Ping pong ball computer |
Bordtennisballregnemaskin |
|
| I got an idea to try to make a mechanical model (driven
by a ping pong ball) of things going on inside a digital
computer. The result is a model that can add two numbers,
an accumulater as we call it in computer terminology.

Jeg fikk en ide om å prøve å lage en mekanisk
modell (drevet av en bordtennisball) av noe av det som
foregår inne i en datamaskin. Resultatet ble en modell
som kan summere to tall, en akkumulator som vi kaller det
på fagspråket. Flere bilder Hvordan virker den. |
