searching for one thing and stumbled upon the last responses...

Thanks! 8)

I actually came across a couple of old ISA boards with tons of header pins on them cleaning out a shelf at work... Can't argue with the price!

Thanks dtief for shedding some light. #1. I agree. The A/C in my apt pretty much just wastes electricity to begin with... I could never get my place colder than 76 or so degrees, and that took a long time. I utilized fans and opened windows at night, somehow I went from $100 for July to $60 for Augu...

HVAC design questions

I put off my HVAC thermostat project since I barely ran the barely working A/C this summer. I've had to run the heat a few times, time to get this thing going. I have some questions I haven't found an answer to or want opinions on: *I am replacing one of those generic round honeywell heat/cool auto/...

Cutting clean holes in enclosures

I have a plastic enclosure I want to mount a dsub connector on. its one of those Radio Shack 2x2.5x5 plastic boxes. It is funny how they don't have much and its usually overpriced, but they have cheap enclosures... Anyway, I haven't worked with these things for a very long time and I remember my wor...

Economical Electronics article on the front page

I read the Economical Electronics article by Bryan Bergeron, Editor. It appears the editor needs an editor himself. There are multiple typo's/ill-formed sentences. Doing more with less is nothing new those of us work in electronics. how about this: While many of these discount suppliers offer second...

Digi-key has been nothing but awesome for me. Jameco I have beef with, not just because it takes a week for ground shipping coast-to-coast (it should be expected) I ordered 1 pack of 5 RCA phono plugs for $1. When I recieved my order, i looked on the packing list, in the units column everything was ...

I saw an interesting PSA for digital TV. It stated only HIGH POWER stations will be forced to move to digital. Low power TV will remain analog. This could make for some interesting pirate stations in the future. I can only hope i'll find a station like in the movie "UHF" :grin: I need to come up wi...

lol, what are they doing still teaching VB6? I thought only 3rd world programmers still use it :lol: I believe that's what we used when I was in high school about 9 years ago. Even then, all they taught us was how to read a text file and perform simple logical operations. I would recommend upgrading...

I took the cover off when I got home, and lo-and behold, I see 4 magic characters: T87F I typed in the part number, T87F2584, into google and got a honeywell thermostat cross reference spreadsheet that gave an equivalent replacement model. The model is mentioned in the T87F family datasheet posted a...

If they REALLY wanted to reduce red light accidents, increase the time for FOUR WAY RED to about five seconds. No cost except for the guy to come out and program the "pause" one time. And this could be scheduled during regular maintenance windows. This is slightly OT, but what is actually in those ...

Vintage thermostat question

I have an old analog electromechanical thermostat in my place. I'm guessing it dates back to the mid 1960's. I've been thinking of designing my own replacement that's tied into my computer and will let me read and control it remotely over the internet. My thermostat looks practically identical to th...

dyarker is correct, generator torque is proportional to the amount of current delivered to a load. If you had a DC motor you would expect to need more current to turn a tighter gear for example, same thing here. This is also true of the A/C compressor when turned on (I had trouble understanding tha...

Now if you make the electricity to electrolyze the water off-board the car like grid or generator power then mix, of course one would expect a significant effect and reduction of gas needed. However if you generate that electricity in an alternator powered by the very same engine you are using to s...

Electrolysis car add on

I was web surfing and came across this somehow, http://water4gas.com/2books.htm he's got some ridiculous claims, such as a 75% to 200% increase in MPG. I find the design somewhat comical. It's a mason jar with electrodes and a few tubes. You'd think a professional would have higher quality illustrat...
