    Converting LED output units

    Or tape a little calculator to the top of the box and put 3.048 in the memory. ;)

    Converting LED output units

    Be interesting to see the inside of the box. I'm assuming that the power for the IR (?) LEDs in the base plate comes down the standoffs.

    Converting LED output units

    Probably not doable without major physical modifications...but: Reduce the distance between the LED emitter and detector pairs by a factor of 0.3048.

    Sauna Steam Generator - Bypass ne555 timer?

    What happens if you shut the power switch off at at 59 minutes or 61 minutes and then turn it back on? Does it just restart the 60 minute cycle?

    Rain gauge resetter

    And all this was to not loose the total rain amount when changing the display's batteries. ;) Great learning experience. Amazing what these little micro-controllers can do.Good work Ed!:) Ken

    Illuminated Sign

    Probable a 5V, regulated, SMPS (switch mode sower supply), wall transformer would work. Can you measure the current draw with the batteries?

    Questions conserve game console

    Depends on the batteries. Carbon, alkaline, and NiCad batteries will leak over time and corrode the contacts and maybe even the PCBs. Not sure about the varieties of lithium batteries. Put the device in a two layers of ZipLock bags with silica gel packets. Leave the batteries out, or put it...

    Rain gauge resetter

    If you now want a preset for the pulses you might want to invest your effort in learning and construction of a devise based on the Arduino micro-controller. Tons of information out there on programing functions like interfacing displays, keypads, and relays. If you are looking for a challenge...

    Rain gauge resetter

    How is your electronics? Simple, a SPST push button switch wired in parallel to the reed relay. Or to automate, SPST relay contacts wired in parallel to the reed relay, with a pulser circuit driving the relay.

    Rain gauge resetter

    From the Wizard of OZ: "Begin at the beginning!" :) On the attached copy of one photo I indicated a reed switch with a big red arrow. On another of the tilt bucket I point to a magnet with a big red arrow. Every time the bucket tilts, the magnet passes the reed switch, causing it to momentarily...

    Could also modulate the RF burst with a single audio frequency, and demodulate at the receiver. I've done that. But that seems too primitive with today's technology. ;)

    Are you willing to crack open the tilt bucked remote to link in a pulse generator to meet your simulator?
