  • Damn Shes got the latest LED flexilamp . How come I didn’t get one first.

  • You could send them a request perhaps to go in and delete a row . Maybe there is a PHANT command that will delete a row .Have you looked into that at all ?

  • Clicking on https://data.sparkfun.com/ give me an access error and I can’t get to see any data unless I use a tor browser so whats happening? Tried it with mozilla and Opera browsers .

    You have changed something recently and its stuffed it up Perhaps you are just censuring Australia or individuals out ? Hope not

  • Bit of wire in matchheads and connect 12 V and you have the same result. Ban all wire export -oh and matches too

  • Silicon Nitride Igniter - 12V In stock COM-11694

    So why? Whats so special about these that you can’t ship them overseas . A few bits of wire and some ceramic for gods sake . You Yanks carry on about nothing

  • I have put this post on ESP8266 Forum with full credits , In the Wiki page -Hope this is OK -email me if not I’m in your buyer database

    I put an LED on one of the GPIO pins and code it to flash 4 times on startup or continual on error which is OK unless you are short on pins . Is your code available? Mine is here for ESP8266 ESP12 board to Sparkfun data Thanks Jimbo

  • Use as said above like an LED on the DC side . Thats what it is!

  • I might add 240 Volts times square root of 2 equals 340 volts but the peak to peak is twice that or 679 Volts –80 volts over the rating?

  • So from https://en.wikipedia.org/wiki/Root_mean_square A similar analysis leads to the analogous equation for sinusoidal voltage:

    V_{\mathrm{RMS}} = {V_\mathrm{p} \over {\sqrt 2}}.

    Where IP represents the peak current and VP represents the peak voltage.

    Because of their usefulness in carrying out power calculations, listed voltages for power outlets, e.g. 120 V (USA) or 230 V (Europe), are almost always quoted in RMS values, and not peak values. Peak values can be calculated from RMS values from the above formula, which implies Vp = VRMS × √2, assuming the source is a pure sine wave. Thus the peak value of the mains voltage in the USA is about 120 × √2, or about 170 volts. The peak-to-peak voltage, being twice this, is about 340 volts. A similar calculation indicates that the peak-to-peak mains voltage in Europe is about 650 volts."

    So these are not good for 240 Volts like we have in Australia as the peak to peak voltage can be 650 Volts

    Will you comment then on who or what is right for RMS 240 Volts ?

  • What intrigues me is that moon planting and vine cutting supposedly give best results . Now if its so hard to sense these light levels electronically then what chance the plant even notices this . I’m working on the same area as you but I’m a bit behind you I think . If I get anything going I will post back here.

No public wish lists :(
