Star Wars Day

Myles & I built a Lego Jabba The Hutt palace and lit it up with a torch for some flickering shadows.

Pi2Scart 15khz 240p with a Philips PAL Tv

I have set up Scart out on my Philips 28" TV with Pi2Scart and this is a tricky one to call. The interface worked perfectly, although the Pi can no longer be seated in the Picade enclosure (in fact it will require some work just to get the door to close).

The default parameters worked perfectly;

  hdmi_timings=320 1 16 30 34 240 1 2 3 22 0 0 0 60 0 6400000 1

And I played around with some optimal output resolutions from pi2jamma


but in the end I got best results from letting libretro output the native resolution with some black bars on most games.

The picture is now a lot more stable (you can see some of the flicker in the composite screenshot) and the colours are more vibrant. However games higher than 240p look clipped and the Emulation Station interface is tricky to use at the lower resolution.

The best of both worlds would probably involve having a separate Pi+Pi2Scart for Mame games up to the 1990s. Anything after Neo Geo would probably be better, even with flickery composite.

ReactVR at Dogpatch

I gave a lightning talk at DublinJS yesterday, accompanied by a live ReactVR demo. There were some great talks on VueJs and React, plus some good tech demos - I particularly liked the hacked Daydream controller.

My slides are here and you can clone and run the demo in your browser here.

The tech is already very stable but geometry requires a lot of optimisation and you'll need to use technques like texture baking to get a fast enough experience for users with headsets.

Horror on North Brunswick Street this Saturday!

Come and see some short horror films this weekend - bring a few beers and enjoy a mixture of 8mm and 16mm stories. Both main features are shot in black and white on spring-driven cameras and developed by hand.

All films were shot and developed with the assistance of Dark Room and their amazing 16mm workshop.

The first is 'Electronic Voice Phenomenon' - delving into the clash of religion and science in Ireland, this film hones in on a period of detente in the 1970s when priests and engineers joined forces to record voices of the dead.

The violent, amateur photographic development process adds weight to the spectral presence in this spine-tingling film, as our heroes face down forces of evil and the outcome is uncertain as the malevolent power builds to a crescendo.

The second feature 'The Inheritance' follows the hapless relative of a deceased country landowner who discovers that his estate is not the windfall it appears to be. Featuring Tim Hawkin's inimitable direction, the film uses the results of some interesting research into apotropaic magic to uncanny ends.

I will also be screening an 8mm version of 'The Picture in the House' the infamous HP Lovecraft short story adapted for an Irish location, and perhaps some other spooky films will follow before the night is out.

Bet that trailer audio has already set your teeth on edge!
