    Spectrum analyser Equalizer project how to go about it?

    For future design reference, an alternative way of doing this. I think this can be done in 8 chips total, only external passives would be LED current limit resistors, and a bypass cap or two per chip. On chip there are two dig filter channels, two SARs. In addition I created a 16 bit shift...

    Time for you to do some of your own homework : Google "voter suppression examples", starting with voting by mail (which Trumpeter does)..... And when you insist on government ID do you insure those infirmed, those with no car, those with jobs outside US (we have a ton of citizens in Saudi...

    Yes the right has a great record now of voter suppression measures for starters. Yes corporate right is totally transparent in their pollution, financial wizardry, worker safety, wealth transfer out of Corporate piggybanks (the wealth workers create) , oh so transparent. Would I call for...

    Huh, where be the well regulated Militia ? Did the founders mean all citizens carry a doomsday weapon ready to deploy and destroy the Earth at a moment of rage ? After all the RepuboCONs will argue until they are purple in the face they must meet comp on weapons accessibility, like AK47, 50...

    Lets see Fascist denier what we can agree on : 1) Less atmospheric acid rain is good, more is bad (to late with Maine Lakes already impacted) ? 2) Less chemicals in topsoil good, more is bad ? 3) Less traffic jams good, more are bad ? 4) More ice cream good, less is bad ? 5) More mining...

    Left POS, also get the sun rocket. But I would love to see the ratio of Right RepuboCON POS / Left POS, my direct observation in the thousands. Takes time but you betcha, theirs too. Get off your self absorbed piller and call the Australian Ambassador to US office and ask them how their ban...

    So you are pro Fascist I gather. Understand. I am Anti Fascist, just so you understand. I know you RepuboCONs support voter suppression, a fav of fascists, but we are onto your stuff like white on rice. So the Right and their RepuboCON PACS, "thus brainwashing the impressionable youth" Do us...

    Whats a progressive ? 1) I want no more plastic waste forming islands in the ocean 2) Massive tree planting program 3) No more corporate welfare 4) Any Right POS breaking the law put on a rocket headed for the sun. 5) Elections publicly funded 6) Water conservation and cleanup 7) Radioactive...

    @crutschow, I think much of the RepuboCONs, emphasis on the "CON", come from an environment where they think a few made all the wealth and have therefore the right to most of it. Observation having worked for a number of companies the workers create most of the wealth, and without them we would...

    How to connect this strain gauge?

    Notice how the Vref pin sets Vref to 2.5V and bottom of its 10K divider R is returned thru ground. Same ground as - supply of strain gauge ? Ignore the G R value in above pic. Excite - in above pic grounded. Excite + to +5 thru a 120 ohm R as discussed in #54 post. Also to get range out 0 - 5...

    How to connect this strain gauge?

    Notice Vout is 0 to +5, just right for Arduino running on 5V.

    How to connect this strain gauge?

    Do a simple test, no arduino, just module and a small V into module inputs : Replace above probe with your module inputs, and set its G to 10, and use the diamond tool to predict, for the Vref you have, what output should be, and compare that with what the test gives you. The V above is ~...

    How to connect this strain gauge?

    The module has output V that you connect to Arduino A/D. Simple insert a R in series with that connection. AD620 module output >> R >> Arduino A/D input pin. Regards, Dana.

    Got to admit, I skimmed over none of your rant. Wow, and I thought growing, rather than destroying trees, was, and is, a good thing. I know,, my town posted several million dollars bond to cleanup a PFAS generating business, in a town of just 30K. With cancer rates exceeding other towns...
