    I went to my Profile to try to set the clock here but couldn't find the clock. I found where it said my gender is Female! Ha,ha, ho, ho, haw, haw. I changed it to male. How do I set the clock here? How do I set a photo for my avatar?

    "L6" - what kind of transistor?

    The circuit you found works with any little NPN transistor including a 2SC1623, it is not a Jfet. It has a low input impedance which loads down the signal level from the high output impedance of a piezo mic and the transistor has low voltage gain so if you speak loudly you will make an output.

    "L6" - what kind of transistor?

    The circuit you found will not work with a Jfet but will work with an NPN transistor and a low impedance signal source (not a piezo). A piezo throat mic is a contact mic. Go to http://makezine.com/2011/12/20/collins-lab-diy-contact-mic/ to see the different circuit used for a Jfet preamp for a...

    I followed instructions in Google how to clear the browser cache and clear temp files. I rebooted. I needed to log in here but I still do not see a box to allow me to make an attachment. Hero and you use an older Windows 7 operating system. I use newer Wndows 8.1 Pro.

    "L6" - what kind of transistor?

    You forgot to tell us what the pickup is used for. A guitar? A piano? A drum? The horrible circuit will work with an N-channel Jfet or NPN transistor if the piezo pickup is in a drum.  The circuit will not be a linear amplifier with a high input impedance if a Jfet is used. The circuit is...

    I still do not see a box at the lower left corner that will allow me to make an attachment. The area where it might be located is shaded a little with the "Insert Other Media" box on the lower right side.

    I do not need to use an image hosting service (that loses an image after a while) on any other website I post attachments on so why do it here? The new software here should be fixed so that Windows 8.1 with internet Explorer 11 works with it.

    I was going to post the photo of a timer circle (?) that appears for a moment on the left side after I press "make a reply" but before it shows "insert other media" on the right side. But I still cannot attach anything.

    Let me see what happens when I post an attachment from my hard drive: No. There still is no box for me to click on, allowing an attachment from my hard drive.

    What are these pieces?

    I have an ultrasonic dog whistle that looks like that. It is threaded so its length (and therefore its frequency) is adjustable.

    What's happened to all the posts since 24 February?

    I do not see the paper clip nor the "drag files...", nor the link "Choose files". That part of the screen is blank with the "insert other media" box  on the right side.

    Hero, which operating system do you have? Is it newer than Windows 7?

    Your Windows 7 is much older than my Windows 8.1 Pro. Can you try Windows 8.1 Pro like millions of other people have? I do not see "Saving..." anymore when I submit a reply.  The properties of your attachment show that it is a URL, not an attachment from your hard drive. I need to make...

    I have always used Microsoft Internet Explorer with no problems until this website got new software. I think Admin should download Internet Explorer to see what causes the problem, not me trying another browser (which one, Firefox, Chrome or another?)..

    Sorry, I will not use a different browser and I will not change anything because every other website forum works perfectly except this one with its new software. Another problem is when I finish typing and push "Submit Reply" it says "Saving..." forever and I think it did not work. It should...

    About file uploading

    I am making this new post to see if there is a box that says, "Drag files here to attach, or choose files" but the box is missing. Instead there is a box on the right side that says, "Insert other media" as I described before. I use Microsoft Windows 8.1 and Internet Explorer 11.

    It looks like the new software for this site does not allow an attachment to be made so we will never see the schematic. There is a button here that says, "Insert other media" that might allow an attachment. I am attaching a box that says "TEST". No, it allows only attachments that were made...

    Testing to see if an attachment can be done (drag....?). NOPE!

    What's happened to all the posts since 24 February?

    I saw that this site disappeared for most of yesterday then today it is completely new. I also noticed that 5 months of forums threads are gone.
