Last weekend, Electronics for You (EFY) folks organized a very interesting electronics related conference (called as Electronics Rocks) at NIMHANS convention Center Bangalore. I got a chance to attend the conference after a long time. The primary objective was to attend the hands-on workshop organized by Kits and Spares folks on their Mango Pi development board as I wanted to get more insights into these embedded learning kits, which was coming as a free item along with the workshop. Though workshop was a major flop show (details below), there were many interesting takeaways.

As mentioned in my previous post on Embedded learning kits, I spent quite some time surveying development boards that can be used for educational/learning purpose.  I started off by looking into the latest Beaglebone black board (by Texas Instruments) with ARM 335x Cortex-A8 processor, which doesn’t come with TI DSP for media processing. Upon conversation I understood, there are applications available, which can do decent graphics processing. However for higher end graphics related stuff, Pandaboard still works better as it comes with multiple media interfaces. Definitely there is also a 4 times price difference between these two (Beagle comes at USD 45 v/s Pandaboard at 174 USD). On business side, I could observe all these boards are sold by multiple re-sellers, who were having different stalls in the conference. Considering the price point and target audience, it perfectly makes sense to take re-seller option.

On the electronics components side, I could see many vendors who were showcasing their list consisting of various parts. Had some conversation with folks from RS components, who are into component selling from almost all the major semiconductor manufactures.  They also seem to have a hub of interesting embedded projects in platform called Designspark, where design engineers can can exchange their ideas and create projects. Along with components, there were also many vendors demonstrating debuggers, tools and embedded design services capability. The debugging space is definitely interesting, but I was not paying much attention as it makes sense only for devices with at least a JTAG interface, which was not my area of focus. From governance side, erstwhile Indian Semiconductor Association (ISA) has changed their name into Indian Electronics and Semiconductor Association (IESA) with responsibility of promoting electronics ecosystem in India.

Coming to Mango Pi workshop, it turned out to be a major flop. During initial promotion they mentioned this workshop as “Build a wireless robot in 60 minutes” using Mango Pi board and mentioned participants can take away a board at the end of the workshop. I was excited about it and registered for the session by paying extra 1500 INR, specifically for this workshop. It was a total chaos where they messed up everything starting with schedule. I was supposed to attend 11:30 AM slot, but they asked me to to attend the 12:30 PM slot due to increased number of participants . I waited for almost an hour, where there was a big queue and people were flocking into a small room. The workshop co-ordinators were relatively junior guys, who couldn’t manage this chaos, eventually mentioned they will do the next session in a bigger room located upstairs.

The upstairs location was an open one, where the sound system was not at all conducive for a workshop environment. On top of that, workshop speaker was of very low quality, neither he was good in communication nor he had much idea about technical aspects. He went on demonstrating building robots with totally a different kit (where Mango Pi board only plays a part), where there were other components like Arduino board, RF sender and receiver etc. I got totally irritated with this poor organization  ended up leaving the workshop within 15 minutes. When they organize an event of this scale, proper attention to be paid as it creates a strong impression on the whole product that is getting demonstrated. Executing it in such a ad-hoc manner has resulted in nothing short of a disaster.

Apart from the items mentioned above, there were a series of talks happening on multiple themes which I couldn’t attend due to personal time constraint. Probably I should plan and attend those sessions next time. Overall it was a decent conference, which provided me deeper insights into many aspects of embedded systems, educational kits, open source, Linux and related technologies.
