    Need Help With Ozone Generator Rheostat Please.

    The fan speed can be controlled via a regular speed controller, close to a light bulb dimmer. The high voltage supply can't be adjusted afterwhile, the manufacturer as to provide the option (who technically is implemented before the voltage multiplication).

    Ultrasonic cleaner circuitry repair

    That's cool! You can finish to refurbish your GL1000 now ! :)

    ATX power supply - multiple outputs

    You have a maximum current by output. For the 5V it's 30A = 150W. For the regulation it's also better to star connect the outputs from the supply PCB (as done for the existing wiring)

    Getting into the smartphone/tablet repair business?

    Those guys are awesome: https://www.ifixit.com/ and thank you because repairing stuff is a good idea !

    About cheap projector

    Please don't buy designed to trash products , the environment is suffering.

    Is there a chance to get blind or serious physical damage while prototyping ?

    Already being face hit by a small piece of an exploded SMD ceramic cap, supply was far bellow 40V! So I recommend safety goggles too.

    Looking for a component marked "made in Austria"

    Dear Steve, I have a 0603 10K resistor stamped "Made in Austria" its' written between the date code and the serial number :cool: Olivier

    PCB track width and high current with Mosfets

    That's look OK, the soldering is a bit generous however you can probably go for a maiden test. To improve the layout a bit more room around the FET should allow you a cleaner wiring. Maybe the XT60 connectors can be soldered directly on the PCB, no more wires so. Olivier

    PCB track width and high current with Mosfets

    Assuming a D2PAK the leg cross section is around 0.5x1.2mm not that bad knowing the very short length and compared to a few mm wide PCB track who is very thick. Can you post a snapshot of your PCB layout?

    Finding the beep!

    You welcome, but being thanked to make something fail, what a shame ! :D

    Finding the beep!

    J1 looks to be the beeper. He is probably driven by the NE555 pin 3, to be checked.

    PCB track width and high current with Mosfets

    If the boards are assembled professionally you can remove the solder mask and add solder paste on the track. This is the industrialized equivalent of the over tinning method suggested by chopnhack.

    Why put MOSFET's on negative side vs positive of motor

    Also to be noted that the left circuit is sometime preferred because he is more fail save. If a short to the GND happen the load is not supplied unlike with the right one.

    uses of wavelength

    The relation between color and wavelength is available here: http://science-edu.larc.nasa.gov/EDDOCS/Wavelengths_for_Colors.html The light become less visible because she is not focused and so spread rapidly. On the other hand a laser is a highly focused light who can hit with the "same"...

    Converting a business to LED lighting

    T8 and T12 led replacement already exist, see: http://earthled.com/collections/philips-enduraled-t8-led-t8-t12-replacement-tubes Don't know if you have specific needs, but the development and the certification will be expensive.

    Connecting Circuit to 12V Power Supply

    If you are in UK the 315MHz is not allowed. 312-315 MHz band is reserved for Earth-to-space, see: http://www.ofcom.org.uk/static/spectrum/fat.html

    preperation for developmemt

    They are TOONS of work between an almost working prototype and a marketed product. Industrialization is a huge job! You must think about reproductibility, testability, reliability, maintenability,mechanical integration, certification,parts sourcing...

    How to identify capactiors

    Looks OK, you can maybe buy few caps as spares..

    How to identify capactiors

    You can mix and match them, it doesn't hurt at all.

    How to identify capactiors

    No you don't need to use the same serie , it's just a manufacturer "classification", if you want to ease the finding select only one manufacturer, I use Panasonic very often.
