Hello Swagatam, thanks for all the information you give us. I want to build a speed controller for a 90 V dc motor, variable speed, 11 amp. I think is possible to use a controller for an Ac motor made with triac and diac and then to use a rectifier bridge to feed the motor. About H BRIDGE I don’t want ready made IC to drive the N-MOS.i want to experiment by myself like you did :).I want to drive bipolar stepper motor with all possible options like chopper and microstep but without ready made IC.and with variable powerfull power supply till 50v to test various stepper motors, I want use only P&N MOS as driver. Just install the 2 jumpers labelled D12 and D13 above the Motor power connector. That will connect the Digital pin 12 and Digital pin 13 (normally used for the spindle) to the Step/Dir pins of the A driver. Driving the A motor is then just like the other motors. And now, on to the software … 😎 The motor rotation can be flipped or reversed within a fraction of second. The speed is variable in both the directions of the motor rotation. The two 555 ICs are assigned with two separate functions. One sections is configures as an astable multivibrator generating 100 Hz square wave clocks which is fed to the preceding 555 section inside the ... Hai. I would like to have a variable power supply. This supply has to be varied based on an voltage input in the range 0-10V or 0-5V. This external voltage input comes from a PLC analog output. So for example the Variable power supply is in range of 0 -30. If plc sends 1V then the supply should give out 3V and so on. Thanks in advance I can always use a DC/DC convertor to convert the 12V to 5V DC. Original: PDF How to make a 0 to 12v Variable Transformerless Electronic Power Supply or LED Driver or Electronic Dimmer at home. I would opt for a +/-12V dual supply for cases when you also need a 12V battery voltage. Figure 1 The basic circuit of DC to DC boost converter. While the switch opened the collapse of the electric field. Makes voltage of the inductance L to the left of a positive return is negative.so result is that the voltage between the input and the coil’s voltage has the same phase as the battery series (In-phase) the end result is Makes voltage of output increases. Diy treadmill motor speed controller Power protection and control ICs are used to monitor the input voltage to a load to ensure it is within specified bounds. If an out-of-bounds level is detected, a protection and control IC can either regulate the voltage or current, or switch off the power source to protect the load from damage.

2021.11.27 17:45 Technical_Yard_7196 Is it possible to amplify 5V from an Arduino to 50V on a variable motor?
I'm currently trying to create some sort of variable motor requiring much more voltage than the Arduino can output. Lets say if this motor required somewhere > 50V to operate, would it be possible to scale the 5V output from the Arduino using a NPN transistor? So I would connect a 50V battery to the collector, the PWM from the Arduino to the base, and the motor to the emitter. Would this even be possible? If not, what are some other options I could do to make this work?

2021.11.27 17:45 postmastern Зонд «Паркер» завершил десятое рекордное сближение с Солнцем
| Солнечный зонд «Паркер» завершил десятое тесное сближение с Солнцем, установив новые рекорды по скорости движения и близости к звезде. Он оказался всего в 8,5 миллионах километров от фотосферы, двигаясь при этом с максимальной скоростью 163 километра в секунду, сообщается на сайте миссии.|
NASA / Johns Hopkins APL
«Паркер» был запущен в космос в 2018 году и на данный момент совершил десять сближений с Солнцем из запланированных 24. Он ведет исследования солнечного ветра и внешних слоев Солнца, причем каждый следующий перигелий оказывается все ближе к звезде. В конце 2024 года зонд практически войдет в атмосферу Солнца, оказавшись вблизи точки Альвена, где солнечный ветер ускоряется настолько, что покидает звезду.
16 ноября 2021 года зонд начал десятое тесное сближение с Солнцем, а 22 ноября пролетел на минимальном расстоянии 8,5 миллиона километров от фотосферы звезды. Это рекордное значение, эквивалентное 22 расстояниям от Земли до Луны. При этом аппарат двигался со скоростью 163 километра в секунду относительно Солнца. Десятая по счету фаза сближения завершилась 26 ноября, ожидается, что в период с 23 декабря по 9 января зонд передаст все собранные научные данные на Землю.
«Паркер» сделал уже немало уникальных открытий — показал структуру солнечного ветра, определил механизмы ускорения частиц около Солнца, а также увидел след астероида Фаэтон и околосолнечное пылевое кольцо вблизи Венеры.

2021.11.27 17:45 norgrenator Ditra heat underlayment question
I just finished laying down my ditra heat mat on the basement concrete floor and everything bonded really well I did the peel check as I was laying and and had full coverage however now that it’s dry I noticed a small 8”x8” section didn’t bond and I can feel it’s not bonded if I step on that spot. The tiles for floor are 12x24 large tiles is this going to be a big issue if it’s only one small spot and if so how do you fix that?

hey everyone i just got accepted into tuj and had a couple questions :) first off is it worth it, or should i just do 1 year study abroad at a different school? i have only the basics down for the language, but plan on taking japanese throughout all 4 years (i think it’s required). since it’s in the center of tokyo will i need to have japanese proficiency to find a job, or are there jobs available for english speakers? if you guys have any other advice or anything please just let me know:)

2021.11.27 17:45 DestinedEinherjar So I was messing around with the Shaymin glitch and I was able to reach the locations for full moon island and newmoon island.
So I was able to reach their locations but unlike Shaymins island, I couldn't seem to find the actual islands. They're on my map now but I just could not get them to spawn. It's definitely like the old glitch where you have to run across the map, but after getting to the route where all the snow is the game glitches out and your sprite goes into a t pose. I somehow ended up finding both those islands but my screen was completely black and I couldn't pull anything up or interact and so I started roaming and I realized the map circled back to Flower Paradise but again everything was completely black. So I decided to start over and head straight east instead of going across the entire map.
So I forgot to record how to get to where the video starts so I'll try to explain as best as possible, so where in the original glitch you get to the path that you take straight up to Flower Paradise instead head to the right and you'll be able to surf again go towards the right while surfing and you'll hit a spot where you'll get off Bibarel and you'll be able to go straight up, so keep going but hug the left invisible wall until you reach Flower Paradise again but this time you can go around the island and that's where you can head whatever direction you want. But for what I recorded I went straight east and that's how I got both the islands to register on my map. I'm hoping this will help someone else figure out a way to actually get on Newmoon.
Apologies if the link is weird, I've had a hell of a time trying to download, splice and upload this damn thing;

2021.11.27 17:45 BluSmaug Sony 70-350 for APS-C or full frame ?
I have a Sony a6400, currently with a sigma 30mm 1.4, which is obviously limiting in focal length. I started photography a few months ago, my interests are landscape and wildlife (family travel pictures as well).
As expected, I am a little frustrated with the focal lenght of the prime.
I can get a good deal for the Sony 70-350, which seems like a great lens for aps c, for 580€. As with all my purchases... I have difficulty deciding on buying it or not.
My main concern is that when deciding between fuji and Sony, I chose the Sony ecosystem telling myself I would buy FE lenses for the upgrade path to full frame one dayb without having to sell and rebuy.
Do you think the 70 35 is a good deal or would you wait to buy a full frame lense like a sigma 100-400 or sony 70 200 f4 ?
Thank you for your advice !

2021.11.27 17:45 ChicanoProphet Anyone else find this deep fake documentary to be bogus?
The more I watch the series the more I think Peter Jackson and his CGI team took WAY too many liberties. Compared to actual Let It Be film sessions and conversations that I’ve seen before this release, I have trouble believing the authenticity of this release.
It would explain why it took practically two decades to produce something with the footage, a lot of which was reported to be damaged.
They made John a little too silly. The John I know is cooler than this by a mile. And I doubt they had audio of this supposed private meeting between just Paul and John.
And Paul’s “and then there were two” line seems a little contrived. A whole group of people just there letting Paul reflect on this and staying quiet is bizarre to me.
Plus the scene where John and George pretend to get into fisticuffs just looks off to me.
There are more things that I think are off but I wanted to suggest this to some real fans to see what you all think.
