Hi, my name is Jarek Lupinski, and this is my site! Welcome! Check out some of my projects, take a look at my resume, and get in touch with me!
Welcome to the Chip Maestro Temporary landing page! While I construct
the new chipmaestro.com, this page will serve as the repository of the
source code, schematics, and manual/FAQ for the Chip Maestro.
The Chip Maestro was a spinoff from my TSUNDERE project, which can be
. After spending a year
prototyping it and two years working on a fully developed mondel funded
by Kickstarter, I shipped the first batch out to Kickstarter backers and
am continuing to create batches for sale.
Currently I plan on selling the rest of the two batches I ordered to
fulfill the Kickstarter pledge requirements, in addition to a smaller
batch to sell to pre-orders and have a stock on hand for backup. In the
future, I will sell Chip Maestros through a third-party. If you would
like to be informed when the Chip Maestro goes on sale, please send an
email to firstname.lastname@example.org
will reply when it's
The Chip Maestro is powered by an Atmega168 chip, supported by a

Before performing any troubleshooting steps, please make sure that your
NES plays official NES games by trying a few games out.
Every Chip Maestro has a diagnostic LED built into it:
your NES, you should be able to see an LED inside the Chip Maestro
blinking when you turn it on, and when you play notes on your MIDI
device. If the light ever stays on for a long time, this indicates a
between the Chip Maestro and the NES. Please make sure your NES
cartridge contacts are clean and free of any dust or debris. It may be
necessary to install a new 72 pin connector if you are experiencing
communication related issues.
If your Chip Maestro is blinking rapidly when you turn the NES on and
are trying to play it, but there is no sound coming out, it may be
necessary to perform a Factory Reset by playing MIDI note 10, A#-1. Your
Chip Maestro may make some sounds at this point. In either case, wait
two seconds, turn the NES off, wait another two seconds, and turn the
NES back on. The Chip Maestro will now have reverted to it's default
The settings on your Chip Maestro are preserved in EEPROM, which means
that they carry over from one session to the next. A full list of
settings can be found in the manual (currently in the tech docs).
