Same here my friend!

Hi Mark, you seem to be missing 't' in line 5 of the second example.



Comment on Connector resistance matters: the Anet A8 PCB heated bed… by Mark

Fri, 26 Jan 2018 18:15:22 +0000

My multimeter (which is not the most accurate) shows that the extra resistance due to the connector might be in the 0.4 ohm range, but I don't entirely trust it. I was trying to figure out a more accurate way to measure it, but I may actually replace it before I figure out a better way. I want my printer up and running again. Feel free to point people at my blog in articles or blogs. That is, after all, what it is there for.

Very interesting article! And very interesting blog in general! I'm subscribing to your feeds. As far as I understand, you are concluding that you'll have to solder the cable directly to the main board to avoid the connector resistance, but is the actual connector resistance at dangerous values? have you measured it? P.S. I'm writing an article about the Anet A8 electronics and I would like to mention this article on mine, do I have your permission? Thank you



Comment on Interactive Programming… in C by Chris

I've found this technique useful for rapid development of audio generation software on Linux. One thing that caught me out was differences in the way that different compilers save object files. I recall that one compiler (either Clang or gcc) appeared to save the compiled file in two stages (saving a header first, then appending executable data at a later stage, perhaps), which confused the monitoring part of the code when it tried to load an incomplete library.



Comment on SSD1306 drivers for the ESP-IDF framework… by Ben

Thanks for the links! The first one worked on my ESP32 to at least emit a Hello World, although the display had some corruption until I added external pull-up resistors, as noted in the readme. I've found the ESP-IDF framework reasonably easy to work with, while it's not quite as easy as Arduino for rapid development, it's as good as any other embedded framework I've worked with, and easy to recover from a bad flash.

The Arduino port of the ESP32 framework is also supported by U8g2 directly. Just install U8g2 via library manager.



Comment on An inexpensive, open source, two factor authentication USB token: the U2F Zero by Mark VandeWettering

Yes, you would be locked out, although in the plugin allows you to specify secondary verification methods as well. It's also possible to disable the plugin if you have access to the web directory.

What happens if you lose it? Are you now locked out??

Looking forward to seeing more posts about interesting things!

I'll try to get them back online shortly.

I am glad many others were able to gain from your knowledge through Quora :) But it will be nice to read what you're up to!

As far as I have tested, none of these are operational. Which is a shame as they look interesting. Any chance of getting them up again please?



Comment on Some new addition to the brainwagon labs… by Bob

Glad to see a new post. I've been checking about once a week and wondered what happened. I especially like your ham radio posts. On the other hand I've just begun playing with 3D printing, too, with a Monoprice select mini. I'm also trying to teach myself fusion360 so I can make enclosures for my projects.
