Contact me for a minor bug fix to the remote decoder PIC ASM code in Gadget Freak Case # 192, the remote volume control. The BITST subroutine was rewritten for better noise immunity. Alternatively, you can get the updated BITST subroutine from the remote fan control in Gadget Freak Case #198. Don't use the whole program, as it will slow down the volume control response.
Alternate sources for the remote control to be hacked up:
Home Depot Westek Model # RFK306LC Store SKU # 567861
Home Depot (Christmas season only) Home Accents Holiday Model # RC-009A-1 Store SKU # 202620 (Same as above units, but has two outlets).
Lowe's SKU # 0357410 (Christmas season only) It is the same as the Home Depot Christmas version, but has a smaller remote, that is electrically identical to the remote used in this gadget.
Both seasonal remote control systems will work in this project, and both cost $10.
You're right, Jack. We're all so used to line-of-sight -- and nobody walking through that line. Seems like the whole world of remotes could be revampped on this principle. Our remotes -- which are in everyone's home by the armful -- still operate on 70s technology.
On of the interesting things about this device is that it doesnt' require line of sight and it goes through walls. With all of the changes we've seen in consumer electronics, the one device that hasn't changed substantially since the 70s is the remote.
I think the most interesting function of this gadget is that it remembers your favorite volume level. I am always fussing with my iPod and speakers trying to get the right volume so this would be great.
Sounds like he might have a captive audience for this for parents who want to control the volume of their teens' music or Xbox games from behind the scenes. Might help avoid some of the daily conflict. Sign me up!
Engineers at Fuel Cell Energy have found a way to take advantage of a side reaction, unique to their carbonate fuel cell that has nothing to do with energy production, as a potential, cost-effective solution to capturing carbon from fossil fuel power plants.
To get to a trillion sensors in the IoT that we all look forward to, there are many challenges to commercialization that still remain, including interoperability, the lack of standards, and the issue of security, to name a few.
This is part one of an article discussing the University of Washington’s nationally ranked FSAE electric car (eCar) and combustible car (cCar). Stay tuned for part two, tomorrow, which will discuss the four unique PCBs used in both the eCar and cCars.
