I don't have ready access to the likes of a lathe or huge die for threading the shaft. For example, with my 'Grosvenor' I had the disc mounting bosses turned by someone else.

Steve Anderson wrote:I agree with your 240kHz bandwidth requirement calculation for this, thus if using a similar PWM system you'll be looking at switching in the low MHz region. This may become 'Not so easy', but let me dwell on it for a day or two...

Steve Anderson wrote:In thinking about this, what's going to be the source of video? Does (for example) the 'Aurora' standards converter provide this? And do you have one? Or do you have something else in mind?
Steve Anderson wrote:This definitely does interest me (and Jeremy Jago via previous e-mails) though I will admit I'd take the easy cop-out and use a CRT...of course monochrome in my case, but if there's a requirement for a signal source at these standards, then I'm interested...

it has 16 Club Standard test patterns encoded within it, in fact 32, 16 being linear and 16 being Gamma-encoded. Once I'm finished with the last of the software it's done...a few more hours of work....there's more to it, but my reason for mentioning it here is if there's no source for your 120/25p video I'm willing to uprate it to suit....colour might be interesting (read a challenge) though...

Steve Anderson wrote:Let's start with the light emitters, presumably Luxeons? Have you made a choice as yet? If you have then please pass on their Farnell/RS (whoevers) stock No. so I can download the datasheet(s)...
Steve Anderson wrote:Furthermore, have you made any choice as to how many of each colour (I presume RGB) and in what arrangement you might connect them, series, parallel or a combination of both?
Steve Anderson wrote:The mini-NBTG above could be adapted to produce RGB in the standard you require, but as it's only a 14-pin package (deliberately chosen) the range of colours would be limited. Remember Windoze 3.1 in 16 colours? Eeek...
