New registrants: if you try to register you will get a message that we are not accepting new members. Due to the limitations of this forum software which is not designed to deal with incessant CIA harrassment, we have no alternative but to disable automatic registration, and then we can't change this automatic message. Your account needs to be created by admin before you can post in the forums. Because otherwise, almost all registrants are CIA sock puppets. To get a forum account you need to send a brief presentation email to loohanforum at gee mail dot com, also suggesting a user name. Then we can enable you manually. But before you even do that, take a look around the forum and my site and decide whether you REALLY WANT to join/post, before you jack us around. Most seemingly genuine people who apply fail to even ever log in once to change their password after we go through the work of creating a membership for them. Then we must quickly delete their account again lest the CIA has intercepted their temporary password. And of the few who do change their password, most still never post. Maybe they realize we are too weird for them, I don't know. They get real quiet, never to be heard from again.

Arduino Uno projects
I haven't done much with my 2 arduino unos since shortly after I got them. Lately I have gotten them back out and have been working on being able to use them to supply squarewave signals like a zapper. Of course it helps to know if you actually have a square wave. Not having a lot of money I looked around to see if there was an alternative and I found one. There is a program that works with the arduino called Processing IDE. It can take the output of an arduino and create the waveform like an oscilloscope. There is also a program for the arduino uno that will drive this program. You can find this information here:
https://www.instructables.com/id/Oscill … rocessing/
There are links to all the files you need plus examples of how to do other things with the oscilloscope. The arduino IDE can run in windows, linux or mac but the oscilloscope program for Processing IDE seems to only be for windows or linux.
So far I have not gotten very far with any squarewave generating except as a fixed frequency and to be honest I have no clue how that program works to determine how to change the frequency. I may just have to break down and build a signal generator that can do multiple types of waveforms. The program I thought was working turned out to NOT be putting out a squarewave, once I got the oscilloscope program running, so I am back to square one on that. But there are other articles on the Internet about this
This is a link to some very interesting stuff on timers and interrupts. The whole site has a lot of good information that I haven't had time to check out. I do know the frequency counters he supplies the code to seem to work quite well.

Anyone with an arduino can jump in here and share links or what you know about programming the arduino uno (or other boards that are relatively compatible). Or even if you do not have an arduino but like the projects and maybe do programming for other boards, jump in and share if you want.

Re: Arduino Uno projects
They sound interesting, though most of my powered pieces have to be outside, and I'm a little wary of having big ol boards out there. Hard to protect.
Seattle's a pretty wet place...
Hopefully the little fellas I ordered are enough for now.

Re: Arduino Uno projects
You have a point, Jeaux. What I am playing with now is the sonar device that came with my arduino kit. I remember someone on here found out that pointing the sonar device at orgone devices causes it to produce orgone and do other things. I went a step further. I recalculated the timings and have the sonar turning on and off at a rate of 33khz. The sonar is pointed at an old combat cone of Loohan's with an 80% duty cycle. I get the feeling the range has been extended about 22%.

Re: Arduino Uno projects
A big OOPS on the frequency driving the ultrasonic device. I hooked up the frequency counter and found out it wasn't anywhere near 33khz and it wasn't very stable, either. Back to the drawing board. Going to cut out all the code about measuring and merely trigger the device on and off. With any luck, this might work. I either need to buy some real test gear or buy a lot more arduinos.

Re: Arduino Uno projects
Some of these zappers actually have a serial input and can be hooked to an Arduino so that the frequency can quickly be changed. Just thought I'd toss that out in case anyone was interested.
