ProCodeCG Kids Regular Coding Class – Open Topics – 23 Sep 2017

Wow, lots of new things and amazing progress today! 🙂 We have several topics and research running 🙂

Ain has made huge progress on GameMaker like always

This is his latest game 🙂

Using a very complex technique

and numerous sprites and objects to make it looks so real 🙂

Ain designed every sprite very carefully and in detail

For the next lesson, Ain started learning creating apps 🙂

Ain’s first app on Android  🙂

Ain will be good at this one too 🙂

Emma had finished her task to create a Tic-Tac-Toe algorithm in C to choose the best move

It works

The code:

The new task given to Emma 😉

Emma is digesting the task and we’re sure she’ll find out how to solve it 😉

Yaay, we had a newcomer: Adin

Adin finished the first time very quickly

and got the certicate 🙂

Moved on to CodeCombat and finished it

And then started LightBots 🙂

Capt. Faris is now start working on Instagram crawling 🙂

He’s not only making it work on his laptop

But make it work on a Mac too 😉

Neila wanted to learn some Sketch Up today 🙂

Jundy was there to help, yaaay 🙂 Jundy is very fluent with Sketch Up so he’s the right person to teach Neila 😉

Jundy helped Neila to install

And taught her basic things to start with

Then Neila started to learn GameMaker. Ain taught her some tricks 🙂

Neila made her first game 🙂

and then back to Minecraft 😀

J also helped Azriel to set up Minecraft Server 🙂

Azriel (Ajil) wasn’t captured in the pic but this is him starting to code with JavaScript on Minecraft 😉

Cinta continued her creating apps project 🙂

With more and more complex blocks 🙂

Vian was in the mood of doing some GameMaker today 🙂

And then discussed things with Ain and Jundy

Clarence had a coding project to finish. The task is to read a file and sort the content based on certain field

With Capt. Faris close assistance

  

The class

Papa Jundy babysitting Jundy’s little sister 🙂

Mama Ain helped Ain to create a Thunkable account 🙂

And these two guys were still working when all of us leave the building 😀

See you next week guys! We really appreciate your dedication! 🙂

ProCodeCG Kids Regular Coding Class – Arduino/ESPectro Programming – 23 Sep 2017

Today we picked up where we left last week: making a micro servo works 🙂

There were on only two kids working on Arduino/ESPectro Programming 🙂 This is Ozan

He had successfully made micro servo works, and ready to add an ultrasonic sensor to activate the micro servo 🙂

Nafis was working on the same thing

He added an ultrasonic to activate the micro servo and worked 😉

Next week we will explore more things, and help the other kids to catch up 🙂

 

ProCodeCG codeMeetUp() #111 – Philosophy of BlockChain

ProCodeCG codeMeetUp() #111 🙂

Philosophy of Blockchain by Prof. Budi Rahardjo 🙂

Blockchain is not equal with Bitcoin

Example of transaction

how miner work

initiating amount of bitcoin for A and A send some to B

A chain will be created for each transaction

The transaction will be hashed with certain criteria

Example of simple hash

A demo of transaction recording and creating chain in PERL

creating hash that meets criteria for each transaction

the code: generating chain, calculate hash, etc. Showing how mining is done

How miner work

Summary

The audience

We had long discussions 🙂

Thanks for coming 🙂

See you on the next ProCodeCG codeMeetUp() 🙂

ProCodeCG Kids Regular Coding Class – Open Topics – 16 Sep 2017

 

ProCodeCG Open Topics Class today 🙂

Emma is still working on AI for TicTacToe

She is developing strategy to choose the best move

There are still some bugs and she is going to fix the data structure and algorithm 🙂

Clarence started to learn java and data structure 🙂

He created a java program for monitoring graphics performance

And his project is to parse a file and sort the content

. 

Based on certain number and name

The file, with comma as delimiters

The parsing is done, now before sorting we need to convert the data from integer to string or vice versa

Capt. Faris who is very proficient in Java comes to help

and next is to sort 🙂

Capt. Faris always has ways to solve things 🙂

While Cinta is back to creating apps 🙂

She is creating a To Do List Application

Altair starts to learn Python with CodeCombat 🙂

Al seems to like learning to code this way 🙂

CodeCombat teaches kids logics and basic programming with a tool looking like a game 🙂

There are missions to accomplish and kids have to write codes on the right window 🙂

Altair helps Adit to solve the problems to finish the missions

Adit is very good himself but sometimes he needs a little clue to keep on going

A fun way to learn coding (Python) 😉

Conquering challenge after challenge

Tyo is still working on his temperature measurement application

It is working nicely now, converting both ways from Celcius to Fahrenheit

We probably will improve the GUI to be make it possible to convert to and from more temperature units

Capt. Faris helps Tyo to improve the code

Faris added textfield listener so the code will automatically show the result on the other textbox when the user enter a number on one textbox

 

Sabrina is back to learn web programming 🙂

She has finished one stage

and with the help of Capt. Faris has fixed some errors

In a few weeks Sabrina will be ready to create his own web design with HTML, CSS and Javascript 😉

Azriel learns different topic today

He learns JavaScript with Crunchzilla Monster.

Azriel learns about variables, looping and conditions. Next week Azriel will be learning JavaScript for Minecraft Modding 🙂

While Capt. Faris is working on this research 😀

We’re going to develop many things using the result of Faris’ research 🙂 We’ll be reporting soon 😉

 

 

ProCodeCG Kids Regular Coding Class – Arduino/ESPectro Programming – 16 Sep 2017

The class is ready 🙂

Today we are ready to explore new component: micro servo 🙂 Nafis is ready 🙂 *notice the screwdriver and the breadboard on his forehead LOL

Nafis is so excited to see how a micro servo work 🙂

Nafis hasn’t finished typing the code so we’re going to try it next week 😉

While Rezky still needs some time to test his new LCD I2C (we replaced the previous one with a new one)

the new one didn’t work so we give him the working one and going to claim this one with another replacement. So Rezky will start exploration next week 🙂

Reza is back 🙂

He has to catch up with several previous projects before he can start his new project 🙂

Project for Reza today is Ultrasonic Counter 🙂

He struggles with libraries and the schematic. Still have to work on it next week 🙂

Cinta learns robotic at school, and apparently what she has learn in ProCodeCG classes turn out to be very useful 🙂

The code Cinta developed to turn on a set of LEDs to light up in a certain pattern according to what we enter from serial monitor

Cinta still has the schematic on the breadboard

These for LED’s will blink in a pattern defined from serial monitor

Awesome work, Cinta 🙂

Next week we will do more projects and fix bugs and errors 🙂

Glad to know that our class helps kids with their school 🙂

We’ll be reporting again next 🙂

ProCodeCG Sensor Data Acquisition Training – 11 Sept 2017

Today we trained lecturers for Politeknik Negeri Pontianak on how to do data acquisition from current sensors 🙂

Class preparation

We split the team into two: hardware and software. The hardware team started to assemble the components

while the software team installing the application and libraries

ESPectro basic testing: blink

and neopixel animation

Then we’re ready to connect ESPectro to the circuit and sensor

We compared the circuit with the one that has been tested and verified

Still didn’t work

It took lots of retrying, switching components and we tried every solution possible and think of every source of errors

still didn’t work

We just kept trying

and after we changed the resistors with metal film ones, it worked! 😀

Current reading when the switch is on

when off

when on and off again

The effort was worth it 🙂 We finally finished the training and ready to collect data for further research and analysis 🙂

ProCodeCG Kids Regular Coding Class – Open Topics – 9 Sept 2017

Hello!

This Saturday we had two newcomers 🙂 This one is Al 🙂

Al learned intro to programming with Minecraft Hour of Code 🙂

After he finished task one, Al continued to learn about procedures with LightBot 😉

Then he continued with Blockly Games 🙂 Lots of work today Al, well done 🙂

The second newcomer is Adit 🙂

Adit learned the same things Al did 🙂

Adit was tutored by Capt. Faris 🙂

Finished the first task

and then move on to the next 🙂 Adit seemed so excited 🙂

Emma was still working TicTacToe strategy

The code generated some errors after Emma added a new function

Well, with a code looking like this, we certainly need time to find out the problem 🙂

Aidia started to create games 🙂 With the guide of Capt. Faris 🙂

Aidia already had ideas in mind about the game she was going to create 🙂

Aidia was so excited to create her own sprites 🙂

Finally, Aidia’s first game 🙂

She just couldn’t stop 😉

Ain! He came with lots and LOTS of progress 🙂

From all the tasks and challenges, he created this “Kresek Terbang” game 🙂

The game is so neatly created and detail, using brilliant tricks and techniques

Like usual, Ain never do anything less than excellent 🙂 Look at how many sprites and object he created 😀

Ain also uses a very smart way to put objects in random while the screen moving to the left

Ain gave lots of tricks and idea to Vian 🙂

Vian was going to make what’s in his head happen 🙂

Vian learned lots of new tricks to make his ideas happen 🙂 Well done Vian 🙂

Vian also wanted to create his own logo 😀

So we let him express his creativity for a whiel 😀

Ajil’s game now working just fine 🙂 Last week we had the GameMaker kept hiccuping 😀

Ajil tested all the game he had created

Making sure all is running smoothly 🙂 Next week Ajil will be ready to learn something new 🙂

Tyo had a new idea for a new project 🙂

He wanted to create a temperature converter 🙂

Tyo is a very determined boy. He insisted to write his own code, line per line. He refused to copy paste examples from the internet 🙂  Tyo has a problem with casting this variable to integer

Capt. Faris helped him out 🙂

So this is going to be Tyo’s homework and we’ll see the progress next week 🙂

Look at what Capt. Faris learned in the class while teaching 🙂

Capt. Faris showed Capt. BR his ProCodeCG Attendance App with Face Recognition 😉

Faris took my pics last week and let the code learn, and now it recognize my face 🙂

Not yet recognize Capt. BR

Because the system has only learned Faris’ and my face, Capt. BR was identified as Faris 😀 Later Faris took pics of Capt. BR, feed it to the system, and it can recognize Capt. BR too 🙂 Awesome!

Well, when Faris’ laptop goes like this, that means the class is over 🙂

See you next week! 🙂

 

ProCodeCG Kids Regular Coding Class – Arduino/ESPectro Programming – 9 Sept 2017

Our Arduino/ESPectro Programming Class this morning 🙂

Ozan was ready to modify automatic pedestrian traffic light with ultrasonic 🙂 We were going to add LCD to display information to pedestrian 🙂

It worked 🙂

The display will show the color of the traffic light:

red

yellow

green. Ozan had to change all the text into some info for pedestrian so they will know when to cross and how many times left 🙂

Nafis

and Rezky were working on the same project as Ozan

These two like to work together

helping each other finding bugs and make the schematics 🙂

and worked 🙂

We just had Uben back! His usual laptop was in repair so he brought another one. We spent some time to install and setup everything 🙂

Uben was told to create ultrasonic counter

 

Uben likes to assemble things like this 🙂

Too bad we didn’t had time to type in the code and compile it. Going to do it next week! 🙂

Next week we will explore projects with micro servo! 😉

ProCodeCG Kids Regular Coding Kids – Open Topics – 2 Sep 2017

ProCodeCG Open Topics Kids Coding Class 🙂

These girls, Echa and Aidia arrived early 🙂

They’re ready to learn more about programming with Minecraft 🙂

Echa and Aidia started to learn Minecraft Designer before they start coding with JavaScript on Spigot Server 🙂

Neila joined the group of Minecraft Modding with Echa and Aidia 🙂

They logged in to the same Spigot Server so they can play and code together 🙂

Capt. Faris (grey jacket) helped the girls with starting up the server and logging in to it 🙂

Ain! So excited to see the progress 🙂

Ain has created an amazing game with nine levels 🙂

The game is very well and carefully designed 🙂

Each levels offers different challenges *that escalates in an unpredictable way 😀

Ain has also created another game, a very detailed game with animations

He creates LOTS of sprites

and each sprite has LOTS of images for animations

This one is totally a detailed and determined kid 🙂

The game is about a watering can that can walk (while animating)

and when it approaches the plant and water it, the plant will grow 🙂

the code of how the plant changing sprite to give growing animation 🙂

And after demoing those two awesome games, Ain created another one

He hasn’t explained how this game work

because after Vian arrived, Ain was told to give ideas to Vian 😉

so they teamed up to create games together 🙂

Emma was still working on the Tic-Tac-Toe project

She was in the process of creating data structure and algorithm to make computer chooses the best possible move

She developed some functions and started to list move possibilities

the SPOTS variable shows the possible positions to move. The algorithm still choose the move closer to the upper left cell. Will be improved after the weighting process has been figured out.

Capt. Faris on duty 🙂

Very busy doing his research on ProCodeCG Attendance List with Face Recognition 🙂

Faris was doing some training to his code

So it will recognize his face and tell the system that he has logged in 🙂

The result of the matching process

And then he started to train the code with different datasets so it will recognize different person 😉

There are always so much things going on, and there will be more next week! 😉

 

ProCodeCG Kids Regular Coding Class – Arduno/ESPectro Programming – 2 Sep 2017

Hello Saturday Coding Class 🙂

Today more kids coming to continue their projects 🙂

Koosha brings his elevator project to the class 🙂

It has seven segment to display the floor number plus buttons to select up/down and a button for sounds too 🙂

A very cool prototype 🙂

He duct-taped and glue-gunned everything inside the box 😀

Koosha tests every components one by one.

He chooses resistors very carefully 🙂

There is something wrong with the seven-segment, Mama Ren helps and it works 🙂 But then Koosha decides to use LCD instead 😀

the LCD, the breadboard, and the arduino is glue-gunned to the box 😀

We’re testing the LCD and there are still some errors

so Koosha won’t go until it works 😀

Rezky is ready to continue another project: Automatic Pedestrian Traffic Light with Ultrasonic

Nafis is going to do the some project too

So Rezky and Nafis got paired up to do the project together 🙂

They learn and work better this way 🙂

Both test their own schematic

and help each other to debug errors 🙂

Nafis’ works

So does Rezky’s

Both works! 🙂 They’re given another task to add LCD and display “Pedestrian crossing” plus count down for next week 🙂

It’s been a long time since the last time Ren came to the class 🙂 Welcome back Ren and Mama Ren 🙂

Ren is working on what Rezky and Nafis are working

But the code won’t compile with ESPectro. So next time probably we will just use Arduino until we figure out what is wrong 😦

Mama Ren is a very dedicated teacher

She does some grading while Ren is coding 😀 Nice family 😉 ❤

There will be more interesting project for next week! 🙂
