Mounting VirtualBox RAW disks

Posted December 2, 2017 By Landis V

Cleaning up some VMs this evening and wanted to mount a RAW disk partition I’d been using with an old VM. Surprised to find that a simple ‘mount’ wouldn’t do the trick. Fortunately pretty easy thanks to the info at the following link – use parted to get the offset and add that as one of the mount options.

DIY HDPE Blocks

Posted October 24, 2017 By Landis V

Had a post a while back with a link to a Garage Journal forum thread where a guy did some great tool organization by milling HDPE blocks. Some info on DIY HDPE blocks.

And machines for working with plastic (shredding, extruding, casting, etc.).

Also read some things about using HDPE as a filament for 3D printing.  Not as easy as PLA or ABS, but sounds like it is do-able.

IR remote controls revisited

Posted July 22, 2017 By Landis V

I posted a while back about building a device to use as a universal remote control, where I could program commands that were relevant to devices in my living room, and have since been thinking about taking further actions towards integrating them with Alexa. I have a Harmony Hub, but the whole scene thing just doesn’t do what I really want – or does so in a kludgy fashion – most of the time. I’ve run across a few things in the past few days that might be useful in furthering the concept. The webmote link in my previous post may also be a viable option, since I’ve picked up some Arduinos and a tinker kit since I posted that – hoping it contains an IR receiver.

Right now, just need to get some tabs closed out, so posting a few of the relevant links I’ve run across so I can revisit them later.
Irdroid USB Infrared Transmitter, around $30
Irdroid-RPi Transceiver, around $20
irkit open source IR transceiver
