ProCodeCG – BDV – codeMeetUp() #116 IoT Series Day #4 – 20 Nov 2017

Standard

The last day of ProCodeCG – BDV – codeMeetUp() #116 IoT Series 🙂

ProCodeCG - codeMeetUp() #116- IoT Weather Programming Series 4:4 - small

Today we made sure everybody could follow what have been learnt in the previous class

IMG_2544 IMG_2545

IMG_2546

After we’re sure that everybody can gather data from temperature and humidity sensor, we moved on to connecting it to the cloud

IMG_2547

IMG_2548 IMG_2549

Then we learned IoT & MQTT

IMG_2550

And experimenting with publishing and subscribing to MQTT 🙂

IMG_2551

We can do it from mobile apps too 🙂

IMG_2552

We can control (and being controlled LED) of any ESPectro subscribing to “led1” topic and can send and receive text to anyone subscribing and publishing to “pesan” topic

IMG_2553

IMG_2554

At the end we learned to continuously publish data to MQTT, and the next step is to send temperature and humidity data

IMG_2555

This us 😉

IMG_2556

Thanks so much all, thanks so much BDV, see you again soon with different topics 🙂

ProCodeCG – BDV – codeMeetUp() #113 IoT Series Day #1 – 6 Nov 2017

Standard

Today ProCodeCG and BDV started Day #1 of codeMeetUp() IoT Series 🙂

ProCodeCG - codeMeetUp() #113 - ProCodeCG codeMeetUp() #113 - IoT Weather Programming Series 1:4 - small

Today we learned some intro about IoT, take a look at some devboards and sensors

IMG_1346 IMG_1347

We used devboard from DyCodeX: ESPectro ver 3 🙂 It is available on Makestro Shop 🙂

IMG_1348

and then started to install Arduino IDE, drivers and ESPectro Libraries

IMG_1349

As usual, the beginning is always painful because it takes time to download the libraries, and do the setting 🙂

IMG_1350 2

We had kids in the class too 🙂

IMG_1351 2

IMG_1357

Everybody seemed to have fun, despite of the obstacles (different on every OS :D)

IMG_1352 IMG_1353

IMG_1354

The first group successfully installed ESPectro library and make the LED blinks, plus turned neopixel off. They were given task to make neopixel blink but time was up so we had to continue next week 🙂

IMG_1355 2

ESPectro32 is already available on Makestro Shop, to those who are interested 😉

IMG_1356

See you next week 😉

ProCodeCG codeMeetUp() #111 – Philosophy of BlockChain

Standard

ProCodeCG codeMeetUp() #111 🙂

IMG_8194IMG_8195

Philosophy of Blockchain by Prof. Budi Rahardjo 🙂

IMG_8196IMG_8197IMG_8198

Blockchain is not equal with Bitcoin

IMG_8199

Example of transaction

IMG_8200

how miner work

IMG_8201

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

IMG_8202

A chain will be created for each transaction

IMG_8203

The transaction will be hashed with certain criteria

IMG_8204

Example of simple hash

IMG_8206

A demo of transaction recording and creating chain in PERL

IMG_8207

creating hash that meets criteria for each transaction

IMG_8208IMG_8209

IMG_8210IMG_8211

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

IMG_8213

How miner work

Summary

IMG_8215

The audience

IMG_8212

We had long discussions 🙂

IMG_8216

Thanks for coming 🙂

IMG_8219

See you on the next ProCodeCG codeMeetUp() 🙂

ProCodeCG codeMeetUp() #108 – Exclusor – CryptoEconomics

Standard

Today, we had Founder of Exclusor, Tata Tricipta, sharing about CryptoEconomics on ProCodeCG codeMeetUp() #108 🙂

About Exclusor (from the WhitePaper):
“Exclusor introduces a new blockchain architecture designed to enable vertical and horizontal scaling of decentralized applications. Reducing energy consumption and high cost in block creation, thus lowering the customer fee unlike current blockchain transactions. This can be achieved by implementing new consensus algorithm and deploying consortium network model.”

IMG_4273

We set up the room while waiting for more people to come 🙂

IMG_4274

This is a very recent topic involving cutting-edge technology 🙂

IMG_4275 IMG_4276

About Lookats and its achievements 🙂

IMG_3834

The objectives 🙂

IMG_3835

“LOOKATS PROJECT is a small group of people that is currently creating a community through creation of events. we named it lookats project because of our passion to make a creation that is worth to be looked at. the urban lifestyle nowadays is really diverse and dynamic. however, it doesn’t stop us to create something new. we want to prove ourselves in everything’s happening in the world of creative industry or often said as trend” – http://lookatsproject.com/about-us/

The formula to be able to do business creatively and productively. This is the most simple and straightforward and brilliant diagram about business we’ve ever seen 🙂

IMG_3838

Some tips, tactics and strategy 🙂

IMG_3839

Well, there was MORE things we learned than what can be seen in the pics, there was lots of discussion and QA sessions after the presentation 🙂

This is lucky ones learned so much yesterday (two supermodel, one it-preneur rockstar, one procodecg kids, and two nerds: one programmer and one electrical eng student) 😀
