New ATOMI servo & stepper drive boards are here!

Tero — Fri, 18 Nov 2016 15:35:27 +0000

Earlier announced ATOMI is finally getting the focus it deserves! Now we have second revision boards under our scope for testing and firmware development. From initial tests, we can tell that we’re very close to the final design. At the moment it looks like we need only to change one resistor value on the PCB to make it final.

We can thank Esa Hippolin from the beautiful hardware design.

Simulator wireless magnetic paddle shifters and buttons

Tero — Fri, 05 Aug 2016 13:27:13 +0000

It’s time to make another post about amazing work of Juha. Now he has completed his design of magnetic paddle shifters as well as wireless transceiver. A group of us did test drive of the wheel and everyone immediately fell in love with the snappy feeling of magnetic shifters.

The magnetic switch has a micro switch and a small permanent magnet to produce the “spring” force of the paddle.

Maybe best of all, it’s open design. 3D printable parts and other info can be found from this Thingiverse page.

Simulator rig

Tero — Sat, 02 Jul 2016 12:17:43 +0000

We asked couple of friends to help assembling the SimuCUBEs of the Indiegogo campaign, and as reward from their help I gave them SimuCUBEs. Well, this is what happens when you give them to brilliant people:

Simulator rig frame where the seat, steering wheel, pedals and SimuCUBE will be installed

Cutting simulator rig plywood parts with CNC router

This is a project of Juha which has been inspired by the earlier build of another help contributor, Mika. More updates will follow!

SimuCUBE final hardware has just born

Tero — Mon, 02 May 2016 16:35:57 +0000

Today we received the first samples of final SimuCUBE board designs. Testing of it shows no flaws so we’re giving the green light for the first 250 pcs batch assembly! All parts are already in stock, so assembly should not take too many days.

The photo above shows also the work-in-progress test bed for SimuCUBE that will be used to test & verify the operation of every shipped SimuCUBE. The device under test will be placed on the top of the bed and the spring loaded pins will contact certain pads on the bottom of the SimuCUBE board to allow tester to contact all necessary signals at once.

Prototypes of SimuCUBE motherboards and acrylic case have just arrived! The first successful test drive has been done with a big smile :) We hope to have Indiegogo campaign launched on the next week. Get ready for early bird specials!

SimuCUBE – the force feedback controller from the future announced

Tero — Tue, 09 Feb 2016 11:36:06 +0000

I’m happy to reveal the details of the upcoming force feedback controller – SimuCUBE! The hardware design is now complete for prototyping and we will get prototypes in the lab in the next month. SimuCUBE has a STM32F4 microcontroller that is compatible to a popular STM32F4 Discovery board. The plan is to start an open source firmware project for this board.

SimuCUBE will change the way simulators are built. Click to enlarge.

Brilliant hardware design & image render by Aki.

ATOMI – the ultimate 4 axis CNC controller

Tero — Tue, 26 Jan 2016 11:01:39 +0000

We’re proud to announce ATOMI, the revolutionary multi axis drive for CNC applications. It is a closed loop stepper drive that essentially turns stepping motors into servo motors. ATOMI gives the benefits of both worlds: reliability of servos and high torque of steppers.

ATOMI age is coming

ATOMI will be launched in the Indiegogo on Q2/2016. Stay tuned and grab the early bird specials!

Ps. it is largely based on IONI technology. IONI Pro will get all the same features than ATOMI through firmware upgrades.

Peak power limit feature is coming

Tero — Tue, 19 Jan 2016 13:17:16 +0000

Today’s development on IONI Pro has revolved around the development of feature called Peak power limit. With that, user can set the exact amount of Watts that drive is allowed to transfer from PSU to motor.

This may be useful when using drive from a switch mode power supplies that normally shut down on overload condition. With this parameter, one can set exact amount of power that is available from PSU to prevent overloads. This also helps to save money on power supply as there is less need oversize the PSU in order to handle the highest load peaks.
