You’ve lived there far too long then.
I’ve discussed this with my extensive marketing team and they agree that Dave is still the best name for this device
Schematic?
@akhlut Here’s the schematic and a draft of the PCB layout (the “PCB v0.1”). Any comments are welcome. My background is not in electronics. I’m a pure hobbyist so there’s likely a lot of room for improvement in the design.
Same. I just like to play.
Where can I find/buy/know what gaskets that will be good for this little project?
I’m not sure yet, I haven’t started yet, need measurements and it’s likely to be a couple of weeks before the display and parts get to me.
Once I have aRough XYZ values I can get an idea of what prr-made gaskets will for without much modification and then design the enclosure around that.
It may be easier to make a change in the enclosure for a silicon bead instead. Still too early to tell.
Is the display available on Amazon? I don’t mind paying a bit extra just so I don’t have to order though a Chinese site and wait for shipping.
I saw that one but I think it still comes from China so there is a long wait.
Thats still weeks for shipping even though its on amazon…
Ooops yah beat me to it!
Oh didnt know that
I should have bought one from Taobao when I had the chance
Found it with prime
HiLetgo 2.2" ILI9225 SPI Serial Port 176x220 TFT LCD Module with SD Socket Support 51/ARM/Arduino https://www.amazon.com/dp/B00LSG5HI0/ref=cm_sw_r_cp_apa_EQtYBbHMD4P7P
Edit I just noticed that link is the 2.2" display don’t buy that one it’s too big.
Nope, already tried that, they flagged my post so I deleted it. Different screen/module!!
Yeah just noticed damn
I was looking for some dimensions to get started on a case concept. I found this. I assume this is accurate on the hole dimension and that the doughter PCB will have the same hole spacing? Apparently wrong, this is the 2.2" size.
I went ahead and made a quick concept as small as I could make it. It uses a 3mm piece of Acrylic to cover the screen that should be epoxied to the case. Four M3 Socket heads hold it all together and compress an o-ring on the bottom for “water proof” ness. There is still a question about water proof buttons, for the communication cables I would just expoxy / hotglue where they come out the case. The bottom part I did not model yet. The schematic from @janpom showed two buttons that’s why there is two round holes on the side.
Also I am sad to say its going to be too big to fit inside the truck bolt pattern.
Bottom side where o-ring goes, then compress by bottom half part not shown.
PCB assembly.
Cross section.
All of the vertical dimensions for the PCB’s are just a guess at this point.
Anyone know of some really small waterproof buttons?
*Thought. Maybe the case does not need to be two parts with o-ring. Once you confirm it works, fully pot the inside with epoxy and use the 4 bolts to attach it to the deck. Well that is one way to get it done! Actually you need to disassemble to re-program it if there is an update to the firmware, so fully potting it would not be good idea.
Make it landscape? Thats what I am going to do if making it landscape is possible @janpom
I am probably going to have mine cnc aluminium - probably cost more than the electronics itself lol
Please make it step-onable for us shortboarder
I think a different design that acts as a foot stop would be dope for my short board
