This is not non-fluency, i am not fluent in English, it looks like some kind translate. ---

In general around here, we do not poke fun because of poor translation. Loads of folks come here where English isn’t their first language and I don’t want anyone to feel like they have to have perfect English or be made fun of. If someone is using an online translator, I would rather they feel welcomed. To be clear, I am not talking about finding differences between languages funny as a problem. The problem I think is when there is an air of superiority. The Mr. Shi Eating Lions poem, thats a funny quirk of linguistics. This reads more of a “haha, they dont know better” which is a bit mean spirited. Probably not a huge issue, just my 2¢. ---

On the other hand, this is a commercial product made by a company out to make money, and they could easily have found someone who would have done a better job – it’s not like there’s a shortage of people who knows both Chinese and English well – but they just didn’t care. I don’t see a problem making fun of companies. They don’t care anyway. But on the other other hand, this thread is for people making fun of their own mistakes (especially of the “oops didn’t think of that” variety), so commercial products don’t really belong here, whether you find them funny or not. ---

Sorry if the poetry link came off as trite - I was clumsily trying to imply that Chinese is difficult and we’d probably butcher it just as much, given its tonal character and nuance. ---

Nah, i was already aware of this poem, and its a funny linguistic joke. This specific response was intended just as a stop gap measure. I dont think anyone meant anything nasty. This is one of those instances where I can see complaints either way. Ill just leave things like this to the usual “flag it if you need to”, otherwise ill just assume things are fine and keep out of it 🙂 . ---

> without checking the price… A few dollars. Or you can get a blank microcontroller for around one dollar, and a PIC programmer for $50 (for official ones, clones are $10-20), and roll your own. Might work. ---

A couple things going on here… 1. I placed a 7805 in kiCAD and saw it auto-populated something like TO 3 in the footprints and ASSUMED that was a TO-220 3… it wasn’t. 2. I grabbed a regulator from my 7805 bag and soldered it in, only to realize that was actually a LM1117T -3.3v regulator. ![Untitled](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/2X/6/6f4cb3f8cced595257b9295d3cbb252cd8553a38.png) (sorry for image quality, i have fine motor issues) ---

I feel like such a nitwit. I couldn’t figure out why my new K25 LFO worked perfectly at first, and then I started to have problems in the low range. Today I Learned, tantalum caps are in fact polarized. OOOPS. ---

You can take two polarized caps back-to-back (neg to neg) and you have a bipolar cap. Use the same value. For example 10uF back to back with 10uF gives you a ~~10uF bipolar.~~ 5uF bipolar edit: oops dumbassery ---

Thanks always good to have more workarounds. I read that is basically how they make bi-polar electrolytic caps. I already have a pretty large Mouser order shaping up to get parts for the kosmo braids someone posted on here, so I just put some bi-polar 1uF caps in the order with it. ---
