  • All the 3W LEDs you stock are rated at 700mA. But this unit only provides 350mA. To get the full brightness from the 3W LEDs you need to desolder the surface mount resistor and change it ? Or have I misunderstood ? Perhaps you could stock different current rated units, or put a through hole resistor on the board for easy resistor changes. Thanks.

  • Do standard steppers fit on the various parts ?

  • Have I missed something. It might have numbers to 11, but it only has 10 divisions. It starts at 1 not 0? So in its minimal position it’s already at 1, with 10 steps, one tenth each ? Shouldn’t it be marked 0-11 ? So it can go from off to ten then 1 more to 11 !?

  • There was an “alternative locomotion” class. You could have entered one! I almost brought a walking bot, but I could make it fast enough and stable enough to complete the course in time :-) It needs longer legs …

  • I’ve posted the first of about 3 or 4 articles on my bot. I didn’t win :-), but I did complete the course. I’ll be posting circuit diagrams, code, etc, over the next few weeks as I get time.

  • Aaarrgh !! Always read the instructions THOROUGHLY ! Just finished building mine and noticed the push buttons have to be inserted a particular way, even though they have symmetrical pins ! :-( now I see the “Important note : For all the push-buttons, the side with two dips must face the end where power connector locates” in the instructions … where’s my solder sucker … :-(

  • This is perfect, except for being held in the US ! :-( Not great for us UK peeps. What are the chances of packaging up the materials and selling them ? I’ve offered to teach an introduction to microcontrollers at my daughters school. But I’m not a teacher. I would love to buy a pack of materials that includes some lesson plans and ideas ? Any plans to offer this remotely ?


    When are you guys opening a UK office !? :-)

  • Comments elsewhere seem to suggest these encoders contain mechanical switches ? rather than digital switches ? Is this correct ? do you need to debounce the signals ?

No public wish lists :(
