Red, sweet strawberries…

…with Swedish sourcream. Delicious!

But all good things must come to an end.

Shitwave synced to LSDj

Another Gameboy genius, NeX is at it again. What he has done is to connect the clock output from LSDj to 74161 and 4024 counters then that is sent through (what I assume is) a slewrate limiter kind of thing to control attack and decay. Then that signal iscontrolling the frequency of a LTC1799 variable oscillator which is contralling the clock frequency of the DMG running Shitwave. (Don’t forget that Shitwave sucks though!)

Notice how there’s an interference pattern with the screen update frequency and the left boy. And that this pattern oscillates at different frequencies as the clock speed is being modulated.

LittleFM on GBC

I finally felt motivated to work a little on LittleFM, and the next feature in the pipeline was (the comparitively small) feature of “real” GBC support, ie support for double speed and colour palettes in LSDj which LittleFM has been lacking so far. (Instead it used the oldschool compatibility mode which didn’t allow LSDj to take advantage of the higher CPU speed found in the GBC)

It works great and flashing takes about half the time when done in double speed mode, however I forgot to clear the secondary GBC bakground map when going from LSDj back into LFM, using the classic sel-start-B-A combo. What this means is that the colour pattern from LSDj will not be erased but remain on the screen. This gave this nice visual bug seen below. As you can see, the pattern resembles LSDj’s screen layout.

LittleFM glitch 2
I’m going to finish one more feature before I release LittleFM 0.4, loading and saving of individual LSDj files, so LFM can truly replace the builtin file manager that comes with LSDj. I have an almost working version of this feature, but it has wrinkles which I want to iron out before releasing it.

The last picture is shitwave which actually looks marvellous with the backgrounds residue. It gives the vibrations more life and you can see what’s actually happenening rather than just vaguely vibrating lines. It may not be apparent on the still image, but it looks nice live.

Sorry for the long wait, but have patience!

ReBub

Mats Andersson, Göteborg and Peter U Larsson

Xero commented my track ‘Belsebub Till Frukost’, saying “there’s no such thing (as too much reverb)”. I did this one to try to prove him wrong, of course failing to do so. Turned out rather droney…

Listen to ReBub on chipmusic.org

Mats Andersson is a lying scientologist

Sparkfun Free Day

Sparkfun Free Day

Sparkfun Free Day

Sparkfun Free Day

For those of you who missed it, yesterday was Sparkfun free day, when Sparkfun would give away $100 to all customers, up to a grand total of $100,000. I didn’t really expect to be one of the winners in the noble battle. As one might imagine the demand for the offer was high, and I expected that the pot would be used up within minutes. The problem however turned out to be quite the opposite. The server was so overloaded that nobody could get through. When submitting a form, the page would load for 5 minutes just to tell me the connection was aborted. I heard a rumour that someone had managed to place the first order order after 30 minutes. So I kept pressing F5 persistently as soon as a page returned an error, and I managed to place my order just in time. At that point things were working relatively well, given the circumstances, (Only had to refresh three times before getting a connection) And as you can see from the remaining time and money counters, $9000 (~90 users) were served over the course of three minutes. I’m guessing people started to give up by then.
My persistence paid off, and unless they mess up the shipping somehow, I’ll soon be the owner of a Spartan 3E FPGA.

Veqtor - Parsuitel Orbitelum

Veqtor - Pawsuitef Oubiteum
Veqtor just released his second full length album, Parsuitel Orbitelum. True to his style, the album is filled with frenzy drill’d breaks, but this time mixed with generative music and modular synthesis. 06-07/96 brings back that jungle flavour from those golden years. AG Racing is a clearly NES inspired tune with the famous NES triangle and NES-ish noise made by his own creation BitFreak. 4_1g.blu is a partially (or fully?) algorithmically generated piece which continues where 3-Aulien Caexf-9 and Snowflakes from Retrospective EP left off.
