Hello! How’s it going? Long time no see. I used to log in here literally every day, but our paths diverged and… anyway, I hope you don’t mind me popping back to gather the community’s thoughts on something.
Does anyone still use the Tenori-on? Or am I the only one? Sure, it’s hella limited, but I enjoy messing around with this weirdo of a sample player.
I have the later, cheaper TNR-O, the plastic white one with orange led, as opposed to the metal one. I’ve never really wanted a metal one over the plastic one, apart from one thing - the battery power.
I’ve considered buying a 12v battery pack and velcro-ing it to the back but that isn’t an elegant solution, so today I thought to myself - I wonder how much of the original Tenori-on guts were left in the plastic revision and it turns out, A LOT.
Here are some photos of the inside of the original: Tenori-On Teardown « bunnie's blog
And here is a photo of the inside of my TNR-O:
The eagle-eyed amongst you will see that they’ve used exactly the same circuit board, but haven’t populated the back LED display (look at all those blank solder pads), or the battery connector to the left of the power switch.
I’d like to add a USB charging board, and a rechargable battery, and solder it to these connections, and from the photo on the site I shared I think I can work out what goes where. I just have a few questions:
-Does anyone else own a TNR-O and want to join me in this quest?
-Would anyone be willing to offer advice and support on batteries and charging boards? I know a little, but only from doing mods to other devices that others have already documented.
-The only issue I can see is if there is more to the TNR-O switching between battery and mains power than just adding a battery. Does anyone know if there any way to check this before I start on this mission?
