Studied Electrical Engineering at Twente University.

Main interests:

• reverse-engineering things (USB stuff, mp3 players), working on http://rockbox.org
• studying bats and making electronics for recording/listening to bat sounds
• software-defined radio

New project ideas:

• Use two old satellite dishes to allow speech to be transferred over some distance
  • Figure out focal point
  • Create some kind of dish mount
• Create a RFM69HW TNC, based on code by flok
  • Remove 'flok' framing, make it comply with KISS protocol
  • Use 'infinite' package length mode to send typical TCP/IP frames (1500 bytes)
• Create a 'HabAlert' android app, see HabAlertApp
• add opus audio codec support to squeezeboxserver and/or squeezelite
  • an opus web radio stream already seems to be redirected to the client, but squeezelite crashes on it
• create code for remote control of my ZwaaiLicht
  • implement wireless protocol for the NOMZ message ("\x4NOMZ") on address 0x66996699L (no ack)
  • possibly implement a more capable protocol on a different pipe (with ack, learn about extra pipes on NRF24L01+)
  • possibly split control of the light and the motor
• create a FrontDoorDisplay
  • clearly indicates the RevSpace door bell
  • show short scrolling text messages, e.g. to food delivery people
  • remote control over NRF24, e.g. enable/display the display of messages, set the text to be displayed

Laser cutting: I would like to get more creative with the laser cutter, starting with cutting existing designs, for example:

• this trebuchet
• this catapult or the mini catapult
• a cool looking box with gears
