3D Printering: Print Smoothing Tests with UV Resin

Posted on by

Smoothing the layer lines out of filament-based 3D prints is a common desire, and there are various methods for doing it. Besides good old sanding, another method is to apply a liquid coating of some kind that fills in irregularities and creates a smooth surface. There’s even a product specifically for this purpose: XTC-3D by Smooth-on. However, I happened to have access to the syrup-thick UV resin from an SLA printer and it occurred to me to see whether I could smooth a 3D print by brushing the resin on, then curing it. I didn’t see any reason it shouldn’t …read more

Difference between legitimate file transfer vs data exfiltration of confidential files using FTP

Posted on by

I have FTP logs and some other logs assuming that corporate environment is actively monitored. How would I know that user is using ftp to transfer regular file and not using the same to transfer confidential file from an orga… Continue reading Difference between legitimate file transfer vs data exfiltration of confidential files using FTP→

Data Loss Prevention Needs a Little Help from Its Friends

Posted on by

I recently read an article on Security Boulevard discussing how to get the most out of data loss prevention (DLP) technology. While much of the byline I agree with, especially the three questions all organizations should be asking to understand their d… Continue reading Data Loss Prevention Needs a Little Help from Its Friends→

Hackaday Prize Entry: DIY DLP

Posted on by

The 3D printing revolution is upon us and the technologies associated with these machines is evolving every day. Stereolithography or SLA printers are becoming the go-to printer for high-resolution prints that just can’t be fabricated on a filament-based machine. ADAM DLP 3D printer project is [adambrx]’s entry into the Hackaday Prize and the first step in his quest for higher quality prints on a DIY budget.

[adambrx]’s current iteration employs a Raspberry Pi 3 and a UV DLP Projector, all enclosed in a custom frame assembly. The logs show the evolution of the printer from an Acer DLP to the …read more

Want Gesture-Tracking? All You Have To Do Is Lift Your Finger.

Posted on by

Watching Tony Stark wave his hands to manipulate projected constructs is an ever-approaching reality — at least in terms of gesture-tracking. Lift — a prototype built by a team from UC Irvine and FX Palo Alto Laboratory — is able to track up to ten fingers with 1.7 mm accuracy!

Lift’s gesture-tracking is achieved by using a DLP projector, two Arduino MKR1000s, and a light sensor for each digit. Lift’s design allows it to work on virtually any flat surface; the projected image acts as a grid and work area for the user. As their fingers move across the projected …read more
