Hi All,

I'm going to move forward and order some parts, will be a while before i can get stuff to work. i might ask a question about a SSR for a heating element.

I really appreciate the help and the suggestions. This really is a great forum and great support!! Amazing!

Cheers,
ruben

Hi Danjperron, rurwin, It's for a drying oven. the temp needs to be between 20 and 45 degrees C. I need to keep it there, with a slight breeze (fans..) for a long period of time. I want to be able to experiment with this a bit, higher temp (45) vs lower airflow and high airflow vs low temp (20). Bec...

Thanks rurwin, I'll have a look at the computer fan and read the wiki article a bit better. The reason i don't want to use the lightbulb anymore is threefold. It's inefficient, the lights are difficult to get nowadays and it produces light, which i don't want. As a heat source it does work, but sinc...

Thanks for all the responses - to take this further, i need to select the devices, it seems. For the Fan, a normal 5V computer case fan works. I'd like to be able to control 3 of those. The input is 5v and MAX of 800mA. The heating element is a bit more difficult. I can't really decide because i've ...

Thanks Sprinkmeier, The PWM would work for the heat element, but (and i'm assuming here) would not work for the ventilator. The reason is that i need a constant stream of air, but want to be able to increase or decrease it based on some variables (temperature, moisture). As i understand it, if i use...

Hi, I've been searching quite a bit for this, but haven't found a solution yet. I want to control a device based on voltage that i put into it. I know the GPIO's will only do 0v, 3.3v and 5v and that they are low power (amps), so those are not usable for me. I want to control a fan's RPM, but also h...
