Re: Square wave generator - low cost

Hi there, there are tons of websites that claim to know how to build beck machine/s accurately. the one you provided a link for shows individuals commenting on how they have ordered, built to spec a beck machine as per the vid and instructions provided but here is (one of many complaints) a complaint one of them state on the website link you provided here: DO NOT FOLLOW THIS!!!....(i kept this guy's cursing out here)....U WILL FRY UR LM358 CHIPS.

there is one user of this website who gives some helpful info on a "no LED light" issue by stating this: "The design asks for a bi-color LED. You can use Two LEDs in parallel. LED1 cathode to LED2 Anode, LED1 cathode to LED2 Anode."

my worry here with the link you provided which is one of thousands of how to make a beck machine website is how it is not 100% accurate according to the folks who are trying to create beck's machine according to a video provided and instructions on this website.

does anyone have a website they can recommend they have done real research on showing an accurate beck design we can all go by to build a machine hopefully right the first time or maybe not over and over again?

Also an even tougher question.....anyone have a link to a website that shows how to build a beck machine (blood purifier) that has a plug instead of using the old tired method of using batteries? having a beck machine with a plug is ideal for a person like myself who really dislikes having to use batteries repeatedly since i would use the beck machine for myself and others....and that time adds up fast.

thanks,
