ATTiny10 from Digikey (30 cents each, they were more expensive on eBay and Aliexpress), tiny piezo, some tiny button batteries, and a SOT23 breakout for one to experiment.

My plan is to sandwich the battery between piezo and ATTiny10, solder em all deadbug, use piece of paper on battery contact to keep it powered off until I am ready. The code will wait some minutes before making noise.

Pull paper tab, drop it in discreet places, walk away.
As long as the sound isn't TICKING and you don't have a BLUE, RED and WHITE wire looping around it.

Hi,
I bought one of these cheapo fitbit watches, $30.00.

Does pedometer, Kcal, heartrate, blood oxygenetc
And claims to do blood pressure.

It needed a smarty phone to talk to, and as I didn't have one, I offered to buy it for my step-daughter for her birthday, as she walks and jogs each day to keep her weight down and joints active due to Rheumatoid Arthritis.

I was intrigued as to how they measure blood pressure.
Well the watch like the other fitness thingyies only has the LED and sensor to detect  blood flow for heartrate and blood oxy.

This model needs the smarty phone bluetooth connection to get bloodpressure.
Well we set it up and it did after a about 30seconds give  believable levels.
She likes it because of the other stuff it shows.

My boss bought a $40.00 one  and it calculates blood pressure without the need of a smartyphone.

It turned up today and gave him reasonable pressure results.

He let me wear it and it said I was,  117/65. NOW I have high bloodpressure.
I'm on tablets, BUT they aren't that good.

I wore it to my doctor this afternoon to have a leg wound dressing changed.
Matt, my GP, was also intrigued as to how they get blood pressure.

So after my dressing was changed we did a comparison.
My REAL blood pressure   150/75, I know its high, but I'd just a had a painful dressing change.
The watch....  110/65... I checked it twice more and it was still around that point.

I lifted my arm over my head and it should have dropped, it didn't.

Watch... doesn't know what it is talking about. :o :o :o

Those two things may be connected :)

@Robin, we are pretty good at killing people. You got to give us that. #winning.

I will take a guess. 

The device does a look on the measured pulse rate against a static BMI table.  Leave it set to your mate's weight and height and you get RIRO.  A pre-existing condition might upset it too.

8 school shootings in the US in just the first 2 months of 2018.   :'(


This doesn't even happen in so called 3rd world countries.

No technical PMs.
The last thing you did is where you should start looking.

Really larryd....

"Primary school pupils were forced to lay on the ground in a straight line and were run over by tanks, and crushing them flat. Some of the primary school girls aged between 11 to 13 years were raped in front of their teacher and the teacher was later murdered by the government soldiers, possibly to conceal evidence of their heinous crimes," an independent observer said.

On 7 January 2015 at about 11:30 local time, two brothers, Saïd and Chérif Kouachi, forced their way into the offices of the French satirical weekly newspaper Charlie Hebdo in Paris. Armed with rifles and other weapons, they killed 12 people and injured 11 others

If only Americans would ban the commercial sale of firearms and ammunition (Venezuela 2012); and also institute a combination of gun buybacks and confiscations (Venezuela 2016), the country would better off ...
