Here is a test picture from this computer--
Hi Lidmotor,

An oversized picture causes the text to widen automatically in a post too but only in case you do not use
carriage return (Enter) after ,say, 7-8 words, this will make the text a column-like format.  So whenever you
make a post in a thread which is already too wide by a high resolution picture, then you can make it easily
readable by reediting your text to a narrower series of lines, all this within 12 hours after the posting time.

This forum software sucks in this respect and Stefan Hartmann should resolve such issues now that he is going to
change the forum software he has been postponing for ages now...

The Tesla picture you have uploaded to test one of your computers is ok by size because it has pixel number of
512x655 and the 512 number (the horizontal pixel number) can go as high as about 900 with the present forum
software without causing thread widening.

If you open a picture in an editor like Paint (built into Windows) before uploading to your post, you can see the
number of pixels in the very bottom line in the editor and using the Resize feature you can adjust it.As Slider
mentioned above, the width and resolution of one's PC monitor also counts in a certain extend but generally
many forum members 'suffer' when a too wide picture is attached to a post in a thread.

Oh and just to explain my posts following the supersized pic...yes I too hit enter after several words, as Gyula mentioned.
For all pics, I open them in GIMP, resize to a width of 640 and save out again. Am running Linux Mint.
Can Peter over at Overunityresearch be approached to share his code ? because the forums have a very similar layout. Both seem to be using code from Simple Machines. Over there, each pic is a large thumbnail that can be clicked for larger.


Here's where the sig gen is up to. Am wiring it up now. At some point it'll get a case :)

Gyula and Slider---Thanks for the help on the post size issue.  I will get there but it takes me awhile to learn certain things.

-- Lidmotor

P.S.-- Slider that little signal generator looks really cool!  I hope it works.  If it does I guess my next project might be that one.  I can team it up with my old computer O scope and maybe get something meaningful done.

If you're not used to editing pics then it can seem a bit daunting. It really isn't a trauma, after the first couple of times. Oh, your camera may have resolution and size settings, which may be in the menu's if it's a phone.   


The build has been interesting, shall we say.
It's comprised of the AD9850 module, an Arduino, a screen and a rotary encoder. The bits laid out well on the perfboard.
Schematic that has been followed is here:
http://arduinotehniq.blogspot.com/2015/03/signal-generator-with-ad98509-and.html

I soldered everything up and plugged in the USB cable.
Smoke escaped from the Arduino diode !!!!
It wasn't just a whimpish puff of a slow fail either, the damn thing went off like it meant to fail properly !
I disconnected power to the screen and AD9850, then connected directly to the +5V and GND of the Arduino....life.
So then I connected the screen, it came on fine and showed the code running.
Twiddling the encoder works fine, values go up and down and the push button bit works fine too. As you can see in the image below, it was set readily to 13.6MHz (I had also changed the code because it had said 'Mhz' originally).
But connecting the VCC of the AD9850 powers everything off. That shorting condition will have blown the diode under the Arduino.

Am now going to power the AD9850 on its own and see if the red power LED comes on.

Edit: ok, i just finished winding the new magnet wire coil, it is bifilar 24awg. magnet wire, strands are in parallel at 300 milliohms and 31 grams weight, which includes a little electrical tape, that is used to tighten the windings together.
Hi SkyWatcher,

Okay, so the paralleled wires now give 0.3 Ohm DC resistance for the primary air coil. This means the dissipated loss in the primary will certainly be less than earlier for the 0.69 Ohm (calculated by me) single wire winding, considering similar collector current.

Here I have to tell you I made a calculation mistake for the dissipated power for the single wire primary coil in my post #239 where I got a rather high loss at the 11.2 mA collector current: this was only 0.0912 (and not 91.2) mW, sorry for the mistake, I rang the alarm unfounded.   :o

Because you have increased since then the supply voltage to 16 V and the collector current was 21 mA, the loss for the single wire primary may have been 0.0212 * 0.69 = 0.304 mW. If you now keep the supply voltage and current the same for the paralleled two wires in the new primary coil, then the dissipated loss in the paralleled wires would be 0.0212 * 0.3 = 0.132 mW only.

So all these mean that such low primary coil dissipation is negligble versus your earlier 336 mW total input power (for the single wire primary coil case).  Probably you will not see much improvement in brightness with the paralleled wire primary coil versus the single wire one, provided you insure identical input power for both.

Hi Slider,

Re on your picture size 640 you use here: as long as this forum software is not changed to a better one, you can bravely increase horizontal size up to 900 if it shows some picture details better. Alternatively, you can cut the picture edges on the left and right sides when there is not meaningful detail at those areas, this can also reduce the horizontal picture size.

Good progress on your SG build, and hopefully the AD9850 chip did not get damaged.

I may try some of that bravery hehe
900 it is :)

The AD9850 has been tried on its own, on a breadboard, with an LED on the power rails to denote power. Every combination of VCC and GND, be it both or just single VCC and GND produces the shorting out.
Here's an Unlisted video that demonstrates what's going on.

I've contacted the seller via Amazon, requesting a replacement module.

Hi all. is any replacement for PN4248 transistor ? I want to make my own Slayer Exciter circuit but PN4248 not available in my country

thanks

Hi Erfandl,
If you wish to use also a pnp type replacement,  then out of the many types there is the 2N3906 which may be available for you. These are the data sheets for it, many manufacturers produce it:
http://www.datasheetcatalog.com/datasheets_pdf/2/N/3/9/2N3906.shtml  If you have  RS Components, Mouser, Digikey, Futurlec or similar vendors, then I can look up some more types for you from the available offers. The PN4248 is a general purpose, low noise audio transistor, the latter feature is not needed here. There are two parameters that need attention for a substitute type: low saturation collector-emitter voltage and a decent hFE of 100 or higher and perhaps you can find such locally.

Hi Slider,

That is the best that can be done, unfortunately.

Even if someone starts looking for a faulty component by say carefully removing a tantalum chip capacitor which is across Vcc or lifting up the 4 positive supply pins for the AD9850 one by one, etc  the result may reveal the problem but the soldering may remain visible on the PCB and would just jeopardise any board replacement immediately.

thanks Gyula I found 2N3906 in my area  8)

2N3906's are decent workhorses for PNP.
2SA733 are good and plentiful too.


The seller, HiLetgo, got back to me saying they are sorry.
Also to recontact if there is still a problem (?)
Does anyone know how to re-contact sellers on Amazon ?
Update - found a way to contact and have done so.

Many thanks Itsu,
It should be ok from now, i've just luckily not had to do the runaround emails thing before on Amazon. They seem fine, but understandably guarded about fake claims.

When Doctor Stiffler said  "What does mass have to do with it ? "
He was dealing with less experienced persons doing the series resonance experiment.
He meant that the experimenters should use a large plate capacitor (aluminum blocks)
instead of the small pico farad component. Increase of surface area.

The tiny signal generator boards are the same it is difficult to remove the vhf zig zag.
One board kk moon MHS 5200A was big enough to get in and remove the noise. Distributor=Hiletgo.
Also upgrading the final op amp brought the SG to a descent quality. The reinvented wheel.
Increase the surface area, in this case with a congested board. Cut the trace and mount modification up.
Requires precision skill, a microsope and steady hand. The lightning on the sine wave is another example how great engineers where replaced by digital dummkopfs that don't listen. Lacking the precision methods. handicapping the world with oneness.
