40SPU-1 drive system
signal processor unit card - now available |

New Mini
Motion
Platform |
JUNE 09 -
Details of the new 40SPU-1
servo drive signal processor unit released..... this
ready-built card is available to buy NOW.
JUNE 09 - I've
added a beta Motion Platform Power
Calculator add-on for the motion driver software - should
help with those tricky actuator power calcs.
This
section of the Built For Fun site describes a few
projects that are quite a bit different from the electric vehicle projects available on the
rest of the site. I've
had a go at designing and building a number of DIY
flight simulator motion platforms (or motion bases) and
had a look at a few other flight sim projects such as control
loading (force feedback) and a new technique of motion
enhancement using visual display cueing.
Click on the links below for details of the
projects.
Details are now available for a ready-built PCB to
replace the home built signal processor unit electronics used in
the early servo drive designs. The 40SPU-1 card replaces all the
fiddly DIY breadboard wiring with a simple ready to connect card.
Wiring
diagrams and flash programs are also available for the
DIY electronics hardware I first used to control the platforms - see the
Control System & Wiring pages.

BFF MOTION
DRIVE SOFTWARE
Essential
drive software for DIY motion platforms - very
low cost and packed with features.
V2.4 now
available with the new integrated
virtual oscilloscope and power calculator add-on. |
MOTION
SYSTEM DRIVE HARDWARE
Low cost servo
control hardware for DIY motion platform
builders is now available. Developed from several platform builds this hardware is fully
integrated with the BFF Motion Driver software -
for 2/3 DOF DIY motion platforms. |
|
 PLATFORM
2
A more
conventional motion platform - less movement
range than Cockpit 1 but easier and cheaper to
build - FREE plans now available on the web
pages. |
MINI PLATFORM 3
The most recent platform
design, reduced motion range but easier to build - probably
my favourite and well suited for use with the new
Articulated Projector System. |
|
COCKPIT
1
The first motion
platform project - a compact cockpit with
large pitch, roll and heave movement ranges.
This was an interesting but fairly complex build
- too complex to release a set of plans.
|
 DIY
LINEAR ACTUATOR
A cheaper alternative to
expensive bought linear actuators - plans bundled with
Motion Driver orders. |
|
 DIY
FORCE FEEDBACK FLIGHT YOKE
A fascinating
project to develop an effective DIY control
loading flight yoke for simmers. Not quite right
yet, but interesting reading. |
MOTION
PLATFORM POWER CALCULATOR
Beta software
for estimating the power rating requirements on
conventional design 2 & 3 DOF platforms - should
be a great help during platform design stages. |
|
EARLIER DIY SERVO
DRIVE HARDWARE
Simple low cost
DIY servo drive hardware I've used to drive the
motion platforms. Built using PICAXE 28X1
microcontroller chips and MD03 speed
controllers. |
ENHANCED SPEED
DIY Drive Hardware
Running at 115200
Baud provides faster comms and smoother motor
drive - essential for good motion cues.
Also work done
on an even faster
High-Speed servo control. |
LOW NOISE
POSITION FEEDBACK
To get the best
out of a platform drive low noise position
feedback is important - how I got on with US
Digital MA3 Encoders. |
|
|
 ARTICULATED
PROJECTOR
A new motion
enhancement for DIY platforms and sim setups -
have a look! Free construction drawings
available. |
DIY
FORCE FEEDBACK
Some interesting
experiments with a DIY Control Loading system.
Still needs development but some interesting
reading. |
IMPORTANT - Building a DIY motion platform
is a big project, even for competent DIY'ers. It
involves knowledge of both mechanical and
electrical/electronic systems, it can be expensive and
it can be dangerous to both people and equipment. The

"AS-IS" without warranty or guarantee of any kind and is
provided in good faith to assist other builders in their
efforts. The information does not include complete and
detailed instructions on system building, commissioning
or operation. If you chose to use this information in
your project you do so at your own risk - it is up to
you to properly understand what you attempt to build.
