Strongly suspect that they have copied one of the circuits sound.westhost.com/articles/xfmr-dc.htm , almost certainly figure 8 Rod Elliott also says "Commercial use is prohibited without express written authorisation from Rod Elliott". Let's hope that such permission has been sought, if that box uses the design on the webpage (caps 4700uf, diodes 1N5404), or something that could reasonably be construed as similar. I think if you read it that is commercial use of the written material. You can't go and write a book on the subject and sell it and use that article or significant parts of it. I don't believe it is possible to protect the rights to a circuit idea (other than by patent). Especially not one that could be readily designed from scratch by a competent engineer. It's a fairly generic and very simple circuit.... you couldn't prevent copying etc.

It's nothing new and has been around for years in the "public domain"!

Craig In the first place, if you read the copyright notice in that article, it clearly relates to the written word, not the circuit design. The author is not seeking copyright protection for his circuit, but for his prose, probably because he understands its not available for his circuit, both because copyright doesnt apply to circuits, and because as Jez points out - if you want to block DC it is pretty obvious. This was (is) a big issue for the innovators I worked with. Arthur and Owen probably have a dozen patents between them. Andrew almost certainly has too (although possibly owned by Kef TAD and others). You may recall this business of protecting innovation came up in the discussion of the F1 arm. People assume a lot about the law based on whats "right" (in their view). The law is more concerned with certainty than justice You can patent a circuit (well - you can patent what it does and how it does it) if it is sufficiently different. Copyright is for written and recorded material Copyright office fact sheet

Update for Chris (Stratmangler) The hum is the same with or without the connection to the laptop The hum is not present when used with the PA (which has a chassis ground to earth connection) - huge relief, my new guitar doesn't need a warranty return, although I will probably tighten the jack socket when I restring Frankly I wouldnt normally look to record direct from the guitar pickup, but mike with a couple of small condensers, so the lack of ground on the M-audio wouldn't be an issue. The pickup is for (don't laugh) "stage use". But I was checking all the bits worked before I tried to show Harry and his band how to use it to do their dem for the vicars picnic promotion- having not done so in ages, and wanted another input to record The solution is to plug a ground wire into a 13 amp plug, and connect the other end with a croc clip to the spring cable shield on the guitar cable, and provide a route to earth for the hum which the strings and pickup are , erm, picking up. (I still don't really understand how on an acoustic the strings join in - the bridge is bone into wood, unlike an electric metal bridge) As noted previously, my super-conductive body, through slippers and carpet, was providing a route to ground for a current pushed by a tiny signal voltage. Who'd a thought it? All fixed ta

I don't know your name so I'm unable to perform the search. However, I'm sure on that basis I was mistaken in failing to appreciate that the copyright notice you linked to refers to an electronic circuit and not written material. I stand corrected.

From Rod Elliott:
"As noted at the end of every project and article, the information provided is for personal use only. Commercial use is prohibited without express written permission, and depending on the project, a small royalty may be in order"
Which is pretty straightforward. Even though a royalty may or may not be required, written permission in needed.
Craig

DC blocking circuits are not different to design or implement why would you need to actually copy some one Else's work other than the fact you are either no capable of constructing such a device or lazy?
Craig the problem with Patents is enforcing the protection of the original concept, process, construction technique that you or AN Other (Company) has come up with is it not?

Craig the problem with Patents is enforcing the protection of the original concept, process, construction technique that you or AN Other (Company) has come up with is it not? Absolutely - the big difficulty is policing your IP, and then suing for plagiarisation. Even a fairly decent sized company would need to be determined to the point of mortgaging its future to take on a major international company. For example, who would take on Samsung, Apple, Microsoft or Intel? The problem being that a patent has to give a recipe so that someone "skilled in the art" could build one. And if some big and ugly outfit decides to follow that recipe and thumb its nose, what are you then going to do?

Hi Craig Could not agree more, been there, done it unfortunately. Hence why Coke, and Worcestershire Sauce and others have not patented their products. These days I actually take the trouble to remove the part numbers from the components I use along with various other methods of making life very difficult for the far east companies to actually take it apart, always possible BUT they will destroy it in the process. The Chinese companies that many of the UK electronics industries use to manufacturer their designs are 'considered the Intellectual property' of the company producing them, hence the amount of cheap copies springing up world wide. Plus try taking on the Chinese never mind Apple

Plus try taking on the Chinese never mind Apple I go to great lengths to do this with the Arkless 640P phono stage. It adds maybe 1/2 hour or more to building one but as I make so few anyway even diy-ers copying it and then making another one for a friend could make it untenable as a product.

Hello Jez
Not often we agree on things however it's your IP
