  • Picture of your messy workbench makes for a very personalized profile background

    03/05/2016 at 21:20 15 comments

    I feel that not a lot of people are taking advantage of the profile background feature, probably because they don't know what to put there. So the other day I thought that since a desk or workbench usually is pretty wide a picture of it would be great for that, plus it's very personalized/individual/unique.

    On my profile you can see my mess (that I might change from time to time), now show me yours! :)

  • An EE's Christmas cookies

    Inspired by some other non Christmas themed cookies my family made I was struck with an idea...

    A spare/unused one of these:

  • Virtual serial port tunnel (to use with ESP-Link)

    10/27/2015 at 00:12 3 comments

    Inspired by #ESPecially Easy AVR Programming I started playing around with ESP-Link a bit. As mentioned in the readme you can point some programs (e.g. Avrdude, PuTTY) directly at the ESP8266's telnet socket but as far as I can tell most others (e.g. Termite, Arduino, ESPlorer) will only work with serial ports. Therefore a tunnel from a virtual serial port to the ESP's telnet port is required.

    Some quick googling revealed com0com/com2tcp and socat should accomplish just that on Windows and Linux, respectively. It wasn't immediately obvious to me how to set up com0com so I made a detour over this other program also called COM2TCP. It was really easy to set up and worked right out of the box but unfortunately free usage is limited to 45 days so I went back and decided to figure out com0com.

Thanks for your interest in my #LiFePO4wered/Pi project!  It has since been superseded by the #LiFePO4wered/Pi+ so you may want to check that one out as well. :)

Haha, I was just looking at your profile and about to write pretty much the same thing ;)

Thanks for the follow, Stefan!

I love your breadboard widgets and your dev kit!

Stefan Lochbrunner wrote 09/15/2015 at 19:33 point

Thanks! So you see your project #Pi/Arduino Prototyping is right up my alley ;)

I'm looking forward to seeing how it turns out!

Are you sure? yes | no

Craig Hissett wrote 09/15/2015 at 19:42 point

We have very similar tastes then :-)

If i get my project up and running it is going to make my life soooo much easier ha ha.

If you have any ideas feel free to contribute :-)

Howdy! Thanks for the follow!

Stefan Lochbrunner wrote 09/05/2015 at 15:51 point

You're welcome! I'm very interested to see what your project turns into since I'm working on a CNC machine as well :)

Are you sure? yes | no

Me too, Thanks :)

Woot! Thanks for the new follow, too!

The CNC-thing has been backburnered for a bit, but it's definitely still running through my brain. How's yours coming?

Are you sure? yes | no

Eric Hertz wrote 10/24/2015 at 22:46 point

And another! Muchas Gracias!

Are you sure? yes | no

Stefan Lochbrunner wrote 11/05/2015 at 14:43 point

Again, you're welcome for the follows. I hope you don't mind but I'm hesitant to skull until some proof of concept or in your case until I have time to read through the whole thing ;) 

Oh no! Put anything on hold but not #CD/DVD mechanisms and cartesian thinggie[s?]! ;P This is a good reminder though, I meant to skull it for the secret side project alone, it's just ingenious! I'm heading over there right now!

Mine has been on hold for a while, not being able to fabricate the parts precise enough was just so frustrating (even though I tried to compensate for imprecise fabrication by adding lots of adjustment options). I'm, too, always thinking about it though. Not having finished it is bad enough but now I'm even thinking about yet another CNC project ;)

Are you sure? yes | no

Eric Hertz wrote 11/06/2015 at 00:17 point

Oh the ol' skull-debate... Skulls say more about the giver than the skulled-project ;) Yeah, there's [quite] a bit of rambling on my projects... Rather'n skulls, I want a four-page book-report on what my reader has learned, on my desk, 5:30AM!

Yeah, CNC-stuff is difficult when it comes to the mechanics. I hear that! You could start a project-page about the unfinished CNC project[s], ideas, and the processes therein... I would be interested to see it!

Are you sure? yes | no

Stefan Lochbrunner wrote 11/06/2015 at 11:02 point

Luckily you didn't specify a date or timezone that time applies to so I'll take my time. How much of the final grade is the report going to be anyway? ;)

I don't think it's so much rambling but a very detailed thought process which is interesting, too. But maybe they're the same thing...

As I was writing that last comment I was thinking about making a project page which would probably serve as a source of motivation as well. Fair warning though, I have a 22 page pdf of handwritten (actually it's mostly drawings) ideas! Although to you that's not much of a threat ;)

Are you sure? yes | no

Eric Hertz wrote 11/06/2015 at 18:48 point

You only think you're lucky about the lack of date/timezone, but I do believe it's customary to assume the timezone of the speaker, and the date, if unmentioned, in the context of a time, therefore assumed to be that day. So, you've unfortunately failed... On the plus-side, you needn't bother taking the final, so can go skipping in fields or whatever it is you "students" do with your free time :)


Hah! If you've already PDFed your drawings, then yeah put 'em up! 

But wait until after the final, lest I consider it a decent make-up for missing the book-report... I've already promised you free-time, wouldn't want to take that away on account of your ambition!

Are you sure? yes | no

Stefan Lochbrunner wrote 11/09/2015 at 13:06 point

Sorry for the late reply, but I was too busy over the weekend skipping in fields and stuff.

I would agree that it's customary to assume the speakers point of reference but here on my profile I make the rules. Therefore, I'll probably do some more skipping in the fields before handing in my report :P

Let me do some* more procrastinating and I'll get started on documenting my CNC efforts soon-ish**.

*a LOT

**in the distant future

Are you sure? yes | no

LOL Hope you enjoy the field-skipping!
