  • When will SparkFun stop putting the battery plug on the same side as the USB power plug. Makes it impossible to design a decent enclosure for any product with this flaw.

  • Really great product. It is well designed and easy to work with. It is fun to drive and is my kids favorite Sphero product by far. My only complaint is that the battery takes far too long to charge through USB, and there is no option to charge the battery using a external balancing charger.

  • I just discovered that this little remote really has 21 buttons, but only 9 of the 21 buttons are available! It would be a killer feature to have a cheap IR remote like this with at least two button plates: 1. The standard one you have here 2. One with all 21 buttons with generic labels (grid style A1 - C7) or (the HEX codes)

    Also include little stickers to put over the buttons so we can customize our own remote. :)

  • Even though it's "stupid" it sounds like it was a lot of fun to make. I am interested in one of the extra Pro Micro-ATX boards and expansion cards.

  • This is a great tutorial. I've etched a few circuit boards at home, and even etched aluminum for another project, using Copper Chloride in Aqueous Hydrochloric Acid Solution. I came across this better etching solution, IMHO on You can check it out here, Stop-using-Ferric-Chloride-etchant!.

  • Great product, especially since it drys extremely fast compared to other pens.

  • Cool!, they used Circuit Scribe Conductive Ink Pen (~55:12) but didn't use it in their valentines projects...

    Though they do mention Circuit Scribe earlier (~48:08) and don't do it justice. The main feature that sets it apart from other conductive pens is it's extremely quick dry time. It is ready to go within 60s after drawing...

    Apart from that, Great Job! :)
