• Previous RT is to remind people that deliberately misleading statements are available in both left and right wing flavours. 18:12:54, 2012-07-28
• I don't understand Critical Mass it must be said. The idea that you want to be treated as "real" road vehicles by breaking the road rules. 18:15:59, 2012-07-28
• I suppose it will do it though, albeit more likely by having bicycles legislated like cars as a result. 18:17:06, 2012-07-28
• Breaking rules leads to stricter enforcement. If they start demanding licence, insurance and so on for bicycles, use will decrease. 18:18:11, 2012-07-28
• Getting more people onto bicycles to increase common awareness of them is what will make them more treated as road vehicles. 18:18:50, 2012-07-28

• Tested the 9 Meanwell PSUs I took from the big pile at the hackspace. 4 very dead (deeper than a blown fuse).. 22:12:23, 2012-07-28
• ..3 of the SP-320-5's power up with fan fine. 1 S-40-12 fine, one SP-300-5 powers up, but no fan. Later is temp-controlled though. 22:14:11, 2012-07-28
• Will need to test for extended periods next, of course. But will need a static 5v load. 22:15:18, 2012-07-28
• Some nice inductors and MOSFETs on the dead PSUs though, so may salvage them if individual components functional. 22:16:58, 2012-07-28
• @Scaley_Jencen Well, enough to make the mounting plate on a 10" bell-jar, so something about 12" square and 5mm thick. in reply to Scaley_Jencen 22:36:04, 2012-07-28

Woke up on time.

Helped mum collect a metal sofa-bed.

Made some fantastic pork crackling.

Got 4th section of the fence up (final one tomorrow).

Got access-ramp frame made.

Got base of vacuum-former base half built (rest tomorrow after glue dries).

Drank a lot of tea. All three meals too.

Bed shortly after cuppa and a quick shower to remove creosote smell and sawdust.

I’m aiming to finally build a wearable, and managed to find a cheap alternative to cutting a set of video glasses in two for a monocular. I got a broken analogue video camera off ebay that had a colour LCD viewfinder. It was a bit of a gamble that being analogue it would have simpler inputs than a digital camcorder, but it paid off. I received the camera today, pulled it apart and got it running on it’s own. 0.2A @5v with composite PAL input.

There’s a 4th pin on the connector though, in addition to Gnd, 5v and video. It’s marked “HD” on the viewfinder PCB, and I traced it back to the IC where (after going through a SMD transistor) connects to the “HD” pin 30 on the controller IC.

The datasheet for the IC expands it a little that the HD pin is for “HD pulse output”, but I can’t find anywhere that explicitly states what the HD pulse is.

I’m *guessing* it’s something to do with the frame timing since the only other HD I can find in the sheet relates to “Horizontal Direction”.

The IC is a Sony CXA1854AR by the by.

The camera supplies the HD pin on the connector with 4.3v however, or at least seems to. I thought I tested it for voltage with the display disconnected, but I’m not sure now. Rather sleep-deprived.

In any case I’m thinking it’s either a case of the IC pin using the transistor to pull the connector pin low, or more likely now that it’s actually a 5v output and my multimeter detected it at only 4.3v due to the duty cycle of the HD pulse. The HD pulse presumably would be something to sync with the video or on-screen text display. But it seems to display PAL video with no problem when it’s not in use, so unsure.

Really I’d just like it if someone can put my mind at ease on the subject. It doesn’t seem essential, but I’d like to know what it’s supposed to do.
