Date: Thu, 15 Jul 1999 17:51:19 +0200 Organization: Berit s. r. o. X-Mailer: Microsoft Internet E-mail/MAPI - 8.0.0.4211 Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Hi all. I'm completly new to BSD and pure English writing, so be patient:) I've an idea of ``controlling" (read rotating:-) knob (with thermostat) on my room radiator, which has been heated centrally. To keep things as simple (and cheap:-) as possible, I suppose to operate the knob using an DC motor (rotation in both directions) switched by an optron(s) and a rellay(s). And scan the actual rotation through another optron in a similar way how are these things done in a mouse. And finally to modify a serial mouse driver for this ``device". Does it sound clever or stupid? Have ever someone done something similar? Your questions, answers, opinions and advices are welcomed! Many thanks in advance.
