Peltiers work on a temperature differential. I think in your application maintaining that differential would be challenging. They are also quite inefficient so generating enough current to drive a DC motor would be stretching things further.

Beats me. Closest I can get is to set the default design rule to 0 edge clearance but this doesn't look like it quite gets there. I assume that panelising the boards you will end up with some tabs somewhere so maybe design the board within a larger carrier PCB and use plated slots where you need the...

I just noticed the "Mounting Hole" layer in this dialog.

But I can't see any way to draw on the layer?

The layer doesn't appear in any of the selection lists I can find.

An actual red LED will have a forward voltage of between 1.9 and 2.2V. Different colour LEDs will have different voltages at their nominated current - depending on their construction and the manufacturer. As a generality: Red, Yellow, Amber, and Yellow-Green are around 2V True Green, Blue, white, an...

On several occasions I have missed a component reference text being in the wrong place - e.g. over the top of the pad for an adjacent part. When the PCB is produced, the reference obviously ends up missing. I was thinking that it would be nice to have a design rule to check for such things. Then I d...

I don't mind being able to push vias around as I am laying traces - but I really don't want to have vias being pushed into SMD pads on the same net. While electrically this is OK, it can potentially create a problem in soldering with solder wicking down the via. A "Via in Pad"-allowed (or ...

Thanks, Tim, I use that all the time. It isn't what I am asking about. "F" only flips the *view* of the PCB. What I am talking about is actually flipping the design: all the components and traces move from the bottom to the top layer and vice versa. This sounds weird but it isn't really - ...

Is there a trick I can use to flip an entire PCB design. On several occasions, I have started a design one way but then it evolves to the point where the "main" side of the PCB is the bottom. I would like to be able to flip the entire design. In practical terms, it might be just a matter o...

Thanks - that helps.

What about the third option (a "dash")?

I am getting some confusing results from this option, so I went looking for documentation and failed to find it.

The option has a check box which has three states: Empty, Ticked, and a dash.

What are the meanings of the options?

In PCB layout, you do have footprints for "LINK20", "LINK30", and "LINK40". These have the same pin number on both ends of the footprint. If you attached one these to a single PIN component in the schematic, you could attach the pin to the nets required and then place o...

I just had some PCBs delivered back from JLCPCB with a USB micro connector footprint. WIN_20191219_13_08_33_Pro.jpg I used a pad stack to define the slot. Start by defining a DIL through hole pad for the copper pad. Dpad1.jpg Create your pad stack, based off the DIL pad. dpad3.jpg It is a bit unfrie...

Ceramic caps don't behave as "ideal" capacitors. Is there a simulation model within Proteus somewhere that can be used to handle this?

I agree that is how it works. I wasn't previously aware of the context menu method.

Just seems more than a little inconsistent.

Intuitively, I would expect both the code editor and the debugger window to share the font attribute.

It is the debugging window - single stepping, etc.
