Monotype Computer Control: First Run

I have my 12-point Binny Old Style diecase set up, so last Saturday, I tried my first run with my laptop controlling my Monotype Composition Caster. The text is a little note to include when I ship type across the

Video: First run of Monotype Compostion Caster Computer Control

I just posted a video on YouTube of the first run of my Monotype Composition Caster under control of my laptop computer. I have been working on the hardware and software for this interface on and off over several years,

Monotype Computer Control: Diagnosing Air Flow Problems 2

After about a year and a half of ignoring the project, I’m starting again to work on my computer-driven interface for the Monotype Composition Caster. When I left off I was diagnosing problems with the ports having inconsistent air flow

Monotype Computer Control: Diagnosing Air Flow Problems

One observation I have made while testing out my Monotype composition caster computer interface is that not all its ports deliver the same amount of air flow. On some, the air pin in the caster lifts and drops crisply in

Monotype Computer Control: A Long Overdue Update

My last post about this project was over a year ago, wherein I mentioned that I had purchased the aluminum stock to make the main parts of the valve unit. A lot has happened since then, to the point where

It’s Getting Real

I actually went out and purchased some aluminum stock for making the computer control valve for my Monotype. That’s a piece of 1″ aluminum square bar which will make the mouthpiece that fits against the air holes in the caster’s

An Interem Solution to the Pneumatic Valves Problems

This week I’ve been occupied with (finally) putting away all the display mats I bought last year at the Anderson and Skyline matrix auctions. They have been cluttering up the shop since last summer with their variety of packaging. I

More information on Matrix pneumatic valves

This week I was having another look at the pneumatic solenoid valves I want to use to run my Monotype from a computer. I was somewhat disappointed that the valves I had were the Normally Open (N/O) type and designed

Measuring air valve spring strength

In addition to poor flow when open, the other shortcoming of my stock of surplus Matrix pneumatic valves is poor sealing (leakage) when operated in NC mode, where the shutter spring is the only force holding back the flow of

Measuring air valve shutters

Looking deeper into the poor airflow observed on my stock of surplus Matrix pneumatic valves, I did a subjective measurement of the airflow on each port, on a scale from 0 to 5, using a 20PSI supply. At zero, the
