  1. @@lawrence_jeff, @@Rhys Hi guys and thanks for your work here. I know this is an old thread, but I've got a couple of question's and maybe you have the answers. I've used the supplied code for building an arcade control encoder for a raspberry pie arcade cabinet. The controls consist of 2 classic arcade style joysticks and 14 buttons, 1 joystick and 7 buttons for each player. I've written the device report descriptor to send 2 report ID's 1 for each player. When I plug the encoder into a windows machine it enumerates as a game pad with 2 controllers and everything works as expected. Wh

  3. great job @@greeeg
  4. Great work thanks for sharing!!!
  5. Very cool project @@greeeg
  6. @@terjeio very nice, I like the pcb printer very much it's so ....cute. I would like to replicate it. Those actuators are not cheap though. Thanks for showing it off!
  7. This looks awesome @@terjeio. I really like diy CNC machines and would like to see your machine. I've machined a couple of 2 sided pcb's and had good luck re-aligning the 2nd side. When I layout the pcb I put in mounting holes for a small fixture I made. Then I bolt the pcb to the fixture run the 1st side, pull the fixture out flip the boad and reload the fixture. It works pretty well. 1st side 2nd side through holes line up pretty well! finished! heres a shot of my robot thanks for posting your project, you've got me thinking about putting a laser on my printer.
  8. Are you absolutely sure the lcd is connected correctly? Are you using the boosterpack @@Rei Vilo used? If not the connections could differ. From the looks of it @@Rei Vilo's library has been proved to work. I would re-check your connections. good luck!
  9. Great idea! Good thing your 1 left over pin was an ADC pin!
  10. Yea the Toyoda is an awesome machine and I wish it was mine. It's a pleasure to run it. It would not be effective as a laser cutter, and your right it wont corner that fast but, its amazing the speed at which some of , most of the newer large CNC's move and corner at.
  11. Oh Yes! We may have something in common there, machining metal while listening to metal! That would be great if the laser could handle it.
  12. Thanks for your opinion @@Fred! Here are a few more points to consider: Every industrial cnc I've seen seems to have ball screws, they are fast, and rigid. The Toyoda FA400 in the shop I work at rapids at about 2300 inch's per minute(59 MPM). This machine will easily take a .5" deep pass with a 1" cutter at 100 inchs a minute through 7075 aluminum all day long. I think that qualifies as rigid. Yes I know this example is not a good comparison to a small desktop machine, but just from the video and what the guy says in the video it would appear the ball screws are of good quality
  13. Just saw this , seems nice. https://www.kickstarter.com/projects/boxzy/boxzy-rapid-change-fablab-mill-laser-engraver-3d-p?ref=category
  14. Hi @@pallisi, It sounds like the pin assignments are wrong, Its pretty easy to check though, only 4 pins. From the picture on RobG's tindie page it looks like the 4 configurable jumpers are: JP1 for the display chip select, you want to jumper that to gpio19 (J2_2) on your c2000 launchpad. JP2 for for the D/C select, you want to jumper that to gpio12 (J2_3) on your c2000 launchpad. JP3 is for the backlight, It looks like that could go to either J1_8, or J1_10 on the c2000 launchpad. Both of which are ADC inputs , but they can be configured as gpio. Thats not in the code I sent you thou
  15. Hi @pallisi, Nice work on finding the SPI_write8 function. I don't know why some of the libraries have it and some don't. Since you have the V3LCD , you will have to configure it like the V2LCD. Thats the one I have. Make sure MISO, MOSI, SCLK, and CE go to the correct pins on the boosterpack. It looks like its configurable with solder jumpers on your V3LCD. Also the lcd controller on the V2LCD is the ILI9225, is yours the same? Or is it the ILI9341? If you have the later you will have to grab Rob'Gs library (http://forum.43oh.com/topic/4352-universal-color-lcd-graphics-library
  16. Hi @@pallisi Ok I had to look for it. It's been awhile , and looking back the code is a mess. I commented it pretty well though. Im not sure which LCD controller you have but the one I have is ILI9225B. So if thats what you have it should work out of the box. The attached project is set up for software chip select, its the same pin as hardware chip select which is noticeably faster. I suggest trying both. You'll just have to comment or uncomment a couple of lines to get it working. Also if you have the 2.2" lcd with touch I have some code for that too. One thing at a time though.
  17. This looks pretty neat too. Not much Z travel though. https://www.inventables.com/technologies/carvey
  18. Very Nice! I'm right on the verge of building a quadcopter. Need to keep it low budget though.
  19. Did you try : http://e2e.ti.com/support/microcontrollers/c2000/ Being that the energia port to the C2000 is in its infancy, maybe it's time for CCS?
  20. I like this one: http://www.ti.com/product/tmp100 +/- 1 degree Celsius , 12 bit resolution . I2C. Pretty easy to use, lots of I2C examples in the forum. I even got some free samples of it from TI!
