Improved Filament Spool Holder (with optional motor)

If you need a spool holder that does the job and has an optional mounting area for a DC brushless motor, here it is. I still need some refinement of the motorization option. But it’s otherwise functional. Sure, there were quite a few other spool holders. None of the ones I browsed on Thingiverse had a license I liked. So I created my own. Feel free to use or modify it! If anyone has suggesti...[Read More]

Sealed 608 Bearing: Should You Clean It or Just Oil It

.I’m now faced with a slight dilemma. The 3D scanner table has been modified for a 608 bearing and printed out. And as it turns out the 608 bearings I intended to use are a gummed up with shipping oil. Should we clean out the bearings with Acetone? Or just drown them in some PTFE fortified 3 in 1 oil? That’s what I aim to answer in the next video, Cleaning and Oiling Sealed Deep Groove...[Read More]

Prusa i3 Mk3 MMU 2.0 Banging on Start

If you haven’t seen it yet Prusa’s i3 Mk3 MMU 2.0 printer module offers up multi-material printing using five pre-loaded filaments with a single extruder. The magic happens with a fairly ingenious filament selector module hanging out above the printer proper. And it works. The selector is adequate at selecting filaments and I’m not seeing much of an issue with it’s function...[Read More]

Cheapest EBay Filament! Good Deal or Total Junk?

In our new series of videos on YouTube we ask an important question. Is the cheapest PLA 3D Printer filament on EBay a shrewd deal or total garbage? Initially I’ve weighed out the filament. And over the following weeks I’ll be printing with the entire 2.2lb (1kg) spool to see if it’s worth your hard earned US dollars. So join me in the shop to see if the lowest priced PLA 3D Prin...[Read More]

Disable Middle Click to Close in XFCE4-Terminal

If you’ve used XFCE4 Terminal as a terminal emulator on the desktop you may have noticed an odd behavior. Every so often a tab will inexplicably close while you’re using it or floating the mouse pointer by it on the desktop. As it turns out this is a middle mouse button click to close. In my case it happens when I’m using the track pad. Or not using the track pad, as the case may...[Read More]

Eken H9/H9R/H9S Action Camera WiFi Connection

You may own an Eken H9 series action camera. You may, like myself, have gotten a few different lenses for it to modify it for your own, non-fisheye, use. But how will you connect to it either through a wire or wireless? All you need is an application (VLC will do) that can read in an RTSP stream (read more on those over at Wikipedia) and punt it to wherever you’d like. Be aware that you won&...[Read More]

Smoothieware Update for MKS SBase v1.3

While updating my MKS SBase v1.3 to the latest smoothieware software I ran into a bit of a snag. Not a snag you’d find in the actual (recent) Smoothieboards, mind, but a snag that would only occur with the MKS SBase. As it turns out they’re shipping with a 2014 copy of the Smoothieware firmware. Even as late as 2016! Because of this it won’t read a Fat32 formatted SDcard. Instead...[Read More]

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 “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?
