Diy hot air station
August 11, 2020 - 6:31am

Greetings to you all, I wantvto make a minimalist hot air station from scratch, i have a toroidal transformer with 33V av with a center tap which can supply a max of 5A. I want to make an element with nichrome wire with 500 to 800W output power. Should i convert the 33V ac to DC or just use AC if yes what types of diodes should i use that can handle a constant flow of 5A. Thank u in advance

You need to first calculate the resistance of the nichrome wire that is required for the heater. However, It does not matter if you use AC or DC. I will suggest you to go with AC. The heating will be fixed. 

Make sure about the current consumption of the heater and the transformer could provide that.

DIY Hot Air Station using Arduino (ON/OFF Based Heat Controller). Arduino Pro Mini for all the magic. TM1637 4-Digit Display Module for display purposes. LM358 based amplifier to read thermocouple voltages for measuring current temperature. 4 buttons to set the desired temperature required. BTA16 with MOC3041 and other suitable passives as the heater controller. Manual temperature calibration is needed.
