So, I have scrapped the idea of getting this supply running for the e-beam gun. Finding a tube has been very difficult so I picked up a Thermionics EBPS15, 15kw, tetrode electron beam power supply to do the job, it is good for up to 10kv at 1.5 amps....
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 the previous demo videos of the gimbal, I was using a separate platform (PIC32) to operate the servos. To consolidate resources, and simplify design, I wanted to transfer the servo operation to one of the Raspberry Pis already on the gimbal.A few...
As I gather more documentation and pictures for this build, it is planned to add later on. As for now:Hardware:Processing power 16F870 @ 20 MHzLimit switches gnd out the PICs input and inputs utilize a 1K pull up resistorPIC sends step/dir signals...
Since day one the claw machine has had random lockups that I thought a watchdog timer would fix.The three lockups that were seen were:Button for claw drop would not activate claw drop routine. This was resolved by using the watchdog timer and to...
Now that the boards were complete, the boards could be wired into the box. The boards were designed to keep the 5V power supply voltages separate between the two boards. This required 2 separate 5V power supplies to feed the control voltages...
To aide in testing of different setups/toys and claws themselves, the following features would be nice to have in the program:1. Use pwm to start off closing of claw slowly and go to full current after a predetermined amount of time. (Fade...
The following has been implemented:Allowed for communication with Claw machine mode via RS232 using the following menu structure:prog Enter into programming mode. Game play will be suspended after push button routine is finished (normal claw machine...
In the prior log I shortly stated that the app was going to be made from scratch. This would be a deeper look into the app programming structure that I don't have the time for. Fortunately, MIT's App Inventor 2 is available for use. With this program,...
I've always wanted to make my own Atari cartridge, and this project is a perfect excuse to give it a shot. I have some old Atari development cartridges I bought on eBay, which unfortunately accept only old eproms that dont match the pinouts of...
Now you can build firmware with: IAR ARM 7.2 and upper, CooCox 2.x, Keil 5.x , GCC ( tested with 4.9.3 ARM toolchain )p.s: firmware totally tested only with IAR, other build not fully tested, but must works OK
After some compromising due to budget (I suppose this plagues a lot of us DIY folks, at times), the flood panels have been put on hold. However, this resulted in forcing me to re-think how I was approaching this project and relatively simplify the mechanics...
Greetings! First of all, I'd like to thank the ~25 followers this project now has. Usually people don't give two shits about the technical details of my electronics projects, as they just want to see footage of it working; I understand it's not everyone's...
We're currently working on v0.3 of Moti's hardware.Here's the major changes. - Magnetic encoder replaces mechanical encoder. v0.2 used two continuous pots back to back to give 360º coverage. These pots were prone to misalignment, and...
I haven't posted an update in a long time, and people suspect that the project is dead. Actually, it isn't. I got busy at my job for most of 2015. But things died down a bit this year, and so I've been pushing ahead on the project, revising both the...
