but did you finish the story?

I hope you put up DT signs

thats fair. i stopped for a while after getting bored initially too, so i get it lol. the game is kind of a slow burn at first but around chapter 5 is when it starts to get really good
I committed the cardinal sin though.. I watched playthrough and game breakdown videos afterward. I know what happens, but my impatience got the better of me, so now its ruined and Iāll never return. Lesson learned? Naa.. Iād do it again

TIL that Pilgrim was on the design team of the Razer keyboard that I criticized not that long ago for being buggy:
Joking aside, some comments about the keyboard
As far as the hardware goes, the two guys who actually designed it did a very good job. Although the bottom MCU PCB couldāve probably been a single sided load design instead.
On a side note, why is the project manager going by the name of āMasterChiefā? Very PM of them. 
On the firmware and software side of things, well, this thing is messy. The wireless and RGB are unreliable, on a wireless keyboard that includes keycaps that require backlighting for the characters to be visible. And donāt get me started on Synapse, Windows Dynamic Lighting support, and how the pairing two devices to one dongle breaks things.
āNobody Knowsā did the SWQAā¦
But at least is has nice foam and the typing experience feels great when it works:
I think that Iāll ultimately settle back on my old 65% Asus keyboard that I have and buy a lightweight non Razer mouse. Somehow these guys managed to create a product thatās good enough to get past the return period but might drive you up the walls with a future software update.
In the grand scheme of things, I canāt complain. I bought a mouse and a keyboard to save a USB port and dodged the bullet of buying one of their laptops.
Edit: Why does Razer add polyfuses to every single USB device? Does a little receiver dongle thatās little more than an MCU and an antenna really need one? Besides, all USB host ports are required to have overcurrent protection. And if thereās a short, itāll probably happen in a cheap chinese cable instead of inside of your product.
@Satur9, what are your thoughts on this? I donāt place fuses un USB powered devices. Chinese designs seem to have them but they donāt use reason or logic when designing things.
But USB aside, china also adds fuses on the output of switching regulators that already have overcurrent protectionā¦ They donāt understand that the fuse goes on the input side of things in case the mosfets fail short in the no-name chips that they use. 
But maybe Iām a stubborn engineer when it comes to certain things.

Ok, Iāll admit that Iām feeling a bit lonely and want to talk about interesting things.
I know that most things arenāt designed to last forever while abused in an industrial environment.
I would add anymore ā¦ i miss my Alcatel one

Is it a wired mouse?
Wireless keyboard and mouse. But they can be used with a USB cable. Thereās a polyfuse in the keyboard itself, and another one in the tiny receiver thing.
I still have to take the mouse apart to check, but I suspect that it has one as well. And I also suspect that most other companies are just relying on the USB overcurrent protection instead. Besides cables are bound to be the problem instead.
Well redundant safety features arenāt a bad idea, especially in mechanical devices where the user could induce a short by using the device incorrectly or dropping it. Polyfuses are also included sometimes for transient voltage suppression when the cord becomes an antenna for external signals

Along with TVS diodes, ferrite beads, etcā¦
Meh, Iām just thinking that itās a weird design choice in this case. Just like having SMD parts on both sides of a big low density board or having a separate antenna when it couldāve been on the MCU/wireless board that sits on the bottom of the keyboard right against the back of the case.
At the end of the day, Itās good hardware and I have nothing to complain about, Iām just lonely and want to talk shop. On the other hand, their firmware and software is junk.
And I might be selling a year old keyboard that was never exposed to food relatively soon. Razer Synapse 4 has absolutely nothing to do with thisā¦
I tend to criticize when they add unnecessary corners that donāt make things better, and I also criticize when they cut corners that should not be cut.
But then again, I often judge my designs harshly to try to make things cheaper and better.
Okay, I could use your advice on something. Iām doing a design for a client which is a portable wireless light. It will be charged via USB-C and will have 4x user-replaceable 18650 batteries in parallel. The problem is that in most products the cells are charged before inserting in the device which pre-balances them so that the voltage difference between the cells is minimized and they can naturally balance safely. In this case though the user could insert one cell at 3V and another at 4.2V and I need to protect against that scenario and have the device manage charging and cell balancing. Unfortunately from my research most of the cell balancing asics used in industry are for balancing series cells. I need a solution that manages charging and isolates the cells from each other during charging, but allows the system load to pull from them all in parallel for higher capacity. I could do it myself with the MCU and mosfets but for safety and simplicity I would rather have an asic dedicated to handle that

Somebody shared this so now Iām looking at the LTC4412
The first thing that comes to mind is using 4 separate chargers. And depending on how much the lights draw, either 4 diodes, or 4 current limited switching regulators or something along those lines.
I need to give that article a read, but the LTC4412 looks really nice and it can give you information on how many batteries are being used at the time if used in the discharging side of things.
Also, are you using protected cells or random cells? I personally dislike unprotected cells but adding a Li-Ion protection circuit might be worth the effort if you donāt know what the end user will employ.
I love this. I was thinking the whole time of getting my scar healed āhmm, I kinda wish I had like 2 or 3 little tiny pouches over 1 medium pouchā

Luckily protected 18650s are a different length than unprotected

I grew up controlling my cursor by taking the ball out and sticking my thumbs inside to manipulate the rollers. They were cheap spares from a relativeās office, and I had no room for a mousepad anyway. I once played Counter Strike using mousekeys, got multiple headshots, and didnāt come in last place. So for me, all mice feel wrong. Only keyboard feels right.
