691  Community / Bar Sport / if any circuit emulator programmers pass by.. . on: December 15, 2013, 05:09:13 am
I'd love to see the next level of evolution....

How I hear you ask! Let's interface the phone sensors smiley  we could feed in analog values like accelerometer or compass and other similar sensors...

Then in circuit emulation feed the speaker into a circuit to create fuzz , feed in light sensor as an ldr, detecting light etc, but have it all emulated as a circuit doing the real thing!

Creating your own circuits to interact with phone sensors, transitors causing clipping if not correctly biased so without even being near a breadboard you get to experience the real thing emulated smiley

The reason for using 3 leds in series is so that you can power all 3 from  a single resistor basically, thats how the 12v strips work anyway ..

That and it's easier than individually soldering them all with their own resistors.

This would work (Company is in Calgary).  Drive it with a transistor and use a snubbing diode across the coil:

This is another option, would require re-think of the design though:

A snubbing diode? (Resistor + capacitor)

Look, being constrained by the hardware limitations means we're not going to see huge programs....

But let's suppose your sketch goes out into the wild and someone merges code and at the end of it fails because the person forgot to copy the pullup  into his/her setup ()

But you're right... probably wont cost you time to fix it if you know what you'rd doing...

(This could all have been avoided with a 4cents resistor lol)

So nobody here has ever mistakes happen? Code vanishing?

Maybe because you used a backup, mouse / keyboard go mad accidentally deleting code, I'm not saying it will happen but it soundslike you've not been knee deep in code looking at tens of thousands if not hundreds of thousands of lines of code some of the desktop apps I've written over the past 15 years ..

But a 10k resistor to high is not that much of a deal to ensure it works properly despite of code used.

While I agree Paul, I think it could be solved using the method I said... so by tricking every supplier, dealer out there into signing up... come February you  then take every contact signed up and then raid and take out almost every dealer out there...

How effective would this be... I guess it would be a matter of time and just waiting ..... .

I just know it would fail because the amount of money that's made from illegal drugs... unconstitutional,  honey trap, illegal - whatever you call it, entrapment even telling people to sign up for a license to deal...

1-2 months later the police target the list, even if 80 percent are caught it would have a huge impact on crime.

Do law enforcement agencies and police really want to end it?

I'm not convinced they do!  For example,  if the police/DEA government simply issued out tv adverts, posters, billboard etc.... saying "deal drugs legally with a license"

Phone number at the bottom, website...

You have until say jan 29th 2014 to submit your application, name, phone number, etc...


How many people who deal would sign up?


(Drug war over, every dealer out there just got caught)

You're thinking about it all wrong. Legalizing drugs would help drug dealers about as much as Wal-mart moving into a town helped local mom-and-pop stores. The drug dealers will get put out of business by big drug companies that have the ability to mass produce drugs, negotiate for lower license fees, ensure product quality, and distribute product globally.

In the end, the consumers win. Drug users get cheaper and better drugs, the government gets more tax money that it can waste on bull****, and the police get a month off while the criminals find the next get-rich quick enterprise now that selling drugs is unprofitable.

Who said anything about making it legal?

I have one argument....

Using a resistor ensures it's pulled up, what happens when you accidentally remove the pullup or switch states accidentally and you then spend hours debugging to find it....

You may as well say you want a cake but you don't want to use all the ingredients to make it properly ...

Your code in your last example works ... but it's not a good way, 2 for loops would save memory and your fingers....


Look up for loops, if , basic logic statements.... walk before you can run...
702  Using Arduino / General Electronics / Re: TX RX pins lighting LED problem on: December 09, 2013, 02:24:26 am
you'd need to do hardware modifications to stop those pins.... (lifting the USB to TTL chip from the board for example)
703  Community / Bar Sport / Re: .HEX Online store? on: December 09, 2013, 01:27:15 am
Bugger...

If pins were somehow able to by dynamically assigned somehow (I thought a script but you'd also have to upload it to the board with it)

shame....
704  Community / Bar Sport / .HEX Online store? on: December 09, 2013, 01:12:15 am
Is it feasible?

Instead of browsing Apps, we browse .HEX files and each hex and a little description of which pins to use (what goes where) press a button and the program gets automatically downloaded and then uploaded (seamlessly) ...

is AVRDude standalone?  (IE, copy the exe and nothing else) if so, avrdude could be used as a resource file ....
705  Community / Bar Sport / Re: So.....Decorating stuff with Arduino's THIS HOLIDAY!? on: December 09, 2013, 01:01:30 am
I've never got used to "Summer" down under.

I've been in this country now (Australia) for 12/13 years, and yet every year come Dec, it's warmer, brighter, sunny  and even though your brain knows this, it's still an odd feeling because you associate summer time with summer, not winter and certainly not christmas, you spend the cold months being miserable here then you're looking forward to summer... not Christmas..

it's all a little weird ....

People from the northern side of the world use Christmas as an excuse to cuddle up, next to a fire, keep warm drink the cherry, brandy, go outside to keep your beer cold in -8c so a lot of the enjoyment for christmas (for me at least) is time you get off from work, so you don't have to get up in miserable cold weather, take a break enjoy christmas.....

Since everyone's loving summer (when xmas hits) and getting over the winter spell into warm weather, all that ambiance is gone... on the other hand if you love to party, get drunk and walk around in shorts for christmas, then yeah you'd love it..

But for me, unless it's cold and maybe snowing, I just can't fully get into the spirit of xmas.
