[R] Contact Image Sensor for coating detection
Log from SecSavr Suspense [gd0105]
I was actually looking at a project that desired to 3D print by scanning a laser dot over the vat when I thought that I should see if I could implement some kind of sensor to scan the applied layer on the PET film. This is to allow the printer to...

A Better Sheet
Log from Analyzing the Hackaday Prize 2015
A new and improved spreadsheet is now sorted by project, instead of by contest, making it easier to sort and analyze (no more double entries!) Get the spreadsheet, it looks much better. Download the new one here. It has presorted sheets for most Skulls,...

In the process of learning how to recycle plastic, I've learned a TON about what plastic actually is, how it's made, what it's made of, and why the different types have the particular (sometimes peculiar) properties that they do. It's not only...

A Wearable Muscle-Machine Interface Based on Forcemyography and Electromyography
Log from Wearable, Soft Robotic Exoskeleton Gloves
In order to control the proposed motorized exoskeleton glove, an Electromyography (EMG) and Forcemyography (FMG) based wearable sleeve system was developed (see Fig.1). The sleeve interface is equipped with 3 bipolar EMG channels and 5 FMG sensors....

Log from SecSavr Suspense [gd0105]
You may be wondering why it sounds like I'm once again considering increasing this SecSavr Suspense lineup when I haven't even got a working prototype, but it shouldn't be that much of a design alteration since the idea is just to put a Y axis stage...

Revision A Summary
Log from Luggable PC Mark II
The goals for revision A were modest: just see if everything fits and works together. So a simple skeleton was built for everything to fasten to, in roughly the layout that we'll refine in future revisions. Make sure the simple thing works before...
