Re: car Heater fan controller in NUTS & VOLTS

Hi Dorf, I don't think the type of capacitor matters too much in this design. The smaller ones, 2nF7 and 10nF, I would suppose is ceramic and the 330nF is a film type. The main issue is to get the values correct. :D Please note that the input and output terminals on voltage regulator 78L05 is revers...

Re: precise location in space

Hi Kurt, Your comment about the helicopter made me think of another way to get airborne pictures. What about one or more small Helium filled blimps with one (or more) camera onboard. You could then put out markers on the ground for reference and whatever automatic control of the camera(s) you want. ...

Re: Servo Robot Arm

Hi
What about using some form of counterweight balancing each part of the arm at the different joints?

Even if you introduce more mass, the balance will reduce the force needed from the servos.

Re: 800+ holes x3

Hi Matt, I don't know your budget or your drilling equipment, but from my experience you tend to break drill bits when getting tired. Stacking boards is a good idea if you use high quality drill bits and some form of stand. I might be getting old since this type of work doesn't appeal to me.. :D Thi...

Re: January 2006 issue

No, you're not. I usually get mine in the last few days of the month, or sometimes the start of the next. I'll not start waiting for the postman till next week. :D

Re: indicator lights

Edd & Chris, If you connect a neon lamp directly over the element, how do you see that the element is broken? I would suppose that the voltage applied in a normal ON cycle would be almost equal to 120V and above the turn on voltage for the neon. The neon will then be lit every time the element is ac...

Re: indicator lights

I just read all the ideas and got one myself. What if you made/got two small transformers, one transforming the on-voltage from the thermostat and the other transforming the current through the element. On the secondary side the current output could cancel the other in the normal condition. When the...

Re: Audio amp design

Hi, I'm no amp designer but I think I spotted a couple of errors. Q1&2 is turned off permanently by shorting base to emitter. Q6's load R5 is way to small to drive Q3&4, almost a short here too. So whatever Q5 & 6 are trying, you will not get anything through this amp. All (or most of) the resistors...

Re: I get no respect from the hinges on my laptop

It sounds like some form of static buildup when the connection through the hinges gets bad. The lube dries out after some time and the resistance increases. The relative air humidity can also be a problem if it is low. Here in Norway it gets very low in the winter, due to cold dry weather. Is it pos...
