Voltage Divider
A handy engineering utility that solves for voltages or resistor values in a common voltage divider circuit. Enter three terms (out of Vin, Vout, R1 or R2) and this app will solve for the fourth term automatically. The resistor picker will only let you pick from actual resistor values that exist. It’s a great time saving tool for quickly selecting resistor values in a switching power supply design or any other circuit that incorporates a voltage divider.
When solving for a voltage, select two resistor values and one of the voltages. The remaining voltage will be displayed automatically. The max and min possible voltages will also be displayed based on the resistor tolerances. The current and power through the divider will be displayed at the bottom of the screen.
When solving for a resistor value, select two voltages and one resistor value. The remaining resistor value will be displayed in yellow. This is an ideal value. Use the resistor picker to select an actual resistor value close to that ideal value. You can then tell the app to solve for Vin or Vout to see if the resulting voltage meets your design requirements.
Smartwrite – English Lessons
Having problems with punctuation? Phrases? Use Smartwrite to correct them! What to improve your English? Look into the English lessons!
So what exactly can it do?
1. It corrects common phrases we all get wrong (“should of” becomes “should have”, “I’m good” becomes “I’m well”, etc.)
2. It works with punctuation and allows it to add spaces when needed (at the end of a sentence, after a comma, after a colon, etc.).
3. It capitalizes the beginning of a sentence.
4. Replace slang words with the correct English word (this is useful if you are in a hurry to write something important).
5. It can still do all of this without requiring any internet connection!
SciCalc82
Simple Scientific Calculator adhering to the style of the early 1980s. Easy to use and familiar for those of us from that era.
Adds a touch of realism in look and feel, layout, key click sounds, LCD display digits and response. Functions and operations are as you’re used to, but adds a few more features that you’d wished you’d had back then, to give you a modern day usable device.
