Moving around LVM2 Partitions (and Changing their Size)

Recently I ran into an issue where the size of an existing disk images LVM2 partition didn’t fit. The latest hardware from our vendor didn’t contain a large enough SSD memory drive! Since I didn’t want to re-create the entire image I turned to the Internet for help. My issues with pre-created images aren’t infrequent. While it’s not as much of a problem currently as i...[Read More]

Max6675 Housing (3D Printed) in Translucent Green PLA

While working on a temperature controlled oven for drying out desiccant and plastics I needed a housing for the Max6675 thermocouple controller. I also didn’t want to adapt something to fit. Being in possession of a 3D printer I figured that was just the solution to the problem. Fortunately someone over on Thingiverse (bradford) had created a design that contained the measurements. A small b...[Read More]

Fixing WebCollage Screensaver Headers.pm “Use of uninitialized value $vals” error

Tired of getting errors scrolling down the screen in the WebCollage Linux screensaver? So was I. WebCollage (here’s the link to the .deb on Ubuntu), for a bit of background, is a nice Xorg screensaver for Linux that displays a random collage of images fetched from various search systems on the Internet and popped up in an array as a screensaver. It gives you a weird and occasionally surreal ...[Read More]

Creating Mr. Beams Networked Lights Hacks

Mr. Beams produces an inexpensive line of autonomous outdoor lights. Coming in at 25$ each and 47$ or so for a pair they’re decent bang for your lighting buck. But what if you’re not satisfied with the product out of the box? What if you’d like to completely void any warranty provided with the product? Possibly break it horribly?

3D Printing: 3D Printer Build Plate Leveling

3D printers require a level build plate. We’re taking a look at how you can level your Replicator, CTC, Flashforge, or other Makerbot Replicator style printer build plate Bill of Materials for this Build: Finger Guage (or sheet of paper) (Digital) Dial Gauge 3D Printed Jig Small Magnets (optional) Hot Glue (to adhere magnets) Some newer extruders such as the Kossel style Deltamaker cleverly ...[Read More]

How To: Run a Benchmark on Linux

So you’re wondering how fast that new Linux desktop you’ve built is.  But you’re not sure how to run a quick benchmark and find out. Maybe you’re not familiar with the programs you should use. Maybe you’ve never actually run a benchmark before!  In any case we’ll go over a few basic benchmark tools that’ll have you comparing real world and synthetic perfor...[Read More]

Cleaning your 3D Printer’s Feed Drive Gear

While 3D printing there are few things worse than getting half way through a print and realizing that the filament is getting stuck in the drive gear.  Which happens when you’re running cold filament on a hard metal gear with relatively sharp teeth. Which leads to the need to clean out the drive gear!  Keeping the drive gear clean can help the filament keep flowing in the right direction and...[Read More]

3D Printing: Replicator Windows Hinges

Today’s Makerbot enhancement is a window hinge from Thingiverse complete with custom cut acrylic windows. You’ll have noticed them in the previous post’s CTC Dual Extruder 3D printer. These clips seem to work well even with the under-sizing you’ll get on converting from metric to SAE sizes. What you’re seeing there is the combination of these clips and this acrylic wi...[Read More]

CTC 3D Printer in Action

Replicator style printer from CTC printing a rectangular test print. And here we can see CTC’s 3D printer printing out a 10 by 40 mm (10mmx40mm) test block to gauge how accurate it is.
