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.

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.

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.

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.

This was much less of an ordeal than I was expecting it to be. With the sierra kernel module loaded, the card shows up as three usb serial ports, and you can connect via ppp through the first one with a pretty simple set of scripts. The only trick is activating the card, which can only be done in windows with the included cdrom. It can also be done with a vmware instance of windows inside linux, which is helpful for a computer with neither windows nor a cdrom drive.

Performance is better than I had expected. SSH sessions are relatively responsive (think dialup-ish) and my highly anecdotal bandwidth test (from brooklyn bridge park, dumbo) is 131 kilobits/sec upstream and 537 kilobits/sec downstream. Verizon has a rather mystifying terms-of-service which implies -- but does not make explicit -- that they intercept and analyze all your packets. Since I have a pretty fast DSL anyway, I vpn proxy pretty much everything through that.
