RSVP Collapsible Silicone Funnel
Someone gave us this silicone funnel as a housewarming gift, and I looked cross-eyed at it before shoving it to the back of a drawer. But it turns out that we use it
all the time. It’s been used to funnel olive oil, homemade limoncello, beans, rice,
and filling for a door sock. (It’s also a big hit as a toddler toy.) The funnel is 4" in
diameter and 4" tall when fully expanded, and it does in fact fit in the back of a
drawer when collapsed. That gives it a big advantage over my old plastic funnel
set, which practically needed a drawer to itself. It’s also easy to clean. I’m thinking
of buying a second one (in a fun color) to keep in the car.
Got a project to prototype? The basic
Freescale Tower kit consists of the 32-bit
microcontroller board with USB and RS-
232 interfaces, accelerometer, four display
LEDs, switches, and a potentiometer.
Additional Tower modules are available,
including different microcontrollers, an
LCD graphic display, sensor board, wi-fi
board, and a prototyping board.
The kit’s DVD contains the Code Warrior
IDE and supporting MQX software. It also
includes 4 tutorial labs.
The Tower system is easy to set up and
begin using. After experimenting with the
labs, I was motivated to wire a solderless
breadboard with light and temperature
sensors to the Tower’s side expansion
port, then modify the lab code to read
these sensors remotely via the internet.

M-Audio Fast Track
I can remember a time when recording basic multitrack
audio on a desktop computer was a daunting task and
cost-prohibitive for most. Thankfully those days are behind
us, and songwriters looking to record digitally have a number of affordable USB audio interfaces to choose from.
