    Can you please check now and report back? We have done some updates on the community software.
  2. Weird login issue

    Thanks for reporting this issue. I will check and get back to you.
  3. This topic is to clarify the specs of T1 transformer used in T1 is a Standard EMI/RFI Transformer for electromagnetic noise, any 15/16mm transformer with 1mH inductance will work. This transformer is used to reduce EMI/RFI noise and doesn't provide isolation from mains voltage. I am attaching here the datasheet of the transformer. pmcu.pdf
  4. Introduction

    Hi and welcome to our community! Feel free to start a new topic about your project/question etc
  5. A modern day 0 - 30V, 0 - 3A Linear Power Supply?

    You may check this blog for a revised version of the popular 0-30V PSU:
  6. Capacitors?

    These also seems like capacitors to me. I also found a chart that looks pretty close to their marking.
  7. LM2596 overheated NEED SOME HELP

    The diode is needed for the circuit to work, otherwise you may damage the IC or your load. Without this diode the switching of LM2596 can't occur. You may use IN5822 schottky diode or another 3A schottky diode.
  8. Hi Johnpham, I would propose you this circuit published on Silicon Magazine (July 2009). This lead acid desulfator circuit supports 6V,12V and 24V lead acid batteries using a selection switch and it's based on popular 555 timer IC. Most of the pars are easily available and you will need to wind some air coils.
  9. Submit Projects, Articles

    Hi Maleetronic, Thanks for your interest publishing a project on elab! I personally handle the project submissions and manually adding them to our repository after reviewing. So if you would like to submit your project the best way is to send me an email to webmaster @ or let me know here. After project submission i will handle the rest. Let me know, how i can help you further.

    Thanks for posting in this circuit. Do you have a description also?
  11. Electronic Component Organizer App

    The author's website seems down at this moment. I am attaching WinHeist on this post or you can download it from here:

  14. Hot Wire Anemometer

    I have found a simple circuit diagram about hot wire anemometer. May be a good point to start. Look at the bottom of this page: Also check this slides about the theory behind it: Anemometry.pdf
  15. According to datasheet MC14046B is compatible with CD4046B and they don't mention about CD4046A
