DIY Body Scanner Electronics

[Grimeaper]

If I went, and got a PHD in electronics engineering would I be able to understand, and do what you do?

Also would I be able to create my own gadgets?

I know it may sound stupid, but I want to get a PHD in electronics, and I was wondering what kind of skills would I have in the end?

You most likely won't reply considering the age of the video, but I will take any reply.

[MadMurphyGames]

Very well done, this explains perfectly.

[XTYNoLuck]

where did you get that tiny tiny crt tube...LOL i want to experiment things with that....please tell where i can find one of those.....

[jeriellsworth]

@XTYNoLuck It's from an old home video camera

[Pagweb]

I type "easy diy electronics" on youtube and I get this. WTF?

[derman077]

Be honest. Some geeky dude built you as a girl robot many years ago. Am I right ? lol

[mebossyounothing]

good job, i like it

[lifenexus]

Hey it is a great video.. My branch is Mechanical engineering but none the less, i enjoyed this one. well explained

[zolar7a]

That brought me back. I loved your explanation of how an analog video signal works. Back in the early 90's I built a video frame grabber for a class project...back then it was discrete TTL components for the Horiz/vertical counters and $300 for 64k of high speed static ram...I don't even remember what the A/D cost. The T/S 1000 was a nice touch too. Good stuff, keep it up!

[TechPro3]

Hi, Could you explain more about laptop Lcd Screens or L/S in general? For example how to understand pinouts, how make some use out of them - if laptop or digital camera's LCDs are lying around :)

Would be interesting - thank you!

[DragonForceF0REVER]

I'm not an EE, but I thoroughly enjoyed this video. It gave me a good insight into how CRTs work. I truly love the way you present your project with your lovely voice. Not a single dull moment. You should have your own show on Discovery Channel that would inspire more kids to get into EE.

[jeriellsworth]

@DragonForceF0REVER Thanks! I'm working at getting better each time.

[VanMedia]

@jeriellsworth do u know lady ada?

[jeriellsworth]

@VanMedia I do know LadyAda

[tjd1985]

You are so geeky it's hot.

[Ivultorky]

In 9 minutes you managed to put more useful information into my head than college did in a month.

[MarcLT1]

I see...

[technoshamanarchist]

Marry me...

[smoothntallGWM]

You are so great !! Thanks for creating and sharing this circuit.

[TheCrazyInventor]

Interesting video, always wanted to know more about VGA.

Love the EEVblog reference @ 2:24 :)

[jeriellsworth]

@TheCrazyInventor I should have said "It's all rubbish!"

[thepackrat]

@10mintwo I suspect that they would need to make a NEW chart ... or glue TWO of them together end to end !

[pieznice29]

Great video, your presentation technique is so easy to understand. Using the resisters to create negative and positive rails (from a virtual ground) from a single voltage supply is a so simple its amazing. Ill have to try that one day, im always stuck for negative voltages when im trying to use opamps and such, thanks!

[jeriellsworth]

@pieznice29 The resistor divider is ok in a pinch, but something in the commercial would most likely have a buffered virtual ground.

[myst32YT]

You have an amazing way of making me realize that i don't know anything... i just sit and scratch my head... ;-) Thanks!!

[jeriellsworth]

@myst32YT I feel the same about your chemistry videos, but I'm picking stuff up slowly. :D

[Films4You]

Jeriell advertising 'Sharpie Pens' again. LOL

2:25 Good Old Days, the 'Raster'. P.S. Very high voltage, thousands of volts

Great, interesting video's

[tharlowXY]

I couldn't keep up with most of that, but I still found it inspiring. I try to learn something new each day, and I think this video must have had something new for everyone! Anyway, for me I learned that A) you shouldn't let anyone touch your junk (because one day it may come in useful) and B) sometimes the best way to test if your junk is working is to use your hand. I was overwhelmed but then you said "And that's all it takes" and I thought I'll have to give this a try. Thank you for sharing!

[AmazGraz]

Amazing. You should see my grin : ^ D What? That looked like Basic. Amazing stuff. Weoo, if I have any ideas I'll do your e-mail. But smarter people than me are watching. I doubt that I can compete with their input. But you do make me think. And I might accidently get lucky and get to say something worthy.

[thoxbui]

I really just watch these videos because I like the feeling that I get when I realize that I'm a totally inadequate hacker.

[frakius]

You totally could have been a character on Northern Exposure. Didn't understand anything of this or any of your other videos I watched but enjoyed them. Made me feel like a kid again watching my Grandad make stuff and just been in awe.

[schoolmaster1945]

Nice presentation....I like the tiny CRT....I am working on an electrostatic version.....but the design uses no deflection coils of course...

[jeffreymhopkins]

I feel like such a nerd when I understand all of that.... a lot of your chemistry heavy projects I don't understand 100%, but this I do. Keep it up.

[the0rac]

... amazing ! :-) one day we should really consider to unify the drawing standards on this planet ;-) well some other standards too :o)

Greets from Switzerland ;-)

[gfxlonghorn]

Once again, you have managed to explain 3 or 4 concepts with completely different scopes with a level of clarity that all but one of my college professors could not match.

[xXcoolcubeXx]

why are you so damn smart

Where did you go to school, or is this all self taught?

[jeriellsworth]

@xXcoolcubeXx I'm self taught and a lot of help from mentors.

[10mintwo]

Fierce.

I'm just curious, have you ever had your IQ assessed? I understand that there are varying levels of acceptance as to its validity; but it would be interesting to know, 'cause I'd bet you'd be right off the charts.

[jeriellsworth]

@10mintwo I'm just stubborn. :)

[10mintwo]

@jeriellsworth The demurely clever answer I suspected you might give. ;o)

[jeriellsworth]

@origoangelohrol True the control grid will be more negative, but the interface at the VGA connector is positive in respect to brightness.

[chrisgj198]

Who is this Ben Heck? I thought that robot was for searching the passengers who opt-out.

[MrTechGuy1995]

Wait, You guys don't use CRT TV's anymore. Am I the Only one?

[nemoDaedalus]

Tiny CRT is so cute! :D

[RAYGproductions]

Good job.

[Albinorama]

Now, in slow motion please.

=)

[soulsearchingsun83]

Hey Jeri. You only used only one 9V battery, shouldn't you have around +-4.5V for the positive and negative rail? If you used two batteries, you could have used a center tap as ground. By the way, the capacitor on the negative rail is polarized wrong, isn't it?

[jeriellsworth]

@soulsearchingsun83 Yes! Good eye. In fact I needed this to stay between 0 - 5v for the ADC, so that's why I used 9v.

[8bitbubsy]

Jeri!!!

I still get nightmares from the bluetooth chicken, and I surely will after I saw that naked thingie you tried to glue on. *shivers*

Did I mention the bluetooth chicken?

[ntjbjhq]

Another example of why you rule Jeri! I'd like to see Ben H try making an x-ray scanner in less than a week using technology like you did! NEVER HAPPEN! ;)

But you're still cool Ben, just not AS cool ;)

[DanFrederiksen]

cute reference to the ben heck show : )

[thewii552]

i use a crt as a blocking monitor when I am making videos.;)

[rowey111]

awesome video! I wanted to see that baby CRT running though :P

[toyotaboyhatman]

hey, don't dog ben heck just because he's dirty about mounting things with hot glue, JB weld, and double sided tape :-)

[jeriellsworth]

@toyotaboyhatman I'm dogging him, because he doesn't use enough hot glue. :D

[nathanallan1]

I KNEW IT!

Evil robots are always powered by TIMEX SINCLAIR!! And Odyssey games, ALWAYS odyssey games!!!

:D

[vk2zay]

Love how you wrote a video basher in Verilog and built all the capture and glue hardware instead of just writing some code on the PC. My kind of engineer! :)

[sonicase]

josie maran product placement

[jeriellsworth]

@sonicase Josie is my new sponsor. Energy drinks are out and beauty products are in.

[doubleatheman]

This stuff is soo cool! yet so over my head :P

[jeriellsworth]

@doubleatheman My hack for tomorrow will not be this hardcore. It's going to be a good one.

[edabean007]

my missus said i can have one thing for xmas ... i'm going to ask for a jeri ellsworth.

looks like awesome value :D

[jeriellsworth]

@edabean007 Have you ever seen the movie Gremlins? I would seem like a good idea at first, but when you give me a soldering iron after midnight....

[XsavioR38]

That was awesome

"You could just plug it into your sound card but for the sake of rapid prototyping (roughly translated) I built my own . "

That was a great explanation on the CRT.

[jeriellsworth]

@XsavioR38 It would take me 10x longer trying to figure out how to program a PC to talk to a sound card. One of my super powers will never be "Windows Programmer"

[bobcat0]

I see the videogame 'cartridge' finally found a use. :)

[jeriellsworth]

@bobcat0 I need to find the rest of the video game system and 1-4 "cartridges".

[EEVblog]

Ben Heck is toast!

[jeriellsworth]

@EEVblog I'm eyeballing you next. Muhahaha

[illustriouschin]

Yup, this is definitely Pak technology, they never use computers when building their fantastic gizmos either.

[MoonBurgle]

I love the tiny CRT, so much personality.

[jeriellsworth]

@MoonBurgle I'm a sucker for collecting CRT's
