Hello,

"Hi, are there chips that can be done quite quickly that have a market?": I feel that the problem here is not the possible market: we are now in a very preliminarier-than-preliminary stage of chip-making and chip-design. The 555 was chosen as a target not only because of its symbolic perspective, but because this is what can be now done quickly with the knowledge, tooling and resources we have right now, and still can "blink and beep". For example, USBtoIEEE488 would require a USB device controller with significant complexity (data buffers, state machines, endpoint management), and implementing the USB stack needs at least a small MCU (that is complex in itself), not to mention the clock generation, clock-recovery PLLs, high-speeed transcievers etc. needed for USB PHY. Developing this would take at least months of simulation only for the logic (and maybe much more when we consider the analog and mixed-signal part, not to mention the validation...). And I'm pretty sure that implementing an USB device core on silicon will bring in the patent lawyers from USB-IF

 and virtually all IP core vendors...

Regards,

Ferenc

So a 555 has no market as there are cheaper options. Chips need

to be tested and packaged.

But maybe there is an expensive chip that is not longer manufactured

while there is a demand.

I can only think of some IEEE488 controllers made by National Instruments

for ISA bus, but there are USBtoIEEE488 adapters around based on
micro controllers which seem to be good enough.

We need a chip that is lacking if it is missing it is a show stopper for

some business / manufacturing machine.

Any ideas?

Cheers,

Ludwig

 i can emphasise that getting the word out to as many people as you
can, and asking those friends to also pass on the link to their
friends, reminding them as much as possible with as much "new stuff"
as possible, on as many possible channels as possible, is the way to
get a campaign to succeed.

 david if you and the team can think of "new things to announce every
few days", that gives you a reasonable (and non-repetitive) excuse to
hit the communications network again and again, without irritating
people immensely (and successfully getting through the
social-media-overload phenomenon).
