Generate the Atari Rainbow Effect

One of the amazing things about the 8-bit Atari computers was how they could rewrite their display list on the fly, changing video modes every scan line. My favorite application of this was the rainbow effect. I've always wanted to know how to do this, and some searching led me to Alan Watson's example in Compute!'s Second Book of Atari. I trimmed it down a bit to come up with this BASIC code, which you can run on a real Atari computer or in your favorite emulator:

110 FOR I=0 TO 17

120 READ B

130 POKE 1536+I,B

140 NEXT I

200 POKE 512,0:POKE 513,6

210 GRAPHICS 8

220 START=PEEK(560)+256*PEEK(561)

300 POKE START+3,78

310 FOR I=34 TO 98:POKE START+I,14+128:NEXT I

320 POKE START+99,78+128

330 FOR I=102 TO 164:POKE START+I,14+128:NEXT I

400 POKE 54286,192

410 DATA 72,173,198,2,24,105,2,141

420 DATA 10,212,141,198,2,141,26

430 DATA 208,104,64

72         PHA       ; Push A(ccumulator)

173,198,2  LDA 710   ; Load A with playfield 2 color luminance

24         CLC       ; Clear carry

105, 2     ADC #2    ; Add 2

141,10,212 STA WSYNC ; Wait for horizontal sync

141,198,2  STA 710   ; Playfield 2 color luminance

141,26,208 STA $D01A ; Background color register

104        PLA       ; Restore A

64         RTI       ; Return from interrupt

Cigar Box Camera

Paul Beard's made up a cool cigar box pinhole camera.

A brief overview of the cigar box pinhole camera I built yesterday and today.

Built around a 4x5 film holder. Focal length of about 30mm, pinhole of indeterminate size, f/stop 100-150, I think. So reasonably fast -- 1-2 second exposures in Sunny 16 conditions.

Lessons from Mk I that I tried to incorporate:
* use a smaller box so you can more easily remove the dark slides without muffing the shot
* tripod sockets are a good thing
* a shutter is also a good thing: using the dark slide a shutter not always effective. - Link

Ultraviolet Photography

For years I've wanted to mess around with UV photography. Unfortunately, all the websites on DIY UV seem to assume an infinite amount of money and access to specialized equipment on my part. There are two things that I don't like, when someone tells me I HAVE to spend a lot of money (quartz lenses starting at $3000) or that i need specialized equipment (Wratten 18A filters, not cheap either). So I set out to do it my way, and here's my $5 solution to UV wavelength photography. - Link

Hmm, how big a chunk can i get out of a lightbulb so I can make a filter for my srl lenses!

Fake Bluetooth Phone

Stephen needed a bluetooth case mod to functionally hide his snazzy phone!

When i got my $1000/€900 I-mate JasJar last week I certainly wanted to do anything possible to stop it being stolen, So I came up with the idea of having a phone shell that has a bluetooth headset mounted inside so it doesn't appear that i have a JasJar, but instead a cheap old phone, in my case a Nokia 3330. - Link

Sputnik tags @ the ccc

The 23rd Chaos Communication Congress (23C3) is a four-day conference, lots of tech and hackery, check out the badges attendees are wearing--

"CCC-Sputnik is the first public appearance of the Open Source Project OpenBeacon.org and every attendant of the 23C3 is warmly invited to take part in this realtime in-building location tracking system. The CCC-Sputnik project intends to demonstrate the actual possibilities and threats of tracking and data mining with the RFID technology.

HOW TO - Make customizable fleece hats

Ryzellon writes -

"You want to keep your noggin toasty in the nasty winter weather.
You don't want to wear a hat that looks like everyone else's hat.
You like lions (or dragons).

Now you can combine all of these desires into a simple, yet useful, item of clothing that's infintely customizable and tailorable to your (or a recipient's) tastes." - Link.

New shield connects Phidgets sensors to Arduino board

Bjoern writes -

"I just received my first Arduino Shield PCB design in the mail from Advanced Circuits. We have lots of Phidgets sensors lying around in the lab; they may be a bit pricey, but their plug-and-play model is sure handy when you're in a hurry. This PCB makes it easy to connect these sensors to the Arduino platform. The board has six Phidgets (aka 3 pin Molex C-GRID) connectors which are routed directly to the Arduino's A2D ports. It also breaks out 8 bits of digital IO to .1" headers and provides the all-important reset switch and status LED." Thanks Kevin! - Link.
