Tramadol US Pharmacy

2011-08-25T02:45:00.004-10:00

Yesterday my friend called me, he said that he was sick of severe pain. Usually he bought drugs at the drug store that sold freely.

But he told me that despite taking the drug from the drug store, the pain does not heal well. Therefore he asked me for help to find a suitable drug for the disease.

Luckily after I find with the help of internet, I found a suitable drug for treating the pain he suffered. The drug is Tramadol. Tramadol is a synthetic pain medication most often prescribed to treat moderately severe pain

How Tramadol Works? Tramadol works by binding to opioid receptors in the brain, thus changing the way the body senses pain. It is generally considered to be far more addictive than other popular pain medications, so an excellent choice for managing chronic pain.

Unlike the drugs purchased by my friends freely at the drug store, Tramadol should use a doctor's prescription. Because if you consume too much can lead to tramadol overdose . My friend knew that taking the drug should be in accordance with a prescription, because there are side effect of using Tramadol. Some side effects include reduced heart rate, drowsiness, difficulty breathing, fatigue, nausea, or even a heart attack.

After thinking about the various advantages and disadvantages about Tramadol, then my friends finally decided to buy tramadol to treat his illness.

TIPS FOR REDUCING VIBRATION ON SPEAKER ASSY

2011-03-26T01:22:00.007-10:00

When you make a speaker assy, there is the possibility of speakers that you create a voice disorder called sound vibration (vibration). Therefore, I will give some simple tips for those of you who are planning to make the speaker assy.

Usually the sound vibration (vibration) is caused by the air flow on narrow-gap on the speaker units with wooden cabinet. Therefore, to avoid any air flow in narrow gap between the speaker units with wood cabinets is to install a cushion on the bottom of the frame eva speaker unit.

Figure : Installe eva cushion at the bottom of the frame speaker to reduce vibration

With the cushion eva, then when the unit are screwed speakers in wood cabinets, it is expected that there is no air flow to exit through a narrow gap between the speaker units with wood cabinets.

Another thing that can cause noise on the speaker assy is caused by a "knock" the speaker cable into the wall of the speaker box (speaker cabinet). The stronger the sound produced, the greater the sound of "disorder" generated.

Therefore, to avoid it can do the following :

a. Make sure the length of wire inside the speaker cabinet as optimal as possible. If a speaker cabinet wiring is too long, then there is the possibility of the cable was going to swing and cause the voice disorder.

b. Cover the cable leading to the speaker unit with chasmere. Giving chasmere on the speaker cable will reduce the "knock" because the condition of the soft chasmere.

Figure : Example of speaker cable without chasmere

Figure : Cables speakers with chasmere

Tips so we can provide. Hope you can make a speaker assy (bok speakers) with the result sounds good and avoid the sound vibration / noise.

MAKE FIRE DETECTOR MOBILE ROBOT

2011-03-20T04:40:00.010-10:00

Preliminary

Now we will try to make a fire-detection robot. This robot is not looking for flames, but only detects whether there is fire or not. He could not determine the location of the fire ( for example: candles), but the robot can determine whether the candle is lit or extinguished.

Mobile Robot made standard by using the Servo Contionous 2 pieces. Use of this continuous servo motor ( brand Parallax) greatly facilitates the manufacture and only require 1 port to a servo motor.

Figure : Base Mobile Robot

Fire Sensor

That challenge is how do we know a candle in a state on or off? Therefore we will use the sensors detecting the existence of these sensors api. Unfortunately the cost of sensor relatively expensive at around $100 ( IDR 1000.000 ).

a. Tron UV Flame Sensor

These sensors will detect the existence of invisible light produced by the flame of a candle. The output of this sensor is very small that can not be directly linked to the system of microcontroller. It required a special driver for connecting between these sensors with the em microcontroller system.

Figure : UV Tron Sensor

b. UVTron Driver

This circuit is used to strengthen a small signal generated by the sensor UVTron Flame Sensor. Given this circuit, the output can be connected to any microcontroller system.

Figure : UVTron Driver

Once you have a flame sensor and the driver, then immediately put the fire sensor (UVTron Flame Sensor) by soldered to the driver. After that connect the driver with a system microcontroller (in this case PIC16F84 / A).

The example program (firmware) to detect the fire is as follows :

MAKE LIFTER FOR MOBILE ROBOT

2011-03-18T03:40:00.012-10:00

Preliminary

There have been many people who make the mobile robot with their respective capabilities. There is a mobile robot that has the ability to follow a black line (line follower robot), a mobile search robot light (light seeker mobile robot), a mobile robot fire detection etc.

Well now I will try to provide a way to make forklift equipment to be installed on the mobile robot. Goods which can diangat course is a lightweight goods because this is only for simulation only, not for the actual lifting.

Design Lifter

Lifter is powered by a "geared DC motor. " Yes the motor used should be a geared means using gear in front. If you use a normal DC motor, then the energy will not be strong. The function of the gear is to reinforce the torque of the dc motor. Geared DC motor can be purchased at several stores robotic components.Figure : Examples of lifting equipment for mobile robots.

The design of this lifter can be described simply as follows :

How it work ?

Geared DC motors on its axis is connected with the shaft that is connected with a belt. Belt must be strong enough if necessary using a serrated belt type. At the top mounted limit switches to restrict the movement of a fork.

At the bottom mounted switch limit down to limit the movement of a fork. Fork can only move for d ( bottom-top travel). Geared DC motors will later be powered by 12 Volt.

To control the movement of the lifter (Lifter) is used microcontroller PIC16F84 / A. But the adapter is required an IC motor driver. IC Type is L293D.

The relationship between the microcontroller PIC16F84 with L293D are as follow :

MAKE LIGHT SEEKER ROBOT

2011-03-10T05:50:00.006-10:00

Preliminary
It's nice if we could make a robot. But making such sophisticated robots humanoid robot would be too complicated for us. Only smart people who can make robots like that.

Therefore, we will try to create a robot with an easier kind of Mobile Robot. This time we will try to make a mobile robot that can find the light (light seeker).

the car robot will walk straight toward the light. If the mobile robot does not catch the rays. Then she would walk to spin until it met with rays.
The way it works is if the robot captures the light, then

It is a pleasure if we can make a toy "sophisticated" is. Besides, we can also motivate our children will advance technology so that he will get an overview of the progress of these technologies.

Figure Mobile Robot Seeker of Light (Light Seeker)

Search mobile work light system is simple. A light sensor in the form of LDR (Light Depedent resistor) is a tool that resistance would be low if there is light on its surface, whereas if there is no light at the surface (dark) then the resistance becomes high.

Rays are on sendor LDR will then be connected with a comparator (OP-AMP) for the output can be connected to a digital system of the microcontroller.

Minimum system using DT-Proto 18pin PIC so you can easily make it. In order to look more sophisticated 2x16 LCD will be installed on the robot body. This robot drive system using 2 pieces of continuous servo (rotates 360 degrees) with the brand parallax.

MAKING A SIMPLE PIC16F84 PROGRAMMER

2011-03-09T05:44:00.024-10:00

Figure Simple PIC16F84 Programmer

For those of you who have limited funds and want to learn microcontroller PIC16F84, you can do it by making your own PIC16F84 programmer. This is of course suitable for those of you who like electronics. For those of you who do not like eletronics or no time course fitting buy direct programmers.

Create a microcontroller programmer did seem difficult for beginners. Many have asked me why programmers do not work correctly. Most are due to the element capacitance (capacitive) so programmaer not work properly.

Therefore, I will try to provide a way to make progammer who have a high success rate. This is due to two things:

a. Using the serial interface (serial port)
Serial interface to send data from your computer to the microcontroller in a serial (bit by bit). For the duration of data used in such a UART IC can also be configured peniriman bit of his speed (in bps - bits per second), so it is not influenced by the speed of the computer. It is different when using parallel interface (parallel port).

b. Direct Connect to the serial port. It is intended that the distance between seriap computer port (DB9) with progammer = 0 cm. This will reduce kapasitive nature which may arise when using long cables.

These programmers require external power supply by 9 Volt which will be reduced to +5 Volt using IC 7805 or 78L05. Remember that the second IC pin layout is different (see data sheet). The use of external power supplies will also further enhance the success of programming when compared to using the power supply from the serial port.

Another component that is used quite easily obtained as ¼ watt resistors, capacitors 10uF 16 Volt and 18 pin IC socket. Special to IC sockets have a few options, namely:

a. 18pin IC sockets standard

b. Molex 18pin IC socket

c. IC 18pin ZIF socket

You can make use of all types of socket tailored to your financial ability alone. It's best to use a ZIF socket because it will not damage the legs of the microcontroller while installed or removed.

4K7 resistor value can be replaced with a value of about 2k2. For the IC voltage regulator you can use 7805 or 78L05. Remember that two different IC pins him (input pins, ground pins and output pins).

Figure of IC 7805 and IC 78L05

You need a PCB hole to install all the components including DB-9 is also mounted on the PCB. This programmer can be made as small as possible within your capabilities.

At the time of usage, it means the programmer has to be plugged directly into the terminal in Computer DB-9 PC and you open the program (software) that is suitable for example: Picprog.

MAKE A LINE SENSOR FOR MOBILE ROBOT

2011-03-08T05:09:00.014-10:00

One tool often used to make the mobile robot is a sensor line (line sensing device). Sendor which can be used as some kind of LED and LDR couples, or couples and Photodioda Infra Red LEDs.

For now we will try to make the sensor line by using a finished product that is: DT-Sense Photo Reflector Sensor. This sensor contains Photodioda LED Infrared and integrated on a small PCB.

The advantages of this product is that between an infrared LED and photodioda direct integrated as one part. And technically it is small, so easy to be installed on the mobile robot you made.

Figure DT-Sense Image Sensor Photo Reflector

But technically, this sensor can not be directly used to detect the line. We should add a simple circuit with OP-AMP to form the comparator.

Usefulness of this additional circuit is to adjust the sensitivity of the sensor that we make of this. If no additional set of OP-AMP, then to adjust the sensitivity we have to set the distance between the sensor and the floor. This is certainly not practical and should be avoided. Now with the addition of OP-AMP circuit (comparator), the sensor can be mounted at a certain distance and stay alone. To set the sensor sensitivity way is to adjust the Trim POT (Trimmer potentiometer) on the OP-AMP circuit.

Here's how the line-detection sensors on Mobile Robot. Infrared LEDs will emit light to the floor. If the floor is white, the light will be reflected and received by photodioda (IR Receiver). So they will know that the floor is white (not online).

Meanwhile, if infrared rays emitted by the LED Infrared terpancara on the floor of the black (line), then the rays will be absorbed, so photodioda (IR receiver) did not receive infrared beams. So they will know that the robot is on top of black line.

What you should know we can use a black line on the floor white, or white line on the floor black. This is not an issue, only different in the program only.

The series of OP-AMP to make the comparator is as follows.

Figure Comparator Circuit based on LM-358

The circuit in the circle was replaced with DT Sense Photo Reflector Sensor. As for the OP-AMP is used can use any type of common OP-AMP, but on the above project using the LM 358. By using the LM-358, we can use to make 2 sensors because of the packaging there are 2 LM-358 OP-AMP.

How to Use

After the appliance is installed, then confronted the sensor DT-Sense Photo Reflector sensor to the floor white. Arrange in advance to the height of the floor sensor in accordance with the actual future that will be mounted on mobile robots.

Set-set Trim POT until LED lights up or pin 1 pad LM 358 voltage + 5 volts. Then faced the sensor to the black floor (for example, we put black tape on the floor), set the trim POT for the LED die (or the voltage on pin 1 LM 358 voltage 0 Volt). Bottom line: when the sensor above the white color LED lights, if the sensor above the black color of the LED die. If you do not like this then set up a state-trimpot set like this.

Preliminary

To be able to take advantage of the microcontroller as a control tool, we must have a device called Programmmer Microcontroller / Downloader Microcontroller. This tool is useful is to fill in the firmware into the chip microcontroller PIC16F84 / A.

One of the tools a programmer / downloader Microcontroller PIC16F84 / A is to be discussed is the DT-HiQ Programmer ICSP PIC. This tool is linked to the parallel port (LPT) on your desktop computer. Furthermore, the downloader cable connected to Microcontroller PIC16F84 / A. The system uses the system serial programming hence the ICSP (In Circuit Serial Programmer).

The advantage is that when programming microcontrollers, Microcontroller IC does not need to be removed. So do not be revoked IC microcontroller to program. This is different from parallel programming system in which the IC microcontroller removed and inserted into the ZIF socket. Done programmable IC retrieved and installed again. Such systems are less practical.

Starting from the desire to improve the signal reception of the USB modem at home for his reception signal can be maximized. This is because the modem is installed inside the house, so that may be received signal tends to lack.

Incidentally there is former home of fruit scales that are not used then immediately an idea to fix this usb modem signal.

Working Step

1. Prepare materials that will be used of the metal container, a USB modem, USB extension cable.

Figure 1. The parts needed

2. Take the container of fruit scales that have been unused. This container is made of metal that can improve signal reception for our usb modem.

Figure 2. Containers of fruit Scales

3. Using a pencil / pen make the midpoint of the container. Create a small box about the size of a usb modem which will be drilled.

Figure 3. Give a mark with a pen

4. Once marking is complete, then immediately punctured by using a minus screw driver (test pen) and a hammer.

Figure 4. Perforation in the container using hammer

5. After finishing hole, then plug the usb cable extension which we have prepared.

Figure 5. Connect the USB cable extension.

. 6. Tie cable tie on the remaining parts of metal and a usb extension so that is mechanically strong

Figure 6. Tie with a cable tie

7. Take hotmelt gun (hot glue gun) and give hotmelt on the inside and the outside until it is strong enough.

Figure 7. Give with hotmelt glue gun

8. Wait until the glue dried. After the glue dried attach a USB modem (do not forget to install the SIM card it).

Figure 8. Installing the USB Modem

9. Place on a table near our computers and try to see the signal obtained. Find a position that causes the signal can be maximized.

Figure 9. Attach usb antenna on the table / computer

10. Check the signal on Mobile Modem software e usb modem built it.

Figure 10. Signal strength 99%

CONTROLLING 4X16 LCD WITH PIC16F84/A

2011-03-04T05:27:00.007-10:00

Connecting PIC16F84/A with 4x16 LCD

Normally we often use a 2x16 LCD for projects that we make. But there are times when we need a LCD which looks lenih wide. Therefore, one solution is to use a larger LCD which is 4 nautical characters x16.

How do I connect a PIC16F84 microcontroller with LCD 4 x 16? Do not worry I'll show you how the program comes with sample listing for your easy learning.

Connecting the LCD to PIC16F84

LCD 4 x 16 is connected with microcontroller PIC16F84 using standard connection such as in projects that use the LCD 2 x 16. So the pins on the LCD controller is compatible with LCD 4x16 2x16.

Example Programs Listings

Here we provide sample listings to adjust LCD 4x16 with PIC16F84 microcontroller. You can develop it to suit your needs.

MAKE REMOTE CONTROLLED LINE FOLLOWER ROBOT

2007-10-30T20:35:00.020-10:00

Pendahuluan

What we call “Remote Controlled Line Follower Mobile Robot” is a mobile robot that follow the line ( black line on white floor ) which have on / off facility that controlled by remote control. To reduce complexity of program code , then remote controle not using decoding system.SO all type of remote can be used an any button can be used to activate or stopped the line follower robot.

So to make line follower mobile robot running, we must press a button ( whatever button ) on the remote. So Line Follower Mobile Robot will run follow black line on the floor . If we press any button on the remote, then Robot will stop.

Robot Control

To control the robot, it will use microcontroller PIC16F84 with due consideration

The second sensor is a sensor Photos Fotek brand (or similar: OMRON, Panasonic, etc.). These sensors are often used on conveyors in factories or on machines such as engines etc. Auto Insertion. The sensor is worth a bit expensive for hobbies, yet easy to use.
This sensor is used to detect black or white. The principle works is simple. The white color will reflect light that is sent from these sensors, while the black color will absorb light. On this basis, the output of this sensor can be created (with additional interface) logic high and low in accordance with the existing color dibawahnya.i.

Robot Mover

To move the Line Follower can be worn 2 choices of a DC motor or servo motor. If you will use a DC motor then must use a DC motor which is mounted gear system (geared DC motors). Well this bike is still hard to find, so the choice fell to a servo motor. Besides, the servo motor can be controlled directly from the microcontroller PIC16F84 with no additional IC-driver again.

Preliminary

The term "Line Follower Remote Controlled Mobile Robot" is a robot car that will follow the line (black line on white ground), where he has a facility start / stop is controlled using the remote control. To reduce the complexity of the program, then here are not using the remote control decoding functions. So any and all types of remote any button can be used to activate the (road) or disable (stop) line follower robots.

So to make a line follower robot walking, then we have to press a button (any) on the remote. So Line Follower Robot will run following the black line on white base. If we press the back button (whatever) on the remote, then the robot will stop and so on.

Robot Control

To control the robot, it will be used microcontroller PIC16F84 with due consideration to the relatively small size making it suitable for line follower robot controller of this. Microcontroller itself will receive data from remote sensors and photo sensors. Photo sensor (brand Fotek) is a sensor to distinguish a black line on white base.

As for output, the microcontroller will be connected with 2 of the servo motor (or similar brand Parallax continuous type) and 2 pieces LEDs. The diagram of the robot that will be created is as follows.

Preliminary
In the world of electronics and robotics, the use of LCD (Liquid Crystal Display) is already common. Although there are many who think that using the LCD is already. Indeed, for those who have never used the LCD, will feel yourself how hard to program a microcontroller to control the LCD.
But now more and more literature on how to connect a microcontroller with LCD, so the use of LCDs is now increasingly common for the students nor hobbys electronics. LCD availability of a general nature (compatible with one another) is very beneficial. It makes programmers, of the LCD does not depend on the brand LCD itself.

LCD Overview
Before explaining about what the LCD Back Pack, discusses a little about the basics of programming the LCD. This may be necessary for our brothers who just know / learn the microcontroller.
LCD is a tool for displaying numbers or text so that the tool use this LCD will look professional. Use of this LCD is different from the use of Seven Segment (Figure 7 segments). If the 7 segment display is a passive device, the LCD can be considered as an active tool. This is because the LCD has installed a Hitachi HD44780 processor.
Because the processor tersebutlah, then to use the LCD to use a microcontroller or system can use the parallel port on the computer. This is not because we must provide the initialization process prior to using the LCD.
The block diagram of the LCD is as shown below.

Figure Diagram Block LCD

Parallel vs Serial LCD LCD
In general, LCDs are more outstanding in Indonesia is a parallel LCD, but actually there is one type of LCD is not so widely used in Indonesia, the Serial LCD. If using a parallel LCD we have to use more than 8 channels of I / O, so if using a serial LCD the total number of I / O that is used far less, because the process of sending data using serial techniques. Serial LCD many made by Scott Edwards Electronics America.LCD BackPack

Generally, the LCD will take up a lot line I / O on a microcontroller system. If the microcontroller has a number of I / O a lot, certainly not a problem. Problems will arise if we use a pen system microcontroller I / O are limited. If you must use a small microcontroller (with I / O limited) and must use the LCD what should we do to save I / O?
A solution was to use the LCD BackPack. LCD BackPack is an additional PCB that is placed on the "back" LCD where they are located on the PCB BackPack Sebuat PIC16F84 microcontroller (equation) used to control the LCD.

With the PCB BackPack, the entire LCD control was taken over by the microcontroller PIC16F84 exist in BackPack. The communication between our minimum system with LCD BackPack using 1 line only. Total lines needed to connect to LCD + BackPack is 2 lanes. That is a path I / O and Ground. This certainly represents a significant saving path.

Figure Connection LCD,PCB-LCD BackPack and Minimum System PIC16F84

By using this BackPack + LCD microcontroller, the system we only need one lane of I / O just to get in touch with the LCD. Of course, this causes the path I / O is still widely available for other purposes.
