An interestinf setup!This "Mpemba" effect has been reported for some time - I do not understand why a known experiment is named after this person... I think that the old Greeks mentioned it as well.
@ArmtronixI would be a real help if you could revamp the article to reflect the changes mentioned by WalterE18.One question though - can one use one RPi as the Broker AND be able to publish+suscribe as well. The setup being 4 Rpis One as broker that also collects data and three RPis that just collect and publish+subscribe data.
@ARMTRONIXI agrre with WalterE18 - It would be great if the Artikle could be revamped to reflect the latest changes.
BrickPi3 BalanceBot – A Segway With the Raspberry Pi
19.2.2017May I suggest puting the source + construction info in GIT?BD
I was shown that 50 Years ago when i was 18.
Your reply seems rather gramatically challanged. I suggest taking an English course.
um, sorry old boy, hardly understood any of that.....
Needs a much longer delay to switch off - make it a bit more fun.
That should be a must...otherwise too much current flows from the GPIO.
Hello,I think one ought to use a 330 Resistor on each LED to limit current.
Very good!. Perhaps an addendum for a publisher and Subscriber. I assume that one can create a rpi with publish and subscribe at the same time?
Right, I think that is really enough!
Interesting! .....I think I'll re-do this project on a Raspberry Pi 2 (or 3). The Rpi 2/3 are powerful enough for advanced processing that the Arduino cannot match.Perhaps using an Arduino an IO board...
16.4.2016That would be super. Since this is your excellent project, I'll wait until your RPi project is finished. Please let me know when, if possible.NT
Very good.....but how about a Raspberry Pi 2 or 3 Version?
14.4.2016A good and interesting Project. Where does one get the sensors? (prerably with an EU Distributor)
Good and worth trying out, but why no vinegar?
sorry. but no. The keywords are "fraudulently alter" ie changing stamped value The other words deface, mutilate, impair, diminish stand on their own. But I read that Museums etc offer Penny Crusher service obviously all is OK.
@lairdkeffer: If what Landroo has written is correct, then you are very wrong.It does clearly state defacing... etc is illegal.Note that falsify is an extra word .But I doubt if that black helicopters and men absailing down to the lairdkeffer household is a threat....
