.. hold it up in the pot. Shove the red led up the tube to the top. Then secure the green led to the base of the tube. (I used wire ties and tape.) Step 6 Make the Flower! I used a silk rose. Luckily, it was made of layers of silk which I could ...
.. but I had a working range of a meter or so, this needs bearing in mind when placing the circuit. Its also a good idea to wire LED1, the coloured LED near to the photodiode, that way, you know that the unit has received a signal. The IR ...
.. for the probe contacts. Gold or silver plated contacts from an old relay may be used, however a cheap alternative is to wire alternate copper strips from a piece of veroboard. These will eventually oxidize over but as very little current ...

.. as well for now. The coils The RM10 core and the two 12 uH coils weren't available either so I had to buy some cobber wire and some ferrite cores and do the coils myself. I got a spool of 0.75 mm insulated cobberwire, a couple ferrite ...
.. sink on triac. The rest of parts are defined in schematic. You must be careful when you connect IrLightDimmer to electrical wire, so you must break fuse switches of your lights. All connections must be like in my schematic, otherwise device ...
