1st generation AUTO cancel TSCU "banging the bits"

[posplayr]

Been off the forum for a while... Too many things happening to mention here but was curious if this project ever got built? If not, I may go ahead and take it on for the fun of it. Been working with the Adafruit Pro Trinket for a while and it seems like a good match for this. Very compact, lots of I/O and easy to program.

That or the NANO (I have a few ebay specials) is what I would use to do a prototype.

In reality is this could be done with a 8-10 pin controller and a few protection discretes.

I'm working on a few other projects myself, including spinning another production run of the SSPB. I have been using KiCAD which is free for download and it has been dramatically improved since the last time I used it two years ago. I will be starting a new layout this week.

I've used both the Nano and Kicad and do like both. I currently have 8 or so of the Trinket Pro's laying around so that's what I was going to work with. The nice thing about the Nano is that it does have a native USB interface while the Trinket Pro does not. Adafruit did cobble together a software solution for USB download but it takes up some additional program space. The advantage of the Trinket Pro is it does have a little bit smaller footprint and does come in both 3.3V and 5.0V versions while being 98% Uno compatible sketch wise.

I guess nobody is wanting to take this on so I'll do some Tinkering (pardon the pun) and see what I can come up with. My goal would be to have a durable turn signal controller that's wire for wire compatible with the existing controller. The nice thing about doing the programming would be having complete control over the timing and speed trigger. The stock controller always shuts down on me too soon and I need to reset it before I get bellow the 9mph threshold.

As I understand it the stock control unit utilizes 7 wires. Two of which are power and ground, two are for the reed switch input, one is an output to the relay and two are inputs for cancel and start. I've seen several diagrams with errors on them in the service manuals but this is what I think is correct:

I think most of my source information came from here:

In the current board I'm doing I created several hierarchical sheets representing the 4-5 portions of the Main board I'm designing (power and signal distribution) and can then add additional sheets for external components including a mezzanine footprint for the main computer. It is a nice way to organize the design and consolidate various design documentation elements. You can even insert pictures right on the schematic which helps keep track of connectors and various other stuff. I just downloaded FreeCAD last night but that will have to wait till a little later.

Again, if you can do a PCB design, then the AT Tiny's are the obvious "production" choice as opposed to doing a mezzanine design. Of course working through the design with a NANO/Trinket on a protoboard is super simple to flesh out the S/W.

I'm assuming that you are not thinking of running wires right off this Tricket to run a TSCU without any protection?

No I wont be doing that. I'm planning on reverse voltage and over voltage protection of the power supply input using a reverse polarity protection diode inline with the power supply along with a zener diode to clamp the input to the controller at ~9V. Logic level I/O protection will basically be like this on the DIO pins:



Output driver to the relay will probably be MOSFET. Could use a simple transistor switch but I like working with MOSFETs and have a ton of them laying around. Some experimentation will have to be done to verify timing and speed control using the stock reed switch but that's what makes DIY fun.

Boy, the spam bots are hitting the forum hard this week.

[Rich82GS750TZ]

Yeah there are lots of sites spamming recently.

Not a good look for a first post my Indian friend. Let's see pictures and why don't you write something about your motorcycle, so we can see if you're a bot too.

Botfest 2023.......

[Rich82GS750TZ]

They keep on coming.
Looks like maybe Someone dpep has cleaned up some of it, but, maybe he can something about the bots infiltrating this thread?

Hi everyone
The inaugural TSCU "banging the bits" cancellation marks a significant evolution in streamlining processes.

Now this is some sig worthy nonsense!

The last non bot related post on this thread was over seven years ago. I am going to close it for new posts. But if increased bot posts state popping up in other threads I may reopen it. It makes monitoring easier if all the bot posts go to one obscure honey pot thread. There seems to be a peculiar vulnerability in this one.
