Around the end of October, I finished up the design of all the plastic components which would house the electronics of a 200W x-ray system. It was now time to design those electronics!Back in September, I had an idea of how I should go about doing this....
Well exactly 98 man hours later, (avg. 14hrs per day*7,) and These are the 2 primary modules and I included the CLI (communication link interface) I had to make this so I could connect the CCD module with the ADC module.This is the CCD module (1) This...
woody is using BMX cranks because they allow very small sprockets. Below is one of two assemblies before welding. The bottom bracket was turned on the lathe, and the two plates were made by sendcutsend. And here it is bolted in place. The holes...
Mike Jouppi12:55 PM Mike Jouppi12:55 PMOk, here is the board stack up Sven F12:55 PMOK, thank you very much. Your links are already helping me! Do you know any surface mountabe heatsinks manufacturers, too? So far I used some BGA-heat sinks and mounted...
Finaly the prepping of the dashboard is complete :) Everything is solderet and connectet to the circuitboards. So now i am just wating on the wood i have orderd to build the frame :)
After quite a bit of delay, and a vacation, it's time to start building. Just about all the parts to build V2 are here and so I am moving forward. All metal extruder, all metal frame, all metal everything. And....a Rasberry Pi running...
A decent amount of craft and prototyping,hacking went to fabricating square matrix of LEDsfirmly attached to massive passive planar square heatsink.Two hacked boost power supplies are tuned,CC power supply frame-heatsink construction under way.all savings...
Getting stuff done when you're watching your niece and changing diapers isn't an optimal combination! But I managed to write a little library that handles the display driving etc. So now I have to reprogram everything I had running before, like the enemies...
This buck is fresh off the printer, I did another test fit and things are looking good. I went ahead and started the printer for the frame buck which we will not see for a couple days because .1mm printing is SO SLOW , but the results are desirable. ...
The first part of Wheatly that I built was the TAD or Track Attachment Device. I wired up 2 12v motors to turn at the same time. I 3d printed a frame and used metal rods to attach everything. This way everything is adjustable so I can fit it to the wooden...
I replaced the Chicago bolts today with normal 1/4" bolts + nuts. I found the Chicago bolts were coming undone quite easily, and since you could not tighten each section (frame / leg / frame) independently, the entire leg assembly felt a bit sloppy....
Space is tight so everything has a fixed place. First i used tie-wraps to secure the wiring but then the frame wouldn't fit in the case no more, now i'm using very strong yarn which works fine.A ethernet cable just fits in its slot
I used the CNC mill to machine the adapter plate today. Everything went smoothly but I forgot to take a picture of the final piece. I did take a cool time lapse of the final frame milling operation. We don't have the coolant system hooked up yet so it's...
Quick update, files are uploaded so feel free to make your own or modify to your heart's content. I'll add the 3d printed frame stl/solidworks files shortly, but everything else should be good to go. I originally wanted to make a kit but I just don't...
4 pounds 5 ounces, it is light considering everything that is on here! In retrospect in the future I would do the prefiltering and the voltage dependant resistors and capacitors on the ground before the tether. It is not as effective because over the...
