3D printable IR-UART TTL-Adapter to connect DER EE DE-5000 LCR Meter to PC. Created with Rhino 8.
I stumbled across a thread on eevblog-forum about a Software to connect DER EE DE-5000 using a selfmade Infrared-UART TTL bridge. There was a 3D printable enclosre. Since i own a DER EE DE-5000 LCR Meter, i redesigned the enclosure a bit to fit the conture of the device.
The enclose consists of two parts that clamp together. When inserting the adapter, press a bit harder until it snaps. Inside is a CP2102 UART adapter, a L-53P3C IR phototransistor (long leg connected to GND, short leg connected to RX) and a 4,7k Ohm resistor. The resistor can have any value between 1k and 10k. I choose the 4,7k one because i have plenty of them. I used some Kapton tape under the resistor.
The software can be found on the internet. Should also work with TestController (well known java app). I use 19200 baud 8N1, and on Windows, i disabled power saving in device manager for this device.
For printing the enclosure, i used PETG and a 0,25 mm nozzle on my Prusa MK4S at 0,12 mm layer height.
