Personally I am:

1. Completing development of a 12 channel sensor network node and sensor board
that runs TinyOS to measure soil moisture, or other analog inputs.  The radios
used are 2.4GHz and can be spaced 100 feet apart in woods or 250 feet apart in open
desert areas and send data to a gateway to the internet at the edge of the field of sensors.

2. Collecting info on parts to build
incubator/PCR/turbidity-meter/centrifuge/minimalist liquid handler as
separate freestanding machines and as combinations in different enclosures,
but with many common parts so the build costs are low.  OSHW licensed TAPR license.
All of these are based on a spindle to hold vials driven by an inexpensive DC motor
with position/speed/acceleration control done by sensing encoder marks on the spindle.
Depends on 3D printing and plastic laser cutting.

3. Doing gEDA and gnucap software development in support of making a small linux board
to do the gateway function of 1. above.

4. Collecting parts data for a solar PV cell power supply for 1. above.

And really these are not 1 2 3 4 in priority, but 4 5 6 7... after immediate income generators.
