Circuit Exchange International has been updated on Saturday 11th July 2020.
I am also including the updated pages for June 2020 as well.
The RF MilliVoltmeter Circuit by Rodney Byne has been updated
with New Links. Direct link to this page below:

A new article on Making PCB's has been added to the Practical
Section, but in fact its cheaper to have them made by PCBWay.com

Its over to Belgium now and a new circuit by Tom Borreman has been
added to Control and Interfacing. This is a PIC based infra red remote
control extender, link below:

In the media section I have wrote a review about a TP Link TD-W9970
router. Although aimed at the UK market the small section on avoiding wifi
interference can help anyone using wireless :

In RF circuits there is a multi frequency AM transmitter designed after
a suggestion by one of my viewers:

Back to England now and Eric from Leicester has built and made a
fantastic job of the late Graham Maynards 'ACE' vinyl preamp.
You can see the project at the bottom of the page and also in Audio
Circuits gallery, links follow:

Finally in Switching Circuits, I've included the circuit for a
two channel opto isolated relay module. These are available
worldwide on Ebay and Ali Express:

There have also been some slight cosmetic changes; if you are
viewing in 1920x10800 resolution, then the font size has been increased.
I know this site does not look great on mobile phones as some of the
images are large and the menus small on a phone, but working on this as
well.
New articles next month include Transient Analysis with LTspice,
FET configurations and a high gain audio preamp, and more articles
are being prepared as well.
Thank you for visiting Circuit Exchange International
Kind Regards,
Andy
