As I have mentioned in previous posts to other discussion threads, I'm designing and building circuits to adapt the K100 electrics to aftermarket gauges.

Gear Indicator and Start Enable Board

The TGPI design has gone through a few iterations, with the current version 4.1 being based on a micro-sized Arduino processor.  This design is adaptable because of the on-board computer and can display the gear in a multiple of ways:

  • With a numeric digit using a 7-segment 0.39" LED display[/li]
  • With up to 6 LEDs, each LED representing a selected gear[/li]
  • With a direct connection to an aftermarket Koso gauge which has inputs for displaying a selected gear[/li]
  • With up to 6 incandescent bulbs, similar to the LEDs, but for a retro look when placed behind a bezel[/li]

As shown in the photo below, there is a separate 7-segment display board with a cable length of 150mm, however a custom length can be provided if required..  The intention with such a short cable is that the board and display will be together in an enclosure.  It is possible that this arrangement does not meet with your intended design.  When ordering, I will exchange information with you to understand how and where the board will get use.  This allows me to tailor the display umbilical cable to a length that suits your build.

The Gear Indicator and Start Enable Board also has circuitry to amplify and condition the speed signal coming off the rear drive. Many modern aftermarket speedometers require the use of an active inductive sensor that outputs large voltage levels (>7 volts) for the meter to work properly.  This usually means adding a magnet and aftermarket sensor to the front wheel to get that signal.  The variable reluctance (VR) sensor in the final drive of the K100 is not capable of reproducing these active signals without help.  The circuit on this board will amplify the weak VR signal from the K100 sensor, making it usable for a range of aftermarket speedometers.  This means one can re-purpose the OEM sensor and avoid adding additional sensors to the bike..  This feature means that you don't have to use the manufacturer's speed sensor and worry about finding a place to mount it.

I have developed the next version of the TGPI board (v5.2).  This version includes new functionality and a fundamental change in the design.  There is a circuit now that will condition the engine RPM signal available on the Black/Blue wire (Pin 16) of the OEM cluster, and make the signal compatible with aftermarket tachometers.  I have also included a more robust power supply onboard along with a resettable fuse and transient voltage protection.  This will result in a more robust reliable board than previous designs. Finally I have integrated a circuit on the tachometer output that adjusts the signal to make it compatible with one particularly popular Chinese aftermarket gauge.

Aftermarket Gear indicator/Neutral indicator board & 3-circuit Fuse block 2qsz3vb

The overall size of the board is 4cm X 6cm.

The change in design with v5 means that I manufacture the board based on the type of display you desire.  There are two versions of the build and unfortunately, they are not interchangeable between themselves.  That means we collaborate during the ordering process to make sure I supply you with the correct version of the board.

The tested board and LED display is targeted at $75.00 CDN plus shipping.

TGPI User's Manual Online

Speed and Tachometer Conditioning Circuitry:

If all you're interested in is just the speedometer amplifier circuitry or just the tachometer conditioning circuitry or both, it is possible for me to build only that function on the board and largely ignore the rest of the components.  The cost is significantly reduced, down to $25.00 CDN plus postage, for that board.

3 Circuit Switched Fuseblock

Aftermarket Gear indicator/Neutral indicator board & 3-circuit Fuse block 20130424-acc-fuse-003
This board provides three switched 12 volt fused circuits in a compact 5cm X 5cm package for powering accessories that you add to your bike.  The switching relay is provided on the card, which simplifies the installation.  These circuits can handle up to 30A current total (the limit on the switching relay's contacts) and has a LED for power indication.  The tested board is $21.00 CDN plus shipping.

The prices are very close to my costs just for the parts that are used.  I'm making no money on these, but making them available to support the community of K-bike owners.

4-Relay Neutral Detect:  

I have designed a printed circuit board to simplify the construction of the popular neutral detect circuit using four relays.  The board using through hole components which should be easy to source locally in a number of markets.  I was thinking of supplying this design in a flexible way, to meet different budgets and skill levels.

  • A completely assembled and tested circuit (first photo)[/li]
  • A kit consisting of the PCB and all parts ready to be assembled (second photo)[/li]
  • The raw PCB[/li]

The board overall is 5cm X 5.2cm in size. It will take input from the TGPI switch and output a Start Enable signal and an active-low Neutral signal whenever the transmission is in neutral position.

Great work Rob, can't believe those prices! This post should be first port of call for any one going aftermarket speedo route, it would save lots of banter when guys post asking how to get them to work. Can the forum somehow highlight this since there are many posts on the subject?

Love your work and the way you freely share your Knowledge, well done.

very nice solution rob

and the switched and fused board is great as well ...

prices are great

well done ..... 
 
I would think that you have a few sales immediately and could become the "end all the drama issues that many perceive as problems for an upgrade " reference

I would be thinking world wide sales will follow real quick, once the word gets out

if I could suggest ....you need to mark it up a bit in price for the "non afflicted kpox addicts "   grin



ps. I know of a few other places to advertise this solution if you are ready for a flood of enquiries

I do suggest that a good "connect up for dummies " be included
along with a disclaimer for faulty gpi  switch applications

question though ...did you include some bleed voltage to the gpi switch ( for wetting the  contacts ) ...not obvious immediately...oops found them ...woohoo



great project

cheers !!!!

Hi Rob

You can count me in for one of the gear displays as I'm (very) slowly gathering parts for a brick trike for my wife. I guess the question is:

Shipping to Northern Ireland?
How to pay you?

I'd prefer the indicator and the board to be unconnected (i.e. no wires) as that will give me maximum flexibility when designing the wiring loom. A connection diagram would be great help though Smile

I have a problem.

I linked the photo and thread to Kiwi Biker forums and theres a lot of people wanting your boards now.

Im wondering if we might need sort out a shared freight deal to New Zealand.

You could join Kiwi Biker Forum and advertise them if you like.

I think this is a a good idea Mossy.  I was checking postage today and I can send four boards to New Zealand or Australia for the same price as one board.  It makes much more sense to aggregate shipments to distant (relative to Canada) continents and distribute locally.

Can you PM me the link to the forum thread? I searched on Kiwi Bikers but failed to find the thread.

just a suggestion ...nip up to jaycar and get some "protective circuit board lacquer"   and coat both sides if you haven't already done so

The suggestion of applying a protective coat of lacquer to the circuit board got me thinking (wondering?).  The displays deteriorate with age.  Could painting them with lacquer prevent/retard this? 
I don't really understand why they die.  They are well protected inside the instrument housing, yet they seem to die in bits, as if they've been struck with something.  What's happening to them?

brickrider,

If you're talking about the K-bike's standard gear display, it is liquid crystal and not Light Emitting Diodes.  Earlier generation Liquid crystal displays do deteriorate as they age, and the displays begin to fail.  It can't be stopped by applying lacquer or other UV protective coating to the display because the cause is with the aging of nematic crystals within the display.  I understand that the liquid crystal polymers age and fail to align properly when voltage is applied.  Thus they no longer polarize light properly and the segments disappear.

If you're talking LEDs, they tend to catastrophically fail, just like a light bulb.

Yes, I was thinking of the gear display.  I'd overlooked the obvious - that a LED and liquid crystal display are like apples to oranges.  If I understand correctly, the crystals will fail with age, no matter how they're treated e.g. exposure to sunlight, temp. swings and what not.

I have a new design which has an on-board computer rather than using a hardware based chipset.  The new circuit boards are on their way from the manufacturer overseas so might take a little time.  I'll have 10 boards ready as soon as I received the cards and build the circuits.  The total cost will be higher because of the different components being used.

Hi,

I'll have to start building a list of potential clients, it seems.

The board will work alongside your Acewell, providing dash functions that it does not provide. The unit is not quite plug and play. Wires in the harness will have to be cut and routed to the board. New wires will have to be installed to bring outputs to new dash indicators. This requires some level of design and installation.

@robmack - For the neutral detect, have you considered instead of the relay board, producing a small pcb utilizing the Logic Gate and Driver transistors? 
I think that could be popular option with users 
Shouldn't need the power supply as that chip will run off 12V 

Thanks for everything you contribute to this site and the community!

I have not considered a design that replaces relays with solid state components. My motivation in designing it and offering it to the K100 community was that it was simple to understand and easy for a modestly skilled person to assemble, if they so chose. This relay circuit of mine is the least popular and I can count the number of units sold on less than the fingers of one hand. Although a transistor / IC based unit is tempting, I can't see much interest in the K100 community for one.
