In mathematics and the arts, two quantities are in the golden ratio if the ratio of the sum of the quantities to the larger quantity is equal to the ratio of the larger quantity to the smaller one. The golden ratio is an irrational mathematical constant, approximately 1.61803398874989. Other names frequently used for the golden ratio are the golden section and golden mean. Other terms encountered include extreme and mean ratio, medial section, divine proportion, divine section (Latin: sectio divina), golden proportion, golden cut, golden number, and mean of Phidias
If the boiler is running efficiently there may be no need to service it. Simply test the boiler with your analyser and obtain the oxygen, carbon monoxide and carbon dioxide values.
Input the values from the analyser into the Gas Ratio Calculator, the CO/CO2 ratio will be calculated and advice also given on whether the boiler should be serviced or not.

1. Calculate resistor values of voltage divider
2. Calculate resistor values of inverting amplifier gain
3. Save component values in CSV file (Excel file)
4. Use preferred values of resistors
Features in PRO version only:
1. No Ad
2. Can use preferred value 1% for resistor
3. No limitation

You can calculate TT01 gear ratio and motor mount with this app!
- Gear Ratio
- Motor Mount
This app is ONLY for use with Tamiya TT-01!!

Easy to use:
★ Place the phone alongside the track, with the red line on the camera preview facing on a track lane.
★ Press calibrate: the app will calibrate in a couple seconds.
★ Press start and put your Mini4WD in the track.
★ The app will record your lap times as the Mini4WD passes under the red line.
You can export the lap list as CSV (for import in Excel) or send it directly via email.
Can also be used with slot cars or for other purposes.
Please use the app in a well lit environment. The app uses differences in shadow to detect the passing car. Other moving things that cast shadows on the track will interfere with time recording. Good lighting also improves camera framerate so times will be more precise.

For more precise timing, please purchase the original Tamiya (#15184) Lap Timer.
1) Place the phone with the camera facing on a track lane. Keep it still.
3) Press start, the timer will start when the car passes.
(You don't need to calibrate.)
Q. Can be calibrated when it is started, if the terminal is moved, how to calibrate again?
A. You can be done from the calibration of the menu.
Q.It seems there is a difference in the accuracy of the time by the phone...
A.Yes. There are differences in the accuracy of the time by the phone. It seems to vary depending on the preview frame rate of the camera phone.
Q. Is it possible to silence sound?
A. Yes, I can be changed in the options. If you do not mute the sound will increase the accuracy of time.
Q. It will get the lap timer or start with the vibration of the car and shadow.
A. Please try to increase the value of sensitivity. Number to the left, which is displayed in the camera at the value, is the right sensitivity(threshold).Please set number of value is greater than the sensitivity only when the car was Tsu horizontal skills. In addition, I can also specify the maximum value of the millisecond intervals to get the lap. Car does not count the lap beside me skills within milliseconds that you specify, you can prevent inadvertent count.
Requests are welcome.

• The main function
And measurement of the rotational speed
• How to use
· Tap the "Start"
· Turn the motor
· Approach the motor to the microphone
· Rotational speed is measured
· Noise is large, it may not be recognized well
Will be easier to (5 or 10 times the average) recognition When you change the "Boundary value setting", but becomes easier if mistaken.
Lap time measurement of mini4WD and Mini-Z etc.
- lap time measurement (1/100 second accuracy)
- lap count setting (5,10,20,50, ∞)
- saving lap time
- save data viewing
- The transmission of the laptime to other apps mail, etc.
- By using the gyro sensor, you can measure the lap time of 1/100 second precision.
(In the actual measurement in XperiaZL2, there was a 4/1000 seconds of measurement accuracy)
- The measured lap times, you can transfer to the e-mail and Facebook, etc. of other apps.
You can create easily with cardboard and tape, but it is necessary to devise for transmitting vibrations to the smartphone.
This app is for 1/10 R/C car.
- Final gear ratio
- Motor RPM
- Potential Speed
Enter the transmission ratio, spur, and pinion to generate Final gear ratio.
Enter tire diameter, motor KV and battery voltage to get potential speed and max motor RPM.
