@moose4621 @ashthespy I found the problem that was confusing me .. turns out I was reading the wrong filename fromspiffs for my .js aaargh LOL go figure...So I have my string coming through in the payload and printf shows the line as I need and want it : value,value,value, etc. Now I just need to know how to save the payload data as a line in SPIFFS ... I currently can write or append to a file on spiffs but can't get the Variable type correct :-(
has anyone played around with small servos? why do they jitter so much when i try to drive them from the ESP?
@skorokithakis Hi .. sorry man I can't help there .. but maybe too much current drain ? maybe not sustained current ?
@skorokithakis Just a thought
I don't think so, it just jitters while sitting there
thanks though
maybe its noise ? Perhaps feedback ? try pop a low drop diode into feed for servo ?
maybe a snubber circuit needed ?
I have in the past found that as an issue when driving mechanical relays ( they have a coli too) inductive load
i'll try mitigating that, thanks
esp8266/Arduino#4296
Try check the noise with a scope or drive from 12V (or other) battery
I think I figured it out, because it's software PWM, the noise is crazy when you're connected to wiofi
wifi*
i'll try the ESP32, it might work better
or do you mean on the ESP power rail?
i think the timings are off because of the interrupts
supply > electrolytic cap > regulator > electrolytic cap > cermaic/polyerster/tantalum (not sure which type) the little blue ones worked well often for me on NRF24L01+
and if i was driving relays I would pop in a tranny (bc547 or simlar) and a diode (and or snubber ( snubber good if you're driving inductive load especially from MOC or similar)
even if wemos have there may not be enough filtering
doesnt hurt when testing to pop a few extra in and scope the signal
i don't have a scope though :/
just pop this string into google
snubber cirucit for inductive load servo
snubber cirucit for inductive load servo
now would you like to get blown away ?
LOL look here
that's amazing
i made a site for people to share projects on: https://www.makerfol.io/
but nobody wanted to :/
wellstart rounding up the peeps here .. we could always do GROUP PROJECTS too
But maybe for you this might be faster :- https://hackaday.com/2015/11/04/one-dollar-usb-sound-card-turned-o-scope/
that's nice, but that keychain dEEbugger is super sexy
indeed awesome and very cute device that one
@skorokithakis you can even create one for your mobile
pop this into google >> phone oscilloscope
dude have done it for less than 3 USD ..
lol
have you worked with the esp32 at all?
@skorokithakis No not yet ... been holding back until price drops and hopefully will be able to port code over when I finally get one
@skorokithakis dunno haven't actually even checked :-( ...
no analogWrite, though, so it must still be immature :/
@skorokithakis Dude I gotta get to sleep hahah its 4am here .. chat tomorrow buddy .. sleep well ..5am in greece ..? Insomnia ?
goodnight!
So I have a wemos D1 mini that I am using for remote water tank level sensing via the thingspeak IOT. I send the esp into deepsleep for 1 hour then wake, turn on a ping sensor and take a reading, measure the battery voltage and then connect to the network and send the readings to thingspeak. My issue is that after about two days it fails to go into deepsleep and sends the battery flat. I have a "deepsleep on fail to connect to wifi" routine in the sketch.
@moose4621 the code looks solid the battery dying seems like a problem. I would attach a deep cycle cell battery with a solar plane onto it, this way you can always have power be replenish on your downtime/ deep-sleep periods
@Allwaysawake Thanks for your reply. I probably should have added that it has a 800mah lipo and a solar panel attached.
@Allwaysawake When it is running I can see the battery hitting full charge by about midday everyday and then, crash with no more readings.
Um, 5watt 6v I think?
@Allwaysawake I also have the wemos battery shield attached with built in charger but I removed the leds which accounted for most of the power drain.
@Allwaysawake I see the battery voltage hits 4.2v at midday and by early morning it is about 4.05 to 4.1v just before the sun comes up.
monitor available heap after each time the readings are reported out
there are known issues in core 2.4.1 about heap, and of course axtls can cause some trouble, so try latest git and, if you can, switch to bearssl, it's much more stable vs. axtls
Hi all
whats news ?
@denman0000_gitlab How are you getting on with your project?
@moose4621 re msg @ 16.19 I would havppy to test that on a standalone esp-12f which I have
@denman0000_gitlab Where are you getting the message numbers from? I cannot see any.
@moose4621 I think I am on track now with project ... I need to figure out how to carve up payload array into the variables I need on receive (Sprintf, sscanf)

Yay re Friday indeed :-)
TGIF woop woop
T-minus ....
@moose4621 looking at time stamp on right hand side of each message ( I'm logged on using notebook and firefox
@denman0000_gitlab You are welcome to play with the code as you see fit. :+1: I have only tried it on one D1 mini so it would be good to try it on something else.
@moose4621 will need resistor divider values and ADC port number i'm guessing
did you see link I sent to Stravros earlier in convo here ( scroll up if you can ;-))
@moose4621 see here re battery monitoring .. problem is it's in LUA code ( I can't fathom)
@denman0000_gitlab The Wemos D1 mini has a built in voltage divider which I added to but the voltage range is 4.2 - 0. There is only one analog pin on the esp12 isn't there?
https://www.youtube.com/watch?v=okP4a6NrhlQ this was something I sent Stavros in the early hours :-)
@denman0000_gitlab Awesome. I scrolled back through yesterday and saw that.
@moose4621 yes re ADC pin :-) One is fine I think .. will have to come up with an ingenious way to make the probe pin hop between batteries
Maybe transistor gates ...hmmmm
multiplex one ADC pin
@denman0000_gitlab This is my contribution to the oscilloscope range.

https://www.thingiverse.com/thing:2211231
@denman0000_gitlab Why swap between batteries? Total voltage would be fine.
have you tried it with the app mentioned in the video
might be 100% compatible out of the box ;-)
May I order one :-)
did you get any orders ?
or I can just pay you as thought I'm ordering one to make it official and will etch and askk for advice
Well get busy testing already :-)
@moose4621 No sadly not
I saw your box for that look 3D-printer-ish .. am I right ?
@denman0000_gitlab I have not attempted to sell any. Thingyverse is a file sharing site so others can make your project.
@denman0000_gitlab Yes, 3d printed. All the files are up there.
@moose4621 havent ever ventured down the 3D printer avenue as yet .. Time , time , time ..sigh
Dig the Sine wave concept :-)
that little scope must be great for small signal stuff
@denman0000_gitlab I cannot justify life without one now. An absolute necessity.
@moose4621 Wow ..that good ? Gone of they days of building boards to enclosure size hey ? :-)
Haha yes and apparently maybe a grrek too (Stavros)
@moose4621 Did you build your own 3d printer ?
@denman0000_gitlab Check out some of my other stuff on there.

@denman0000_gitlab My first was a chinese kit that was completely in pieces. The second one I made from scratch based on the first.
I run both printers a lot!
@denman0000_gitlab Is that message number based on your local time stamp by any chance?
@moose4621 re message and timestamp ...GUILTY AS CHARGED !!
:-)
@moose4621 that is a very interesting page .. thanks for sharing .. Interesting about the cow RFID tag .. as it happens I am presenting tomorrow on this https://www.youtube.com/watch?v=LrvNC2glTQg
heres another (shorter in case you haven't the time) https://www.youtube.com/watch?v=MA2ZaM3Oyas
@moose4621 now a quick question re my code .. First of all thanks for all the help, tips and chats so far .. been awesome
@denman0000_gitlab That's awesome. What is your involvement?
@moose4621 this is the payload message I build-up and using content.send on TX side and receive on RX side :
get Text: *test,home,2018-06-12 12:00,1528797600,2018-06-14 12:00,1528970400,Normal,0001,001

@moose4621 I want to pop that in VAR's starting after the * eg.
char devname, char location, byte month, byte day, byte hour,byte second ..etc
if you have a quick way I'd appreciate it .. I was thinking SPRINTF and SSCANF

@moose4621 I'm a trainer .. main topic virtualization ( 11 years specializing in virtualization (vmware) , year 18 computer training)
@moose4621 Awesome re water tank level sensor .. you should add a ph tester to it too :-) UPS for hydroponics then ;-)

I am looking at this now.
@denman0000_gitlab I have a Aquaponics farm if that counts.
@moose4621 and that land curiser center console .. wow and the other stuff too .. sitting here gawking ! well done man
@moose4621 Negative re array ... In arduino and NRF and 433MHZ days it was sent as array
I just collect it all on webpage as a javascript VAR now and then content send
well I'm guessing its all TEXT on webpage side
its all on the esp
@moose4621 PS .. also on a 5,8 GHZ link .. 4,8 KMS ubiquity M5 bullets and 23Gig dishes either side
