Fruit Jam, Zork and the Z Machine
In the 80's before ChatGPT, gamers had another way to have conversations with their computers: Zork and Z Machine games.

Mac emulator, I am reminded of that time I won 2nd place at the MacPaint Olympics in college. The prize was an Apple mug, which I still have. From the June 4, 1984 issue of InfoWorld.

We put a man on the moon 50 years ago, but we can’t design a foolproof power strip.

Lots of progress on my
@circuitpython.org
game for the
@adafruit.com
Fruit Jam. Premise is you mine for minerals on different moons. Have a title screen, mechanics working, multiple page game working and a few animations. Next up is to fix bugs, add additional levels and animations.

One of my early
@circuitpython.org
projects and still one of my favs. The EZ Make Oven is a reflow oven for soldering surface mount components to PCBs built from
@adafruit.com
parts with no high voltage wiring. I've been using it for over 5 years. Learn guide here:

Fun fact: The first
#shareware
program I wrote was a blackjack game for the
#Amiga
. It was distributed using Fred Fish disks in computer clubs and BBS’s and people would send me money in the mail for the deluxe version and I would mail the game to them. Pre-Internet times seem like a lifetime ago.

Fun fact: text stored in a story file for a
#ZMachine
game (i.e.
#Zork
) is encoded as 5 bits, so 3 characters could be stored in 2 bytes(16 bits). Every byte counted back in the day. Didn't know there was a history using 5 bits for text. Thanks

My college years saw big changes in computer technology. As a freshman we used punch cards for computer assignments. Later years we switched to terminals and in my senior year the Apple Macintosh 128K arrived on campus.

Finally I have a video captured screen shot of my CPZ Machine playing
#Zork
. The font can be changed in the program. The included fonts allow screen sizes from 64x22 (this screen shot) to 106x40 characters.

There was not a single reason why I became an engineer but looking up at the moon when I was a kid 56 years ago and saying to myself, “there are people living up there”, was one of them.

Not my typical project, but I created this magical

bag about the story of

. There are a total of 10 story panels and 5 bag changes. I used
#inkscape
for the drawings and printed it on custom fabric. I’m making a few so pm me if interested in one.
