    LFO LED indicators

    Im not exactly certain why you are using the whole LDR thing, why can you not use a mosfet with a direct connection? Maybe the more skilled members of the group can answer that.

    High-end drones

    BUILD ONE FROM SCRATCH!...I have about 20 drones at this time, but mostly I concentrate on Tricopters, easy to build, dirt cheap, and even an idiot likle me can fly one.

    LFO LED indicators

    Im not certain exactly what you want, there are a lotta simple circuits using the LM3914/4017 for led control, from music. Here is a really bad example: or schematic: https://www.flickr.com/photos/silverwuff/sets/72157608769206085/

    Ok, im thinking of moving this to another part of the forum, but it has so much info, it may not be possible, so Im going to take this in a different direction. So lets just say that I have a fully working unit...(which I am on the verge of happening!) So taking into consideration the density...

    TAH DAAAAH! Ok, gots my Semi Tester just a few seconds after posting the above, and here are the 2 outcomes for the unknown transistor and diode.. So I dont Know what the hell these units are...but they do seem to be working.

    Yes I am impatiently awaiting the analyzers triumphant arrival. I have wanted one lo these many years, but I really do little to no repair, just diddling around with making overly-simple logic stuff. That specific unit.d/678k2 is the same small plastic case as all the others, but lets see that...

    Ok, the last thing is 1 transistor marked d/678k2...why the hell cant I find this stuff??? When I look this up, I get a Darlington...is this correct??

    Thanks very much ED ...what Im going to do is us a proper semiconductor tester, that will supposedly tell me exactly what Diode it is, and its condition. I ve never had one, so this is a really good time to order one from Amazon. I will get back to you on this as both scenarios make sense , a...

    I ALSO HAVE FOUND ONE MARKED d678K2 i DEFINITELY CANNOT FIND THIS ONE!

    You are correct, the units I have actually have a tiny Hitachi logo imprinted on them. The other 2 I cannot find anything on, the Diode shows up as a huge power diode, which mine isnt, its a black blob unit, the same size as a 2n2004

    Thanks all of you for your help so far. Ok 2 more semiconductosr, and a diode.....and Im outta yer hair for a while 1702n-p749 c1390 and df173 ( weird black glass Diode)

    These transistors needed

    Thank you very much ed...Im just hoping the RF section is ok....I want to play around with that like I want a hole in my head.

    These transistors needed

    I actually think I will buy one, they are cheap as chips

    These transistors needed

    Thank you...more than likely, I wont be blessed with the same pinouts. Im very lucky that the original units actually have the pinout names on the body

    These transistors needed

    I need a quantity of 30 of each of the following transistors: 2sa945- Possibly a 2n2222 could be a replacement 2sd467- Possible replacements You can replace 2SD467 with 2SC1383, 2SC1384, 2SC2235, 2SC2383, 2SC2655, 2SC3228, 2SC3243, 2SC3328, 2SC3940, 2SC3940A, 2SD438, 2SD468, 2SD592, 2SD592A...

    Broke a Custom Hardware's Power Cord/Supply. Help Me Find a Replacement Plea

    What did you break, the supply, or the power connector, as the connector seems to be pretty standard.....15vdc. supply, not so much.
