I just did another Instructable – Easy, Reversible Motor Control for Arduino (or any Microcontroller) (wow – that’s a mouthful…).
It is the result of my effort to come up with something less annoying to construct than an H-Bridge – using just locally available parts … (read more)
This project is a variation of my arduino powered laser show – and honestly it’s not quite as cool. But – I wanted to go down this road to explore a few ideas…
The video really covers all the core technical details:
My original hope … (read more)
I have finally gotten around to documenting my Arduino powered laser show that uses audio speakers for Galvos.
Full documentation and source code is available via this Instructable.
Quite happy with the way it works now:
The “home” for this project (and it’s Twitter … (read more)

Turns out my new Thorite sample emits a fair amount of Radon 220 (aka Thoron)…… (read more)
Update: The cloud chamber is currently not for sale – but is being re-engineered as a kit. See https://nothinglabs.com/cloudchamber/ for info on building your own!
Cloud chambers let you see paths left by ionizing radioactive particles. Traces appear as the … (read more)
I registered nothinglabs.com about 3 years ago with the intent of morphing my translational drift project into some kind of flying toy.
In a more general sense – I wanted to somehow brand myself with something other than my circa-2002 now obsolete totally awesome anti-spam … (read more)
I got the laser show working pretty well now.
Not shown in video – but it also has a full library of alpha characters – so it’s easy to do text.
Full documentation / schematics coming soon!
Made a lot of progress since the last post:
No radical changes – just a bunch of minor tweaks adding up to better performance.
Will publish code / details in the next few weeks.… (read more)
A week or so ago – I found one of these at Value Village for $2.
If it’s not obvious – it’s a little laser show toy. It projects a laser on the wall which moves with sound / music. Unfortunately they don’t seem to … (read more)
Latest round of design tweaks + some slow motion footage:
Hello – my name’s Rich.
“Nothing Labs” is the name I do a handful of things under – some commercial, some fun – some in the gray area between.
I’ve mostly started blogging again so I can easily share things related to the fun stuff … (read more)
