- Headphone modification: I have successfully modified the Beyerdynamic DT 770 PRO and the ATH-M50x for balanced operation with the Pono. This involves the opening of the headphone, drilling a larger hole into the cup and inserting a mini XLR jack into the cup. The original cable will be provided with a mini XLR plug to operate with standard equipment. A new cable with Pono connectors will be provided for balanced mode operation, see cable. These measures will void the guarantee. For other headphones, send me the specifications.
- Internet services: setup and maintenance of web sites (wordpress), database setup (mysql), email service (postfix/dovecot).
- Software: C/C++ and Python programming, microcontroller programming
Tell me your needs. I will try to make an offer.
