This is almost identical to my journey. Except it was the fact that I (my parents) could not afford a copy of Visual C++.

You could find these under $100 yesterday on AliExpress with some referral + coupon stacking (rakuten + coupon + paypal pay-in-4 discount). The cheapest sellers often only put out a limited number of items each day, so you have to check back every few hours.

Is your 6502 SBC in any state to share more info on? It seems like an interesting project.

I have often heard the feeling called "squick". Or being "squicked out".

> (and there was some startup - in NYC I believe - that you could give Eagle files and a product order list and they would buy you the components at Digikey and manufacture the board for you... anyone remember their name?!)
Are you thinking of MacroFab (https://macrofab.com/) located in Houston? I believe they have been featured here before.

In my experience, the vending machines near and in hotels, etc, did not require any form of ID. However, the random ones I found out on the street required you to have obtained an ID/Authorization card beforehand.

A large part of these technologies making their way into consumer automobile engines was advances in material science, lubrication, manufacturing, etc, that allowed for them to exist economically and reliably. Those WW2 era piston engines were horrifically expensive, and required dozens to hundreds of hours of maintenance per hour of flight time.

I couldn't stand the constant nagging and focus-stealing the Razer software did regularly. To the point that I just went back and bought the same Logitech mouse that I had been using before (and had broken). That's what I get for trying new things occasionally.

Have you ever written up or documented the technical aspects of your whole process to scan one of the cartridges you receive? That would be something that I would find interesting to read.

As a hopeful note of optimism: I recently sent a large, expensive package (worth around $1500) cross-country via USPS. The package was sent out mid-December. According to the tracking it made it all the way to the destination Post Office. After that...nothing. It just never progressed. I filed both a mail search requests, and an insurance claim. I received nothing but radio silence on those as well. Fast forward to about a week ago when the package just shows up on my doorstep without notice. Hopefully byuu's package eventually does show up.

When the ESP8266s were first introduced, they came with a closed firmware that simply responded to AT commands over a serial port. To do anything with the chip, you had to have another micro controlling it.
However, sometime after the hobbyist/maker market started to take notice of the devices, an SDK was released, allowing for code to be run natively on the devices without a separate micro.
Nowadays, there are multiple options for running code on the devices. You can do it natively via C/C++ with the SDK, or you can try out one of the other firmwares that various parties have produced, like NodeMCU (Lua) or MicroPython.
The chips are actually pretty damn powerful compared to the Atmega series micros used with the classic Arduinos. And cheap too. You can get a NodeMCU module that already has a voltage reg. and USB->UART controller on it for around $3. Very hard to beat.

Either not getting a good ground, or not having a long enough antenna are two issues I have commonly seen with some of the more basic kits.
