current version: 0119b
This began as a sort of hardware version of BriadLab but is becoming some kind of cellular moving image organism or distributed display thing. Influenced in some ways by T2Tile but doing different less ambitious things.
Playing with pattern swatches as cells.
[08/02/19] plan for the next week is to work on a font for drawing with. a set of tiles that can connect into different patterns.
[08/02/19] playing around with images, thinking of having little pattern swatches for the screens, will need to make some bitmaps/font. they can then infect each other flipping bits of the weaves in each other?
- [01/02/19] simple version running, 4 possible states, inherit from parents and pass to child. Next try drawing the knot crossings instead of numbers.
- [29/01/19] Aim to get some coding done this weekend 02/02/19.
- [29/01/19] PCB has arrived! assembled 18 tiles
- [26/01/19] PCB arrives on 29/01/19
- using the convenience of arduino, as i can use the arduino as isp to program the attinys
- for drawing to the screen i am using datacute's Tiny4kOLED Library but i might strip it down some more if i end up needing to
- pcb 0119bfront and back back
- attiny84 (0119b using SOIC footprint) - datasheet
- OLED 128x32 I2C - the four pin type you find on ebay
- a bunch of breadboard spaced header pins & sockets
- power from a socket, or can use coin cells, i'm gonna try get it hooked to a solar panel
- i am avoiding making any enclosures at the moment
- attiny84 has 8k of space which should be plently for the first braid animation tests
- 12mm x 40 mm tiles - not sure how deep they are yet till i assemble one, should sit pretty flush but we'll see how they go
- bigger IC ?
- smaller IC !
- bigger/smaller screen ?
- colour ?
- add 20Mhz xtal ?
