On the 20th February the EU governments approved the current text, the way i understand it, it next goes back to the EU parliament for a final vote.
I ve found a quick summary of the problem with article 13 on youtube.
There are also numerous articles from the EFF and basically everyone else about the directive. So whichever news site/creator you like, chances are (s)he said something about it. The really interesting or should i say scary part is, ive yet to find someone except the politicians and lobbyists who push this to be in favor of this change.
So who will the winners and loosers of this likely be if it passes ?
Btw i almost forgot, the next EU parliament election are very soon. If you live in the EU please vote, no matter if you like or dislike the EU copyright directive, vote for the party you believe is best.
If you want to know how the members of your parties voted about the copyright directive, thats available on https://saveyourinternet.eu/act/ (currently its the previous vote, iam not sure how this page will change after the final vote).
Today the EU Parliament and council negotiators have agreed on a final Text. Next IIUC are the final votes of the various institutions.
I have not had the chance to fully read the text, just 1 page that was quoted on Twitter. So iam not in a position to really say what it means but what ive heared earlier today does not sound reassuring. Nor does it feel great that the public (like for example me) seems to basically depend on "leaks" from the law makers to know what is going on. Whats in the text, and so on. The EU should make their proposed texts and _ALL_ discussions fully uncut and un-delayed public.
The way oil radiators work is that the oil inside is heated by electricity flowing through some resistive heating element. The heated up oil then raises due to lower density and that way circulates in the radiator which then gets hot and heats the air.
Noise is produced by either mechanical thermostats or relays, so every time the set temperature is exceeded by some fixed amount some mechanical switch or relay switches which makes a click. That can be annoying if one tries to use a device like this in an otherwise silent bed room.
The top can be removed too after that and after removing the handle.
To replace the relays 2 solid state relays from ali express are added, they are rated at several times the needed current (i expected the rating to be exaggerated when i ordered and wanted to make sure they arent underrated but it seems the seller actually was honest with the rating). Careful attention is also paid to their heat-sinking requirement (which is none at the currents they would be used with).
Was there some part expanding from the heat and making a noise ? something on the 2nd board i didnt look at ?
Ok back to the silencing, the solution here is in fact very simple. As the 2000W and 1300W modes are fake and only sustain 700W anyway and i have to assume for a good reason. The solution is to simply disable the 1300W part.
In 2 days (on 2018.09.12) The next vote on the copyright directive in the EU Parliament will occur.
Resources about the draft, which IIUC will be voted on are available on https://www.saveyourinternet.eu/resources/. If you live in the EU and feel that this proposal is bad you can use https://saveyourinternet.eu/ to contact your representatives.
There are also 252 proposed amendments, iam not sure these will be voted on or not (i thought they would but the timeline seems too tight to really do that).
Also there will be EU parliament elections in a few months. If you live in the EU and care about this, check how the parties voted on this directive and other directives that may affect you before you vote on who you want in parliament. Politicians of all parties are very dishonest, only by looking at past actions can one with any accuracy predict what they will actually represent. No politician would ever say they intend to vote in a way that the audience of the moment dislikes.
When i experimented with measuring the amount of particles from my 3d printer, i noticed the majority originated from when the heat-bed was turned on. I had cleaned the inside of the printer roughly before, so this was slightly odd. More investigation shortly later revealed the cause though.
The use of tinned multi-core wire without ferrules. Why it was done this way you may ask? Because between the incomplete and poor official documentation, the consumer made videos of how to assemble it and my plain lack of knowledge about how multi-core wire with and without solder behaves in this case. This way of connecting the wires seemed sound enough and there also where no ferrules included with the printer kit.
That said if you did connect high current wires in a similar fashion, you probably want to consider redoing it with ferrules or in another reliable way, like directly soldering to the board or soldering a solid core wire onto the multi-core as an intermediate. Also keep in mind iam a programmer not a expert for this so do your own research if failure of a connection could have some real consequences.
I didn't had any fitting ferrules, so the way i fixed it was to take some terminal connector thingies, which when one cuts half of each off are basically ferrules. I also didn't had a new terminal block that was rated for enough amps to replace the roasted one. I will properly replace these once i have proper replacement and have time. Quite likely next time that printer needs some kind of "service".
A while ago i read about 3D printers spewing out nano-particles into the air, especially ABS. I was curious if i can actually measure this on my own printer and how to fix it.
My plan was to use a cheap air quality detector, that i bought previously. It has to be noted here that the device detects particles 300nm and larger while what i read seems more about 100nm and smaller particles so its not 1:1 comparable.
Before anything i used my vacuum cleaner to very roughly remove large visible crap from the inside of the printer enclosure.
First baseline measurement, with the printer on, no heating yet.
Can we reduce that particles/dust ? Lets try properly cleaning the enclosure with the vacuum cleanerto use a stream of negative ions to ionize the particles, so it sticks to something and doesnt stay in the air. As can be seen this is a effective way to clean the air, or the measurement device is affected by the ions.
Adding a wire between ground and the frame (with a 1k resistor between) stops it from charging up and seems to resolve this problem.
Now question, what happens if we try to print with the thing on?
Taking an image every minute from the air quality meter shows that within about 6 minutes after the print started the particles go to 0, it does rebound slightly and fluctuate around 0 after that.
The print finishes without problems after 36 minutes. Originally i intended to repeat this with other filaments but as the biggest dust/particle creator seems the heatbed or rather air convection from its heat. This would need to be setup differently to eliminate that. As it drowns out new particles from the heated filament. But still this shows that for less than 4 euro shipped one can get a device to eliminate at least larger particles from the air within the enclosure of a 3d printer. Compared to a filter this is probably easier to setup as well. Further experimentation would definitely make sense. Though simply having an enclosure and opening it together with a window for 5 minutes probably removes most particles, if one is concerned about it.
