Hideously flickery (but otherwise nice) LED tape. (Patreon)

I managed to lose the focus in the middle of this video briefly.  I think I might make a target card for the camera to lock onto.

This video is also using my currently poreferred audio arrangement, which still sounds a little boomy, because my voice is quite bassy and the iPad must have been filtering that out a bit.

Comments on the video welcome.

Horribly flickery LED horse-race star strip. (with controller schematic)

The visual appearance of this LED strip is actually very good, with big clusters of bright and colourful LEDs that emulate a strip of coloured lamps. Sadly the control system uses polarity reversal at mains frequency to switch between two channels, so the end result is violent 50/60Hz flicker that is quite annoying to say the least.

Have to say, it is pretty flickery ;)

I'm liking this audio quality.

I don't think a target card should be necessary. In this case you perhaps just didn't give the camera enough time to focus. For me your voice isn't too boomy - but remains a little too quiet and quite sibilant.

I use a D3100 for video and turn autofocus off. Banggood has a very good microphone for under $4. Will that help you? Search microphone and sort by most reviews. I think I have a video posted with them.

I like this new way of doing things, as far as many videos going to patreon first (sneak peak'ish). I don't think it never needs to be a day or more later to show up on youtube. This lil' perk is nice.

I bet the listing title is a clumsy Google translate word association thing. Chasing > Steeplechase > Horse Race

Wow, you were really not joking about the it being hideously flickery. For the last couple of months or so, due to a health issue I have started suffering from hypoxia induced petit mal and some types/frequency/patterns of flickering/flashing lights can trigger it. At the very beginning of this video while the pverall light level was normal, it was just a gentle barely noiceable slow flicker around the edge of the LED clusters on the tape and was no problem. It did get worse when you lifted some of the tape to the camera which caused the overall light level to drop but it was still just about bearable, just getting mildly unpleasant. Fortunately, your title had already given me a heads up so I was ready for the first increase but the much greater increase in flickery would have totally caught me totally unawares if you hadn't warned us that you were turning off the lock. For that was trully hideous and I only just caught myself in time before 'going away' for a little while. Not at all nice. I hate to think how that would have looked like through the Ipad. Your volume might not be perfect on the new setup, but it is more than good enough and unlike the Ipad setup, it doesn't constantly change in level as you or your head changes position. As 48snapper mentioned, the only slight issue is an occasional slight sybilance though the level is generally OK, needing at most a 5% to 10% increase above my normal volume setting.

I think the audio on this one is better than the previous one with the Beacon. Quite acceptable to me

Wow, yeah, that is quite flickery! I'm pretty sure prolonged viewing of this video leads to rental mentardation.

Audio sounds really good. On the flicker/circuit design...what would a "better" (less flickery) circuit look like? Follow up video with hacking potential, perhaps? :-)
