimited.

Figure 1 is A versatile and cheap digital counter circuit

The heart of the circuit is composed of 2 parts.
1. A decoder and drive LED display.
2. The counter number on the Binary Code Decimal Output that use IC2-CD4510

5V 3A switching power supply by LM2576

elecfree — Mon, 18 Feb 2013 23:46:25 +0000

LM2576-5.0 is simple switching power supply 3A step down regulator for power digital circuits.

Sometimes we need to work on the car or travel outside the area. The without wires internet ADSL. When use the Internet was Using 3G aircards and distributed to the Internet via wireless. It uses the power supply of 5V 2A. Because it is digital circuit which uses a 10 watt high power ever.

When it comes to used in cars. We can uses power from the cigarette lighter of a car.But have the voltage 12 volts, so it must reduced the voltage down to 5 voltsat current is 2 amperes. We have a lot of choices. When before I use the transistor and IC-7805 for this job. However, when considered with caution. To its low performance. have high temperature and large, as the identity of the generally linear ICs. This work, we try to do the switching IC.

IC-LM2576-5.0. (DC to DC step down voltage regulator) It is a very interesting number. It maintains a constant the voltage of approximately 5 volts and current 3A. Compatible with the device easily. On the manufacturer’s manual. I smile with ease. It is very easy to use. as Figure 1. Will see that, there are only four more devices only are C1-100uF , D1-1N5822,L1-100uH, C2-1000uF. The input voltage levels is 7volts to 40volts. My favorite feature is the runs with high frequency. IC is not hot. It can hold a small cooler. And Used continuously for a long time.
