Hi, Melvin asked me on Twitter if it is possible to make a bracelet that removes the static electricity from body and avoids shock
Of course, there are these straps that ground the body and remove static electricity
But is it possible to make a cordless one?
And surely after I did a quick search, I found that there are these anti-static cordless bracelets like these
and my reaction was well, these are scam
I mean, how can you remove static electricity from your body without sending... put it in your pocket?
You have...how these things sell on the web?
under those people
How does it work?! It is...
See every time your body picks up static electricity say by walking with socks on the carpet
the only way to get rid of them is to take
Them and put them somewhere else like in the ground
and that's what this wire does
You can't just put those charges in a container and keep them in your pocket
Dave Jones from the channel "EEVblog" which is a great electronic
Teardown review and debunk channel has a great video about this and shows that these cordless bracelets are garbage
Basically, they've showed the fake bracelet. He got online contained only a single 1 mega. Ohm resistor in it.
And that's it
Wow, what's the use of that is holding a resistor in my hands supposed to magically discharge my body
It is very important to at least understand the tools you want to use for your work and educate yourself and not get scammed

Check it out. Anyway, holding a 1 mega. Ohm resister does nothing. Why even 1 Meg when you can hold this your own screwdriver?
Hmm that gives me an idea
I was wondering if it is possible at all to have a standalone
Bracelet that would dissipate charges and one thing came to mind
Which is one of those punk rock bracelets with a bunch of spikes on them
You might already know that electric charges accumulate on the sharp points in a conductor and so much charge in a time
Point results in them repelling each other hard and dissipate into the air and environment
You can easily see this when I run my Tesla coil
So I thought with those Punk bracelets having so many metal spikes
They potentially dissipate charges into the air quicker and drop my body voltage and reduce the risk of discharge and shock
So here's the plan. I'm gonna buy one of those bracelets and to test it
I'm going to charge myself using my vandegraaff and see if those spikes have any effect at all
Granville Street in downtown Vancouver is one of those streets you can find some questionable stores in.Hopefully I can find what I need there
Fantasy Factory eh? Let's check that jeez. That was the wrong shop. Let's check the rock shop
Hopefully this one has it. This looks like the right store. Oh
Oh,there we are
Those are the kind of spikes I'm looking for.What in a rest band. That's what is that it holder or something
I bought these two for a total of $70. That's a strange expense on my business card
Well, I got this not very impressive one row of spikes bracelet
But it's the pointiest one they had and then I found this one which is much point here. It's called a choker and
They both have metal exposed on the back to touch my skin. Okay, let's do it without the spikes first. I
Put my legs up
Cars my buddy a little bit and then discharged. Oh
That was painful, okay, let's do it the despites now, okay this time with the bracelets
One two three, four five and discharge
Absolutely, useless. Well, maybe the dome is charging my body too quickly. So let's do it more realistically I'm gonna touch that dose...ouch!
charge my body first and then let go and then touch the ground...ah s***
Hate surprises. Okay without the bracelet charging my body
One...two...three...four...five and discharged
One...two..three...four...five.And now with the bracelet
One...two...three...four...five x2
Useless
Maybe it's not making a good contact to my body due to my massive fare
So I'm gonna use aluminum foil to make sure that sparks are in good contact with each other and my body. Here we go
One,two,three,four,five and one, two, three, four, five...S***!...Useless!
F*** it,let's use the choker it's not gonna look good around your neck in the lab
So I'm gonna put it around my wrist with the foil around it for good contact
If this doesn't do it,nothing will here you go the SuperDuper anti-static bracelet
Ok 1 2 3 4 5 and 1 2 3 4 5...S***
What the hell?
1 2 3 4 5 ... 1 2 3 4 5 ... S***!
Completely useless I really thought this would do it
I really thought having spikes on your body should help but maybe their effect is insignificant
Compared to how your body already dissipates charges on its own now. Let's put on the
Grounding strap and see how well that works
One two three four five one two three...nothing
Even having my hand completely on the dole. I don't feel any discharge
Now instead of this strap I put my bare feet on the tiled ground
They given the non-conductive piles the charge better than those stupid fights, well, you know what,
It means if these spikes can't discharge you faster than your body's normal discharge rate
Then there is nothing out there that can discharge you cordless Li all those cordless anti-static straps are just a pile of junk
One note is that even in the corded straps? There is a one mega
ohm resistance in series with the grounding wire
You never want to directly connect your body to ground because in case you accidentally touch high-voltage you can easily get electrocuted
The 1 mega ohm limits the current and saves you while it's good enough to get rid of static charges
So make sure you have a properly grounded anti-static
wristband or risk killing your naked electronics and
