this batch suffered from saturation of the lower pastry layer with sugar syrup. it is clear that the syrup has to go evenly into the nut layers but less clear how to make that happen.]]> http://jormungand.net/mt/2007/09/baklava_attempt_1.html http://jormungand.net/mt/2007/09/baklava_attempt_1.html Mon, 17 Sep 2007 01:40:03 -0500 resonance

it is sort of surprising how they can do a whole mythbusters episode about destructive resonance and not mention any q-factor or time constant. in any case i was feeling bored and decided to play with an adxl202 i had lying around. ]]> http://jormungand.net/mt/2007/09/_it_is_sort_of.html http://jormungand.net/mt/2007/09/_it_is_sort_of.html Mon, 17 Sep 2007 01:34:18 -0500 my garden project

so far this consists of a two-gallon bucket of water and plant food with an electronic timer controlled fountain pump to circulate it. so far i only have four flowerpots but if they work well it could fit about twenty. ]]> http://jormungand.net/mt/2007/09/my_garden_project_1.html http://jormungand.net/mt/2007/09/my_garden_project_1.html Mon, 17 Sep 2007 01:27:12 -0500 an exercise in overengineering
When I moved to nyc, my linux mythtv dvr stopped working. In the name of progress -- or more likely, encouraging you to buy their own dvr -- time warner does not provide analog cable. This means your dvr has to actually change the channels on your cable box. So naturally I did what any bitter engineer would do: watched commercials for a year, then hand soldered an infrared widget. It has a 20mhz avr in it and I'd been planning on programming it to be a fully general transceiver, but strangely enough, my motivation disappeared after it became capable of changing channels reliably.]]> http://jormungand.net/mt/2007/06/an_exercise_in_overengineering.html http://jormungand.net/mt/2007/06/an_exercise_in_overengineering.html Mon, 25 Jun 2007 21:35:53 -0500 linux interoperability: verizon broadband access with sierra ac595 based on: http://www.pbandjelly.org/2006/12/sierra-wireless-aircard-595-configuration-sprintpcs/ /etc/ppp/peers/verizon:
