45 Volt Battery Stick
PCB holds five each 9 Volt batteries in a very tight package with snaps that mate to a connector for a "455" battery.
AA to High Brigntenss LED
Thunderbolt GPS Serial Driven Status LEDs
A PIC circuit that fits inside a connector shell and monitors some data packets coming from the Thrunderbolt.
Flashes a LED once per second, Indicated if Locked to GPS, in holdover or recovering modes.
Also indicates major and minor faults.
Could be used for other things that depend on reading RS-232 serial data coming from a DB-9 connector.
5590 Type Plug
Can be made specificlly for:
12 Volt output (shown below)
24 Volt Output
4 Wire Output
LED
AA to USB Power
A version of the
Battery Top Power Supply
that includes an "A" type USP socket, like on a laptop. Although
a rechargable 9 volt battery could be used the performance would be far
better when 6 Ni-MH AA cells are used. Battery holders are
available in a long stick of 2 side by side x 3 long or a brick where
they are all side by side in a 2x3 array.
No. 6 Dry Cell Battery Adapter Not Active - Buy From Dennis
For use in things like
Self Winding Clock Co. 'Western Union"
clocks, antique
electric motors,
telegraph equipment, school electrical hands on learning, etc. This battery is being optimized for low resistance and low cost.
30 Nov 2007 - Next wire up a few of the different battery configurations and run some tests.
The idea is to be able to use the Maha MH-C401FS "AA" battery charger
on other sizes of battery. This charger does an excellent job of
charging.
First Prototype shown 30 Nov 2007 - although the adapter meets the "AA" outline specs there are more constraints imposed by the
C401FS and
C9000 chargers. Need to order more parts and build second prototype.
Ideally this would be done in a lather, but I'm doing it in a
drill press.
High Brightness LED Task Light for 5590 Family of Batteries - Waiting on 5590 Plug Development
The idea is to offer an efficient source of light powered from a 5590 family battery.
The photo shows the LED mounted to a heat sink and with three difrerent beam angle optics.
What needs to be developed is the can to hold and protect the optics
and LED and the switching mode power supply to convert battery power
efficiently into the current to drive the LED.
