Thank you, yes, I have been thinking about asking you about programmed PICs. I am currently trying to source all the parts without paying too much shipping. If that is not too much hassle I may get a pickit2 and program it myself. If it's big hassle I may ask you for PICs to save some time. I'll let you know via email.
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!
At this year's MD&M West show, lots of material suppliers are talking about new formulations for wearables and things that stick to the skin, whether it's adhesives, wound dressings, skin patches and other drug delivery devices, or medical electronics.
The US Congress has extended an important tax credit for solar energy, a move that’s good news for future investments in this type of alternative energy and for many stakeholders in the solar industry.
