Cantilever Wooden Sim Racing Rig

Cantilever Wooden Sim Racing Rig

Sim rigs can be very big and ugly, which means they aren’t very suitable for the family living room.  I finally made time to build one that looks like an interesting piece of furniture, with high wife acceptance.  I’m using an Oculus Rift CV1, and this minimal rig is perfect with it.  The steering wheel is very comfortable, the wooden pedals are warm and feel great on the feet, and the S2000 seat is very supportive.

Wooden Cube Gaming PC Case for matx

Wooden Cube Gaming PC Case for matx

I wanted to build a new gaming PC to go with my OSW Direct drive wheel, custom hydraulic load cell pedals, and Oculus Rift CV1.  VR is the best thing to happen to gaming in years, it is revolutionary for driving games.  The requirements were for a full size gaming card, mini or matx motherboard, standard intel CPU cooler, ssd hard drive.  I had no requirement for an optical drive.   Continue reading “Wooden Cube Gaming PC Case for matx”

DIY GT3 style wooden wheel for OSW Direct Drive

DIY GT3 style wooden wheel for OSW Direct Drive

If you want an inexpensive wheel adaptor for your direct drive force feedback setup, you can make a very simple and effective clamp from timber.  A split wooden clamp with one bolt works very well, and it is absolutely solid, with zero slippage.   You need to be careful to drill and sand the centre hole of the clamp to be just the right size for a snug fit on the motor shaft, and the clamp will hold it solid.  I would recommend an accurate drill bit, like the Irwin Speedmax.  Standard spade drill bits don’t tend to make a nice round hole.  I used a slightly smaller diameter drill than the motor shaft, and sanded it bigger for a snug fit.

Adding buttons to an OSW with the MCP23S17 serial chip

Adding buttons to an OSW with the MCP23S17 serial chip

I replaced my g27 pedals with a custom setup, and I also use a custom sequential shifter and handbrake.  I’m running a direct drive OpenSimWheel, which is brilliant, and the G27 shifter is currently connected to it for shifting/button purposes.  I wanted to remove the G27 shifter, which contains a serial interface chip which converts approximately 16 buttons into just 5 wires connected to the Disco USB controller.  On the OpenSimWheel with MMOS firmware, you can connect buttons directly to the STM32F4-Discovery controller board, but you would need one wire for each button which isn’t practical.  A serial converter board connected to the Discovery controller would allow me to remove the G27 shifter, and still connect the sequential shifter and e-brake.  Of course, you could have a separate USB controller, but I like having it all run through the Discovery in my OSW.

Custom Hydraulic + Load Cell Sim Racing Pedals

Custom Hydraulic + Load Cell Sim Racing Pedals

The OpenSimWheel direct drive steering wheel I built recently has completely outclassed the Logitech G27 pedals and shifter, so I’ve decided to upgrade my pedals.  I’m after hydraulic pedal feel, smooth action, long pedal arms, and a more realistic progressive brake pedal.  I’d like some Heusinkveld Ultimate pedals, but they’re out of my price range.  So I built some pedals with similar features and layout, out of recycled timber.

Dirt Rally 0.6 Update unofficially supports Direct Drive (OSW) Wheels

Dirt Rally 0.6 Update unofficially supports Direct Drive (OSW) Wheels

Dirt Rally is shaping up to being a solid rally sim, which is pretty exciting considering there haven’t been any good rally sims released in about 10 years.  I was enjoying it with my old G27, but when I moved to an OSW I soon discovered that the game only supported a fixed list of popular steering wheels.  Almost every other driving game allows any direct input compliant steering wheel to be used, except Codemasters titles.  Perhaps they could rewrite their controller setup UI to be something versatile like the menus in iRacing or Assetto Corsa.

Fixing a Digitech QM1323 multimeter with an intermittent fault

My trusty Digitech QM1323 multimeter hasn’t been so reliable recently. It has been flaky with its readings, and I thought it might be faulty connections where the leads plug into the multimeter.  Resistance and voltage readings seemed like they only worked sometimes, and I was always pushing or turning the leads where they plugged in.
