• Jsoknit proof of concept

  Daniel Sikar • 02/19/2016 at 20:31 • 0 comments

  Documentation and code added to the github jsoknit-proof-of-concept repository.

  Current status. All working from the bluetooth radio and beyond. On the user side, Android code still to be written. As Al Pacino told Marlon Brando in The Godfather; "We'll get there, pops."

• Bluetooth module

  After a period of hibernation, we are once again moving forward. The Bluetooth radio is now working. Instruction to be found in this Github reposiitory. Stay tuned.

• Filling the AKH (Android Knowledge Hole)

  Over twenty days gone without a log entry and here is the pulse. I am currently working on Android Programming so no change, really. It is plain Android-slanted Java at the end of the day and I like it. Android Studio is a pretty good platform if anyone asks me, and the iterations are quick. I am expecting the v0.1 release this side of xmas. Basically it involves JSON parsing and rendering objects such as buttons, sliders and textboxes at runtime. Then an early spring clean still in order, hive off some parts on the project to other mini-projects and so forth. And that is the news and weather brought to you by Jsoknit.

• Still working on Android

  Daniel Sikar • 09/28/2015 at 21:09 • 0 comments

  I invested some 7 hours so far getting to grips with Android Studio and layouts and should be able to post some real mock-ups within the next couple of weekends. I also had another go at Fritzing and it looks manageable enough.

  As far as the Jsoknit project goes, the more perspective I get on it, the more pollution I see. The solution I envisage is to move everything that does not pertain directly to coding Jsoknit to other hackaday.io projects, i.e. move thermocouple building to another project page and so forth. In the end, it should be just about defining the Jsoknit interface for a given embedded device. The Android code should go straight to Github. Anyway, onwards and upwards while I am in the realm of the living.
  

• Working on Android

  Daniel Sikar • 09/09/2015 at 13:22 • 0 comments

  Did not managed to finish interface. Still getting my head around Android Bluetooth - a few steps closer to dealing with input and output streams. Android Studio has feature rich debugging so hopefully will be out of the woods before the end of this month.

  Other developments, will try to make a start on the circuit, printed some notes by Texas on laying out PCBs for high frequency devices. At low baud rates I am not sure my device falls into this category but I don't have the knowledge or tools to monitor the actual communication between the two Bluetooth radios so will work on the assumption it is.

  Finally, I was thinking about bringing in Fritzing to document the actual Uno - BT0415 setup to make it easier to replicate in the future.

• Two-way communication

  Daniel Sikar • 09/06/2015 at 16:50 • 0 comments

  Managed two-way communication, as always it was indeed a timing issue. Project now has 0.5k views <fireworks>. Building up some critical mass. Hoping to have basic interface up and running by tomorrow - have set the day aside to work it out.

• What is happening/happened this/last week

  Daniel Sikar • 08/31/2015 at 13:37 • 0 comments

  Managed:

  to get two way communication going between Arduino Uno and Android 4.3 via BT0415. Message received on Arduino then echoed to serial monitor and all good. Message sent to Android does not always make it across and when it does comes out as gobbledygook so will need further processing i.e. byte by byte parsing, assembling into readable ascii characters, etc. About the message not making it across, previous experiments suggest it is a timing issue e.g. strategic delays need to be added to allow for protocols to ready themselves.
  

  Did not manage:

  to write basic app to query Arduino Uno (a.k.a. Jsoknit compatible device) and receive interface definition.

  Road map for the week:

  sort out two way communication and complete the basic app.

• What's happening today

  Changed project name for the 2nd time. Now we are Jsoknit (pronounced "jasonet"), like knitting with JSON. I thought maybe jsonet but there already is a javascript server-client communication protocol using JSON that goes by the name. Other than that, got this nice email from Hackaday:

  Dear Daniel Sikar,
  
  Thank you for participating in the Hackaday Prize. One of our goals here at Hackaday with the Prize is to encourage good documentation. Your documentation on Jsoknit qualifies you for a commemorative Hackaday Prize T-shirt. Congratulations!
  
  Please fill out this form by October 31st in order to get your T-shirt!
  
  Email Jasmine if you have any questions.
  
  Thanks again,
  The Hackaday Team
  

• Thank you for entering the 2015 Hackaday Prize

  Daniel Sikar • 08/24/2015 at 14:22 • 0 comments

  Dear Daniel Sikar,
  
  Thanks for participating in the Hackaday Prize. We had a great time looking at and admiring your projects! Unfortunately, JASONette Interface was not chosen to advance to the next round.
  
  But - that doesn't mean you should stop working on it! We'd love to see this project continue being worked on and added to on Hackaday.io.
  
  Come hang out in the Hacker Channel, get feedback and encouragement and push your project. Maybe you'll enter it in another one of our contests.
  
  If you have any questions, please email Mike, Sophi or Brian.
  
  Thanks again for being a part of this,
  The Hackaday Team

• This week's TODO list
