Controlling vintage teletype machines with Raspberry Pi

After being fascinated by teletype machines for many years, Bob Coggeshall has demonstrated a method of controlling a vintage Model 15 teletype with a Raspberry Pi. Doing so is a lot simpler than you would imagine, apart from powering the TTY a simple 24V DC data line is controlled with a relay - which can easily be switched with an N-MOSFET and a GPIO pin.

Futhermore Bob has provied a simple HTML interface that can be accessed from an network-connected device, allowing text entry and controls of the TTY's power and features. It's a great way to understand the very basics of data transmission and also hardware to Raspberry Pi interfaceing.

For all the details including links to the required code, visit Bob's website. And for more, we're on facebookGoogle+, and twitter - so follow us for news and product updates as well.

If you're making a similar project and need to control large currents with digital GPIO - you'll need a MOSFET. We've got you covered with our NDRIVE: N-MOSFET driver/output module:

This high-power N-MOSFET module lets you switch high-current loads using a tiny microcontroller. Perfect for controlling that set of traffic lights mounted in your living room, electric motors via PWM and other automotive projects such as switching high-power 12V lights and high wattage LEDs.
