A little bit old but a nice project to increase the movement of the Rock'n'Ride chair. This is a special designed USB interface to control all eight valves of a 2DOF pneumatic valve isle. The difference to the standard rock'n'ride interface is a speed controlled movement with short pulsed air throughput. With a special designed open and close sequence it is possible to move the pneumatic cylinder slowly without breaks and micro stops. This will increase the positioning of the old interface from 7 positions per axis to more positions and a smoother movement. Compared to a electrical solution it is of course not good enough.
What you get:
- 2DOF control of a 8 pneumatic valve isle (based and similar to the Rock'n'Ride chair)
- pulse mode valve control for speed control without a analogue pneumatic valve
- plugin support for X-Sim with automatic detection
You will need this things:
- knowlege about how to edge this board
- knowlege for soldering, especially the SMD parts
- the old linear slider pots of your normal serial port Rock'n'Ride interface or similar pots for your simulator
- a 8 pneumatic valve isle or a similar connected isle from another distributor with 12-24V as power supply
- all the electric parts of the attached component list
- a pic programmer like described below (also has to be edged and builded)
The valve isle of the Rock'n'Ride:
PIC programmer:
You need to upload the attached firmware hex file to the PIC microcontroller. You can use this options:
DIY Solutions:
- http://perso.wanadoo.fr/softelec/Projec ... aer_us.htm
- http://www.propic2.com/Download.htm (Software = Shareware / Hardware=Free+ICProg=Free)
Programmer software:

Or you use the ready builded solution with a PIC starter kit:
http://www.michrochip.com
Or you use a local programming service:

Find the correct PIC microchip:
You will have to buy a Pic 16C745 which you can buy here:
- http://www.farnell.de (only with a company)
- http://www.segor.de (private persons but expensive)
- http://www.ek-p.de/electronics/pservice.htm (nur -JW)
- http://www.mercateo.com/ (sowas wie Ebay für Privat-Elektronik)
- http://www.rsonline.de/
- http://www.sander-electronic.de/orderform/contr4.txt (bzw. http://www.sander-electronic.de/)
- http://www.elpro.org/mainframe/mainframe.htm (cheap JW-variant)
- or of course: http://www.microchip.com as sample ??
The chip is available as a PROM version which you can only write one time and as a development UV erasable chip (like EPROMS).
If you buy a chip with - jw ending you can get a eraseable version for ultraviolet eraser. Normally you buy one or more with the ending -p(x) in a plastik housing without a erase window. If you choose the erasable UV version you need of course an fitting UV eraser.
USB cable:
On the 3-5m usb cable you have to cut and remove the B-side and you have to directly solder the cable to the board.
The left over connector is therefore:
The connection to the board is as follows: (see the layout picture above because it is mirrored):
Top = Black (GND)
Middle = white
bottom = green
Some cables do switch green and white if they are not USB certified, simple switch the if the programmed chip is not detected.
And here is a 1:1 layout to edge, the part list and the firmware hex file.

You will need a programing service company to get the firmware on the PIC Chip or you build your own PIC Programmer.
I offer for a donation of 10 Euro this service in germany.
