He transforms an inexpensive toaster over into a vital tool for electronics engineers and tinkerers.

The only thing I would point out is the diagram you used to show the operation of the thermistor, should have shown it being driven from either a constant current source or as a potential divider with a resistor in series with the Vcc supply . The circuit was driven directly from a voltage supply so the output point you indicated would not vary. I know I am teaching you to suck eggs, so just pointing out to clarify to beginners <span>[View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-b4e1f89e-44d2-474e-9d84-d37582f1f407/contentimage_5F00_1.png:16:16]</span></p><p>&nbsp;</p><p>Regards</p><img src="https://community.element14.com/aggbug?PostID=17093&AppID=70&AppType=Weblog&ContentType=0" width="1" height="1">
