Bosch Mass-flow Sensor

I saw an article recently that mentions the HFM5 mass-flow sensor made
by Bosch. I would appreciate any suggestions on how to get more
information or to purchase them in the US. Is there is a Bosch web
page dealing with sensors?

Sealed lead acid battery charger

I need a circuit that will charge a 2.2AH sealed lead acid battery at 25
to 50 degrees C.  The battery is subjected to a discharged of 7A for 5
minutes everyday. I’ve looked at the Unitrode UC3906 and the Benchmarq
2031. They both seem to be suitable. Anybody have experience with these
or other charging ICs? What type or brand of battery is suitable?

Thanks,
Alex

Looking for small 3 digit 7 seg. LEDs

Hello,

I am looking for something I used to use 12+ years ago. They were
three digit 7 segment LEDs similar to those used on the LED calculators
at that time (i.e. TI-55).

The 3 segments share the common segment wires, and have individual
digit (common) lines. I.e., you had to multiplex the digits. They
were not very tall – maybe 1/4" high. Each of the 3 digits had
a ‘bubble’ formed in the glass covering, to act as a sort-of
magnifying glass.

Do these devices exist? I looked at Digi-Key and Mouser, and to
no avail.

Thanks,

        Steven

recommend a snubber diode

I use reverse-biased diodes to reduce power line disturbances caused
by 24vdc electric strikes in my access control system.  These strikes
use about 200 mA.  What kind of diode (I don’t know much about these)
should I be using for longest life?  Should I be use a much higher
voltage/power rating?
