  1. Since there is no way to reply to the original post I started this Thread. My favorite Logic is the Inverter which is not listed in the poll. It is the most useful to me.
  2. Explain more. Are you trying to get Bianary numbers? Are you trying to get Decimal numbers? Are you trying to get Bianary Coded Decimal? A Number Display on a read out? Simple Led output? How many numbers Displayed at the same time? Be more specific.
  3. Maybe if you gave more info on the motor and how it is wired ect it would help us to help you.
  4. Too bad your Email is hidden i could hav emailed you the schematic. Why would someone hide their Email Address?
  5. SVI2004A http://www.diyaudio.com/forums/showthread/t-30842.html SVI2004A = STK4050V http://www.diyaudio.com/forums/showthread/t-28943.htm STK4050V Datasheet http://www.datadart.com/al/sanyo/STK4050V.pdf STK4050V.pdf
  6. There is one good thing about the older computers. They don't get as many viruses and they are less complicated.
  7. I took the words in ( ) and did a web search and all kinds of things poped up Try http://www.google.com
  8. This is a package outline for SOT-23 package http://www.maxim-ic.com/cgi-bin/packages?pkg=6%2FSOT23&Type=Max LF = NPN if my German is correct check here! http://www.fed.de/mailarchive/fed-forum/2002-01/3032.html It is Translated as: Honoured colleagues, I look for the type names and the manufacturer of two bipolar transistors in the SOT-23-Gehaeuse. The construction unit codes read: "MF" on a PNP transistor "LF" on a NPN transistor The Pinning is the equivalent BC848/858. Both transistors are from the same manufacturer, since the construction unit surface and the stempeldruck are perfectly identical. Who can help me here? Thank you in advance for each support. With kind regards Now here is the Datasheet for the transistor he mentioned. http://www.semiconductors.philips.com/acrobat/datasheets/BC846_BC847_BC848_5.pdf BC846_BC847_BC848_5.pdf

  11. It has a 1 1/2 hp Reversable AC Motor. The original Motor burned out so I upgraded to a larger motor that is used on electric gate openers. It Runs on 120vac. It started out looking like this one. I don't have it anymore so I can't show an actual pictures. I had to add a third wheel in the back so it could stand up by it's self.
  12. I found both of those too It just Gets me that I can find All of these Exact Datasheets for Everyone else but, I can't get the exact one for a simple Transistor for myself. Man it buggs me bad!!!
  13. Here is a Diagram of a Remote controlled Lawn Mower that I made some years ago. The Lawnmower was a Push Type with 2 wheels. I modified it with Solenoids that push pads on the wheels for steering it. This was a Wired Remote Lawn Mower and the biggest Problem was not running over the cords.
  14. The easy way is with a switch or a relay. Here is a Diagram.
  15. I started out here and got confused after that. http://www.vmarsmanuals.co.uk/newsletter_articles/62set_converter.htm
  16. I believe the D in the part number stands for Darlington and this does not look like a Darlington replacement.
  17. The circuit takes the Ground and switches it on and off alrernately.
  18. This is a Transistor D2065 [M] printed on it which is Matsushita which is now Panasonic. I figure it is a 2SD2065 NPN Transistor. It is in a Kenwood KAC-624 Carstereo Amplifier. There are 4 of them in the Audio Output Stage of the Amplifier. What is curious about this Amplifier is all output transistors are the same not compliment pairs . The Transistor Gets Hot and shuts down and one or more of these transistors are bad. I need a Datasheet for this so I can see if any of the Transistors I currently have will work in place of this Obsolete Transistor.
  19. Check out this Website for another Idea! http://www.ee.vill.edu/ion/index.html
  20. Here are some links that may help! http://translate.google.com/translate_t http://www.tranexp.com:2000/InterTran%20 http://world.altavista.com http://www.faganfinder.com/translate What Language is it! I think it is Polish
  21. If you look at thr datasheet it tells you what they printed on the surface of the chip.
  22. The Closest i could find is this Datasheet. sn74hc32.pdf
