Here are links to NFARL kits:

 

Joule Thief This kit was sold to fund our 2009 Library project.

It is a great kit to use in learning basic soldering, circuit fundamentals, and Manhattan construction techniques.

Power Gate The Power Gate allows you to run your station with fulltime, instantaneous power backup.  A pair of Schottky diodes operate as an electronic gate to connect either of two power supplies to your rig.  Usually one supply will be your normal AC connected station power supply and the other a backup battery.  Switching is completely automatic in both directions; the source with the highest DC voltage will be connected automatically to your rig.

All kits have been sold.

Retro Radio This radio is a direct conversion receiver for the US AM band.  The transmitted bandwidth is limited to the usual amplitude modulation at 4.5 kHz on medium wave and therefore achieves no FM quality.  But it has, especially in the evening and at night, a much greater range and can receive stations from all over America.

All kits have been sold.
