mplayer is a great tool for playing videos on an external monitors (typically videoprojectors) without displaying anything other than the video content.
A proper config file can automatically run videos in fullscreen and borderless, pushed properly to the side so it displays automatically on the external monitor and with an OSD level of 0.
Hey Mastoworld !
So last week I got tired of being overwhelmed by the stack of things to do at work (for abysmal wages too...) and for my lack of improvement in my personal projects.
So I came across this book by David Allen "Getting things done" that I had lying around and had read a few years back.
Decided to read & apply it again.
And it's empowered me back into control of all the "stuff" lying around everywhere.
Highly recommended !
This is an interesting read (~15min) on why freaking around about an AI-arm's-race between the US and China is an empty idea.
AI is not necessarily improved by simply throwing massive amounts of data at it, and improving AI research does not justify #CorporateSurveillance.
This morning, I filled out a form to contact some french administrative service to which I owe money for income I declared end of 2018.
I've been using µMatrix to filter out third party-requests unless I check them out, and needless to hint google is everywhere and always blocked.
Well, just to validate that form I mentioned I had to check in google **just** to get the captcha. That's just lame. 😠
Can't we build an anti-bot captcha like system that's open and **not** google ?? 🤔

Jenny i3 Revamp : Why I'm designing my own X-carriage
The MK8 extruder seems nice, but I've been encountering a few hiccups with it and the i3 1.5 Rework architecture.
I'm designing my own X-carriage to accomodate the mK8 with the Z probe sensor AND a fan that can effectively cool the print, which is absolutely necessary to achieve proper prints.
I couldn't find anything that matched all these criterias to my satisfaction so I started drawing my own from scratch in #FreeCAD
Jenny i3 Revamp : Soldering pins on the RAMPS board
For some obscure reason there were two slots ready for two male pins that weren't already soldered on the RAMPS 1.4 board I had bought years back for Jenny.
The RAMPS board is an all-in-one shield for Arduino Mega boards transforming it into a 3D printer motherboard capable of controlling stepper motors, reading temperature sensors, endstops, etc.
The missing pins I needed were for powering the extruder fan for cooling.
Jenny i3 Revamp : Making up for lost time (2 weeks)
My previous toot on Jenny's revamp is dated 28/02.
In the meantime I've done the following, more or less in this order :
- cable electronics
- discover I'd have to design my own X carriage
- redraw the MK8 extruder and start designing a custom X carriage
- flash the firmware
- connect to a controller and start debugging the firmware
- set the current limit on stepper drivers
- solder missing pins on the electronic board
Well ! I haven't tooted in a while now. A bit over two weeks if I'm not mistaken.
But I'm still here ! A week of vacation followed by an overladen week of work has kept me silent, but my projects (and particularly Jenny's revamp) haven't stopped. I just couldn't manage time to toot about it. I'll be preparing a series of toots to catch up what's happened these past two weeks.
Jenny i3 Revamp : Making some custom length bolts
I had a problem yesterday with my X belt stretcher because I didn't have an M3 50mm bolt, and couldn't get my hands on one in the hardware store.
What I could find, however, was some 3mm threaded rods.
I bought one & cut a 50mm piece. A bit of epoxy glue and a nut and I had what I needed.
Had to reprint the X stretcher though, I had ruined the first one in failed experiments.
Jenny i3 Revamp : Getting to know the MK8 Extruder
The extruder is a part where you can have a bit of fantasy of your own and go different ways.
So I'm forking a bit away from eMotion's Tech i3 since I've had this MK8 I bought off the internet a year or so ago for Jenny's (future) upgrade.
I printed in a lesser quality filament a part I found on thingiverse.com to fasten it to the X Carriage. I had to completely dissassemble it to get it in though.
No better way to get to know it 🙂
Jenny i3 Revamp : Fully assembled
Immediately following my previous toot, Jenny's new frame is now fully assembled and tightened.
The rigidity, as compared to the Mendel i2 frame, is impressive.
At the rear you can see the two added threaded rods making a right triangle to improve rigidity. As previously tooted, directly incorporating a design upgrade.
All the motors are in place as well.
I'll be working on the extruder, heatbed and GT2 belts today.
Jenny i3 Revamp : Fully disassembled
I haven't posted in a few days, I've had a busy friday and a busy week-end but Jenny's revamp has kept a steady pace, everywhere I could fit an hour or two to keep working on her.
Early this week I fully finished disassembling her previous frame which is nothing more than a bunch of printed parts, rods, nuts and washers now.
The cycle of RepRap is complete from birth to death I suppose.
Tech enthusiast. I love open software, open hardware, tinkering, breaking things to pieces and building stuff.
