    Backyard Landscaping

    We finally got around to getting our back yard landscaped. Arid Plant Designs did it, and they did a great job. We finally have something in the back yard other than dirt! We even have grass! I’m pretty happy having some grass for Kirin and the dogs to play in. I’ll post some better stills tomorrow.

    Home Theater Mac

    With Kirin’s increasing love affair with Elmo, we decided to bite the bullet and get a new TV. Our old TV we got when we first got married, so I figure eleven years is a good run for a TV.

    We were replacing an old 28” CRT TV that had a G5 iMac hooked up to it. The iMac was really starting to struggle with playback on full screen h264 movies, so we decided to replace that as well. To be honest, we actually set out to only replace the iMac, but we got side tracked…

    We decided to get a Mac Mini as the basis for the setup. The new Minis are a pretty decent setup for a home theater PC. Its small, its quiet, and it doesn’t look half bad in the living room. We got the Mac Mini home only to discover that I needed a new cable… a quick trip back to the store, cable in hand, home again. This time I was beset by our biggest setback.

    The old CRT TV only had a coax RF input. I had an RCA -> RF converterbox already, and was planning on just going from the Mini’s DVI port -> DVI to Video Adaptor -> RCA to RF adaptor -> TV. However, it turns out that the Mac Mini, and likely all future PCs, can no longer output a standard analog video signal. Why is this? Simply put, the MPAA has managed to con the graphics card makers, the PC makers, congress, and most of America into thinking that analog signals = piracy. Sigh.

    So no I was faced with either returning the Mini, or going full bore and getting a new TV. I needed a TV capable of either DVI or HDMI inputs. Pretty much any new flat panel TV these days has those inputs, so it was time to buy a new TV.

    We got a Samsung 32” LCD TV, got Jeff to come help hang it on the wall (out of Kirin’s reach!), and were finally able to hook the Mini up, and enjoy high def goodness.

    Apple ships most computers with a tiny remote, I got one with my last MacBook from work. For some reason, they don’t ship one with the Mini however. Seems strange, since a lot of people seem to buy the Mini to use as a home theater PC. Anyhow, I had a remote already, pointed it at the TV, and was off into Front Row, Apple’s media center software. Once I had iTunes and iPhoto hooked up to my media library, (Yay for external drives, and symbolic links!) Front Row saw all our music, movies and photos. Digitizing movies and putting them into iTunes is a bit of a lengthy chore, but its very worth it. I never have to go hunting for a disc when weKirin wants to watch Elmo. Just punch up Front Row, scroll through the list of movies, and press play.

    The realsurprisein all of this came last week when Hulu released their desktop app. I was pleasantly surprised when they announce that it would run on both Windows and Mac OS X. I downloaded it, installed it, signed in with my Hulu account, and in minutes I was watching shows from my queue right on the new TV. I’ll say this right now. Cable andSatelliteTV are dead. Within five years, the majority of ‘television’ will be video on demand, streamed to you over your only remaining communication utility: broadband internet.

    We had one small snag in the remote department. With two main applications, Front Row and Hulu, Apple’s simplistic remote couldn’t handle launching different apps. Fortunately, the people at iospirit make a really great program called Remote Buddy. It’s basically a highly configurable menu system that is controllable by remote, and is nice and large, perfect for a home theater PC setup. A little configuration in that, and I’m able to easily choose between Hulu and Front Row. The bonus is I can control a lot more on the Mac also. iPhoto is right there, and has some really stunning slideshows now. Having a 32” video picture frame is pretty cool. We have some Airpot Express modules around the house doing the Airtunes thing. However for someunfathomablereason Front Row doesn’t support streaming music to airtunes speakers. It works fine from iTunes, so Remote Buddy lets me jump into iTunes also with ease.

    Final touches involved getting a shelf to put all the electronics on.  We still need to get some conduits to hide the cables running to and from the Mac.

    All in all, I’m really happy with the setup.  I really like having the iPhoto slideshow up.  Its great to be able to enjoy your photo library on a day to day basis, without having to sit in front of a computer.  Just turn the slide show on and wander around the house.  We still don’t watch that much television, but what we do watch is now easy and more enjoyable.  Pretty happy with the setup.

    Kirin's Electronic Project


    Since kids imitate pretty much anything you do, Kirin is now getting into electronics projects. Luckily I saved all my kits from when I was a kid, so she doesn't have to steal my current toys.

    Open Letter to Apple

    Wow, it is really hard to register a complaint with Apple. Good job hiding any ability to contact Apple behind a maze of distracting options.

    Why does Apple reject an app like nin: access for ‘objectionable’ material, when the same objectionable material is accessible through mobile Safari, or the iTunes music store? If Apple wants to continue to push the iPhone / iPod Touch platform as a true mobile computer, it must relinquish arbitrary and artificial restrictions like this. This is my device, and I will put whatever content I want to on it. Up to now I’ve been able to do that without resorting to jailbreaking. If this is no longer true, I will have to look at the alternatives.

    I’ve been a pretty happy Apple customer for decades now, but the arbitrary social restrictions Apple is imposing on this device have me very unsettled. I will not be purchasing any upgrades to this platform unless this situation changes.

    I do not need Apple to protect me from the evils of the world. Please leave that up to parents and adults.

    You cannot censor the internet.

    Sincerely,
    Mark Fischer

    Putting stars on our ceiling

    Playing around with silly electronics again. This time the idea is to put twinkling stars on the ceiling of our bedroom. I’m using two TLC5940 chips to drive LEDs. The chips are capable of 16 channels of PWM, so the stars can fade on and off nicely.

    Step 1 was a proof of concept. Could I figure out how to hook up one of these chips to an Arduino, and get it to fade some LEDs on and off? Fortunately, the Arduino community is amazing, and someone has already written a fantastic library for this chip. (Thanks acleone!) The documentation on how to hook the chips up is all defined very nicely in the comments of the example programs in the library.

        Basic Pin setup:
        ARDUINO                                     TLC5940
       ------------                                 ---u----
                 13|                          OUT1 |1     28| OUT channel 0
                 12|                          OUT2 |2     27|-> GND (VPRG)
                 11|                          OUT3 |3     26|-> SIN (pin 7)
                 10|-> BLANK (pin 23)         OUT4 |4     25|-> SCLK (pin 4)
                  9|-> XLAT (pin 24)            .  |5     24|-> XLAT (pin 9)
                  8|                            .  |6     23|-> BLANK (pin 10)
                  7|-> SIN (pin 26)             .  |7     22|-> GND
                  6|                            .  |8     21|-> VCC (+5V)
                  5|                            .  |9     20|-> 2K Resistor -> GND
                  4|-> SCLK (pin 25)            .  |10    19|-> +5V (DCPRG)
                  3|-> GSCLK (pin 18)           .  |11    18|-> GSCLK (pin 3)
                  2|                            .  |12    17|-> SOUT
                  1|                            .  |13    16|-> XERR
                  0|                          OUT14|14    15| OUT channel 15
       ------------                                 --------
    

    Two TLC5940s on a shield

    Once I had a single chip working on a breadboard, it was time to plan out a more permanent board to house two chips.  Two chips gives me 32 stars, which I figured was enough to start with.  In order to fit the chips on the shield, I changed the transfer mode from SPI to bitbang inside of tlc_config.h, this let me just move from pins 11 and 13 over to 4 and 7, and let me squeeze in the TLCs right next to the arduino connector pins.

    I changed the suggested resistor on the chip from 2kΩ to 100kΩ.  The white LEDs I’m using are just way too bright with only 2kΩ of resistance.  100k knocks the brightness down to an acceptable level.

    Next I need to start getting serious about wiring up a bunch of LEDs and start sticking them to my ceiling.  I also have to figure out an elegant way of bringing in 30+ very thin wires and connecting them to their appropriate pins.
