Marauder-2. Delta Pulse. Troubleshooting.

[Asanka Sanjeewa]

sorry, are these jumpers

[kt315]

these pads are for tantalums on back side. they setted for general stability and the suppression of a noise on power lines, like always you see
in electronics they used.
that is sweety raisin of the board

do not solder C30 now. i will tell you later why.

tantalums are soldered at LAST STAGE, after the board will be working good and fully tested.

Argh, these traces make my eyes bleed These images and PCBs are a health hazard for an OCD person, viewers beware

Carl, what this guy wants? i sure do not understand his comment.

Carl, what this guy wants? i sure do not understand his comment.

I think he's complaining about the non-orthogonal tracking. People with OCD like things to be nicely lined up.

It was just a joke kt315, I hope you were not offended!

Thank you Mr. KT 315, only i saw your pcb, i did not study your schematic, sorry, some poeple said 25 25 swg coil,16 turns for 1 meter square coil. Is it correct ?

in reality i do not know a difference between 16 turns vs 12 turns. that has to be studied.
try to wind two small coils, 380 and 550 uH, and learn the difference on the depth.
it will give you sure answer.
some people may say what they want to say. its their holy right.

i do not repeat but you have to solder just sound part at first and test sound mentioned in post #53.
look youtube link.
you have to get a sound BEFORE to solder left part. big trouble is the deltapulsers are not able to get sound in simplest circuit
based on NE555. it is shocked me every time.

Dear Mr. KT315
can i use HER207G or BYV29-400 for STTH1210D Diode because here it is no this diode.

[kt315]

yes, Asanka. you can use all you can seek. take the HV diode from 'fat' CRT TV set or better from CRT SVGA monitor.
they are always on radiators there, you will find them up easely near FBT. TO-220 case.

yes, i always offer STTH for 2 euro if sell here, not at ebay. be cause some people are not able buy it from chinese.




Lithuania is degragated state but some things getting from Sweden worldwide warehouse directly.

what is TRASH TECHNOLOGY? why american made electronics industry garbage is better?
why you have to buy nothing for my projects?

Hi KT315. Greetings !!!
Just want your little advice. My Delta Pulse is not behaving normal after my coil wires accidently touch each other while it was powered on.
What may be damaged ? Please guide.

Regards,

new trouble because no basics electronics. absent. ATTENTION GUYS!
you must have THE FUSE. a fuse is setted IN POSITIVE POWER LINE/WIRE
from battery. BETWEEN THE BATT AND YOUR BOARD -!
value of a fuse is 4....5A.
when you test a board from laboratory power source it HAS ITSELF
A PROTECTION. also any impulse power suply has the protection on closes.
then you may not set a fuse IN TESTING PROCESS IN THE ROOM.
but your housing MUST have the fuse, Panel Mount Fuse Housing, usually at backside.
