Hi, thought I'ld throw in my two cents. What u want here is antialiasing. What everyone said is essentially correct, packing in more pixels is not the economically feasible way to go, even though it is the "pure engineering" solution. Antialiasing is a smoothing technique that takes into...

I emailed Heat+Cool U and they said they will honor the warranty if Goodman won't replace a part. Guess u bought from the wrong place. ;) A kilopost eh? Of course u mean 210 posts, right. We need 4 more after this one to reach the quarter kP point. -- There are 10 kinds of people in the...

Nah I doubt that turbine had enough torque to drive a boat. Better to have it power an electric boat motor. (something i've always wanted to do.) Hey smoked, how's that Goodman holding up? Good heat, no failures? We're thinking of buying several for own house and properties.

Now that's what I'm talkin about! I bet that gen just laughed at hail storms. Sucker was designed to take high speed shrapnel and blast. Alt, u know what they say, if u want something done right...

Alt if u can live a few more years u should apply for the job of Starship Engineer. :-D

Wow, that's an accomplishment. Just the kind of "damn the torpedoes" type on install I might try. Like how I'll spend 30 minutes writing a script so I won't have to type a 10 second command line.

Only 200 watts? I thought u needed a lot more power than that to drive the heating system. There are 300 W DC motors on eBay going in the $25 range. They're Krollman electric scooter motors.

Hey man, don't try to blame me! :-D

I saw some 8 HP Briggs & Stratton motors on eBay that ran on 12 - 48 volts. They were really small for the power, measuring only about 6" diameter. I was thinking about buying some to build an electric car but I haven't won the lottery yet. They cost $399.

Sorry I've been away a bit. Been having computer trouble. Anyway, does anybody know of a good tuturial on how to use Spice? I didn't find anything with the software links. It's like they all assume u already know how to use it or why else would u be downloading it. Once I get it working...

Thanks for those links. I downloaded Spice+ but it's a command line program and there's no documentation on how to use it. I have no idea how to make a Spice file. I got Aim-Spice too but it also seems to want a spice file. I was hoping for something with a CAD like drawing interface to get...

I just had another idea. Set up a small radar unit and aim it down the hole. It should ignore all the junk in the way and give u a good relection off the water surface.

I've been thinking about various modeling techniques. I'm pretty sure I can eliminate the the 3rd D because the shape I need shouldn't have any voltage drops in that dimension. It's planar, meaning I can divide it up into as many planes as I want and each plane will be receiving the exact same...

Heck at 5c a kWhr u should build a coil to power the WHOLE WORLD, just like Tesla wanted to do. This inspires me as to another way to find the well water level. Float a coil on the water level and fire up a huge tesla coil on the surface. From the induced current in the well coil u can...

Heh, I was wondering when somebody was going to ask that. The truth is, it's sort of a secret. It has to do with the applications of shaped resistive bodies. If I say too much somebody'll surely rush down to the patent office and screw me. :-D chris

No no no, that's not nearly engineerish enough. Even cave men had extension cords. V1BLL please build a large tesla coil designed to direct flux primarily into the southern Ohio region. I will correspondingly build several receiving coils to receive said 5 cent power.

Right out of an episode of "Lonesome Dove". ;-)

Great thread, classic. Alternety, another way u can control ur flow rate is by running the motor output through an infinitely variable transmission. That way the motor only cares about on/off and runs at constant speed. Controlling the IVT lets u vary the pump rpms and thus flow rate. chris

er, 9V.

U can combine a zenner and a relay to get the effect. Connect the light line to a zenner with say 12V breakdown. The zenner should then connect to the coil of the relay. This way when the light is "on" the zenner will be energized and the relay will be energized. Then when the light is "off"...
