NP-41 Emulator (may be)

[Chris Chung]

I have 10 units of NP-41 for sale right now. I am asking US$75 for these units and shipping is included. I cannot ship to China and South America as they always failed w/ my non-trackable basic shipping. There is also a simple 3D-printed case comes w/ the units.

A total of 12 units were finished early in the year (between March and May). I kind of lost interest in electronics (this and other projects) and was focusing on other things. I know its been a long time and I hope you are still interested in my infrequent updates.



These are hand soldered and I had also a few failed units that was abandoned. A disc buzzer is included that makes a very little noise, only BEEP works in this version.

With a USB-TTL serial cable (you can get from ebay) you can download 4 application ROMs. And you can also upgrade firmware when it become available. However these features were not extensively tested and definitely on on all the units so consider them beta features.

Another option to update firmware in the future is through the use of Texas Instruments various programmers or "LaunchPad" development kits (about $12.00 + $6.99 worldwide shipping)

I am selling 10 units and reserve 2 units as spares for this lot. Since they are not professional quality, if your unit failed within one year, I will replaced them w/o cost (you paid for shipping of return, I will ship replacement / repair for free).

The units are turned upside down in their simple 3D-printed cases to protect the LCD. They will be shipped in 7 x 4 x 1.5" boxes w/ bubble wraps. There is a printed simple instruction included, like the NP25. There will be no CR2032 included as lithium batteries are not allowed for mailing.



I have this list of members that had indicated interests very early so if there are more demands than 10 they will have priority.
