We welcome your feedback regarding the site and its contents on this site or any general suggestions/queries. However, please read the following before contacting us:

  • In case you have built a circuit on this site and you are facing difficulties, you are encouraged to post your problem on the discussion forum. Please do not send any emails/feedback about difficulties with the circuits. Many of these circuits are submitted by visitors like you and we cannot check each and every circuit posted on the site, so its working cannot be guaranteed.
  • Queries regarding free circuit design requests will not be entertained. You can get them professionally designed here.
  • Do not ask for schematics of TVs/ VCRs/ Monitors/Tape recorders and other electronic appliances.
  • We admit there are a few circuits that are not very clear due to the bad quality of the documents that we scanned as a result of which the part numbers may be blurred out. Sorry, we can’t help you any further with those circuits.

PLEASE NOTE THAT ANY MESSAGES CONTRARY TO THE ABOVE GUIDELINES WILL NOT RECEIVE ANY RESPONSE.
