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.
CT Hackerspace Fundraiser
3D Printing Job / Gig
50 Parts – 50 Bucks Challenge
Our member Dmitriy has an option to print a total 3D printed parts for his company. In return, this could be a great opportunity as a fundraiser to help our space.
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.
Halloween is right around the corner and we all have to get our holiday related projects finished.
So what better way than to have a micro hack-a-thon to get that final push in?
