content: This is a threat were you can put all stuff you dont like or hate about you can buy it in a store engeneering.What i dont like in engenneering is why why WHY! have a double sided board and onley solder the bottom but not the top!or put 0.75mm2 cable on a 200 watt rms output or worse 1.5mm2 on a 2kw output etc etc.why do you want to save a few frikking cents on that?Do they really care about if i whont buy it when instead of 500 bucks it's 501 or 2 or 3 bucks!Jeez it is what it is and it cost what it cost.Dont make great design but save on the electronics part!and yes i know 1 cent on a million devices is big but that 1 cent ppl will pay for it!be smart make it good!greets Davyohhhhhh and i hate components thate are not placed correctly on all boards i solder you will find all is perfect and straight!

content: Lol the first time i got a real job in electronics i was a noob, Could onley build kits when work great when not working i had no clue.And in to the trash, Could no do trouble schooting, I had to build a prototype board and few hours later i saw the board and it was raped! ic pins out of feet cables dodged on it etc. I was like WTF!but i did get a comment they loved it to have a board were everything was nice and straight it helps to get a good view on it.Greets DavyPS. We build gas flow meters calorie meter foam meters etc mostly used in chemical plants and university'scan still remember 1 meter from hell when ppl used it they got a static schock! they tried rubber mats erth and so and so one it was one huge mystery why that happend as no other device had that problem.i never want to make custom ovens again used kevlar tube with thick walls and in there you had to put heater in those kevlar things were 2K a piece and count windings every 13 and put it thru the kevlar then start all over, one slip in consentration or crack the kevlar and bye bye 2K oven! ARRRRG!!!!! :--not nice when it's a company with 10 ppl working and you have to tell boss hey i just broke 2 or 3 some there even broke more lolit was a dutch company called annatec and i just said as it was that i had no education but just hobby he hired me and there is were i learned a lot!
