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...
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...
After a few trials of the claw to pickup cans with short extensions (removing the longer brake line fingers and using the intermediate linkage with short extensions as the fingers), there was a need to extend the reach out further. Deciding to extend...
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...
This build started with optimizing DSP operations on 8-bit Atmel MCU. floating point is too slow, so i designed 16-bit fixed point arithmetic with optimized assembly language inline multiply. Exponential rise-fall dynamics are hard to calculate directly,...
The first real pcb made with the mill is for a tiny robot. It includes such milling challenges as 0603 smd resistors and SOT-23 transistors, as well as a narrow trace running between two 2.45mm pitch holes with pads.As intended, this shows the limits...
