Important changes in master controller software

I have just rolled out an important software update, that includes some cool new features:

  • Huey head support added
  • Single throttle MKIII collective support added (all spring-loaded switches so far)
  • fast EMA filtering added for cyclic and pedals
  • ADS1115 sample rate reduced for absolute smoothness of controls

Addition of support for single MKIII collective lever along with the Huey-style head means that most of MKIII users can now try upgrading to MKIV version! And the latter two features is why they probably should.

The idea of EMA filtering and sample rate reduction was offered by our DIY community member, Pablo Castro, quite a while ago. Sadly I could only try it today, and results turned out to be great! While controls were already very smooth, now they are even more precise, yet filtering doesn’t add noticeable input lag.

Thanks, Pablo!

Note that for the new version to compile, you will need to remove old ADS1115 library from your IDE and install the new one from z_libraries folder in simchair4_software repo. That library is a fork by soligen2010 that allows ADS sample rate tuning.

If you are upgrading from MKIII version, please don’t forget to select your devices in device_definitions tab manually.

Stackable throttle quadrant MKIV

Here’s the MKIV stackable quadrant, the helicopter edition!

If you fly twin-engine stuff like MI-8, BK-117, etc – and also want to be able to fly warbirds sometimes – you’ll like the new quadrant!

The current, helicopter themed, version supports 2 axes with detents (for things like WEP and reverse in planes, implemented as button presses, because why not) – but you can stack as many of axis modules as you want. The default “GA” version that will soon be available will include 3 axes and trimmers.

This version is much more thought out than the MKIII one – so the latter will be outdated with its release. Each lever is equipped with a spring-loaded pull handle that allows movement past tactile detents on both ends of each axis and provides friction at the same time. Lever caps are fixed with screws – so you can change them to whatever design you like.

The first helicopter-themed version will come with spherical caps and no trimmers. I have just added support for it to the software.

MKIV collective base is released!

I am glad to announce the completion of the 1st manual of Simchair MKIV line. The new line of hardware will take a Linux-like approach – we will have separate compatible modules that can be connected together to form a lever of choice.

The new base is epic, so from now on, the MKIII one is obsolete =) It is fully compatible with all MKIII lever bodies, and you can safely use it with those if you’re building the lever right now.

The first lever body to be released will be the compact collective – a motion-platform ready compact solution with integrated head. An interesting thing about it is that it supports the pneumatic mod, but does not require it! Also, it doesn’t need the counterweight, and that’s important with all lateral loads and shake that can be present when using the lever with motion platforms.

STL’s and sources can be downloaded from the new simchair4_models repo.
