Yeah, it's completely custom. Combination of CNC'd aluminum and 3D-printed stuff -- I wanted the install to be as clean as possible, so it bolts onto the existing gauge mounts with two bolts, fits the existing speedometer cable, and uses the existing wiring harness (albeit with a new fancy multi-pin waterproof connector to replace the bullet plugs). I can pull it off to work on it in thirty seconds.  All the wiring is point-to-point on protoboards, because again, v1.0 -- once I figure out the proper display technology I'm going to get some boards fabbed and that'll probably shrink the housing to like 30% of the size. e: here is some of the electrical stuff to filter the spark plug signal. That green trace is a recording I made of the raw signal, and the others are SPICE simulations of the filter circuit. The thing works astoundingly well; I am not even doing any filtering in software, and I've literally never seen the RPM glitch out. It was the first time I'd done any serious analog electronics work so I'm pretty stoked about it.

Do you do that kind of work professionally? Because my attempts at getting a model made for 3d printing is about like folding origami with mittens on. It's easy to visualize what you want, but when it gets down to measurements and materials and not forgetting anything it gets bad fast.

builds character posted:Goddamnit sagebrush, will you please make more of those so I can buy a hawk gt to put it on? I'm working on it!!! The OLED in the current version, while gorgeous at night and on overcast days, is not suitable for full-sun usage and also it's a custom-ordered non-stocked part. Also there's probably like 50 hours of painstaking hand soldering in the circuitry and no one is gonna pay me enough to do that again. So the plan is 1) try out a couple of new display technologies (monochrome negative-mode TFT with an RGB backlight is my current direction) 2) refine a few other hardware things like the tach LEDs, the temperature sensor and the internal power regulators 3) design a proper circuit board for all this poo poo and have it fabbed up 4) redesign the housing for the new smaller circuitry 5) make a v2 prototype with all of the above improvements 6) ???? 7) profit

In your opinion would this still be an issue on a car as a speedo/tach display sunk into a dash?

Mostly the former. It's plenty readable in the day as long as the gauge is shaded -- I'd say that anywhere you can see a cell phone screen, you can read the OLED too. I do have a small hood over the screen on the bike to avoid direct overhead lighting, but whenever the sun hits it dead-on, it's just not capable of keeping up. You can still see the digits but they're faint and you have to squint and that's not acceptable, particularly on a bike. So yeah, motorcycle-specific issue. It would probably be just fine sunk into a dash in a hardtop car.

I think any digital display is going to have problems if the sun is shining directly on it. I commute home with the sun at my back and there's a couple miles where I can't read anything on the instrument cluster because the sun is blowing it out, and this is a stock dashboard. Chalk that up as a win for traditional mechanical gauges.

An e-ink display would look cool as hell but I don't think there are many big ones out there that are homebrew-friendly (e.g. cheap). I wonder if there's enough interest in a homebrew car electronics thread.

I commute home with the sun at my back and there's a couple miles where I can't read anything on the instrument cluster because the sun is blowing it out, and this is a stock dashboard. Only the transmissive LCDs are hard to read in the sun. Transflective displays (like a wristwatch or an old game boy) use reflected light and are perfectly readable on sunny days, and can use a backlight at night. Disadvantages are that they're monochrome, the refresh rate is kinda slow and the contrast isn't anywhere near as nice as OLED, but the better versions are pretty good. It's getting harder to find monochrome anything, though, which is kind of a bummer because if you want a retro aesthetic the full-color transmissive ones just aren't as good.

Sagebrush posted:i felt a tingle in my dingle Unf. Yeah, this is the direction I'm talking about. I'm all about cool graphics, so I'd like to start with the TFTs and some supercar-style gauge layouts. Monochrome digital stuff is neat where appropriate, but I'm trying for a little more modern, in this case. That said, I love the gridline horizon all day, every day, and the "Hawk" splash screen...   This also reminds me that I *need* a 3D printer.

It's a Chines Prusa i3 clone, but supported and improved by Monoprice. Seems to be considered among the best budget 3D printers. If you want to get started small, the Select Mini is $220. There was an eBay deal that knocked it below $200 earlier in the week.

I hear good things about the Creality CR-10. The print volume opens up a lot of possibilities that other printers don't have. That cupholder I made for the 911?: https://i.imgur.com/EvJEM5n.jpg Had to print it into two pieces and glue together cuz the base was so large. Would have been so much easier modeling in one piece.

My Rostock (RIP: sold a few weeks ago) could print an 11 inch diameter, 14-inch tall cylinder. However, I used the height for maybe two prints in the three years I owned it. The Creality or the Monoprice V2 may be more my style in the future.

Guess it's been a while since I looked because I remember everything being way more expensive. Plus when browsing around I fall into the trap of "I need a giant build area!!" The select mini seems to have issues where it starts out cheap then you have to start modding it to keep it in good shape.

Ten times what my OLED cost) You can also get these stunning orange plasma displays that are like the most beautiful thing I've ever seen. They still make them as spare parts for one particular use: some kind of MFD on the AH-64 Apache. A 6-inch display (no driver circuitry) is like $1800 used

I started from recent posts and have just kept up with it since I'm not in a rush to soak up everything. Still a lot of it doesn't make sense but I'm picking up bits and pieces. Dunno what your end game is, though. Mine is first decide if I want a printer then get an idea of which ones people have and like, and which would suit me best. Which sounds like the Prusa MK3 since it's more expensive but the easy button of printers that just works. Though it may not print the biggest big stuff, which may change my mind even though I have nothing in mind to print in the first place.

I don’t have a printer, yet, either, and am soaking up info much like Larrymer. I’d really like a Prusa, but budget says I’ll probably get the Monoprice. I also have a couple of need friends who have printers I can bother for help. One just built his own using a pile of parts and aluminum strut. He wanted it *rigid*.
