RE: Thinking of a new gadget... - Csory_imp - 08-31-2019 Max: This uni-mount idea is great. However, it is outside of my mechanical skills and capabilities - can't see how I could print it and make it tough enough to resist vibration... There should be some short of a tensioner mechanism to make it stay at the selected angle... The rotary can't be permanently installed on the wiring since it is non-waterproof - the 6-pin socket, on the other hand, could be. My initial reservation re: one universal unit was that it would be ungainly thick to look nice on the center mount. Now working on a visual prototype for that - will be about 3.5mm (0.14") taller than the standalone display... If people would more like to have a single unit I might change plans and go with that...

An integrated (thicker) set-up would be desirable, but not be necessarily locked down in a wedge mount. However, since the display digitally supports inversion, that could be a moot point. A scaled sketch could clarify the fashion. RE: Thinking of a new gadget... - Csory_imp - 09-06-2019 Created an all-in-one mock-up. Parts are in, but still waiting for the new circuit board (this version ended up being a complete redesign to shave off as much height as possible). It is now a single module (everything is built behind the display). Horizontally is about 3mm=1/8" less than the previous one. Height was increased by 3.5mm=5/32" - this is where all the original "central module" electronics are crammed in now. See the image below to visualize the difference: new (all-in-one) is to the left. Please let me know if you prefer this "all in one" over the previous two-module design. Will also send a PM to those who were interested... RE: Thinking of a new gadget... - Csory_imp - 09-15-2019 Finished protoyping the all-in-one version. The main problem was eliminating the original power supply and building a much smaller one to make the unit as flat as possible. Switched from 3x2 to 6x1 pin header for the rotary and programming connector for the same reason. There are a few more tweaks to be done - the ambient air sensor placement is a bit off, and still waiting for a special ultra-low-profile inductor from Japan (that will shave off another 0.75mm if it works). Will keep using the flat ribbon cable for the first 5 inches since that is easier to conceal. Those of you who were interested opted for the all-in-one, so I abandoned the two-module design. RE: Thinking of a new gadget... - Lord Popgun - 09-15-2019 I have to say, you do nice work Csory RE: Thinking of a new gadget... - peterbaron - 09-15-2019 Marvel RE: Thinking of a new gadget... - Bazbro_imp - 09-15-2019 Spot on, Csory. Lovely job.
RE: Thinking of a new gadget... - GoldOxide_imp - 09-15-2019 I think Csory just likes to 3D print whenever he can.
RE: Thinking of a new gadget... - TwoBrothersBusa_imp - 09-16-2019 Looking good sir! RE: Thinking of a new gadget... - Csory_imp - 10-07-2019 Time for an update It's been quite a while since the last one - and I've been busy with tweaking the final design. First thing first: the new inductors are in, work flawlessly, and the new power supply design ended in significantly lower power consumption. Now it is 5.3mA with backlight off, and 7.3mA with backlight fully on (both measured at the 12V input). The smaller inductor allowed a smaller Schottky-diode (0.5A instead of 1A), making the 6-pin socket connector the tallest component on the board. This made me put on my thinking cap: if only I could put the connector side-by-side instead of on the board... ended up redesigning the entire PCB, flipping it upside down and creating a "notch" for the connector (on the left side): Also, reduced board thickness from 0.8mm to 0.6mm. These two changes shaved off 0.8mm thickness of the display module, as you can see on these newly printed housings: While still waiting for the new boards to arrive (due in this Thursday), worked a bit on the software too. Main changes are: - Option to use icons instead of text for "oil" and "coolant" temperature, see image below. The black "drop" represents engine oil, while the horizontal lines were meant for coolant (reminds me of a radiator grille): - Advanced setup now skips steps that are non-relevant in the given configuration (i.e. coolant sensor adjustments will not show up if there is no sensor attached). - Connection error with sensors will show "N/C" message instead of garbage temperature values: - This is a hardware change, but has software implications: with the more efficient power supply I could double the system clock. This also doubled the frequency of backlight switching - now looks even smoother when dimmed. Also, five set of cables are ready. The one with the rotary button is for adjustments, the other one is for programming. Opted for 90-degree connectors on the BikeGadget's end, allowing better access when the display is already mounted on the bike (see below). Once the new boards are in I'll go ahead with manufacturing and - finally - sending the units out
