    Hey guys,

    this is my introduction here on the forums as well as my first question.

    I am a budding programmer who likes to do electronics in my spare time, and I want to make a back-off module for my car's tail lights. Similar to the ambulance's/school-bus' wig-wags that strobe their tail-lights when they press their brakes.

    Circuit here:http://www.sentex.ca/~mec1995/circ/motflash.html

    I also like to pickup my components locally but the local electronics store doesnt have the main semiconductor i need, NTE 4093b [CMOS], instead they have a 4093BT which it calls itself a triggered 4093B but when I look up datasheet's for the 4093B it also sometimes refers to itself as a schimitt triggered semiconductor.

    Is the 4039BT = 4039B ?

    Also, for those of us who do not have the luxury of a local electronics store, or for those obscure parts where you have to resort to an online retailer are there any well liked virtual stores in the community? My local store only had 2 4093B semiconductors and I plan on buying extras in case i fry the first board, and i always tend to do a better job on the second board most of the time anyways.

    Just looking for a little information here on the "T" (trigger) suffix on some semiconductors product labeling.

    The 'T' suffix (in two instances I found) indicates that the part is surface-mount. The 4093 is always a Schmitt trigger type part.

    Arent surface mounted components typically soldered with machines? should i be looking for the 4093B's "Through-hole" predecessor or can I hand solder the SMT 4039B ?

    Depends: the 4093BT has a pin-spacing of .050"- half of the DIP version. If you can find prototyping board with .050" spacing, it's pretty easy

    Recommended online electronics retailers (In the US since you didn't state your location)..
    digikey/mouser/newark/jameco/onlinecomponents

    and adapters like this will really help if you buy the SMT version

    But SMT work can be difficult by hand.. but easily doable for the skilled

    Oh wow, i didnt realize they made a SOIC to DIP adapter. See, im familiar with the definitions of these components i just do not know what they look like in the wild. compounded by the fact that the parts arent labeled as what they are (to the beginner) this "easy fun project" can get kind of big, and hairy.

    Get the 4093BP or MC14093BCP.

    Digikey is very friendly to small orders. For things under 8 oz you can get USPS shipping for $3.22.

    ALWAYS check the data sheet for anything you wish to buy. All the ins and outs of the part number (should) will be explained. Don't order something you don't know about. As always, ask here and we can double check things with you (but it's your money so...).

    Those adapters look nice if you want to go the SMD route (something I actually prefer to do) but don't order them there unless you are in extreme hurry. EBay sells similar items for 1/3rd the price, but since they come from China they take 2-3 weeks to arrive. I stock mine.

    Let's see... if you get into embedded computers don't try to build the first one. BUY it to make sure it works!

    Automotive modifications are not allowed here so if you build that sign don't put it n your car. <g>

    And welcome to the forums!
