The E-beam gun has 4 pockets, they are driven by a bevel geared shaft on one side of the e- beam gun. One turn of this shaft indexes the crucible one position. Initially I was going to use a ferrofluidic feedthrough and a miter gear set to drive the...
On the smaller system I picked up a 1000l/s Pfeiffer turbo to put on it as well. It had a bad bearing and I picked up another one and installed it. Oil was a pain to come across, very specific for the pump, a fomblin. The biggest issue was mounting...
Finally working on the small system again. I did get the copper conflat seal and installed that and have not touched the system since.Couple weeks ago I decided to take another whack at the system. First issue I have found is the turbo is not happy after...
Let me start by saying that I found the idea on Reddit, but I'll be damned if I can ever find that post again.First up, cut your foam core to size. One full sheet will be the top, and another will be the bottom. Cut one sheet exactly in half, as these...
I tend to have very shaky hands, especially when attempting to take photos, so in addition to building a small booth, I also purchased a tripod (10$) and a macro lens ($15) for my phone. The tripod has a couple of features I really like. For one,...
Sorry for the broken photos in the previous logs. They should be fixed now. Turns out, if you upload from desktop-dropbox, Hackaday hosts the images, but if you upload from web-dropbox, the images continue to be hosted by dropbox. I could see them because...
So the PCB fabrication worked out nicely. I recently switched from using the toner transfer method of home fabricating PCB's to the UV exposure method because I wanted to make compact boards with small SMD components. My experience with toner transfer...
##########"Yay, it works. Mission accomplished! Get back to sleep!"my wife said."Wait, what about build manuals, documentation and high resolution assembly illustrations in open hardware projects?"".."##########Well folks, documented it shall be then...
Both Hoverlay I and II were completely layouted in Adobe Illustrator, a surprisingly flat 2D drawing tool I just happen to work with a lot. This is how it looks like, basically:Making all the parts fit without using 3D CAD required...
In a flurry of productive activity, I finished a pretty good looking (IMHO) extension to mount on the front of the adapter plate and a half-assed bezel bezel plate to hide the screw holes and give a "finished" look to the project. I'll add a couple...
This is an update that builds on the previous discussion of exposure and reciprocity failure. I don't claim to have written The Book on the subject, but referring to the previous log may help you understand the following. -----When last we...
Guess what came back from the workshop? Only issue is the hole for the INS-1 are a little bit small. Now doing final adjustments on the boards and we will have a first working near production model
To finalize the Bluetooth added feature, a small 3.3V regulator board was needed. Along with this, it was designed to also carry the voltage level shift and HC06 as a plugin.The voltage regulator is an LM317 adjustable supply. This allows for an adjusable...
Since the previous post, the first 2 flood boards have been built and used live at a concert (unexpectedly, but helpfully, allowing me to find where my protocol and approach has had some inherent weak points). To simplify, I shall just post an itemized...
If the picture isn't a bit of how I felt when assemlbing these little tricksters than the explanation will. The entire build except for one piece went smoothly. Some parts were no longer being sold so I had to improvise with better newer...
