National Ham Radio Field Day - Bill
Ragsdale
"The National Ham Radio Field Day is an annual exercise for
emergency communications with 30,000 operators participating. I will give a
short, live walk-through of my radio station. I'll show the 10 kW solar power
trailer, two operating stations, and the antenna arrays."

Tales of the Qiskit Hackathon - Jack J.
Woehr
The 2020 IBM Quantum Challenge hosted 1,745 participants who used
Qiskit to run 5,054,517,692 quantum circuits. The participants deployed an
impressive variety of techniques, including machine learning, to tackle the
most difficult exercise, optimizing a unitary operator derived from a 16x16
matrix to run efficiently on 4 qubits.

Update on New Robot Board Design - Don
Golding
"I have changed the processor on the robot board to an ESP32
plug-in board per a suggestion by Dr. Ting. The robot board's schematics have
been updated and I have just finished Version 4 of the layout. The new boards
(35) have been ordered from PCBway. My goal is to have these boards available
next month for $50 donation."
"I will also give an update of MadeInSpace. Moving to Florida
has really opened up opportunities within the company."

Extending Forth: An Integrated Editor and Contract
Generator - Dudley Ackerman & John A. Peters
"In 1980 I was
wondering how I could extend Forth to make something better than a spreadsheet
or a database program for making electrical estimates. After 30 years of
successs."
"The Contract Generator is an estimating program that’s
totally written and Forth with many custom extensions. It is a Win32Forth
program with the editor WinEd that makes it easier to create an estimate. It
automatically prices things by looking up the time required to install and the
price of the parts which are all in the dictionary as individual words. Then it
totals the numbers and breaks it down in to man-days, parts wholesale and
retail, and more."
"I wondered if we could have Forth in the cloud and accessible
from a browser. Dudley and I will show you how far we have come."

How I Use Test-Driven Development in Z80 Assembly
Language - Samuel A. Falvo II
"I'll present proof that you don't
need sophisticated testing frameworks to make use of Test-Driven Development
(TDD). Here, I'm using it to write a new Forth interpreter for my VDC-II
project. VDC-Forth is not close to being finished yet, but what code does exist
is known to be stable and trust-worthy."
"This presentation originally started out as a 15-minute Zoom
presentation for the Silicon Valley Forth Interest Group. I quickly realized,
however, that the material I wanted to discuss couldn't fit into 15 minutes.
So, I decided to make a video."
