      what ever happened to the android app

    2. Creator edwin himawan on April 9, 2014

      Is the bluetooth expansion board is ready for purchase yet?

    3. Creator Brett James on March 22, 2014

      Finally have some time to use it :)

      Can I confirm with the power supply included that:
      Red is active, and Black is ground?

    4. Creator Stevie on February 18, 2014

      @Frank de Haan: Ususally for the customs it is fine to show them the Kickstarter page and your account statement which shows the sum going to Kickstarter / Amazon. Worked for me in several cases.

      I still don't get my reward. Please help

      I finally picked up my Hydra parcel. I found the red Hydra and AC adapter with some cables and letter. But I did not find the Bluetooth 4.0 expansion board in the package, Please check your record for my pledge. Thank you!

    7. Creator Chris Rhoades on January 14, 2014

      Any timeline on the Android version of the software? I know BT4.0 is pretty new on Android phones but I can hope :)

    8. Creator Aragon Gouveia on December 21, 2013

      I received my Hydra recently. Happy so far - thanks a lot Caleb. My only criticism is that it would have been nice to have the electrical specifications neatly printed on the casing, as in:…

    9. Creator Gary Chang on December 19, 2013

      When could we get the app from app store?(iPhone)

    10. Creator Frank de Haan on December 6, 2013

      Hi Caleb,
      I need a invoice and a delivery note for my Hydra.
      The german customs house sent me a note because there was nothing visible on the outside of the package.
      I pledged for the Hydra with the bluetooth board and I can't wait to get my hands on it. ;-)

    11. Creator Caleb Chamberlain on November 21, 2013

      James, you will be happy to know that your Hydra is shipping tomorrow. :-D

    12. Creator James Bailey on November 20, 2013

      At least once a week I work on a project where I'm like "damnit, where's my Hydra". Hard not to be a little frustrated as it was due in April, and I just blew something up (my own stupidity) by trying to improvise a Hydra. Caleb I'm holding you accountable for letting the smoke out of my UCC37321P, may it weigh heavily on your conscience ;)

    13. Creator Caleb Chamberlain on November 19, 2013

      Thanks, Chris! The feedback is very much appreciated.

    14. Creator Chris Johnson on November 19, 2013

      I just hooked up my Hydra tonight and have to say it is pretty friggin amazing. This is one slick product you have here. I really hope this sells well for you. /thumbsup

    15. Creator Caleb Chamberlain on November 15, 2013

      Hi Larry,

      They haven't all shipped. We had some problems with enclosures and are waiting for the last batch of new enclosures to come from the anodizer. It'll definitely happen next week.

    16. Creator larry d jamner on November 15, 2013

      Hi Caleb,
      Still awaiting word on my Hydra with bluetooth expansion board(^-^) The Oct 31 update indicated all would be shipped by the following week -was that the case? Thanks in advance for your reply. Congrats on the Project. Larry

    17. Creator Tavares Ford on October 29, 2013

      Any update on the bluetooth expansion boards?

    18. Creator Caleb Chamberlain on October 14, 2013

      Our first priority is to get the rest of the preorders shipped, which means working out the kinks in the bluetooth expansion boards and finalizing the iPhone and Android software. We'll look into the OS X version of the control software after that. In the mean-time, you can access the basic functionality of the Hydra from a serial terminal.

    19. Creator TrippyLighting on October 13, 2013

      I've received my Blue Hydra and so far it looks nice. I am using a mac and attempting to use the driver and Hydra program on a VMware installation of win Vista has resulted in two BSODs.
      Is there a timeline as to when we will be able to use the Smart Power Supply Control Software natively on OSX ?

    20. Creator Robert D. Matthews on October 9, 2013

      Any update on the Bluetooth modules?

      I'd love to have my Hydra to use...

    21. Creator Caleb Chamberlain on October 7, 2013

      Glenn - I'm not familiar with KCL experiments, but note that you cannot connect the Hydra outputs in series - their grounds are tied together.

    22. Creator Mario Leone on October 5, 2013

      Hi Caleb. My black Hydra landed in my hands yesterday. I'm in Italy. I had to pay about $35 in vat and taxes. I'm VERY happy for the product. thanks. Mario

    23. Creator Glenn Lopez on October 4, 2013

      Hi Caleb.. I just started Electrical Engineering and I'm wondering if it was possible to use the Hydra for KCL experiments. I've been given the impression in my lectures that having 2 or more different voltage sources connected in series is a bad thing, perhaps I've misinterpreted the forewarning but in anycase, is there anything I need to know before I put 2 or 3 voltage sources in my circuit using the Hydra?

    24. Creator Jasper Stolte on October 4, 2013

      Hi Caleb, mine just arrived in the Netherlands. Congratulations on finishing this project, it must at times have seemed an endless journey for you.

      It's even smaller than I imagined it. Only one word applies: AWESOME!
      Look forward to using it in my next project.

    25. Creator Timothy Giles on October 4, 2013

      Caleb. Hi from Sweden, wanted to let you know mine arrived, perfect condition. 70 dollars (440SEK) of import tax (darn government). Used it for the first time today. Fantastic case, love the material, finish looks and feels bomb proof.

      The software works well, great to see the videos online. Downloaded the instructions, well written and complete.

      Good luck for the future, thanks for you and your colleagues hard work.

    26. Creator Brad on October 2, 2013

      I have now used it, and it's... BADASS! I used it for a custom photo box, I have it controlling 3 different lights, LOVE IT! PWM would of been even better though.

    27. Creator Brad on September 10, 2013

      I received mine, but haven't had time to even unpack the box, but I appreciate it and it looks great!

    28. Creator Lee R. Copp on September 5, 2013 Hydra showed up yesterday and works great. I have already put it to work powering my project: "The Phone Cop"


    29. Creator hashish on September 4, 2013

      Any one know of some low profile banana plugs that would work well with this?

    30. Creator Caleb Chamberlain on September 3, 2013

      Hi Nick,

      There will be once all the bluetooth stuff is ready (we aren't quite there yet). The bluetooth expansion board will be available for purchase from

    31. Creator Nick Kirsch on September 3, 2013


      I've already received my Hydra and it looks so cool... Unfortunately I don't have a windows box. Is there a way to just purchase the Bluetooth/Wifi module so I can use an iOS/Android device?


    32. Creator Caleb Chamberlain on August 31, 2013

      Ah, sorry. I still need to get the rest of the documentation finished. The baud rate is 14400.

    33. Creator Gui Ambros on August 31, 2013

      Thanks for such a nice product, Caleb. Just got mine, and it's working flawlessly.

      A few months ago you mentioned it'd be possible to monitor status via the serial connection. What is the speed of the connection? I tried 38400 (and everything from 9600 to 115200), 8N1, no control flow, and I only get garbage. Seems it is outputting something, but I'm not being able to read it properly.

    34. Creator Caleb Chamberlain on August 31, 2013

      Brett, we don't have any adapters for the AC-DC converters that come with the Hydra, nor do we have an alternative version that is compatible with different types of outlets and voltages. Backers with different types of outlets will need to use a converter.

    35. Creator Caleb Chamberlain on August 31, 2013

      Fabian, send me a message to change your shipping address if you haven't already.

    36. Creator Brett James on August 31, 2013

      Being an aussie, the power adaptor will not be compatible for me, without an adaptor for Australia. Are these kind of things standard? I'd prefer to slot out the US based one, and replace with the AU version, rather than a bulky international travel adapter is that is possible.

    37. Creator Fabian on August 26, 2013

      Will have a chance to change my shipping address if I recently moved?

    38. Creator Caleb Chamberlain on August 23, 2013

      Yes, definitely. I'm not completely sure on the timeline since right now we are focused on getting everything else out the door, but once we are caught up we'll be looking more seriously into it.

    39. Creator Keith Rome on August 23, 2013

      Caleb - I was wondering if you were still planning on producing a WiFi control module? I know it was tied to a $100k stretch goal, but wasn't sure if that product was still on the table as a future add-on even if you didn't reach the funding goal.

    40. Creator Caleb Chamberlain on August 21, 2013

      Thanks for pointing that out, Keith. I'll change the wording so that it is more clear. I'll also change the expected ship date to be more realistic.

    41. Creator Keith Rome on August 21, 2013

      The wording on the website would lead me to think that it does include Bluetooth. It says so twice in the description, and I don't see anything that would imply there exists a non-Bluetooth Hydra (or an add-on Bluetooth module).

      It also says (twice) that they will ship in July. The pricing appears to have been updated recently though - it shows $198 to me.

    42. Creator Caleb Chamberlain on August 21, 2013

      Hi Hashish,

      The price on our website was a pre-order price like what was on Kickstarter. In case you might feel slighted, note that the price on our website did not include shipping, so the Kickstarter preorder and the preorder from our website would have worked out to be the same.

      The Bluetooth board does NOT include bluetooth communication at the $179.00 price point.

    43. Creator hashish on August 20, 2013

      I am confused about the website description. I though the Hydra retail price was to be $200, but the website shows its $179? Also the description shows that the Hydra includes bluetooth communication under the $179 price point.

    44. Creator Caleb Chamberlain on August 12, 2013

      Hi Keith,

      Yes, very much so. We are getting very close to shipping the first pre-orders. Stay tuned!

    45. Creator Keith Rome on August 10, 2013

      With the shop hardware repaired and operational again, is there a light at the end of the tunnel now? (and not the oncoming train variety)

    46. Creator hashish on July 17, 2013

      how about an update?

    47. Creator Brad on July 5, 2013

      I'm excited for the new Case!

    48. Creator Caleb Chamberlain on June 14, 2013

      HI Glenn,

      Yes, the assembled PCBs are starting to trickle in. We received the first 16 yesterday and are in the process of testing them. They should all arrive before the end of next week if all goes well.

    49. Creator Glenn Lopez on June 13, 2013

      any updates? its been 2 weeks. almost forgot i backed this project.
