Thanks again to Brian
at Hackaday for a new article about my 555/4017 Diode Steering tutorial!
February 23, 2015
The mighty diode has its
day! In this vlog I do a cool project to show how you can create
advanced display drivers using diode steering. I build a 555 timer
clock to control a 4017B decade counter as a start, build a couple of simple
display boards, and also get to use some of my cool vintage parts for an
advanced discrete 7-segment driver. Check out the details and schematics
on my science and engineering blog to build
your own project -
Special thanks to all the
people and institutions who have helped me with this project so far, with
very special thanks to:
Stephen Masucci - general
space nut and all around swell guy.

Taped more than 25 years
ago, here is the 50 Years of Television Exhibit at the Smithsonian as I
recorded it on September 23, 1989. Included are lots of early Televisions,
items from the 1939 New York Worlds Fair Futurama and the World of Tomorrow,
and some items from the history of early recording exhibit. No commentary,
just enjoy the ride. Shot in my early "blitzvideo" documenting style, where
I moved and zoomed a lot so that I could capture the most detail in a short
period of time, and during playback I could freeze frames to examine items
and read text later on. Freeze Frame! Try it.... Lots of weird talk from
strangers and you name it all included. Rendered from the original SVHS

Bil and I are back with
the Dinosaur Den 2014 Holiday Special!
I finally got around
to posting this video that I shot in August, where in addition to a teaser
about my Apollo DSKY display research project, which was the reason for
my visit, I also take a brief technical tour of the Air and Space Museum.
I wanted to examine this collection of historic machines that are seen
by millions of people every year in a slightly different way, by detailing
some of the technology close up that was involved in these priceless Space
artifacts. In keeping with strict accordance to Smithsonian rules
for photography I could not use a tripod or any additional lighting, so
I had to get really creative in putting this vlog together using a combination
of my smartphone, portable audio recorder (for sync sound) and digital
camera to document my visit. Lots of post production was needed to
present this in an entertaining format. My many thanks to the generous
hospitality and patience of the NASM staff and curators!

Here is a look into
some of the work I did over four hours at the Philly
Fixers Guild Repair Fair at the Shissler Rec Center in Fishtown, Philadelphia
on November 22, 2014. The philosophy of the Fixer's Guild is to promote
sustainability in the community by encouraging people to bring in their
broken things and we show them how to fix them free of charge. If
possible we hope to return their items to functionality at the fair, or
at least direct them as to where and how to get the item fixed rather than
discarding it. Bad gym lighting and even worse gym sound also
provided at no cost to you! Enjoy!

Just a brief update
vlog to let everyone know what I am up to and what is going on with my
YouTube channel and the Dinosaur Den.

It was great hanging
out with my oldtime Williamsburg friend and former Frantone employee Kyp
Malone at the TV On The Radio show at Union Transfer in Philly. And
double thanks to Kyp for giving me the super cool TVOTR Seeds double LP
with amazing Moiré pattern animated cover art and melted gumball
