Terms of Use.

Prior to interfacing with the Circuit Essentials platform, users must acknowledge and execute this protocol. Continued utilization of our digital schematics, components, or tutorials implies full compilation and execution of these terms.

If you lack the necessary permissions or disagree with the core logic defined herein, you must immediately terminate your session and disconnect from our servers.

The text, schematics, and code published on Circuit Essentials are copyrighted by Joe Lundgren. You are welcome to:

• Read, quote, and link to tutorials with attribution and a link back to the source.
• Build the circuits described, modify them, and incorporate the techniques into your own work — that is the entire point of publishing them.
• Use short code snippets in your own projects without further permission. Larger excerpts, please ask.

Republishing tutorials in full on another site, or reselling the kits, requires written permission. The Circuit Essentials name, logo, and visual identity are not licensed for reuse.

Don't scrape the site with abusive request rates, don't attempt to overload the host, don't probe for vulnerabilities without coordinating first. Reasonable automated access (RSS readers, search-engine crawlers, ordinary archival tools) is welcome.

The information published on Circuit Essentials is provided "as is", without warranty of any kind. Working with electronics involves real-world risk: voltages, heat, batteries, mains power. Circuit Essentials and Joe Lundgren hold no liability for blown components, damaged equipment, injury, or any other loss resulting from your use of the information on this site.

Always verify voltage tolerances, double-check polarity, and follow safe-work practices before powering anything you build. If you are not sure, ask a qualified engineer.

Design-services engagements are governed by their own written contract, not by these terms.

These terms are governed by the laws of the State of Texas, USA, without regard to its conflict-of-laws principles. Any dispute arising out of or related to this site shall be brought in the state or federal courts located in Collin County, Texas.

If any provision of these terms is held unenforceable, the remaining provisions remain in effect. Circuit Essentials may update these terms at any time; material changes will be noted at the top of this page at least 14 days before they take effect. Questions go through the contact form.
