Pushed some updates to the github repo today. Added a day/night display brightness toggle (saved in EEPROM), and also uploaded the KiCad and Gerber files I used to print out a PCB (old protoboard version above, new PCB below):

Thanks for the offer, but I'm not looking to sell or trade for these at this point. (I might change my mind if someone designed and shared a rad 3D printed enclosure )

This is an awesome project, thanks for posting it! It's very similar to something I've been wanting to do, right down the Teensy, form factor and data source.
I'd love to work with you on an enclosure, I have a 3D printer and I'm reasonably handy with Solidworks. Shoot me a PM or something with what you might have in mind and some dimensions, I'm no automotive designer but I can at least have fun with it Which screen are you using? My main sticking point currently is choosing a screen that I'll be able to make a UI for and refresh fast enough...I'm a lot more familiar with the mechanical/discrete side than coding a display and UI, and I'm a bit lost. |

The case would have to support repeated opening and closing too since the SD card needs to be removed to download the logs. The hardware I used, including the screen, is listed in the README on github: https://github.com/jasminpatry/boostino#hardware. The KiCad files are there too so you can get some dimensions from that. I can take some measurements of the screen and DM them to you if you want. The code is all there too, so you can see how I'm updating the display. In short, the canvas is double-buffered, and only the pixels that have changed are sent to the display each frame. This is done by ILI9341_t3::updateRect8BPP() in my fork of ILI9341_t3, which is called by UpdateTft() in boostino.ino. |

Thanks for the info on Github, I admit I hadn't looked at it yet so I'll check that out! |

Got the Tactrix-less version up and running this weekend, and pushed everything to GitHub. I switched to SMD for most components to make things fit more easily. Top is old v1 board, bottom is new v2 board:
Now I can leave the gauge plugged in without worrying about the Tactrix draining my battery |

It's been a few weeks, but I've been busily working away on this as time allows.
The Teensy has been great for prototyping, but it is relatively expensive and limiting in terms of form factor, so I decided to switch to a custom MCU board. I settled on an STM32 microcontroller (the STM32F429ZGT, which is roughly equivalent to Teensy 3.6 in terms of speed, flash, and RAM), and have spent the last few weeks porting everything over and working out the kinks. I'm happy to say that that's nearly done (the second revision of my PCB should be here next week, and hopefully won't have any new bugs). I've also designed a laser-cut enclosure that I'm excited to get my hands on (should also be here next week). |

Thanks, I'm not quite at that point yet but I'm hoping to make them available for purchase soon! I have a friend testing one on his Ver.8 STI-swapped RS and it's working great for him. I will probably be looking for more testers in a few weeks...

This is cool, but when you are ready to actually offer a product for sale here you WILL have to do this-

First update here in a while! I’ve been more active on IG — follow https://instagram.com/gfxgauge for more frequent updates. Since my last post here I’ve gone through a few PCB revisions and added support for oil temp and pressure sensors, along with a bunch of software improvements (menus for choosing what to poll & log, an info display, support for a wide range of subie models, etc.).
I’ll be at the BigNW meet this weekend in Portland OR if anyone wants a demo. DM me here or on IG, or email [email protected]. |
