Pre-stream technical adjustments.
Added 2020-04-25 19:18:32 +0000 UTCThe lighting was way too bright for the stream, so I've fixed that.
As a bonus, the light is going to last a lot longer now the LEDs and driver are running at a third of the original power.

You can, but it's a bit harder if they're covered in the protective goo. You need to preheat the panel,which can be done by powering it for a while to warm it up before turning it off and immediately moving in with your soldering iron to adjust the resistors. If there are two resistors in parallel you can remove one from the circuit just by scraping a channel through its carbon film.

2020-04-28 03:16:09 +0000 UTCDo you think it’s possible to do the same thing on the mains powered cobs? I remember you adding a capacitor to one, I’ll have to watch that one again.

2020-04-27 18:03:40 +0000 UTCCool hack, Clive. Imagine could use a potentiometer sense resistor, to adjust brightness, as well. Or, something a bit more fancy. Use several sense resistors. To make a light bar, dance through different brightnesses. Through traditional electronics or buy a Arduino bored.
2020-04-26 22:47:45 +0000 UTCWell that was three hours of fun. Cheers Clive. One thing that the light did emphasise to me at least, your beard 'sills' are developing nicely - are you going the full ZZ Top? Also, I take it that the extra candle was to help with the exposure levels and you weren't contemplating kicking things off with a hymn?

2020-04-26 12:44:08 +0000 UTC6-7W (of LEDs) is quite a good amount as a fill light (for filming) versus the area illumination strip light it clearly started out being. Ewen

2020-04-26 09:47:45 +0000 UTC1.6 down to 3.6 is 1.2 F stops. Should be fine. I did hear a story about a BBC researcher who tried to use dB-Ohms extensively in a report but tied himself in knots due to the voltage/power issue.

2020-04-25 19:45:56 +0000 UTCAccording to my phone app (Electrodroid), you went from 1.08 ohms to 3.6 ohms. Quite the jump!
