For re-sizing images you could use Irfanview (freeware).
Open the image in irfanview and then press 'CTRL R' and choose a new size.
A good size is 600 wide.
Save it and upload.

Good morning

Open a reply window and look at the 'Attach' entry below the text entry window.
Some restrictions on file type and size are mentioned there as well.

If the size of the attachment is realy large, attachements can be placed in the 'download' section of this forum:
http://www.overunity.com/index.php?action=downloads .
Then click on 'myfiles' (you should be logged into this forum first).
Finally click 'add a download'.

Good afternoon
I have a general question I hope someone can answer...
Is there a simple circuit I can add at the output of the JT that would oscilate the output? if anyone could provide such a schematic that would be fantastic
Thanks
