and yeah, there are many who's willing do die for science.

Though I'm not one of them... yet. (It'd be kinda nice if I died for science in my 80's or 90's)


For Science!

Ok, I thought I was a mad scientist highschool student, but you sir take the cake. You get mad props from me, since I'm a Junior physics undergrad right now, and you've far exceeded my skill level. Keep at it, work methodically, expect the unexpected, and I see no reason why you can't pull this off

Yep, On-hold until I finish Custom-fi 2.
I have the components to build the HV amp.

LOL

 

So what did you do in your highschool days?

Very interesting thread. Any updates on these?

This project is currently on-hold until I finish my Custom IEM build...

Which is also on-hold because of my school work.

So not yet, sorry about that~

 

I'd expect to get back to this project by christmas holidays.

Just a little bit of basic robotics stuff with arduino,nothing this intense, so hat's off to you!

Hm... i"ve never used arduino before, but always hear people talk about it.

It's like a development board with an Atmel AVR µC right?

 

I've done a bit of assembly programming for the AVR and MCS-51 instruction sets before.

Just some really simple embedded systems, mainly for controlling controlling a power amp.

(Soft-start, Output delay, Muting, Input select, etc)

I really like the AVR µC's ISP (In-System Programming) and Internal ADC for analog inputs, it makes all the MCS-51 µC's look stupid lol

Hey, I've been working on a similar project.  I've been having issues with the flybacks I was using to power it.  Waiting on new ones...

Got a construction log??

Flybacks? Their voltages are too high, and it's hard to get a good DC out of them.

(they only have a half-wave rectifier inside and no smoothing cap -> bumpy DC)

 

Well at least that's why I decided to go with a multiplier, have any luck with them?

A flyback can make any voltage (it is a topology, not a specific power supply), and you can add a capacitor to their output to make it DC.

 

Unless you're talking about a flyback transformer from a television (a term which has led to terrible terminology misuse in the hobbyist community). That would likely be the wrong tool for the job.

Oops, I read FBT back there. :P
Now that would make more sense if it was flyback converter!

 

but if you use a flyback to step high up you'd need a HV transformer right? 

(which is not easy to get ahold of.)

I've had luck with them, but not these particular ones. Sorry no construction log, it has been an off and on project for about a year.

Nah, computer monitor type. You just have to test for the correct pins. Or, in the case of the ones I ordered I have the schematics.

No just a plain flyback will work.

So long as the windings don't arc over, any turns ratio will work in a flyback (at least in an ideal case). There are ideal turns ratios that can be calculated, though.
