From matt at ucc.asn.au Sat Oct 16 23:42:43 2004 From: matt at ucc.asn.au (Matt Johnston) Date: Wed Oct 27 01:29:18 2004 Subject: [tech] Morwong's power supply went BANG! (bang! bang!) Message-ID: <20041016154243.GB5291@morwong.ucc.gu.uwa.edu.au> As the subject says, at around 8:15 this evening, morwong's power supply went bang. This tripped the circuit breaker for the machineroom circuit, so everything lost power. Having eventually traced the source of the magic smoke to Morwong (it went bang a few more times when re-powered), we replaced the power supply with one of the two lying about from the Prioris. (The prioris is now acting as a semi-external scsi enclosure for morwong, but that's a different story). So morwong and everything now seems happy. A small amount of mail was bounced (about 10 minutes worth) while mooneye was up before morwong had booted, no homedir files should have been lost. The cause could possibly be overheating, as someone said the machineroom was fairly hot yesterday. The aircon didn't seem particularly cold, so I bumped it up a bit for summer.

From what you said, my guess is the bridge rectifier or chopper transistor have shorted. Should not be that difficult to fix/diagnose.

Autofocus was turned off on purpose, the camera has serious issues autofocusing and will commonly end up out of focus. I seem to recall it was turned to focus on about 3 or 4 meters. The green when there is too much light is common for that camera, it is a little dodgy. --d -- Davyd Madeley Systems Engineer, Bridgeway Consulting M: 0422 590 883 F: (08) 9490 1418 http://www.bridgewayconsulting.com.au From davidb-0624 at rcpt.to Wed Oct 20 13:39:16 2004 From: davidb-0624 at rcpt.to (David Basden) Date: Wed Oct 27 01:29:20 2004 Subject: [tech] Webcam #1 In-Reply-To: References: Message-ID: <20041020053916.GJ2100@shikita.rcpt.to> Ummm, have you tried doing a whitebalance?

Autofocus turned off on Davyd's advice.

Yeah, I've set "SPAM" to 5.1 (instant hit, unless there's a negative) and "Probable" to 2.5. If there're too many false positives I'll take a look at it.
