802.15.4 Chip Comparison Sheet Update | Print |

Howdy everyone!

It's been awhile since my last post. Things are still hectic around here. The Michael Jackson Tribute concert unfortunately fell through. I think there were some management issues with the production company, but that was actually a good thing for me. I was probably the only one smiling when they announced that we were cancelled from the show. With the extra time, I've been scrambling to put the finishing touches on the product designs and get the shop up. I'm pretty excited about it, but its been much, much, much more work than I ever expected. I've also been busting some ass to finish off all of my tax returns since the Japan deadline is March 15th. Overall, the schedule has been really ugly lately. 

On the plus side, I should be getting more active on blog posts soon because I'm going to need to write a lot of tutorials on how to use the boards that I'm designing. The shop will mostly focus on WSN developers since from my experience, we're an often ignored group, yet vital to  bringing wireless sensors to the world. I won't get into it too much here since there will be a separate post about it when the shop is ready to go live.

Chibi v1.1 Schematics | Print |
Written by Akiba   
Friday, 08 January 2010

I just posted the Chibi v1.1 schematics. Apologies for the lag on everything. Things are so busy right now that I'm just struggling to keep up. I also need to create a project page for Chibi to house all the source code, schematics, and everything else thats going on with the project. It seems Chibi is getting more popular than the Zigbee stuff I'm doing. Guess I can understand since its much simpler and still accomplishes what most people want, ie: wireless comms. I'm finding it extremely useful for all the testing I'm doing. Here's some pics of the schematics and the pdf is at the link below:

Chibi on Github | Print |

Monday, 07 December 2009

Just wanted to give a quick heads up to everyone that Chibi is now on Github. I also wanted to give a special thanks to Gry who set it up over there and Benny who did the port to the Microchip MRF24J40 radio. The Github repository can be found here:

http://repo.or.cz/w/chibi.git

The repo also contains Benny's MRF port. 

It all started from the conversations inside this thread:

http://freaklabs.org/index.php/Forum/Article-and-Blog-Discussion/1380-chibi-for-MRF24J40.html

I'm really lagging on a lot of stuff due to getting the webshop set up, but once I get a chance, I'll integrate the port into a Chibi release package and also create a project page for it. 

 
Outline Summary of IETF Draft - Smart Energy Requirements for 6LowAPP | Print |
Written by Akiba   
Tuesday, 20 October 2009

After reading the recently uploaded IETF draft co-written by members of the Zigbee Alliance and IPSO, I thought it was a must-read for others interested in the Zigbee/IP effort, IPSO, or in the application of WSNs to smart energy. Since I know its a pain to read through IETF draft documents online, I thought I would post an outline summary of the document in bulleted form for easy scanning. That way, you can just look for the keywords that you're interested in. Just a note, I slightly reworded things or added comments (they're italicized) to put things in more laymens terms. Some of the jargon is meant for people that are well versed in wireless sensor networks, Zigbee, 6LoWPAN, and web protocols. If there are any questions, you should refer to the original document located here.

One good thing to note is that it looks like 6LoWPAN is locked in for Smart Energy and Zigbee will be integrated into 6LowAPP for the application level protocol and features. Anyways, here's the summary:

Google Powermeter and Zigbee | Print |
Written by Akiba   
Tuesday, 06 October 2009
Wow, just read that Google Powermeter bypassed the utilities and is accepting data directly from energy monitoring devices. The exciting thing for me is that the first gadget partner is the TED 5000 (The Energy Detective) which runs a Zigbee stack . This means that the potential is there for Google to open the API and collect data from individual energy monitors. Although the API would have nothing to do with Zigbee, the potential is there for a lot of new monitoring devices to start coming out and there's a good chance that a lot of them will also be using Zigbee. Hence I gotta start busting some ass and get the smart energy profile up. Nothing better than having an open hardware energy monitor running an open source Zigbee stack and sending the usage data to Google Powermeter :)
