focus - take charge

  • CES, V3 and More - 19th January Update

    It's been a busy few months at foc.us towers. Here is a quick update of what's happening.

    The successor to the massively popular V2, the V3 is now available to buy.

    We're very excited because it includes a new type of stimulation invented here at foc.us studios - tRCS - Rippled Current.

    What is rippled current? It's a dynamic-time frequncy designed to increase peak alpha brainwaves. Read more here.

    tRCS is only available from the focus V3 (coming soon to EEG Dev Kit) so order here to get your alpha vision.

    Talking of brainwaves, the EEG Only Dev Kit is now in stock for next day shipping. All 2nd batch EEG orders will ship by the end of January.

    Go Flow Sports orders will also ship shortly, small delay with inbound stock from China.

    Lastly, CES was great fun. Thanks to everyone who said hello. See you again next year!

  • EEG Dev Kit Update December 28th

    tl:dr; EEG Dev Kit production completed. Electrodes almost finished. Orders shipping soon.

    Manufacturing electronic products can be difficult.

    Making 10 is easy - they can be done by hand. Making 10k is easy, everything is on reels direct from the supplier.

    But making 100 or 300 or 1k is where the dragons be.

    Big manufacturers don't want small orders like this. Components are not sourced on reels so must be checked individually. Setup time and overhead fees are disproportionate. Everything is a PITA. This is what foc.us fights with.

    But today's story has a happy ending.

    Our new PCBA factory is much bigger than the two we have used before:

    They use the same pick and place machines:

    But the quality control is WAY better as they x-ray every PCB one by one.

    The EEG Dev Kit has nine BGA components so this step is crucial in identifying any possible problems.

    This has resulted in the best yields we've ever seen - 99%!

    The cost of EEG components is crazy high, so a yield of 1% (it's actually less than 1%, I rounded up) is fantastic news for us.

    Each Dev Kit includes three pcbs - main, sockets and electrodes. This is the sockets PCB exiting the oven.

    All that remains to complete is the new EEG+ electrodes. They are nearly done and will be very soon.

    We will be using this factory for all PCB work henceforth. If they can get 99% yield for EEG we expect 110% for Go Flow ;)

  • Our $50k Mistake - EEG DK2 Update Dec 7th

    First the good news - tDCS functionality is now available in foc.us/me and the 2nd production run of foc.us EEG Dev Kit resumes next week including a new EEG electrode design.

    The bad news (for us) is that our original EEG electrode design had a small design fault.

    If you need help with initial setup please schedule a call here

    Don't miss the chance to be part of 2nd batch family here.

  • EEG Dev Kit September 5th Update

    tldr; EEG Dev Kit orders will ship this week.

    People say "hardware is hard" and they are right. But software is much, much harder.

  • EEG Dev Kit Update : Cutting Time

    This update is over-due but we've been making some hard decisions which has delayed us.

    We are way too late in shipping these out to you. We have not finished the firmware. The delay is caused by finishing the firmware. The firmware has been nearly there but not, for months.

  • Bran Stimulation

  • Focus Turns 4!

    On this day four years ago we shipped the first commercial tDCS brain stimulator - the foc.us Gamer.

    Three years ago we added every bell and whistle to bring you the foc.us v2.

    Last year we went back to basics with pure tDCS for the easy to use Go Flow stimulator.

    Next week we turn a new page. We will start shipping our most important product yet, the foc.us EEG Dev Kit.

    The addition of EEG functionality marks a step towards smart stimulation.

    What is smart stimulation?

    Smart stimulation is personalised, dynamic, and guided by feedback. Using data from EEG fed through machine learning algorithms,

    It will take some time to get smart stimulation but that is our goal.

    We would not have got here without your support. Your feedback, requests and orders drive us forward.

    Forward towards closed loop stimulation, AI enabled protocols; the future of brain stimulation.

    Thank you!
