Bit of a long-shot here, but does anyone have access to the "Electronic Design" magazine (the one Bob Pease used to have a column in) archive?
I'm looking for a series of designs for solid-state anemometers submitted by a reader.
All I can remember about the articles is that the writer was a US academic, and the designs typically used four transistors arranged on a flat plate at the apexes of a triangle, with one in the centre as a reference.
The designs would have been submitted no later than 2002, but more likely in the late 1990s. (someone at a company I left in 2002 had a subscription, and I used to flick through them over lunch) - I know there is an online archive, but I don't know how good the search tools are, or how well-indexed it is.
Fingers crossed, thanks for reading.
I loved to read his column each month!
Searched Bob Pease on it and got his lab notes;
Just got back to this one, and realised that the schematics in the article appear to be 1x1 pixel GIFs
I searched for the title of that article, and found it had been published elsewhere, e.g. https://pe2bz.philpem.me.uk/Detect-Sense/-%20Air-Gas/T-101-DiffHeat-senceAirFlow/DisplayDocument.pdf
Here is Figure 1 from the above; see references below to earlier articles.
The circuit in Figure 1 combines
ideas from two earlier IFDs (“Low-
Power Thermal Airspeed Sensor,”
ELECTRONIC DESIGN, May 25, 1998, p. 116;
and “Low-Power Solid-State Airflow Detector,”
ELECTRONIC DESIGN, Jan. 22, 2001, p.
This is the one I was looking for - the key was the author's name.
Unfortunately, no schematic...yet.
That sounds like a pretty interesting idea.
Maybe write to the author? I tried to find him, without obvious success.
I tried a few years back, via his university but got no reply, but I just noticed on a comment on another topic that he's still active (literally today!) so I'll try again.
