THE ANALOG THING
A lot has happened since our first THAT newsletter was issued a few weeks
ago, so it is time for an update (we now have more than 800 subscribers
which makes us really happy and proud).
Production and ordering
Version 1.2 of THE ANALOG THING circuitry and PCBs has been finalized.
This is the version that will go into production. It fixes some minor
issues that showed up during extensive tests of the prototypes. It also
introduces additional circuitry to protect THE ANALOG THING against

THATs will be fabricated in batches of 100 pieces each. The first such
batch will go into production in the next two to three weeks and we
expect delivery in February 2022 if all goes according to plan
(we, too, are affected by the current shortages of electronic parts, most
notably ESD suppressor diodes but operational amplifiers etc. as well).
If we get more than 100 orders (we already have about 15 orders in our
queue) additional batches of 100 THATs will be ordered subsequently.
These will then become available (with a grain of salt regarding parts
procurement etc.) in April/May 2022.
THE ANALOG THING already has provisions to facilitate its use as part
of a hybrid computer setup. An example adapter circuit for coupling
a THAT with an Arduino Mega 2650 board is described in this
article. This example also contains the required firmware for the
We also have a new analog computing application note introducing the
"exponential mapped past" approach developed by Otterman in the 1960s.
This advanced (and clever) approach allows computing mean, variance and even power spectra
on an analog computer. If you have the need to process stochastic data
that way you can easily use a THAT for that purpose.
