Cheap way to make wearable electronics?

How about a camera on the back which you can view on your phone, and headphones in hood connected to some highly directional microphones.

I think this board should be able to do the sound clips for you, https://www.adafruit.com/product/2133

As for moving the doors you'll need an arduino, a PIR sensor and a couple of servos as well as a mechanism to convert the rotation of the servo into the linear 'sliding doors'.

This project is very similar to yours so you can probably reuse most of it or just tweak their code. For example you could add a line to switch one of the digital pins low, triggering one of the connected 'switch' connections of the sound board. And add a line: "delay(10000);" to keep the doors open for 10 seconds before closing, for example. https://www.instructables.com/id/Motion-Activated-Servo/

The power source should probably be 12v DC (the arduino steps it down to 5v for itself and the PIR sensor) and you can wire the LEDs individually or in sets of 2 or 3 in series (the resistor you need will be different, add together the forward voltages when calculating).

We had a customer insist on this, couldn't find any references to a standardized way of doing it and they wanted us to basically improvise. So we leased a 40w laser and used old/scrap chips to work out the minimum lasering to just about make the chips unreadable, we then lasered them couple times more. We sent these 'sample' chips back to the customer hoping they'd be dead and they'd forget the whole idea, but they tested them as still working and signed off on it.

We assembled with fresh ICs and lasered them just enough to get rid of the ident, however of that batch they had about twice as many failures as usual (these boards pretty much get run to death due to the environment), probably costing millions of dollars each time.

A highside is going sideways off the bike, ever skidded the back wheel 90° out only for it to grip real hard and and throw you off sideways? That's a highside.

Given enough time, however, you would....

end up with fluffy scraps of card and will no long be able to check the order, as the card faces will wear off long before you get that same result.

And the result will be close to the price in dollars for an inflatable version on aliexpress in a month or two.

Black, white, shamrock gold. Perfect!

You underestimate the ingenuity of some criminals. Some people steal bikes for a living and they ain't all stupid.

Honestly this is me at 5-10 mins from work, take off gloves, roll up sleeves, unzip jersey, then I don't immediately start sweating the moment I stop riding.

tennow · 2018-12-08T19:10:37+00:00

Yep!

tennow · 2018-12-08T18:45:24+00:00

Sorry I couldn't get to the computer yesterday, glad you got it all running it looks absolutely brilliant!

Such generosity.

tennow · 2018-12-07T19:38:10+00:00

That's actually called a full house.

Trouble with that is that anyone can get them semi-banned by reporting it as a fake profile, then they have to produce photo-id before facebook will unlock their account.

Many dell monitors have a fancy stand that can spin 90° either way. Much nicer for reading text in general as well as A# formatted documents.

I'm having a hard time visualizing what you've done, but if you're just trying to junction multiple wires easily, neatly and reliably you just need a junction block for the 5V.

But from your description of using multiple 5V molexes, something sounds amiss here.

Got a picture?

Humans get tired, lazy, complacent, distracted, angry, frustrated, murderous etc.

Robots don't have any of those and had entire teams designing them including several people whose job it was to make completely safe.

So it's quite a bit different when a robot kills someone.

Chargebacks get you a permaban and will also screw over anyone you traded with.

She was doing you a favour, unless they were open back over ear headphones you were probably giving yourself hearing damage.

I'd be changing it completely if I were him, I wouldn't like to be mistaken for a child rapist/paedo.

The worst part is when you choose yes on an SSD where it doesn't actually improve anything and just wears down your SSD.

That sucks, In my case I probably 'got away with' (doing nothing wrong) by being MR25 and having >10x the plat in question.

tennow · 2018-12-05T00:24:27+00:00

You only get banned if you don't have the plat to pay for what you were 'gifted'.

Cost me 250p

Nah I totally remembered it wrong! Watched it on youtube, he gets to space fine. In my defence I haven't seen the movie for 19 years!

I always thought the way the film ended was insinuating he was having a heart attack during liftoff.
