Amazing machine & amazing job, both software and hardware!

Tinkercad is one of the most intuitive modeling software, which can be used directly in your browser (nothing to install). This improvement gives it a real boost in usability, as it allows you to tweak a design without having to redo it all with the mouse (aka: parametric modeling). This is less intuitive, but more convenient and usable, and still easier than a complete language like openscad / http://www.tridimake.com/2014/09/how-to-use-openscad-tricks-and-tips-to.html?m=1
If you are #3dprinting with Tinkercad you can now use visual programming to build designs!

If you want to do a quick design for 3D printing, Tinkercad is pretty easy to use. Although it was briefly in danger of going out of business, it was bought by AutoDesk who have made a lot of improvements. It is possible to program and simulate an Arduino…

Tiny pretty blurry world :) These are easier to make than MEMS though (see my former post https://plus.google.com/u/0/+JeremieFrancois/posts/aULEVUXt6sS)
Even in a tiny little 0603 SMD package, an Inductor is still just a coil of wire? #mindblowing #tiny

I mostly use TronxyX1 printers for a fast-track training on 3D printig... This one is my slowest purchase ever on Banggood. My first batch was delivered in ~5 days by DHL, but this one took a little more :D Actually it is so late that I forgot about it!

Seriously, the +Wall Street Journal just lost any kind of value to me due to this very stupid article https://www.wsj.com/articles/the-sea-is-rising-but-not-because-of-climate-change-1526423254 The fact it was so poorly corrected afterwards makes it even worse (see link below, the WSJ article is behind a partial paywall and I read it before I got kicked out). Even though we may not expect a lot of humanism or philantropy from the scientifically skeptic Fred Singer, a regular writer for «major» newspapers, we could at least expect he would not insult the readers of the WSJ with criminally stupid and blatant, self contradictory statements. Hey, I am not even asking that they are true, but that they are plausible at least - I mean, is the WSJ targeted at uneducated apes?

This is not even an rant on raw, short-sighted capitalism, but simply raw, basic stupidity regarding obvious global economy trends... and 10 year old level logics.

Seriously, he must get instant cash via bribes so large, that he keeps on defending dubious causes and the oil industry in such a childish manner, without thinking about investing half a minute in better arguing. Or, invest some of his stock in the increasingly promising renewable economy, and then, promote it for more profit. Eh, wait, given how ridiculously contradictory and shallow his arguments are, I would not be surprised he plays on both fields.

Sadly, it also means that the WSJ underlying support is fine with such dickheads as authors/editoralists. It says a lot of the people who rule the world with their money. Anyhow, given the tone of the journal it could be rebranded the the OIJ, aka the Oil Industry Journal (//eg. By The Editorial Board / June 29, 2018 7:36 p.m. ET / The first wave of lawsuits to make oil companies atone for their alleged climate sins was beaten back this week(...). *One hope* is that this victory for judicial sanity will stop the tide of litigation from spreading across the country.//)

Yet another example of crediblilty and science vs brainless personal greed. I wish we end up with something like «crime against the environment», and that international law is able to judge people or organization in this regard. Long way to go...

I got this link indirectly from a recent post by +Danie van der Merwe , a reliable, well informed and documented source who would benefit the WSJ and all of its readers if he was he editorialist. The rant is mine though, he usually only tells facts and provide material for thought: subscribe to him for a better world :)

I liked these little "tof" (time of flight) boards as super cheap lidar... but this application makes them even more attractive. I am unsure how long it would run before wearing out though :p
xLIDAR is a board that mounts some time-of-flight sensors to a turning disk in order to make a DIY LIDAR system.

[JRodrigo]’s xLIDAR project is one of those ideas that seemed so attractively workable that it went directly to a PCB prototype without doing much stopping along the way. The concept was to mount a trio of outward-facing VL53L0X distance sensors to a…

Interestingly the neverending issues with these clever 3D printer filement extruders at E3D eventually made the bondtech extruders closer to mass market. Before that either the latter were too costly, or they were almost ridiculously over engineered. Note to myself: issues with one should not change my mind on others :D
Still, after being hit by repeated issues with lots of 3D printer parts I tend to look either at high end stuff also... or super cheap and simple stuff (e.g. the 120€ Tronxy X1 with very little tweaks is weirdly enough for many jobs as a printer... I.e. jobs that require no insane quality nor speed, nor anything else than PLA...Yes it leaves much but at least this is a printer that never bothered me for the last 6 months or so! :D
4th e3d extruder completely destroyed due to bearing seized. This is ridiculous.
