    I think the mechanical design of The Bored is finally done. I thought I had a lot more work to do, but its looking pretty good. I've moved the OLED between the pcb and backplate where it should juuuust barely fit. All the edges are now even and symmetrical, I think it's time to get a quote for machining the case, and get QMK onto the V2.0 PCB.

      Yeah thanks so far I need luck with programming. I think I might have fucked up the circuit on the bootstrap pins of the STM32 (of course I had to use an STM32 instead of an ATMEGA32u4 like a normal person).

      I'm still not sure about production, if there's interest I'll run a group buy, but I want to get the project more finished before I run an interest check. Like I want to be able to tell the machine shop how many to make as soon as I close the IC and get things moving, so I'll want to build one before hand. Also I'm imagining the unit cost of this thing will be approaching $300 a keyboard, which idk if people on r/mk will pay that for some nobody's design.

      Man, that is a bit steep (obviously not for the field, but for a nobody).

      I'm not sure, but the first quote I got for machining the case was $900 a unit and they couldn't even machine all the features. Granted, it was from a high end, US based, rapid prototyping machine shop so I should have expected that. I need to find a cheaper shop in china on Alibaba.

    Maybe, but I don't have any recollection of virtual COM not working on this port after a specific update. I just noticed it was being a little fucky a week or two ago. What's weird to me is if it was a software/firmware thing, it should affect both ports right? I'll have the Dell updater utility run to see if it can find any drivers or BIOS things I may need to update.

    Hackentosher replied to Hackentosher's status update

    I'm hoping it's not physical damage to the port, but I don't think it's that because I transferred 14gb of photos over usb 3 over the port in question and checked my usb 2 web cam on the same port and both worked flawlessly. Maybe there's a specific chip for handling COM on a usb port that broke? But I'd imagine that would be baked into whatever usb 3 chip manages the port. I'm blaming windows on this one.

    Hackentosher replied to Hackentosher's status update

    No I have definitely used both ports to interface with virtual COM devices before. This is a new thing. I've had my xps for going on three years now as a college student, so it hasn't exactly had an easy life (there's probably a few grams of aluminum shavings from my lab's cnc machine in the keyboard), but this seems like a weird windows issue to me. I think it's time for a fresh install once the semester wraps up.

    Okay the left port still works with usb 2.0 and 3.0 devices, but not USB-UART virtual com adapters. /shrug

    This is weird. The left usb port on my laptop wont support a usb virtual com port, but the right port does... Idek where to start to fix this one.

      Did this coincide with any updates by any chance?  In particular a windows update?  Microsoft has been messing around really hard with their updates with win10.  If so a version rollback might fix it.

      “Should” sure, but remember you have to add possible laptop weirdness.  This has the feel of a weird confluence bug that may be so rare microsoft might not fix it even if it was their fault and you could provide patch code.  Could also be they bunged up com ports on every windows machine.  So many things it could be though.  Possible bug report to microsoft and your machine manufacturer probably couldn’t hurt.

    Lol me too I guess OP needs to evaluate their own risk. If I was playing around with this I don't think I'd take a "probably" as good enough to let my guard down or feel safe around it. You're probably right that the sphere can't hold enough charge to sustain a sufficiently energetic pulse to be fatal, but again I wouldn't exactly feel safe around it.
  8. Hackentosher
    You're dealing with a lot of charge here, it's pretty damn dangerous as it is. I would find a lower voltage hobby if I were you. I Think your math on the voltage is right, given the dielectric strength of air at 3kV/mm at 50.8mm = 152.4kV. My intuition tells me it's less, but I haven't played around with voltages much higher than 240VDC. I just hope you know what you're doing. You've probably already seen it if you've gotten this far, but Electroboom has a couple videos on Van De Graff machines and Leiden jars, but again you're dealing with very high and dangerous E fields here. edit: Google tells me you need about 100mA through your heart to kill you, so lets do some math. I've measured the resistance across my body, hand to hand, to be about 150k ohms. Ohm's law tells us that 100mA*150kohms = 15kV. Meaning if 15kV gets connected across my body, I'll die. Just like that, lights out. Assuming your arcs are starting at 2" away from the machine and the approximation of 152.4kV is correct, if one end of your body is grounded and the other makes contact with this thing, you have an extra order of magnitude on the requisite voltage to push that current. Please be careful.

    Lol that's just technical speak for making the filament not turn as tight. The shallower the turn the easier it'll be to pull.
  10. Hackentosher
    So these often help straighten the path the filament has to take to get to the extruder. They also increase the bend radius it has to take. These adjustments together make it easier for the extruder to pull the filament. It may prevent a snag, but unless your filament has to take a crazy path from spool to extruder, it's probably not necessary.

    That might be a front panel audio or USB 2.0 header. Check the case manual or motherboard manual.

    Anyone have a car with a clutch delay valve delete? Been reading a lot about them and how they make modern manuals suck, but I'm not sure how much of the herky jerkies are my own noob driving.

    That's going to be tough, I don't think you can get a 5" + batteries and chargers for that budget. You may want to look at the Emax Tinyhawk freestyle. I have the tinyhawk freestlye ii and it's awesome. It's a little 2s 2", but it flies like my 5". Tons of power for the size and a bnf is about $125 USD.

    That's what I figured, the phone is through ATT in the US. I've never unlocked an iPhone before, do you know if it's challenging?

    Is this for a test? Looking at your images, the single sided board only uses through hole components on one side, and only has traces and surface mount components on the other. The 2 sided one has surface mount components and traces on both sides, I'll explain why in the next paragraph. Anyway, PCBs are usually made of a stack of sheets of varying thicknesses and materials. Some cross sectional pictures on this page will show more what I'm talking about. Usually, PCBs start as a fiberglass board with copper laminated on one side. If you need a two sided board (copper on both sides of the board, you stack two of these sheets back to back. More complicated and advanced boards add more sheets to create copper layers in between the outermost layers. These inner layers allow designers more room for routing traces, and have some benefits for signal integrity on RF/high frequency applications. The problem with adding layers is it's expensive. You have to etch each sheet of copper, and you can't etch the inner layers after they're glued together, so you have to etch them beforehand. This requires extra steps and extra material and is thus more expensive. You can also go the other way. If your design is super simple and you want to pull as much expense from the device BOM cost as possible, you can switch to a single layer PCB, where you only have copper on one side. This has a lot of drawbacks though, and presents challenges for designers because you can't stich a signal across the front and back (meaning if you need a trace to go across another one, you need to find a way around because you can't really go under it without a jumper). These days, 2 layer boards are so cheap that it doesn't make sense to use a single layer board except in cases of extreme cost optimization.

    77F (25C) is the correct temperature. Any colder and I'm shivering, any warmer and I'm sweating.

    I'm traveling to central America this summer, and I'd like to have some limited phone useage. I think I'm looking for a prepaid sim with maybe a gig of data, but I'm not sure. I'm also not sure how this will work with my locked iPhone 11. Can I just pop in a prepaid sim and head off to the races?

    As others have stated, in typical US outlets, the middle pin is a ground connected to Earth. Generally it's useful bc if something fucks up inside the device, the hot wire will short to ground and route current to ground instead of through something that could start a fire, or your body. The reason why we can't just use the neutral pin is a bit more complicated and has some pre-requisite knowledge associated with it. If you'd like to know more about that, I'd recommend watching this video.

    Any possibility it's in the trunk behind some of the carpeting? It looks like it's under the hood from a quick google, but I've seen rear batteries before on midsized sedans.

    This is another good suggestion. A lot of my friends use a Surface and swear by it as it offers a great note taking experience. I personally like to take notes on paper, but a surface or an ipad are supposed to be really good.
