|  Re: Use of Homebrew wifi modems with the plus/4 safe?
I've tried a WiModem (this one: https://www.cbmstuff.com/proddetail.php?prod=WiModemOLED) but it was not a good experience. I think it's safe but it drags power in great pulses on the 5VDC line and that causes screen flickering and audio noise.
Also all the software I tried out was awfully slow.
About the C64 Reloaded Mk2 Jens Schönfeld wrote this:
The WiModem from CBMStuff has no proper filtering in its VCC connection and draws excessive power in short pulses, which causes visible artefacts in the video output and noise in the audio. This is not a Bug! of the C64RMK2 - but a problem of the device, the vendor of the device must use proper filtering in such cases. (This might be true for other devices based on the ESP32 wifi modules)
Perhaps I just need to find a new power supply for my plus/4 instead of the ageing original one.
