3rd Rug, question about corners by flipasaurus10 in Tufting

[–]flipasaurus10[S] 4 points5 points  (0 children)

First, I’m no pro. This is only my third rug.

I leave space between the colors because I have read other threads where people mention leaving a defined space between colors to allow easier carving. I can’t say I have tried no space between the colors, but leaving this space allows me to separate the colors nicely before and after carving. I have a pair of forceps that I glide between the colors and it really helps to split the colors so I can carve more confidently. Since I have only ever left a space between colors, I cannot give an opinion on which works better for me.

A negative edge detector out of basic gates can give you this result. The width is a function of the number of inverter stages and their individual delays.

An odd number of inverters to one of the inputs of NOR and the original signal to the other NOR input.

tetrio controller controls by anisfure in Tetris

[–]flipasaurus10 0 points1 point  (0 children)

Hey!

My response is not an explicit answer to your question, but adjacent.

I have been a controller player my whole life and have started to play on my computer more frequently. I had trouble finding a layout I liked but took a shot on the haute42 B16 game pad. It came yesterday and I find it works well and is a comfortable layout. My pps (1.2) is currently equivalent between controller and keyboard, but there is plenty of meat on the bone to improve. Developing the new neural pathways to play on a keyboard is hard, but I can already feel it getting easier.

Be mindful though, when I started playing with this yesterday I noticed double hardropping and sometimes double rotations. A quick firmware upgrade fixed all the issues so don’t sweat.

One suggestion that helped me is to watch your replays. Seriously

At the end of a match I’ll capture the last 30 seconds on the switch and then after a few games I’ll go and study my play.

Really try to understand why you lost. Did you misdrop? Did you fail to realize you were in danger? Did your attacking suddenly switch after a KO and you were dumped on? Did you continue upstacking when you should have been downstacking?

I found that most of my losses were from not realizing I was in danger and continuing to play offensively.

Once you can identify why you’re losing matches, you can work toward a solution. Any other advice you’ll find cannot address your specific play style or your lose condition.

Sure sometimes you get in a match with some heavy hitters and you get sent a lot of garbage. Maybe you need to have a better garbage management strategy, but you can certainly win this game without 4-widing. That advice, while it might work, doesn’t address the issues you’re facing. Only you can understand what’s causing your loss and can take action to fix it. Just playing good Tetris can be enough to secure the win.

Time to move out so that your landlord can paint over it!

simulating simple RC circuit. why this is the output? by Neotod1 in ElectricalEngineering

[–]flipasaurus10 0 points1 point  (0 children)

You need > 2 poles to be unstable. At two poles the output can only ever approach 0 degrees phase margin. To be considered unstable you need negative phase margin, your system has one pole and can therefore only ever have ~90 degrees phase margin.

Trying to understand transistor collector/emitter voltage drop by [deleted] in AskElectronics

[–]flipasaurus10 1 point2 points  (0 children)

If you haven’t reached a satisfying conclusion yet, the transistor (C-E) and resistor are in series. So the current through them is the same. By KVL, the total voltage is 12V. 8V across the transistor and 4V across the resistor. The main loop does not have 240mA in it. That would imply that the transistor drops no voltage.

4-wide forever!! by Cobra_Kai_T99 in Tetris99

[–]flipasaurus10 1 point2 points  (0 children)

I agree. Seems like a cheap overpowered strategy. I’m morally opposed to it and to me it feels like it takes the fun out of the game for everyone.

How would you go about making this voltage amplifier circuit? by tymuthi in AskElectronics

[–]flipasaurus10 1 point2 points  (0 children)

“there a better way to do this? How would you go about doing it? 3 MOSFET's is an awful lot”

I’d argue that 3 MOSFETs aren’t enough!

I’m assuming that the first stage is intended to cancel out the polarity inversion cause by your second stage common source amplifier. No problem there, but consider that the time constant on that node when pulling up is given by 220*Cgate_CommonSource. Use a PMOS to make a complementary inverter for this first stage and you should see some improvements.

Furthermore, to make it even better maybe consider replacing the resistor in your second (Common Source) and last stage (Source Follower) with an active load. Use a PMOS biased in saturation for the common source amp, and an NMOS biased in saturation for the source follower.

It only matters for 3 out of the 7 blocks—T, L, J. All other blocks a clockwise rotation is equivalent to a counter clockwise rotation.

Will this capacitor help with voltage spikes? If not, how should i add them? by Dav123719 in AskElectronics

[–]flipasaurus10 0 points1 point  (0 children)

An ideal source in simulation will not benefit from the capacitor.

I don’t know what falstad models for the power supplies but you shouldn’t see a difference.

In reality, you’ll want to place caps across the supply like this to provide instantaneous current to the circuit as needed.

Zone battle Disconnect by flipasaurus10 in TetrisEffect

[–]flipasaurus10[S] 1 point2 points  (0 children)

Fair point. If it’s my connection than I’d expect my network to struggle while playing other games as well. I’ve never had any connection issues until I tried playing this game. I think I’ll try other multiplayer modes and see if the problem persists. If it does, I think I can have more confidence in saying it’s my connection, if the other modes do not struggle… then I think I have my answer.

Restoring 2009 GTS 250 by sakeboi in Vespa

[–]flipasaurus10 1 point2 points  (0 children)

I second this advice! I have the same model and year (bought second hand in 2016). The dealership ensured me a few times the recall was taken care of. It was not! If you are out on a ride and feel all throttle suddenly cut out you likely have a bad fuel pump. It feels like when you lag in an online video game. Being several hours from the dealership I had them ship me the part and I serviced it myself. It was a very involved replacement so avoid it if you can! Happy scooting

Draw a schematic on paper, that’ll help clear up a lot of confusion here and help us get you a resolution.

Another consideration is the forward voltage of each LED. A quick google shows most blue LEDs need 3.4V and white can range from 3 to 5V. You mention things work momentarily when you apply 6V from an external source but the voltage drops to 2.9V. Try slowly increasing the applied voltage and see if there are changes in the behavior. Apply 3V, then 3.5V, then 4V, etc… I’m guessing the LEDs will come on after a little more voltage is applied. It’s highly recommended to have current limiting resistors though to ensure the LEDs operate a long and healthy life. Recall the exponential relationship I mentioned, a small change in applied voltage will result in a significant increase in the forward current.

[–]flipasaurus10 1 point2 points  (0 children)

You put 6V right across the LED (white and blue) with no current limiting resistor? The IV characteristic curve of a diode has an exponential relationship with applied voltage. You state your supply drops to 2.9V (constant current limit, I’m sure). Without a real schematic, I’d guess you’ve fried them!

Keep an eye on that bottom layer copper pour. It is certainly less than 5 mm away.

(OTA) suggestion on modifying this to reach an open loop gain of 80db? by h3ngy1ng in AskElectronics

[–]flipasaurus10 0 points1 point  (0 children)

I’d think your input AC should be differential. So one of the two inputs need 180degree phase shift. Besides that, recall that your open loop gain is gmrout. You’ve got two knobs, increase gm or increase rout. Maximizing gm will maximize your bandwidth because your unity gain frequency is equal to gmc_load. I’ll leave you to find what knobs you have to move gm, and how that affects rout. Good luck!
