Hi Guys, (it’s my first post so please tell me if I did something wrong)
so I started building my own Kosmo with some of Sams modules. First, off I ordered a Microbus from Frequency Central. I soldered everything down and connected it to an old Halogen Lamp AC/AC converter that I had laying around (SET150-2 12V 12,5AMax 50-150W) All LED’s turn on and I can correctly measure -12V on the corresponding pins and also the 5V.
Now comes the weird part:
When I watch the +12V LED for a while I can notice, that the LED goes slightly dimmer over time until it Pulsates back to full brightness. And it keeps cycling like that. (the +12V LED is the only led showing this behavior). When I measure the Voltage on the +12V Pin I also get the Pulsating Mesures cycling between 8V up to 11.8V.
I’m a little bit confused about whether my AC/AC Power supply is broken or not suitable? (It should have enough juice since it says 12.5A max) Or is my Microbus broken and I did something wrong soldering it? (I’ve checked every component 3 times now)…
I’d highly appreciate it if someone has an idea what might be the problem here…
il you’re interested, I can also upload a video of the behaviour.
Cheers guys and have a great day!
Love from Hamburg Germany <3
