Hand writing effect in power point

Article written using PowerPoint 2013

Have some text already typed into a text box With segoe print font.

Get a picture of a hand holding a pen and scale it appropriately under the text.

Go to animation then animation pane.

select all the text and click the fade animation.

Set the duration to 0.5.

In the animation pane window, go to the handwriting animation event.

Click the down arrow next to the animation event and click effect options. Set Animate text to by letter.

Directly under Animate text, Set to 100% delay between letters then click ok to close the box. Test the animation, the letters should appear one by one.

Now to animating the hand holding a pen.

Multiply the number of letters in the text by the duration of the last animation which is 0.5.

This value will be the duration of the hand animation.

Go to the animation window, then look for and click motion paths, then custom paths.

The cursor will change to a crosshair, zoom into the text, then with your mouse or pen, trace the path of the text from start to finish as if you were writing it. 

The path will be recorded. Double click to preview the animation. Change the duration to the value previously calculated for the hand animation.

In the animation pane window click the down arrow next to the hand animation.

Then click effect options and set smooth start and smooth end to 0 sec. then click ok

Test the animation to see changes.

Now the text and hand animation has been made.

Try to position the hand holding pen picture under the text as realistically as possible.

Set the hand holding pen picture to bring to front.

Set the hand holding pen animation to start: with previous above the animation pane.

Test the animation. The hand holding pen should be writing the text smoothly now.

To make the hand holding pen go away after the animation you need an exit animation.

Go to add animation and click fly out

Set the fly out animation to Start: after previous

How to connect batteries in series and parallel. Simply explained .

Battery cells connected in series

Batteries connected in series

A series connection of batteries is achieved when the negative terminal of one battery  cell is connected to the positive terminal of another battery cell. 2 or more battery cells can be connected this way. An example of application of series connection of batteries is in the use of a touch light. Typically 2 batteries are connected in series for the touch light to come on.

In a series connection of batteries, voltage increases while current stays constant.

For example let’s say 2 battery cells are rated 1.5 V and 1A each and the cells are connected in series. Then the combined voltage for the series connection  becomes 1.5V + 1.5V = 3V but the current remains 1A.

Using the previous cell ratings, an electrical appliance that needs 6 volts to come on will require 4 battery cell connection in series

Battery cells connected in parallel.

batteries connected in parallel

A parallel connection of batteries is achieved when the positive terminal of one battery cell is connected to the positive terminal of another battery cell. The same is done to the negative terminals of the battery cells.

In a parallel battery connection, voltage stays constant but current increases.

For example let’s say 2 battery cells are rated 1.5V and 1A each. If the batteries are connected in parallel then their combined ratings are 1.5V and (1A +1A) = 2A

Application of series and parallel connection of battery cells

A very good knowledge of series and parallel connection of battery cells enables the development of battery packs with with different voltage ratings and capacities.

Forms of Lithium Batteries

Lithium batteries have been available since the 1970s. Technological advances in Lithium battery research have made it the most sought after now. Lithium batteries have a high energy to weight ratio, over 1000 discharge cycles and fast recharging. These batteries are used in mobile phones, security gadgets, drones, electric cars and so on.

Composition of a typical lithium battery cell.

composition of a lithium battery cell

A lithium battery is composed of 4 parts namely;

Cathode: (+ terminal). It is a lithium compound mixed with other materials.

Anode: (+negative terminal). It is a graphite material.

Electrolyte:  An organic compound containing lithium salts to transfer lithium ions.

Porous separator:  Allows lithium ions to pass through itself but separating the cathode and anode.

Form of Lithium batteries

Pouch lithium cell

Pouch: These forms  of lithium batteries look like thin foil bags. They have two terminals at an edge of the porch. They are lightweight and cheap to produce. They are used to power cell phones and some types of  laptops.

Prismatic lithium ion cell

Prismatic: these are similar to pouch in form but more robust. The battery cells are placed in rigid rectangular cases. They have threaded terminals which makes building of larger batteries easier. They are used in high energy storage devices such as electric vehicles and home use.

Cylindrical lithium ion cell

Cylindrical: These forms of lithium batteries look like the AA batteries we use in our touch lights and remote controls. However the cylindrical lithium battery form is much larger than a typical AA battery in size. Unlike pouch and prismatic forms of lithium batteries, the sizes of cylindrical lithium batteries are standardized. The most commonly used cylindrical battery size is the 18650 cell. The 18650 cell means that the Lithium battery cell is 18mm in diameter and 65 mm long. There are other standard sizes too like the 14500 cell ( 14mm dia & 50mm length) and the 26650 cell( 26mm dia & 65 mm length). Cylindrical lithium battery cells are used in laptops, power banks, electric cars, solar system and so on.

Liverpool and Real Madrid into Final of Champions League Final

Liverpool vs Real Madrid. Final UEFA Champions League

It’s Liverpool Vs Real Madrid in the Champions League Final 2021/ 2022 edition.

It was not easy for both teams in the semis.

Liverpool, who thought they had one foot in the final after their first leg win over Villarreal by 2-0 at Anfield got a run for their money after Villarreal levelled up in the first half of the second leg. But just as it happened in the first leg when the scores were still 0-0 at the end of the first half, Villarreal again capitulated in the second half and allowed Liverpool to score 3 goals giving Liverpool a 5-2 win on aggregate. Jurgen Klopp was a relieved man after the game, he knew at a point in the game ,they were almost knocked out.

Real Madrid are getting better and better. Just like their comeback win against Chelsea in the quarters, they also came back to beat inform Manchester City 6-5 on aggregate. Karim Benzema is the joker for Real Madrid. In the quarter final, he  scored a hat trick against Chelsea and nailed Chelsea’s coffin with the deciding goal via a penalty in extra time. The same happened with Man City. Manchester City were winning 5-3 on aggregate by the 73rd minute, However Real Madrid Levelled up and once again Karim Benzema nailed City’s coffin with a penalty goal in extra time to win 6-5 on aggregate.

Real Madrid, the 13 time winners, are the favorites to lift the trophy. Liverpool will have to be at their very best and take care of Benzema to stand a chance.

sugar added to popcorn

Popcorn is ready to be served.

Further Notes on making popcorn

Make sure you cover the pot while corn is looking otherwise the popcorn will fall to the ground.

Use low to medium heat to cook your popcorn otherwise it might get burnt.

After  all the corn has popped, switch off the cooker before adding sugar and mixing with the popcorn. Otherwise the sugar will melt and then burn giving your popcorn a burnt taste.

Don’t put too many corn grains in the pot. The amount of grains you put should barely cover the base of the cooking pot
