Yes, would you believe it but Dallas has obsoleted the digital potentiometer chip that is used in the AtomaHawk kit. They don't have a replacement either. So if you want to get yourself the AtomaHawk then let me know. I will order a limited number of the DS digital chips but when they run out, that will be the end of the AtomaHawk kit. Mike.

That really sucks. What are the specs on that piece? Perhaps it can be sourced from another manufacturer...

What's the digital pot used for? I've never really seen them used as anything other than programmable trimmers. I'm sure there's something else you could use. There are various SPI-controllable VCAs out there. Gordon MM0YEQ

This is the only one that can run a -5V - 0V - +5V rail. DS1666-10+ is it and I can't find any replacement that does the wide voltage range. ________________________________

What does the digital pot actually do in the mod? Gordon MM0YEQ

Hi! Not a pin exchangeable part but should be functional compatible (also +/- 5V range, 128 steps and similar interface) and non volatile as an addon: http://www.intersil.com/products/deviceinfo.asp?pn=ISL95710 unit price 2.12$ (webpage price for calculations) other pots from Intersil: http://www.intersil.com/product_tree/Digital_Potentiometers_%28DCPs%29.asp As little adapter PCB would be possible so that you don't have to make a complete redesign.

But the RS-Components (Austria) webpage tells me that they still have 9 package unit on store (but don't tell you how big one package unit is...). I could order at least 2000 pieces - you get the unit on store amount when trying to order 10000 pieces... http://at.rs-online.com (German) but also on the UK page: http://uk.rs-online.com Article number: 139-420 Ciao Peter The information contained in this e-mail message is privileged and confidential and is for the exclusive use of the addressee.

Well I'm definitely buying one. I've been meaning to since the day it came out but things kept coming up to steer my cash in other directions. But this pressure is exactly what I need to buckle down with some ramen noodles for a week so I can buy the Atomahawk! So please save one for me, I'll be able to make the payment around this time next month or earlier. --- In korgpolyex@yahoogroups.com, Michael Hawkins <korgpolyex800@...> wrote:
