Today we will test object detection with darknet and darkflow configuration

photo6150062494501152961

It of course took a lot of effort and resources (in terms of time and computational resources :D)

photo6150062494501152962

Every participants are free to decide darkflow or darknet. But both implementations are expected.

ProCodeCG – BDV – Technical Series #8 – Machine Learning Object Detection with YOLO – 1 April 2019 – Day #1

Standard

Our training about Deep Learning and YOLO for object detection, Day #1 πŸ˜‰

IMG_8664 IMG_8665

Like usual, the first day of the workshop is about basic theories and then installing saga πŸ™‚

photo6127299760537840124

Our target for today is installing Python, virtualenv, tensorflow, requests, numpy, cython, opencv, and nmv

photo6129897330988656723

but since there are lots of operating systems and configurations, we could go as far as installing virtualenv and tensorflow and for some: hello world in tensorflow

photo6129897330988656722

The complexity of the tasks is shown here πŸ˜€ *look at the faces LOL

ProCodeCG Kids Regular Coding Class – 2 Feb 2019

Standard

Just as promised next week, today we made lots of progress πŸ™‚

IMG_4788

Agham has added a stop sign for the school bus so we will get socre when it reaches there

IMG_4765

IMG_4802

Agham carefully chose and edited the assets of the game

IMG_4810

The game is looking very nice, what we have to figure out next is to print score and make the bus comes from the right side of the room each time leaves the room from the left side

IMG_4817

Djalu learned how to create apps today πŸ™‚

IMG_4766

Djalu is signing up for a coding competition so we’re preparing for it

IMG_4805

It took some time to switch from Python to this drag and drop programming πŸ™‚

IMG_4824

IMG_4829

Djalu’s first app πŸ™‚

IMG_4830

Hafiz’s task for today is to create a jumping dinosaurs game like Google’s (when there’s no internet connection) πŸ™‚

IMG_4767

Hafiz always do task in detail πŸ™‚ Look how he finds references and make the sprites as close as the real ones πŸ˜‰

IMG_4780

Finally done! We just need to add score and make the cactus appear randomly πŸ™‚ Well done Hafiz πŸ™‚

IMG_4809

Captain on Duty: Faris

IMG_4768

Faris is doing research on Machine Learning using Python Library to generated random faces

IMG_4781

The codes

IMG_4800

random process

IMG_4841

the international conference publication he’s reading today

IMG_4842

These faces are generated by an machine learning algorithm *isn’t it scary that these faces not really exist; but generated by a machine?

IMG_4843

Aidia and her big awesome project! πŸ™‚

IMG_4769

The mouse on the right will move across and when 3 ultrasonics sensors detect it, it will control the traffic light and then open the gate πŸ™‚ The awesome support from the family (the mom who created the maquette and the father bringing it to the class and bring it back after) that makes this incredible product possible πŸ™‚

IMG_4775

Aidia is a very busy little girl, she had to go right away after the class to a dance performance that’s why she looks so cute today with that hairdo and make ups πŸ™‚

IMG_4799

Sam, making great progress each time. Like always πŸ™‚

IMG_4770

He added more features to the app and he had successfully solve the problem with the sound πŸ™‚

IMG_4790

Fadhlan is building a new robot today. The mapping robot

IMG_4771

Lots of components to be tested and assembled

IMG_4776

After making like 4-5 robots from scratch, today Fadhlan actually followed the manual instructions πŸ˜€

IMG_4784

IMG_4791

and get much better results πŸ˜€

IMG_4792

We tested the Arduino Leonardo today and it worked fine

IMG_4814

we also tested every ultrasonic sensors

IMG_4816

next week we will process the input from all 3 ultrasonics

IMG_4822

Look at the mess πŸ˜€

IMG_4826

Al was given the same task as Hafiz πŸ˜‰

IMG_4773

Al gave different looks to his characters

IMG_4777

so typical of Al πŸ™‚

IMG_4793

IMG_4798

Done but still need improvements πŸ™‚

IMG_4821

Faishal is working on the same thing as Djalu

IMG_4774

IMG_4779

IMG_4795

Faishal’s first app

IMG_4803

He started exploring the block of codes

IMG_4820

IMG_4825

Figuring out how to set timer for the splash screen

IMG_4828

Sulaiman worked on the locker project

IMG_4778

IMG_4794

IMG_4796

We even borrowed Aidia’s book to find ideas πŸ™‚

IMG_4797

IMG_4815

IMG_4819

Farrell got the new components to explore today: joystick, gyro and micro servo

IMG_4782 IMG_4783

IMG_4813

Lots of work to do but Farrell spent some time to help Agham πŸ™‚ Thanks Farrell πŸ™‚IMG_4806

 

Yogi is working on the same game for weeks, that amazingly looks like a real game

IMG_4786

He put HUGE effort to the game and pay attention to EVERY details

IMG_4801

The movement, the animation, the look, the feel is very real

IMG_4811

the key is that the game is not using only drag and drop coding, but mostly written codes. Β Complicated lines of codes πŸ™‚

IMG_4823

Today Yogi has successfully created what he wanted to do for weeks: make a menu controlled with arrow to select πŸ™‚ Impressive work today, Yogi πŸ™‚

IMG_4832

Here’s some of the codes

IMG_4836

IMG_4837

IMG_4838

The result is unbelievable πŸ™‚ Next to do: adding scores and fuel stats πŸ˜‰

IMG_4839

The best about this class is the kids will gather up together and help each other when needed πŸ™‚ This is when a toolbox was turned upside down and all of it contents are in the floor, kids in the class come and help πŸ™‚ Very nice πŸ™‚

IMG_4827

Can’t wait to see them again next week πŸ™‚ Until then πŸ˜‰ ❀

ProCodeCG – Young Scientist Competition – Coaching – 20 Jan 2019

The first Young Scientist Competition Coaching to prepare the participants for the international competition πŸ™‚

Fadhlan had to present and demo his work

Time for presentation

IMG_4001

And the robot needed some tinkering to make it work again because Fadhlan had built it from scratch

IMG_4002

The judges

IMG_4007 IMG_4008

One of the judges: Pak Janto V. Sulungbudi, lend us 18650 awt batteries, he helped installing the batteries too πŸ™‚

IMG_4009

Still not working, must be the wiring or bad wires

IMG_4010

So we had to delay the demo until we make this work πŸ˜€

IMG_4011

We did everything: change the power supply, add it, connect it in parallel, in serial, divide them and all, still not working. Everything on the breadboard that connected to Arduino works, but the wheels just wouldn’t.

IMG_4013

We checked the wheels and the DC motors by giving power directly and they worked properly. we suspect the motor controller but we didn’t bring any spares.

IMG_4014

We worked for hours. After lots cups of coffee and tea πŸ˜€

6ff7b061-f3a2-43af-8641-897d3df048aa

We did soldering, and unsoldering, and then it left us with one possibility: wires connecting to the dc motors. And after we changes them, it works! πŸ˜€ Fadhlan glue gunned the connecting wires to secure them and apparently it burned the wires and make them stop working (next time no glue-gunning connecting wires!)

Back to the judges

c360b605-0542-4326-8fdd-688198f8351a

Ok the robot worked nicely, only the ultrasonic sensor didn’t give any readings. Must be the wires πŸ™‚ But at least now we know what the problem is πŸ™‚

10785404-4c46-471e-9ff1-c2b1fcb92b8d

Judges gave suggestions on what to do to upgrade the robot, and we have to make weekly reports. This is a very valuable experience and a great honour for ProCodeCG to be a part of this awesome event. We’ll be working on this for a year, if we make it to the next stage, we’ll see πŸ™‚

Day #3: building curriculum to teach kids coding πŸ™‚

We reviewed some reliable references like international journals and books to compare the most suitable curriculum to be applied

IMG_3727

We started to write curriculum documents and reports

IMG_3730

And did lots of brainstorming to make sure we did it right

IMG_3731

These teachers and principals made a great achievement today and they are ready to return to the school bringing the new skills to be implemented there

IMG_3732

IMG_3735

It is an honour to be able the meet these great educators πŸ™‚
