I need either a spice model, or a link to a website containing the internal circuitry (so I can make my own spice model) for a Schmitt NAND (4093, though the 74xx series equivalent would be OK too). Its not on the datasheet as I have already tried that.

Thanks for your help

I'm an electronics hobbyist, or I was many years ago. I'd like to make smaller circuits. Are there ICs that have a mix of components or common elements that hobbyists might use? Like resistor/capacitor arrays? Or elements like several op-amps on one IC? Or a RF signal generator? My question isn't so much do they exist but how do I find what I'm looking for among the thousands of ICs on the market. Alternately, how do you go about reducing the size of your circuits? Can you recomend any online tutorials that discuss space efficient circuit design?

Our architect suggests using rockwool along with some other materials but we are concerned because we've read some things about rockwool and the possibility of it causing health problems.Could we use something more environmentally -friendly?

I have made a radio crystal by cuting a quarts crystal in slivers lengthwase. I then made the cats whisker about one inch long from bronze welding rod and mounted both cats whisker and a slice of crystal on a thick piece of plastic. I then cut the element part out of a car headlamp to get a bulb. I then made hydrogen gas by using the Hoffman voltaic electrolisis proses. I inserted the gas into the bulb under water and then plugged it with the plastic disc on which the crystal and cats whisker was mounted, making provision for the anode and cathode wires to come out the bottom. I found that it does work as a diode but it has a very high electrical resistance which is unsatisfactory. I must either increase the hydrogen preasure to 3 atmospheres or use another gas that will cause ionisation. I could use a bicycle pump on a mounted bicycle valve but what bulb will withstand this preasure? I cannot obtain Xenon gas, so what other gas could I use as a alternative?
