Here’s a sneak peak at my latest project — the RNET to Sonos Bridge. All coded using an Arduino and Ethernet Shield. What this little device allows you to do is control a Sonos device using any Russound whole house audio system that supports RNET sources. It allows next, previous, play, pause and I’m working on playlist access and support. Current track metadata gets sent to these keypads as a multi-field message.

I’m pretty much code complete but I’m running into a few memory issues… The Arduino only has <2K of available RAM that I can work with. I have an Arduino Mega (which offers 8K) on order to see if that solves things.  I think I can still optimize my code to make it work with the 328.

I’ll post more when I get it 100% stable.

Update: Got it working!  With about 500bytes left of RAM on the 328 chipset… this was a fun little project.  Below is a video:

Russound Sphere KLK-E6 Color Keypads

June 11, 2010 3 Comments

Russound has been my go to whole house audio solution for many years.  They offer solutions at many different price points and options.  They also integrate nicely with home automation systems like (Crestron, HAI, AMX, and Control4).  Recently, MAVROMEDIA became an Authorized Russound Sphere dealer and have just installed the latest E-Series system with the new KLK-E6 color click wheel keypads.   I’m throughly impressed — it’s like having an iPod in every room!    The E6 keypads bring a full color display that makes it easier to read across the room.

The main E-Series controller is a very beefy unit coming in at 4u high and is packed with options from doorbell chimes to paging to the ability to expand the system to 48 zones.  It also supports up to 12 sources which can be dedicated to specific rooms.  For example, you have an iBridge dock (iPod dock) in a bedroom.  You can reserve and display that iPod as a source for just that room.

If you are in the market for a whole house audio system that “brings an iPod to every room” then check out the Russound Sphere series!

Somfy ILT Control via HAI OmniPro II (wiring diagram)

Home Automation
June 11, 2010 2 Comments

HAI recently announced native control for Somfy ILT motors with the 3.4 firmware.  This means you no longer need to use RTS or Z-WAVE to control shades via the OmniPro II controller.    Last night I connected up and tested my friends system (also using Myro) and I’m happy to announce that HAI has hit another home run!  You get “real-time” feedback as well as the ability to set to a specific “light level”, like 50% (which is part way).

I have included a wiring diagram on connecting the HAI to the Somfy RS-485 ILT tap (also known as the Somfy SDN).  Then you just need to get the Motor/Group code and enter that into PC Access.  What I thought would be a difficult process of trial and error actually turned out to work on the first try!

Apple iPad Review

Electronics, Home Automation
April 8, 2010 5 Comments

I’ve had my iPad for a few days and compiled a Pro’s and Con’s list as part of my review.  I’ll try to be subjective but keep in mind that this device has been hyped a lot and may come across more critical than normal.

PROS

– Sexy, slick device — Apple is great at that.  They always have been.  They, again, have nailed it!

– Fast! — the iPad is very fast and responsive. I would say it feels faster than my 3GS.

– Screen is crisp, bright and vibrant — while the screen is not great for reading books, it is excellent for watching videos and playing games!  The pixel density of the screen is probably the best I have seen to date — as is the viewing angle.

– Bluetooth keyboard support — Apple is finally allowing you to pair a bluetooth keyboard with the iPad. This alone makes it easier to write emails and surf the web than the iPhone.

– Loud Speakers — the speaker on the iPad is LOUD!

– Multitouch Screen — the screen is very accurate and responds well to the touch.

– Amazing Battery Life — this is one of the most impressive aspects of the iPad.  The battery life lives up to what’s advertised!

– Love Native Apps — I find myself using services (Twitter/ABC) more because they offer native iPad apps versus hitting their website via the Safari browser.  I’ll take a nicely designed iPad app over a web page version any day.  However, there are some services that lose functionality in their native app.  This is bad, but not the fault of Apple.

CONS

– Device is too BIG — too big to take with you all the time.  I would have liked a small notepad (7″) sized iPad.

– Device doesn’t feel right in the hands — while it’s solid and looks good, it’s slippery and weird to hold.  The nook is the right size and the arched rubberized back feels soft and “warm” to the hand.  The iPad feels cold and fragile.  Which, I believe, if you drop, will do a lot of damage to the iPad, as well as mar it’s elegant aluminum finish.   I should also mention, the Apple case does change the feel and makes it a lot better to hold.  However, it does add $39 to the price of the unit.

– Screen is too reflective — it makes it unusable at times.  When will Apple make anti-glare glass cool?

– Screen smudges —  when the unit goes to sleep, you can see tons of fingerprints and swipes all across the screen.  Apple doesn’t even provide a cleaning cloth with the iPad like they do with all other devices they sell.

– Poor eBook Reader — screen reflections and brightness doesn’t make reading enjoyable.   I still prefer my nook over the iPad.  Shows you that a good single purpose device can beat a multipurpose device.

– Does too many things — really this is a con!  Maybe it’s just me and my A.D.D., but I can’t sit in one single application for a long time because I feel like I should be doing a lot of other things instead like; twitter, email, iPod, youtube, ABC Player, or surf the web.   I make the analogy to reading a book while someone else in the room is watching TV.  Sure, I can continue reading and ignore the TV, but the temptation to watch the TV always wins me over.  If I’m reading an eBook on the iPad, I feel like I should be watching a full episode of Lost instead.

– No accessible file system — you can’t place PDF’s in a folder and sync with your computer.  So you are stuck buying apps that may offer a solution.  In the case of PDF’s, the OS natively support them, however, there is no native reader… one solution is to email the PDF to yourself and access via the mail client.  Hacks like this make the iPad frustrating and unusable.

– Cost too much — at $499 for the low end unit, it’s too costly to justify for what it offers.  It does less than a netbook — $299 is what it should cost.

– Apps are expensive — maybe we got spoiled with FREE and .99-cent apps of the past.  Buying all the apps I’d need adds up quickly.

– Lack of native apps* — using iPhone apps on the iPad are painful.  While compatible, scaling makes them look pixelated and floating in the middle makes it hard to hold the device and navigate.    * This should be a temporary con as more developers release updates to their apps.

– OS was design for the iPhone screen size — you can really tell that the OS was designed for a smaller screen.  When you navigate on the iPad you find placement of the home button too far from the navigation bar.  Your hands are constantly moving around the screen.  The use of screen gestures could solve this problem in the future.  What works great on the iPhone causes UX issues on the iPad.   Apple did an excellent job with the iPhone implementation and designed the interface for that sized device. Refactoring the interface to support the larger real estate feels like an after thought.

– Weak WiFi reception — the signal is not as strong as my iPhone or MacBook Pro. Why?

Overall, I think the iPad is “good”.  The quality of the device is excellent.  Battery life is superb.  There are a handful of apps (ABC Player, Myro Control) which I love using.  I would rate it a 6 out of 10 whereas the iPhone is a 9 out of 10. I’m having a hard time seeing how people will use the iPad daily.   If I didn’t have my home automation control software, Myro Control (iPad version coming soon), I’d probably not use it as much because I always have my iPhone with me and when I’m at work or home I am near my MacBook.

I’d love to hear how you are using your iPad…

Just pressed submit and placed an order for a 16gb iPad… it’s been a pain developing applications via the simulator so I can’t wait to get this device in my grubby hands.   Did you guys order an iPad today?  Why or why not?  How do you plan on using it?   I’d love to hear — lurkers,  now’s your time to post a comment…

Niles MS220 – The Best IR Sensor!

DIY, Electronics, Home Automation, Home Theater
January 29, 2010 No Comments

It’s freaking 2010 and we’re still using IR, WTF?  Oh well… if you are looking to find the most reliable IR Sensor to connect to your IR connection block (used in applications where you want to put AV components in a remote area but still have control), I highly recommend the new Niles MS220.   I have used different units by Xantech, Russound, even Niles and the MS220 is the most reliable.   How do I know?  For starters, all the others I have used you needed to choose between CFL/Plasma friendly and not.  You’d get weird noise (the LED on the sensor would flash) from stray “IR” signals.   The MS220 utilizes a “smart” electronic circuit to filter out noise and works with all IR formats.   Check out Niles Audio for more information.
