I spent a year studying propeller cross sections from the old NACA, which preceded NASA. I can just say that the issues are not simple. There are thousands of variations and the design of the propeller...

@Magemathician Get a T/C gauge, to start. They are inexpensive compared to alternatives and work at levels below 10 Torr where mechanical gauges won't work. I've used Teledyne Hastings type DV-6M-KF-16...

The red one you are showing looks like SPDT, not SPST. (3 connections in back.) But if you can accept SPDT, would this be okay?

@Juicer It sounds like you want to have your cake and eat it, too. You may use a car battery. But you may use something else. And regardless of its chemistry or topped off voltage (for example, \$12.6+...

I'm sure it's possible to create such a beast. In fact, it's why for-hire electronics designers exist -- to design what isn't already available as an existing commercial product. Likely a boost...
View ArticleAnswer by periblepsis for How to find current for Thevenin equivalent circuit
I understand that V_th is obtained by opening the terminals of theoutput, so that V_out = V_in R2/(R1+R2). The problem is that I don'tknow how to calculate the current flowing into the output...

@Juicer I'd recommend that you do the opposite of what you have been doing. Stop "try[ing] to limit the specs to what I assume is needed". Instead, write more than you think is needed. Things coming...

I can't help you with that lousy class-AB topology. It's got to change.
View ArticleComment by periblepsis on Why PALs has higher speed than PLA?
I vaguely recall that enahncement mode NMOS was used as pullup-resistors (depletion mode NMOS in the matrices) and this meant higher static dissipation vs more modern PAL/GAL devices. But I'm not sure...
View ArticleComment by periblepsis on How to get 4 bit output after comparison?
@yakubka I thought you wrote *"compare 3 4bit numbers" not 2. If all you want is to compare two, then just use the output of your comparator to operate a mux.

View ArticleComment by periblepsis on circuit that keeps its state even if power is gone
Exactly how much space, and what are its specific dimensions in all 3 directions? Is this about powering up in the last known state when the power last was removed? Or is it about keeping a state that...

This is a really good question for people like me who stay far, far away from GHz. I'm learning something new. Thanks for asking it! (Already +1 the question.)

Were these pinned out to use separate supplies for each color, you could reduce power that way, as well -- by supplying individual switcher-based supply rails for each of R, G, and B. Dissipation can...

@SRobertJames It looks like TAMB and TJ are outputs, not inputs. However, there doesn't seem to be documentation on them, either. TAMB, for example, seems to be a 1k resistor in parallel with a 1nF...

@SRobertJames If you want to put to bed these questions about your schematic, post up the netlist in your question. That will resolve all questions like this.
