It’s been more than a year since my last progress report, and about 1.2 years since I bought my 3D Printer. I have made some updates to it, which I’ll be describing below.
I changed my networking setup and switched from Proxmox to Ubuntu, moving most of my services to containers.
This Christmas I visited Switzerland and Liechtenstein. I used the chance to visit the Rhine Falls, visit Vaduz (and send a couple of post cards), travel on the Swiss highways 13 and 2 (through the Alps), and visit some Swiss towns.
So, this is not a tutorial, but a showcase of a project I recently build for HackTM 2018 together with a few colleagues from college. The project consists of 3 main components: a raspberry PI with a webcam (and optional display), that will be placed next to an automated door, which will run a face detection algorithm; a webserver running a Flask API and a face recognition algorithm based on OpenCV and finally and administrative progressive web app (what they are is apps that are installed seamlessly when you visit a webpage, and which can then provide offline access to data) for managers to see when their employees are at work.
About 2 month ago I bought a Tarantula I3 3D printer from Aliexpress. After getting it through customs and assembling it, I must say it is one of the most challenging and rewarding projects I have ever worked on. I only had time to work on it during weekends, but now I must say I am quite satisfied with the results. There is room for improvement, but that will come at a later date.
Sometime ago I decided it would be better to build a moderately powerful VM server instead of having many cheap PCs. This way it would take up a lot less space and consume less power. I build mine using second hand hardware, and named it Tesla.
Finally all my networking hardware, servers and UPS are in the same place. I also did some cable management, but since I’m trying to do this in an old cabinet it is quite difficult to make is both accessible and beautiful.
Ever wanted to connect to a VirtualBox VM via SSH, SCP or others and found out you couldn’t? This is because, by default you don’t have access to the ports of your VM. Today I’ll show you how you can enable port forwarding so you can easily connect to all your VMs.
