SNES <-> Ethernet Adapter + LA Gamespace tracker
Finally finished! I've been working on an example project for the SNES-ethernet adapter. Using it to receive information from Kickstarter to track the progress of the LA Gamespace project! Sorry that it's a bit quiet - I had to turn off the music or I would have went crazy.
Wiznet adapter connected to an ATMEGA644 via SPI. The MCU buffers incoming packet data and converts it to a format the SNES can understand (connected to controller port 2).
Powered from the SNES via 5V - the only other connection is ethernet. Still needs more work but it's getting there!
SNES side written in 65816 assembly - using a super powerpak development cartridge.
(in case you haven't already checked it out - please go to http://www.lagamespace.com/ - the rewards are amazing and there are countless amounts of talented people involved!)

Spent more time than I'd like to admit getting this thing going! Lots of video tricks - the SNES hardware is pretty sweet (HDMA) but mode7 is tough! I have a pretty good development setup now.

Show Me That Finger Waggle
EL wire sign made for George & Jonathan for Blip Festival 2012.
Had an idea to make some kind of LED lit sign for G&J when I found out they were playing. Started toying with the idea of an EL wire sign, then things got out of hand.
Ordered some triacs to switch the power for the animation (first time I've ever switched AC without a relay), ended up picking the wrong part number. Damn. I used a relay module I had on hand due to time constraints but it turned out just fine - not as elegant but I like the clicking. I ended up adding a handheld trigger button so I could waggle manually with the music. Code is simple, when the button is released it shimmies to the left, and when it's held, it moves to the right. Wrote a timeout after 2 seconds to return to a middle position.
Animation driver (microprocessor/relays) powered by a 9V battery through a standard 7805, EL wire powered by two separate 2xAA inverters.
Thank you to:
Kathy who laid out the design / stapled all of the EL wire (perfectly - it looked incredible).
Chris helped me mount everything to a stick so I could hold it way above the crowd without it falling to bits.
A couple of GIFs from WTSNACKS...
Video of it coming out at 5:50- seriously so much fun to walk through the crowd with this thing.
Check out those synced animated LED headbands too - James is a genius.

Lab 2.0
I've been working on a digital vector generator using an AVR and a couple of SPI DACs. Top scope has the values in the time domain, bottom is showing the x-y plot. All shapes are closed for now - now to add a Z / brightness!

Genesis Spectrum Analyzer
Built a custom interface using an ATMEGA328, an MSGEQ7 (7-band spectrum analyzer chip) and a genesis cable plugged into port 2. Sends all 7 bands with an 8-bit resolution with a 4-bit ID to make sure things are always in sync. Running the genesis side ROM on an everdrive.
Really wanted to try my hand at having an audio assisted visual set. Tried an amplitude based one but it wasn't exactly what I was looking for. The chip works really nicely, and once you adjust the threshold it finds the beat very reliably.
Debug / POC ROM - ran a frequency sweep through, works perfectly!
Actual implementation into a new ROM I've been working on. A set of lines are drawn every frame into a tilemap in RAM then DMA'd over right after vsync. Rather than overwriting the tiles under it each line has a defined weight that is added to the array. The sum corresponds to a palette entry, so the longer the effect stays on the more intense the color becomes (black->blue->purple).
Only using the 63hz band here, very effective! You can see around 1:15 where there is a constant tone the effect will play out.
Music by the amazing Danimal Cannon!
Now to (tastefully) work it into some new effects! Should have it in time for Blip Festival Australia.

Blip Australia 2012 Genesis ROM Flyer
After a few months of work it's finally finished...
Code: Batsly Adams
Gfx: Wazpy
Music: Animal Style
Download the ROM here!
http://australia.blipfestival.org/files/BlipAustralia2012.bin
I got to try out a ton of new stuff here, learned a ton in the process.
A few notes:
Wrote a new scene handler, allows separate scenes that can exit gracefully regardless of changes in video modes. Scene timers can be easily adjusted.
New smooth non-blocking palette fading.
VDP DMA routines work perfectly now, most effects are applied to a tilemap in RAM then DMA'd over right after vsync. A 32x32 map finishes in vblank with time to spare, which means no more tearing!
Wrote a utility to split GIFs into frames and convert them into tiles / palettes. Have a special struct for sprites to handle this output for easy manipulation too.
The large comet is 128x128 -> 16 32x32 sprites stitched together!
The green/blue lines in the announcement scene have a (subtle) transparency effect surrounding the black bar. Used the shadow/highlight registers on the VDP here for certain tiles to simulate opacity.
And finally: a full speed plasma effect, which was the holy grail of visual coding for me. Thanks so much to Andy B for help with the optimization.
Can't wait for this!

Card Preview
Circuit card preview in collaboration with Jeremiah Johnson. The result of a few months of circuit design / code.
Release info will be up soon!

Fontana's I/O Sep11
Wrote a new Genesis text scroller that uses the SD-card on the everdrive! The ROM takes any (8x8) bitmap font from a folder and copies it to RAM for scrolling. The string is precompiled, working on an neat interface to edit on the fly at gigs / save previous names to SRAM.
Had so much fun at that show, everyone was amazing.

PCB Design
So I've been on a roll since I've setup new workspace/benches (thanks again Adam / Todd!). I decided to go through my old parts / unfinished projects to tie up some loose ends. Setup a few devboards for a PIC / attiny / propeller. Had nothing in mind, but after some playing around, I had an idea for a project. Contacted Jeremiah Johnson (www.nullsleep.com) to collaborate. The function will remain a secret until gli.tc/h but I can say that it's my favorite project to date, and I'm super proud about how it came out. Got intimate with some (frequency/amplitude/phase) modulation, learned a bunch about surface mount design and SD card interfaces too.
Designed the PCB in Altium, had a few ups and downs. The 3D renders are pretty neat and overall the experience was pleasant. Any hangups were probably due to a misunderstanding how libraries / custom parts are handled.
Ordered 20 boards, they arrived in about 10 days. Doh, botched silkscreen on the front. I think I may have overloaded their silk machine, I'd imagine those halftone dots could cause a problem since each counts as an individual shape. Luckily none of the text was affected and the back is absolutely perfect. They look amazing otherwise, excellent quality.
Fixed it up with my vinyl cutter anyway, it's temporary until rev 2, but that's okay! Looks great.
Works better than expected, can't wait to show it off!

WTPA2 DPCM Drumkit Test
RB drum kit run through a USB-midi converter to the WTPA2.
I fixed a bunch of bugs with the sample code, I had the DAC return to zero immediately after the sample was done playing which caused a nasty click/pop. Now it gracefully levels out any inactive channels.
