The Google translate have a error.That post mean "(I)was in the front row,who need the peanuts/pop corn/rice pudding?I can sell to you"It means "bump",and play a joke to the the later posts.It's a funny reply in some China's Forum. Fang Date: Wed, 14 Oct 2015 05:39:15 -0700 From:

[neonixie-l] Re: Super easy wall adapter mod: 9V plus 170V at 80mA

Just modified a second unit... so easy. By adjusting the output winding turns I should be able to get just about any voltage I want, i.e. 300V for a dekatron project etc. I replaced the 2 conductor cable with a 3 conductor cable that can handle the high voltage. Anybody want this unit? On

Re: [neonixie-l] Super easy wall adapter mod: 9V plus 170V at 80mA

No sawing. You shove a flat blade screwdriver between the output cable strain relief and the cover and pry it up. This breaks the weld which you then work around until the lid pops off. Very little plastic deformation which then glues back together in a snap after the mod. Once thing... you

Hi Ron, most interesting is the clock can chime with Chinese, English, Japanese and German, and use 2 18650 Li-battery can works for 10 hours.

I'm curious about adding windings to the transformer. Is this particular transformer constructed so you can pop-out the bobbin, or does it have those obnoxious interleaved E-cores that require you to split them all apart, recoat, etc ? Or worse yet, thread each turn thru the core ? -- You

Re: [neonixie-l] Super easy wall adapter mod: 9V plus 170V at 80mA

John, That's a clever hack! Once thing... you had to saw apart the ultrasonic weld to get it apart, right? Any good ideas on gluing it back together? Also, this is not strictly still UL recognized since you modified it, but it's close enough. Do you consider it to be as safe as the original

Thanks John, I researched the scale size of the original Divergence Meter in Steins;Gate, make sure appearance same. Then I design the 3D model the check it, lots of fun.

My "Thin" wire is #43 or #50. This stuff feels like wire brush bristles when I use it. Running a long time test: 185V at 75mA plus 9V at 100mA. Diode temperature rise is 8C and ripple on HV is 78mV RMS. Going to let it run til Saturday morning (When I need my bench back). -- You

High frequency switchers use ferrite EE cores. You cant really see it from the picture but the center posts are slightly shorter than the legs (About 0.015" total) and they are glued together with a drop of epoxy on the legs to hold them together. The reason that they gap core is to lower the

Re: [neonixie-l] Super easy wall adapter mod: 9V plus 170V at 80mA

All high frequency switching transformer cores are cast ferrite. No laminations to deal with. They are called E cores because they look like the letter E. John said that after he removed the transformer from the board, he separated the ferrite core halves by heating the glued joints with a

Here's a closeup of the re-sealed housing with the re-fitted strain relief. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group. To unsubscribe from this group and stop receiving emails from it, send an email to

A more elegant method for adding the 3 conductor cable (Than that showed in my photo) is to take the original strain relief and pull out the wire and then drill it out. The new wire is then slipped into the strain relief. -- You received this message because you are subscribed to the Google

Re: [neonixie-l] Super easy wall adapter mod: 9V plus 170V at 80mA

I did the same process on an HDP24-1AWA01FZ (12V @ 2A) of which I have a couple hundred scrap units and am getting a clean 170V at 140mA. These units are welded better so I should find an easier way to open them. This is so much easier than the way I tried to do it years ago by trying to

Looks lovely. Google Translate loses the plot slightly on your page - one of the comments gets translated as: "Front peanut seeds sold rice pudding" Maybe that's correct who knows ? Nick -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
