eyeR MOD for the Fusion Brain, add PWM, Servo and remote control. **Discontinued**

UPDATED 06-FEB-09
-- Check here for regular updates --

The eyeR Interceptor for the V3 Fusion Brain has now been discontinued! The new model will now support the Fusion Brain V3 & V4.

Click HERE for the link to the NEW model. :)

Initally this thread was going to be updated with the new model, since the V3 version is still going to be supported Im going to leave this as is.

eyeR For V3 Fusion Brain STATUS:
**Discontinued**

OK, so whats the big deal of an eyeR Interceptor Piggy-backed onto a V3 Fusion Brain? ...
The initial idea of the eyeR was to be able to control your original FB outputs even when the PC is off, still booting or failed. This device has now matured to much more than that:

• 20 Relay high current outputs
• 10 Analog Inputs
• 4 Digital Inputs
• 5 low signal Inputs/Outputs (some are multiplexed for Servo and PWM)
• Drive-by-wire Bus connection (this allow countless devices to be daisy chained)
• Automotive transient suppressor, that protects the FB and eyeR from glitches
• Corrects the Fusion Brain LED and output mismatch
• Remote control override of the FB outputs or the HVAC Features (even when PC is off!)
• Highly sensitive on-board InfraRed receiver (more than 15+ meters)
• External InfraRed connection (if the on-board is not enough!)
• 2x PWM dedicated outputs for controlling high powered motors, lamps and solenoids. High current devices will require optional FET driver. (PWM controlled on-board for operation even when FB is disconnected)
• Built-In highly advanced progressive servo controller/driver. The speed and range of Servo movement can be precisely adjusted!!
• Servo can independently be powered down to eliminate servo *squealing* at high loads
• All eyeR features can be controlled without the eyeR Micro-USB cable connected.
• Fusion brain will not suffer in performance and functionality (eyeR uses an intelligent addressing system to make the Fusion Brain talk to the eyeR without the Brain knowing)
• Has its own set of 12 LED outputs to show you the true state of the Fusion Brain intercepted outputs
• External RS232 low level outputs for direct connection to other non-PC micro projects
• Firmware updates uploaded via USB

Some uses:
1. Say you have the eyeR as a HVAC replacement for your vehicle and its cold and foggy, and for some reason the PC turns off or your screen goes blank? How are you going to demist those windows?
With the eyeR optional remote, all the HVAC features can be controlled via the IR slim remote (even when FB unplugged) while still allowing these features to be controlled via PC.

2. So your Fusion Brain is in a stable state, and you need to turn off an output for some testing but the PC is not within reach? You can use the IR remote to override the outputs.

This plug-in MOD is powered from the FB so no additional supply is required.

Fusion Brain and eyeR COMBO. Its not simply just sitting on the Fusion Brain for looks, its actually plugged into the two driver IC sockets on the FB.

eyeR Actual size 33x45mm.

Basically the eyeR processes (intercepts) the signals of the Fusion Brain CPU outputs before they reach the output terminals.

Using the modified FBDemo software you will see from a few clicks how easy it is to use VB to control the eyeR (Thats because the eyeR does most of the hard work!)

[CENTER]**FBDemo has been updated to support latest winUSB drivers
Here is the screenshot. Look out small monitors the actual window size when running is 1000 x 850 (At least it shows you everything clearly)

**Must thank mx270a for his work on the original FBDemo software.

I'm liking this. I might have to wait to get one but I have it on my list and will be adding one to my FB. Very nice work.

If this does PWM, then it suggests that you could connect up all the engine sensors in your car and output PWM to the car's ECU for reprogramming AS YOU DRIVE; live remapping for fuel effiency, power output, turbo control or similar.

If this combo has that potential, that's incredible!

If your thinking of replacing your entire ECU with the FB and eyeR combo, i'm afraid there is alot more needed to do that, for instance:
- Frequency inputs.
- Fast sampling of analog inputs.
- lots of interface componets.
- Firmware of the controller on the board would have to be 100% dedicated to processing the engine management.
- it would not be controlled via a PC.

At this time that's not possible.

For the turbo boost controller, if you had a pressure sensor and the appropriate solenoid it would be very possible to create a boost controller. It would be simple but possible.

Haha, cool idea, but you must be crazy trying to use windows xp to any engine management. You'll need a reatime and dedicated processor for something like that.

Oh god no, not realtime (that's what megasquirt is for.) But the idea of a plug-in device that can read all the info and then remap without having to take it in and out of the workshop or to a rolling road would be very convenient. In fact, simply the idea of having something like this in your workshop (instead of paying however much for a remap every time) would be brilliant, and for what? $120? Way cheaper than professional kit

This is great news! Does the FB MDX talk to the additional relay ports? Have you talke to Sonicxtacy02 about adding the additional functionality to RRFusion? I checked you website and I assume you're only taking preorders at the moment, but as soon as RRFusion can be updated to control this addon board - I WANT ONE!

The eyeR can be controlled 100% via the Fusion Brain, you just have send data to the D0-D7 in a special way. If you have a look at the modified FBDemo source you will see.

So I've got a question about this add-on board. I want PC control on the HVAC control head also.

The mode and temperature dials have 9 and 16 positions respectively. These dials are potentiometers. So basically a variable resistor divider changing input voltage to the brain of the HVAC control head. Could a Fusion w/eyeR substitute the input voltages? For example in theory the temp selector with 16 positions inputs voltages based on 5V feed. With an effective working range of 0.1 to 4.9V you would have a .3V change with each position. So .4 - .7 - 1.0 - 1.3 - 1.6V and so on. Physical removal of the pot's center pin from the board on the HVAC control head and the Fusions circuit attached at that point.

Could the Fusion w/eyeR output these voltages on a single circuit to the HVAC control head?

When you mean 9 and 16 positions, are you saying that there are 9 and 16 markers on the dial, or do you mean 9 and 16 steps when you turn the dial?
If you feel steps when turning the dials these would be rotary encoders.

If the two dials are in fact potentiometers (variable resistors) then yes these can be easily fed into the Fusion Brain. As for sending these voltages to the outputs, you can use the eyeR outputs as multiplexed ones. You will then have to create a DAC (Digital To Analog Converter) quite easily with some resistors so you can output the correct voltages. Alternatively you could use a digital potentiometer connected to few of the outputs (this feature should be available in a while in the next software release)

So to do this you will need a *little* bit of interfacing.

So with this setup do you want to be able 1. To read the mode and temperate dial settings and display them on the screen, or 2. Do you want to read the signals, do some processing on them and then output different values.

If your wanting option 1, then you don't need to output the voltages again. You just simply tap of the center off the two dials and connect them directly to the Brain.

Though option 2 allows you to change the temp and mode using the dials OR the PC.

Initially I wanted to cater for on-board high speed A/D (Analog-to-Digital), a digital potentiometer and many other things. If I did this the board would of been allot more expensive and bigger (as you can see there is not much room left) Saying this I have added an I2C (I squared C) BUS, which allows you to connect a huge amount of external devices than are compatable with this BUS. So you only choose what you need.

You may have noticed that this is the fist mention of I2C?? well thats because I haven't added devices in the software yet.

P.S if your wondering where the connection for the I2C is, its on the underside of the board.
