Hey all!This is another project log to update the latest developments of OWL (Just in case you forgot, we call it OWL because, well, Open Indirect Ophthalmoscope, OIO).So, since the last time I made a log, we’ve been working on--making an elegant GUI...
Once we had the car in our possession, it was time to strip it of unnecessary components. First on the chopping block? The engine.→InsertImageNormally removing an engine is a bit tricky, but luckily my friend has a big garage with an underground car...
We did it. We took a 1993 Honda Del Sol, and a equally old electric forklift and merged them together into something we like to call the Delsolectric Car.→InsertImageIt might not be pretty. But it worked. We even managed to get it up to 100km/h on the...
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...
The biggest issue to getting this thing working has been the Electron Beam Gun power supply. This gun wants 10kv at up to 1.2amps to run it, thats 12KW! Not easy to do. I looked at trying to modify other stuff like ion pump power supplies, built voltage...
Package Arrives!So I received my package from Newark on March 25th. Here are the new goodies that I got:One thing which I did not expect was the reel of resistors. Previous packages came only in a cardboard box with some foam. No matter since I can always...
OK, so more progress has occurred in the last 3 days than in the 6 months this has been running...I have now tidied some the cabling and built the unit back into it's original case.I was really lucky and found a 12v switched (powered on and off with...
"We're back baby !" for our second update after two weeks since the last project log.Things are real fine, we actually received most of the components we needed and were able to get to work on both hardware and software sides and so we were able to code...
This update has been a long time coming. Although I had roughly this leg drive system in mind since the beginning, it has proved quite fiddly to implement, as mechanical things often are. My plan was always to use a servo converted to continuous...
There was not a lot of space left in the chest after installing the arm servos, but they couldn't go anywhere else. The next biggest things are the batteries, so they needed to be placed next. I tried all the orientations I could think of, the only way...
So, I have been trying to experiment a little to get a more bakelite like appearance. While playing with some scrap, I stumbled on a combo that actually works pretty good and is pretty easy.What I did was go over it with a flat black spray from a great...
04.17.2014 (Kittan)Today was an interesting day. Well, not really. I got the housings finished up for the screens and all screens mounted within said housings. Last night we loaded some debian on the NotSoGreatway and found it lacking driver compatibility,...
04.20.2014 (Kittan)Got the easy ones mounted on the frame. I'll need to add a second row of rail and figure out how best to mount the bottom 5 screens (making sure to leave room for keyboard arms and accessories), but it should be done sometime Monday....
Step 2: Motion. This post is actually a long time coming, as I did some of this assembly a year ago. I have added gears, steppers, end switches, and RAMPS board. LM8UU linear bearings are from vxb.com. I had the top bearings on-hand. They are standard...
