Shorting 4.1 in midi interface

[Remi_Music]

Hey, I've got a breadboard going for the 4.1 midi interface example, (just RX1/ pin 0 for now)
when I attach the 5vin-->1uF capacitor-->ground, it winds up shutting down. (and doesn't seem to transmit messages without it)
Advice?
Thanks!

I hope you do have a multimeter. If so, what does it read at the orange line when the error ocuurs?
Is your 0.1uF capacitor indeed a capacitor?
What does "it winds up shutting down" exactly mean? Teensy runs fine but when you connect the capacitor it stops functioning?
About "and doesn't seem to transmit messages without it": I'm not sure what you mean here. Transmitting MIDI is on pin1.
How do you power the Teensy 4.1? By USB?
A photo will definitely help!

sorry, Rx1 for receiving messages, (and it doesn't receive any yet, but the midi setup does see it before attaching the capacitor between ground and 5VIN)

The teensy is powered by usb,

When I attach the ground to the capacitor, my macbook shows this message, and the multi meter shows no power on any pins.
(and the capacitor is showing .1056uF)


here's a photo of the wiring,

Woah! Woah! Slow down there. You're shorting Ground to 5v!!! Remember that the numbered rows on a breadboard are electrically connected. No wonder your Mac ain't liking it. Remove that ground wire next to the cap, and just put the capacitor across pin 5 and pin 8 of the 6N138. But I'd double check ALL your wiring before powering it up again.

There's a good example here of this circuit in breadboard.....

MIDI in schamatics

Hello guys, I’m a software guy, not an hardware guy. I would like to connect to add Midi In to my Daisy Seed. I have found this schematics. The difference is that I use 1N914TR diode instead of 1N418. Here is my bread board Do you see any issue. Is it safe to plug with Seed ? Thanks...

WOOPS.
Sorry guys, I thought I was rested enough not to have the saturday stupids yesterday, but apparently it was an uphill battle.
Thanks for the replies, got it fixed up!
