Shipping restrictions for some countries

I get a lot of questions recently if ordering is still safe in times of the Coronavirus. The answer is yes. You can still order and I can ship your order, except for orders from most African and South American countries. If you’re not sure you can contact me via email to get up-to-date information on your country or check the list of restricted countries here (CSV File written in German language).

As a precautionary measure, non-EU orders are being shipped as registered priority mails (with tracking number). Customers from EU countries now have a choice between unregistered shipping (Priority) and registered shipping (Registered Priority). Your order will be delivered by your country’s postal operator.

I observe the situation daily and update this post as soon as something changes. (Last updated in April 2021)

Powering Elektron Devices From Portable USB Batteries

Elektron is a Swedish brand of very popular electronic musical instruments, such as drum machines, samplers, and synthesizers. Most of their devices run on 12-Volt DC and they come with a power supply unit that is connected to a socket. The question is: Is it possible to power Elektron devices grid-independently?

The short answer is yes, there are various ways to accomplish this. The most practical and affordable way is to use portable smartphone chargers, also called USB power banks or USB portable batteries. Thanks to the huge smartphone market and the USB charging standard you can get good USB power banks for little money.

How to power Elektron devices from portable USB power banks?

As you might know, the output voltage of these portable USB batteries is 5-Volt, but Elektron devices need to be supplied with 12-Volt. That’s where my 12V-Birdcord comes into play. It’s basically a voltage converter that converts 5-Volt from USB-ports to 12-Volt for audio devices, but it’s actually much more: The Birdcord’s built-in soft-start circuit prevents power banks from shutting down due to the high start-up currents of some audio devices. This makes it the only voltage converter that can power bigger audio devices like Elektron devices from USB power banks. Also, Birdcords work completely noise-free. Many musicians love to use it in the studio for this reason.

Important additional info:

  • You will also need a 2.5mm adapter to run your 12V Elektron device with a 12V-Birdcord.
  • The maximum output power of the Birdcord is 9 Watts. For permanent use, I recommend not exceeding 7 Watts to still have some margin and to not overheat the Birdcord and the USB power bank.
  • These Elektron devices can be powered via Birdcord: Elektron Digitakt, Elektron Digitone, Elektron Octatrack MKII, Elektron Analog Drive
  • These Elektron devices can’t be powered via Birdcord (yet): Elektron Digitone Keys, Elektron Model:Samples, Elektron Analog Rytm MKII, Elektron Analog Four MKII, Elektron Analog Heat MKII
  • The rated output current of your portable USB battery should be 2.1A or higher.

Birdcord: New Packaging and Technical Upgrade

Almost one year ago the Birdcord USB→9V Converter Cable has been released and as you can imagine I learned a lot of things and got a lot of feedback from you since then. I now integrated these lessons into the Birdcord to offer you an even better product.

New Packaging: It turned out that the acryl box is very unpracticable because it’s hard to put the cable back in (too small). I now replaced it with a beautiful drawstring pouch with the Birdcord logo on it.

Cable Length: Due to popular demand I changed the cable length from 50cm (19.7″) to 55cm (21.7″).

Soft Start: Powering bigger devices like the Boss RC505 or RC300 Loopstations or the Digitech Trio+ from USB power banks has been a problem before because these devices need a very high initial current/startup current. Even though the Birdcord could handle this current the power banks would shut down. Not anymore! I now integrated a soft start circuit into the Birdcord that allows starting up these devices without overloading the power bank. It works with any USB power bank with an output current of 2A or higher (small devices still work from any USB port of course).

More Output Current: The new revision of the Birdcord is capable of a maximum output current of 1000mA@9V. Having said that I still recommend not drawing more than 700mA for permanent use to have some margin left for short current peaks and to ensure a long life of the Birdcord and your USB power bank.

Thank you all for your support 🙂

P.S. I didn’t update the product pictures in the webshop yet because I’m going to release new voltage versions of the Birdcord very soon and will combine the photoshoot for all the different versions.

Great Reception Of The Birdcord | Product Of The Year

It has been about 7 months now since the release of the Birdcord USB to 9V Converter Cable and many musicians around the world already got one. Most use it to power their pedalboard, but there are also some who use it for powering synthesizers, drum machines, portable amplifiers and more. The feedback that I get is extremely positive. More than half of the sales come from recommendations. Thanks to everybody who bought a Birdcord, to everybody who provides me with feedback and product wishes and of course thanks to everybody who spreads the word online and offline, you are amazing!

Here’s an extract of the online reception of the Birdcord:


New Opto Tremolo In Development

After countless modifications and testing more than a dozen of different resistive optoisolators I am finally at a point, where my new Vactrol-based opto tremolo circuit sounds just awesome. I already sent a first prototype to Styrian guitar player “Sir” Oliver Mally, who confirmed my assessment: this is something big. I’m really looking forward to bringing this little sound monster to market in the next weeks!
