Cost estimates on a new ID. Basically I'm giving you numbers based
on top notch ID guys. That is what GTA03 had. Also my past in
overseeing Camera design ( DSC and webcams) and MP3 designs ( less so
here as Creative 'insourced' designs after the first couple of
products.) But as a general rule of thumb I'd expect to get sketches,
renderings, 3D Shells, samples for no less than 100K.. ah
on the schedule... 4-6 months. YMMV. Then you have the ME work
where the plastic meets the sand ( silicon) sometimes its a snap.
other times a PITA. This is a tricky workflow interface. Some ID
guys like to control the ID all the way through the mech.. But
mech must interface with PE.. so you get changes required by
PE that can flowback through Mech to ID.. However you do it
ID, MECH and PE must be tighlty coupled.
Tooling costs: ballpark 150K. But again YMMV. it depends on the
number of tools, how many times you fuck it up. special processes.
And who cuts your steel. I've seen quotes below 50K. I cant
vouch for the finish there. Anyways, the GTA03 ID was pretty
damn good (and I've shipped designs that won effin art awards)
I'm recalling numbers around 250K for the tooling.. could have
been less when all was said and done. so YMMV.

That's really hard to put numbers on. I'll just talk about my days
before OM. and use an example from the camera business.
My first two cameras:
Go click on clients. click on creative labs.)
two cameras. one made it to market the natulus.. the binocular one
The first stage of design.. sketches and renderings is pretty
easy. The next stage was vastly different for both.the final stages
was life for one, death for the other.
The natulus camera was easy from the mech side. EE was off the
shelf. The biggest issue was the flash.. which really ruined the
beauty of the orginal design, but hey it still won an award.
The binocular camera was a mechanical and EE nightmare. I fought
with optical problems, flash problems, sensor problems, battery
The camera was a joy to hold it fit in your hand perfectly
but at the end of the day I couldnt make a final solution.
Today I probably could ( back then we had only low quality
CMOS available to us.. )

YA... time flies, then you die.
