  1. FAAAAACK! Gotta sooper sleuth the Gee Dee passive values. Seriously, it doesn't cost a thing to have them in the schematic.
  2. I'm putting this together now. BOM is horrible. What values are ALL the resistors? P.S. Why, why why SMT? PITA, no?
  3. "@swampdonkeykami Thank you for the review!" You may be mistaking me for somebody with an obscure youtube channel.
  4. Got an interesting problem with my second kit. Turn on. No display. randomly mash buttons. displays 0000000 for split second, then blank. Check power and pin voltages... 1- 3V 2-7 1.3V 8-13 0.3V 14-15 1.3V 16 3V 17-18 0V 19 0.3V 20 0V I assume I did something wrong like insert LEDs wrong way. Start cutting leads off (hate de-soldering) Bingo. LEDs light up missing a couple segments. LED installed correctly. Faulty/fried bubble module?
  5. All good! Wrong tongue angle. Love the programmable easter egg! Well done.
  6. Got my two. Chips no flashed? I must have mis-read that they were flashed... Is there an Energia sketch, or am I forever destined to be the dumb kid eating paste in the corner?
  7. i'll buy 2 kits. bluehash---------------1---------US cubeberg---------------2---------US GeekDoc----------------2---------US Greeeg-----------------1---------AUS Swampdonkeykami----2---------CA
  8. I'm in for a deluxe version. Let me know where to send da moneys.
  9. *thinking* or we could install a pressure transducer and have the 43oh calculate the volume of air @ X pressure and base all movements on that baseline pressure, then don't need any fancy geometry algorithms for axies! THANKS FOR THE INSPIRATION GUYS!!!!!
  10. Glad you like! More fun in the works! No, this came out of a gold mining machine. I'm re-purposing for something completely useless. ;-) As for varying loads, yes and no. If you are talking lifts various weight of items, shouldn't make a difference because the cylinder volume is constant. You put in 3 litres of compressed air @ 30psi, the cylinder moves 500mm. You put in 3 litres of compressed air @ 200psi, the cylinder moves 500mm. The trick is, the 43oh needs to return to a known position (full retract, full extend, or limit switch) prior to changing the load. But if the load v
  11. Now that we know it works, I'm bustin' out more cylinders and joystick controls! :thumbup:
  12. Hi Guys! I've been toying with an idea, that I didn't think would work, and set up a test jig. Using an air compressor, a solenoid valve, a flow meter and a 43oh I found that we can get a repeatable cylinder position, like +-2.5 mm! The flow meter is measuring the volume of air that we've fed to the cylinder and the 43oh opens or closes a solenoid valve depending on the cylinder position.http://arduinoforgoodnotevil.blogspot.ca/2013/10/accurate-ish-pneumatic-cylinder.html
