todo / ideas

enhance old big clock

• ☑ use MAX3232CPE for +12V/-12V pulse
• ☑ use atmega8
• ☐ use DCF77 for current clock
• ☐ attach 60 LEDs on the outside and display current seconds
  • ☑ use shift registers 74HC595
• ☑ design schematic
• ☐ design pcb
• ☐ drill pcb

lectures/talks

• ☐ google protocol buffers
• ☐ Spaceportal implementation (w/ ptflea/bobapple)
• ☐ 3d printer talk at garage-lab and dingfabrik

Cleanup Alarm

• ☐ start cleanup alarm on a random basis, min 5 days, max 7 days. Fire alarm if 30% different members are present
• ☐ pause raspberryPI movie playback
• ☐ send message "Cleanup!" (or sth. like this) to raspberry PI (on screen message)
• ☐ display message on ledboard
• ☐ maybe throttle internet connection
• ☐ blink exit-sign
• ☐ switch on beacon-lights
• ☐ stop mpd and play alarm sound

funkstrom v2

• ☑ tests with arduino uno
• ☑ python class for serial communcation to atmega
• ☑ 3d printed enclosure (made by xoquox
• ☐ REST-API and Webinterface
• ☐ deploy

warpcore v2

• ☑ order parts for dmx2rgb board
• ☑ rewire leds to control every led
• ☑ animation example in production
• ☑ clean wiring
• ☑ documentation
• ☐ python script for snmp and ledcontrol

powercontrol

• ☑ buy hardware (finger relais, processor, udn)
• ☑ create schematic
• ☑ produce pcb (cnc - thx ptflea/krisha)
• ☑ write atmel software
• ☐ create python REST-Api

heating control

• Step 1 - Enhance current heating controller
  • ☑ attach relais to RF-contact for existing heating control
  • ☑ set relais to ON if space is closed (heating control is now in energy-safe mode)
  • ☑ set relais to OFF if space is opened (heating control is now in normal mode)
• Step 2 - Preparing Hardware
  • ☑ order rondostat hr20
  • ☑ flash openhr20
  • ☐ add software 1-wire slave communication (Benutzer:Xoquox)
  • ☑ use raspberry pi as 1-wire master
  • ☑ design One-Wire Taps (PCB)
  • ☑ order taps (oshpark.com)
  • ☑ solder taps and test with ds18s20
  • ☐ deploy taps + wiring
• Step 3 - Data collection #1
  • ☐ Add temperature sensors to every room (DS1820)
• Step 4 - Data collection #2
  • ☐ Add reed contacts to every window
• Step 5 - Automation
  • ☐ if window opened in $room, close all thermostats
  • ☐ webinterface for room temperature control and stuff

misc

• write new food/drink system with python-blessings + barcode scanner (pacebook tablet)
• 8x8x8 LED Cube in Blue
