CTH received a donation of an old Jet 16 Mill/Drill. It was in rough shape. In addition to needing a paint job, there were also some pieces missing, including the Drawbar. Used drawbars on eBay were in the $100 range. Instead of ponying up that cash, we decided to make our own drawbar. We have an entire workshop at our disposal, right?!?!?!?!? Continue reading
3D Printers are the best! The appliance adventure I experienced today proves that statement.
My neighbor has a GE Aurora Clothes Dryer that ‘stopped working’. The reports were that the Start Button was becoming increasingly finicky. My gut reaction was that the physical switch was going bad. Well, in the end I was wrong about that, learned how not to design a dryer and gained even more appreciation for my 3D Printer. Continue reading
The 27-May 3D Printer Workshop at CTH went well. Our new pal Josh brought in his older AirWolf 3D AW3D XL printer. This thing has a huge 200×300 mm heated build plate. However, the build plate was a PCB-style which flexed and warped when heating up. This gave an inconsistent print surface height. If you’ve printed before, you know the height of the print surfaces has to be pretty darn consistent to get first-layer adhesion. Josh bought a replacement aluminum build plate, but unfortunately, the mounting holes were not the same! We can fix that… Continue reading
My beloved Afinia H-Series 3D Printer has not been working for several weeks. The bed would not heat up and the printer would not start printing because the bed was not up to temperature. I took the opportunity at the CTH 3D Printer Workshop to troubleshoot the Afinia. Well, I found the cause after a little disassembly. Do you see a problem here???? Continue reading
I bought the Bose Quiet Comfort QC15 headphones about 5 or 6 years ago. They are great. However, one of the ear pads started coming apart, and no sooner did that one finish unraveling, the other side started. The headphones were still usable but much less comfortable and didn’t stay in place on my head. eBay has ‘replacements’ but the comments regarding the fit were not flattering. I figured it would be worth trying to fix them on my own, because, well, I’d have to order some crappy replacements anyways so I might as well really ruin the originals first.
It’s winter and the air in my house is dry, humidity at about 30%. That’s too low to be comfortable. I’ve lived in my new place for less than one year so the low winter humidity hadn’t been a problem for me yet. Good thing there’s a whole-house humidifier on the forced-hot-air heating system. I’ll just turn that on, right? Wrong. I don’t think this system had ever worked since it was installed…. Continue reading
I admit it, I’ve left my garage door open all night… a few times. Doing so leaves all of my precious spare parts exposed for the taking! And maybe more importantly, provides access to the inside of my house…. not a good situation. I’ve been thinking about making some sort of indicator (inside the main house) for when the garage door is open. This would alert the home owner (me) that the garage is open.
After thinking about it for a while, I believe I came up with the simplest way to do this….
Some Graphics Cards for desktop PCs require a lot of juice to work, sometimes even more than the PSU Power Supply can output. And if you decide to run dual monitors with dual Graphic Cards, then one Power Supply may not be enough. There are a few options to elevate this situation. Purchasing a new hefty PSU would result in a tidy but expensive solution. A more DIY-friendly and significantly less-expensive solution is to add a second PSU (which you probably have kicking around) and delicate the 2nd PSU to your Graphic Card(s).
There is one tricky part to doing this, the PC motherboard controls when the PSU turns on and off. This post will go over how to automatically turn on/off the 2nd PSU with the PC.
