I would not be surprised if those 7 wires are 3 power (blk gry wht) and 4 USB. Maybe it’s actually 2 serial data lines, control and text? Maybe try to trace out the PCB and get any identifying marks from the ICs? If one is a microcontroller or ram or rom or a USB controller that would go a long way in getting it reverse engineered. For real though, they probably are using standards like i2c or USB or rs232, no sense reinventing what works
In a transformer, why are both coils apart from each other? Wouldn’t make more sense to have the ferrite core (tube shape), wind the primary coil around that and then wind the secondary coil on top of the primary? So that the magnetic fields are as close to each other as possible?
I purchased an e-bike which was advertised as just needing the batteries replaced. The li-ion batteries had been sitting dead for months. Once I got the battery removed it was clear that was not the case. You can see the hole where the plastic melted from this component overheating on the board. The burnt one is the same as...
You can replace it with any resistor with the same resistance and power rating. It may be easier to solder a larger through hole resistor onto the pads. I think other posters have figured it out, but you can search for resistor code information to decode it yourself. You can buy resistors lots of places, RadioShack was the go to place but I think hardware stores sometimes have them. If you’re not in a rush I recommend ordering a kit with a few different kinds.
At least in the United States, smoking is something fewer and fewer people take up these days. This obviously wasn’t the case back in the 50’s through the 80’s, where cigarettes were commonly smoked out in public....
I can imagine people having fun getting lost in the flow of playing a competitive sport. I’ve also heard some people experience a post-workout high. But does anyone actually feel pleasure in the moment while lifting weights, jogging, cycling, etc?...
Peertube for sure. Seems to work great whenever I try it, but I’m not a political extremist or European so most of the instances I’ve come across aren’t interesting to me. I would recommend starting your own instance, but also YouTube is YouTube because they actually pay creators if that’s something you’re looking for.

Transformer question
