I used a Hi-MD to trawl for the Robin\u2019s first song of the year. Set it off at 9pm, recording from the mic. Trouble is that it split the file into one group with a bazillion tracks – about 1500. Must have tripped a new track each time the audio dipped below the meter indication and came back. This isn\u2019t useful. There must be a way to can that other than editing all the marks out. I\u2019d really like to not do that again.<\/p>\n

Set me thinking to how to record the Wolves Wood sounds later in the year. What\u2019s needed is a remote timed start. Could set all the controls to manually record and pause, then hit the go button on the remote using a timer\/alarm clock module etc. Let\u2019s see what\u2019s inside the remote.<\/p>\n

The worst part is the plug, which is not only Sony proprietary and nonstandard. The pitch of the pins isn\u2019t on a 0.1\u201d grid.<\/p>\n

That\u2019s just what you don\u2019t need. Having said that, a stick remote sucks without display, and LCD remotes are on Ebay for about \u00a323. So I could stump up for a remote upgrade and get this one to donate it\u2019s plug to the cause.<\/p>\n

Other than that this is a pretty straightforward resistive ladder job – the play\/pause button is a 330 ohm resistor across two of the pins. The resistor values used in Sony Minidisc remotesare documented here<\/a>What I need now is an alarm clock module but Maplin doesn\u2019t seem to do them anymore. Which could be loads of pain using a PIC. Or maybe a 4017 clocked in with a 4060 set to output one hour intervals. On second thoughts the James-Bond-esqueness of the PIC and LED display might be too much to resist \ud83d\ude42<\/p>\n","protected":false},"excerpt":{"rendered":"
