Short: Converts 12VDC to 12VAC for ext. modem Author: archy@rhea.otol.fi Uploader: archy rhea otol fi Type: docs/hard Architecture: generic This is information about building a piece of hardware, that converts +12V DC to 12V AC for an external modem and/or supplies a few hundred milliamperes of -8 volts.. those st*nking PeaSea powers are lacking -12V nowadays. Saves a wall outlet, modem turns on the same moment as does the computer. Cool for tower-builders. Circuit consists of a power-IC TDA2030, five transistors and couple dozens of passive components.
