I've seen home-made products here and there controlling dampers. It lets you fine tune air conditioning to save money and make things nicer. But what kinda hardware exists for turning on/off dampers? Here's why. We have a wood furnace here, in addition to the gas. Most of the time it's on...

Well, I'm using OWFS, don't have the patience (or background) for C-programs and such; I just cut off the switches and presumed them non-existent. If I want trouble-free switches, including a count of switches that matches my application, I'll just get a few discrete PIO's and let'er rip...

My trailer's using a single temperature sensor and controlling a pair of fans. It helps with the heat- the side that's unfinished (the front) faces the sun, so it's a losing battle. (No insulation) But it works great. Yet I can't help but wonder and theorize how *early* I could turn on the fans...

I have switches connected, according to the schematic (3.8) it should be PIO.0-PIO.2, but nothing at all happens. I've tried sending "0" to the PIO so they're non-conducting, but that clears the LCD, suggesting to me the schematic might be wrong. No one seems to have ever done this...

Still no joy...am I the only one to ever use these switches?

I've never worked on a Mac (especially since they got a lot more open-source friendly) but is it possibly OWFS (OneWireFileSystem) is a choice for you? The beauty is that all the initialization of the hardware is done for you, and all the data is there like so many files in the...

This one's mine; I'm building a trailer from scratch because I hate the classic "RV" that's made of cardboard and contact paper...and I'm taking my computers along with me for the ride. That's what makes me a technomad! (For more on Technomads, see http://microship.com/) After some fooling...

Pretty spiffy! About the touch-switches; can these be had for a decent price in America? Is the color-fade and lighting on them built-in, or would I have to code it? I like the idea of the no-backlight idea; mine's on all the time, but I don't think it's a probem. And, after so many years...

I'm just about to use the three extra lines that are available on the LCD; I have a 4x20. The plan is to hook up push buttons and read them under program control. The idea is to build a buffer with (doing the math..) 16 lines of data. with the first "screen" of four normally showing. When...

Oh, be careful whatcha ask for, bud. :blink: But yeah, I've only needed it twice, but the processing speed was fast, and the parts were well-built. (I've had issues with mounting holes, but I'm using them without a case, and that's not the way they were designed to be...)

Well, I think they're *fabulous*. There are some details I've had with mounting holes and tiny little details, but they're well made, solid and dependable. I'm using a handful of them now; a 6-port hub, HVAC monitor, relay board, a multi-sensor board, and an LCD. Right now I have a handful...

Ahl ok. I ferreted-out a coeffecient that got me within .1V; I'll try your new numbers when I get the sensor-net re-assembled. I got the equipment-room cooling loop, and the power-management loop worked out, with a glorious display on the LCD, but now it's time to start installing the stuff so...

I must be the "other" guy using this board. :( I'm also finding no docs for it on the website. I'm running the "black" and "red" lines from a PC power supply to the "A" and "GND" terminals on the device, and I'm putting power on the device through a 6-port hub. 11.55V on the terminals shows...

One of the 1-wire devices is the DS2436 "Battery Monitor". It's intended for use in cellphones, etc, but what if the cells are a little larger? For example...a battery bay with 3, 1200CCA batteries powered by shore power? ;) As I understand it, it's merely sensing the...

OK guys, I've got it. It was one of those "think outside the box" solutions, just as I was beginning to like the taste of cardboard. I tried sending *21* or more characters, in my case, by echoing them to the OWFS file "message". Every time, it put it on line 1 as anticipated, but then went a...
