Breadboard Thermocouple Sensor v1.0

I'm a software engineer. I'm not an expert at soldering. I'm not an expert at etching boards either. But I want to build a thermocouple sensor v1.0 for replacements of my 3D printer. Thus I use breadboard to create one and it works good enough for me.

BOM:
* IC1: AD595AQ or AD595CQ
* C1: capacitor 104 (100nF)
* R1: resistor 330 ohm
* LED1: red LED
* J1: 2P 5.08 mm screw fixed terminal
* J2: 3P 5.08 mm screw fixed terminal
