Measuring environmental aircraft noise (Zelfbouw meetstation voor meten vlieghinder.pdf – Google Drive)

Posted by jpluimers on 2022/10/12

I’ll be following this guideline (or maybe by now already have): Zelfbouw meetstation voor meten vlieghinder.pdf (Google Drive) This is what I needed: If you do not have a Raspberry Pi, then you can get it from them as a package for EUR 115 (including case, preinstalled microSD-card, charger and WiFi adapter):[Wayback/Archive.is] Raspberry Pi Zusatzkit zum Komplettpaket Lärm (with configuration manual at [Wayback] Anleitung Raspberry.pdf)

DroidCam – Webcam for PC – Apps on Google Play

Posted by jpluimers on 2021/12/21

Since most phones still have better cameras than most laptops, this is on my list of things to try:

Android app: [Wayback/Archive] DroidCam – Webcam for PC – Apps on Google Play (there is also an iOS app, but I don’t use iOS devices)

Client software for Windows and Linux:  [Wayback/Archive] Dev47Apps

DroidCam turns your phone/tablet into a webcam for your PC.
Use it with chat programs like Zoom, MS Teams, and Skype.

Main Features:
– Chat using “DroidCam Webcam” on your computer, including Sound and Picture.
– Connect over WiFi or USB cable.
– Unlimited free usage at standard definition.
– Keep using your phone with DroidCam in background (Android).
– Simple, safe, efficient, and trusted by millions of people worldwide.

DroidCamX Pro Features:
– Switch to HD Mode for 720p/1080p high definition video.
– Camera controls: toggle light, enable continuous auto focus, zoom in/out.
– Rotate, Flip & Mirror the video to better match your setup.
– Adjust brightness, contrast, add video delay and adjust audio volume (Windows).
– USB-Only mode for extra privacy and security.
– Option to auto-mute phone calls.
– No Ads.

I am really curious how they did this on the software side: developing and signing drivers; low-latency communications protocol, etc.

GitHub – dschmenk/apple2pi: Apple II client/server for Raspberry Pi

Posted by jpluimers on 2020/05/28

[WayBack] GitHub – dschmenk/apple2pi: Apple II client/server for Raspberry Pi: hybrid computer of a Raspberry Pi inside an Apple II (either ][, or ][+, or //e) so the Apple II can be a front-end to the Raspberry Pi which then can run an Apple IIGS emulator, talk to the Apple II storage hardware and much more.

It can run [WayBack] RASPPLE II: A2CLOUD, A2SERVER, Apple II Pi for Raspberry Pi

Going to test some USB 3 gigabit ethernet adapters based on Realtek RTL8153 and Asix AX88179 chips

Posted by jpluimers on 2018/07/27

Later on, I might add a USB31000S in the mix, but I will do some initial testing with USB 3 gigabit ethernet adapters based on Realtek RTL8153 and Asix AX88179 chips.

Things I will focus on with my Retina MacBook Pro 2015 model are:

  • CPU usage
  • Throughput
  • Duration between reconnect on USB after suspend, and renewing the DHCP lease
  • Promiscuous mode capabilities

Some links for my references:

A first impression from the above links is that for Realtek chipset based devices, drivers are more readily included in operating systems, and these chipsets are better at VLAN handling.

USB Typewriter — Classic Typewriters for the Digital Age (for mechanical typewriters, not electrical ones)

Posted by jpluimers on 2014/03/19

Nicely done: the USB Typewriter — Classic Typewriters for the Digital Age, as they can do almost all keys a PC keyboard can do see the USB Typewriter — FAQ using a mechanical (not electrical!) typewriter.

Basically the opposite of  the IBM Selectric Computer Terminal, the Daisy wheel printing, the IBM 1050 systemand the IBM 2741 Console.

Note the kits (there are both soldering and non-soldering versions) are mostly aimed at models that once were popular in the USA, so for manufacturers like Adler there are no guidelines (but the existing guidelines for soldering and for non-soldering probably work fine).

How To Backup Bootable USB Drive

Posted by jpluimers on 2012/10/15

I needed to make backups of a couple of maintenance USB drives.

It turned out to be pretty easy: How To Backup Bootable USB Drive describes how to do that based on a small USB Image Tool developed in .NET.

One of the things you can do with this is backup bootable Windows installation media.

Note it is a simple tool, so it backups only same size to same size. For more advanced copy purposes, use something like the professional tools from Acronis.
