No schematic? ……..thx
OMG get over the 'alignment'……….who gives a f&ck
IRKS me that the LEDs are not touching…..WHY leave a gap between them?????????????????????????????????
to see parts of a datasheet for your own use is ok + you are promoting their hardware,
you are not a company that makes an electronic component and
copies the original datasheet + then pretend it is home-made.
What is the reason you have the male header on the black PCB facing downward instead of upward which make installing the yellow PCab much easier
This project is the longest running project known to man. Rebuilding the Great Wall of China will take less time than for Julian to finish his Vocoder ๐
ALAN PARSONS PROJECT…a bit of a fav of mine. Ain't got a clue what you're doing but notwithstanding that enjoyed it thoroughly….Cheer J
Hello Julian. I'm quite new to this sort of thing so i have question about capacitors and batteries. Is it possible to charge a capacitor with a lipo battery? If not please explain why not.
Blue for revision four!
These videos are great for helping me get off to sleep, keep up the good work.
nice design thought with the mounting there !
maybe you could use a 1.6mm H-profile to fix the pcb between the others.
I picked up one of those crimping tools that works on those connectors, but most of the time, I simply crimp the one around the insulation first, then put the wire in a hemostat to hold it upright and with a sharp little needle type soldering iron tip that I usually use for SMD connections, I put just a drop of solder on the connection and wire, whilst heating the other side of the connector. I have had great luck with this method both with those little connectors and others such as the dupont type as well. So long as the spring connector is above where you solder gravity seems to protect the connection and the solder flows down
Why are you surprised that the signal didn't peak into the red? The producer's / engineer's job is to make sure that doesn't happen except for very fast transients! Looks to me as if your VU meters are spot on.
Reminds me of a project I did for a TV production truck. Needed additional meters for the audio board. Company wouldn't spend $1,500 for a meter bridge, so I requestioned a bunch of DYI meter kits as "replacement parts" for $250. Installed trim pots on the inputs for calibration.
Yes, you finally labelled your connectors ๐
