So right now I've designed the case and plate in Solidworks and will be 3D printing them. I'm not sure exactly how well everything will fit, so the first print will basically be checking to make sure everything does fit in the way I intend.
Today I finished project design and sent everything to fabrication. I ordered PCBs from OSH Park (5$) and kepton stencils from OSH Stencils (8.45$ with shipping). I expect to get everything ready for assembly in next 20 days. Till then, over and out!
Massive delays. I did not route with forethought, meaning that I2C pins have been allocated already. There are options that are equally bad, (1) Reroute everything and change the animation programming, or (2) bit bang I2C. Another set back is that I...
Today I succesfully mounted the Nema 23 motor, everything worked as expected :) Next step is mounting everything back together for first test and see if force has been improved over the Nema 17 with 6mm belt:
After having printed another robot, it still couldn't fit our accelerometer. So we decided to change the design completely. Then printed it, and everything fits. We finished the code as well, so now everything needs to be assembled. We also cut...
7/29/2013: As I stated; been working on the cabinet for the Mirror universe project. I bought a couple of "project" Bally Star Treks from a fellow pinball collector out of Shertz a few years ago. These have been setting in storage for a while... and...
In this log, the first renders of the pcb layout are presented and a major change in the design. First off, the change was that we changed the FPGA package as obviously the 484 pin was an overkill for this design. The package was switched for the 256...
The first attempt at this type of printing was done by someone on the Lulzbot forum back in 2013. Back then they didn't give any particular consideration to the material properties of the molten metal, which is why they couldn't get past the clogging...
I have the budget to finish out the robot. I have the base aluminum panel, the 6 axis arm and the linear actuator/slide mech for the raising and lowering of the arm at ~12" with a future capability of 18". The arm raise mechanism took a lot...
What Is It?The Intel SDK-85 is a single board computer trainer from Intel. It is very similar to the MOS (later Commodore) KIM-1 in that it features a keypad and 7 segment display. 2K of ROM and 256 bytes of RAM are provided...
There is a major limitation with circuit schematics: 3 circuits (with the same schematics) may have significant performance differences which are a result of the physical layout of the circuits. Therefore it can be said that how a circuit is implemented...
Alright here we go! In case you missed the last log, here it is! Check it out because what you're about to see will make a lot more sense. Just like the last log, this log is going to be a retrospective, but I promise that the next CRAPi2040 log to grace...
1/2/13Today, I finished soldering everything onto the board. After the Arduino was on there, I tested the throttle joystick and IR LEDs to make sure everything was connected properly, and it was. Next was the accelerometer. I hooked it up and that worked...
Supposedly, I should be able to screw everything together, but since the CNC shop can't make that M3 threaded hole, i'll just glue everything together. No biggie. However:DO NOT STARE AT THE HEAT LAMP!!! this is from my own bloody experience. Just do...
