Adjustable voltage regulator jobs
-500 W maximum generator power. designed for 50-80 rpm . outer diameter about 10-15 cm(designed for mid drive. voltage should be minimum 36 v- and more. 3 gear speed - Familiarization with motor simulation software - Requirements analysis (generator parameters, designs) - Design of stator rotor and housing in solidwork or autocad or other cad program - Modeling of the designed motor with MATLAB Simulink - Simulation of suitable application scenarios
Linear power supply design for up to 24 volts(depending on input voltage and linear regulator selected) and up to 6 amps or output current(series pass transistor(s)?) with as little heat dissipation as possible. The biggest factor for success will be low heat(low enough that a hobbyist can build it) and low noise. A detailed conversation should be the first step.
Hello every one We are looking for a ready and tested open source WMS web based that can be loaded on our own server also that it is adjustable Please contact me for more details Thank you
...interpolated, the interpolation can be linear. There should also be a table editing option for manual entry of points. The table should reflect the curve, and vice versa depending on the last edited point. Curves must be monotonic (only 1 output for the same input), auto correction should stop this from happening. The high and low of the input values, should be adjustable to exclude extremes of the input. The high output value, should be adjustable to limit the output to not the full amount. The curves need to be able to work in either unsigned 16bit mode or a percentage mode to 2 decimal places. (Internal working should be unsigned 16 bit) Examples of curve editors: Although it should be simpler with not exhaustive I/O (input/output) table

( Or maybe we do : A) short press = 2.5mL B) Long button continues until the end or another button. ) 4- Checking the batteries and if we need more power. 5- Adding adjustable knob at the side for controlling the speed. We will need you to ship back the product or price will increase by 500 USD. If any changes we will need to change the quote. Best reg...
Hi Md Masud R., I noticed your profile and would like to offer you my project. The following is to program as required below: Create a function that takes the output of each smoother in and calculates its press statistic. Apply each to the data using the parameters given Now create a function that uses a greedy random search to find better values of the adjustable parameters, based on minimizing PRESS
... Reading of three sensors: -MPU6050 (DMP) -DS18B20 -Analogue Input Calibrating MPU. The two libraries can also be merged, the only important thing is that I also get the offset back from the lib (so that this can be stored persistently). I then need a main that checks the sensors. The program should calibrate the MPU once and then read the DS18B20, the MPU6050 and the voltage cleanly. It is important that the call parameters remain the same and that the offset is also transferred. With the MPU6050 it is important that you use the board's own DMP to read out the position sensor absolutely. #include <Arduino.h> #include <DS18B20.h> #include "OneWire.h" // MPU6050 #include <Wire.h> #include <math.h> #include "ES...

...children's literature, and sometimes even the authors who wrote them. I love the feel of the old cover and would love something with a similar feel, however, I don't have the rights to reprint with this cover, so please don't just copy it exactly. Inspired by is what I'm after. I've included the original cover here as well as a template to use for the SC edition. Please ensure that the spine is adjustable as I have a couple of printers and may need to make tweaks to the spine width. The cover will be used for the HC, SC and ebook. Only a SC is needed for this competition but the winner will also tweak it slightly to work on the HC. This is usually just moving a few elements to allow for the thicker spine and gutter where the HC opens. Files to be s...

We have a board (24vin) tha...modules that are not entirely suitable. Note we are not looking to use ebay modules for these functions. Ideally we are looking for an engineer who will use components for the buck / boost functions. Current draw is very low. The boost is only on for a very short time and needs a current limiting mosfet circuit. The 12v and 5v lines are 0.5A max. The 5v line is usually off also, so a linear regulator would work here. Keen to find an engineer who can provide schematics, BOM, layout. Also looking for someone who will care about our project and offer some ideas rather than just doing what I ask. Very keen to have an ongoing relationship with future work. Prefer to work fixed price, so if there is more info you need to provide a fixed quote, pl...
I have DC/DC step-up TPS5450 to have two selectable outputs with two 10K multiturn potentiometers. When I switch from the first potentiometr to second there is a time where the DC has open feedback and it tries to correct output voltage by going to maximum value of 20Vpp for few milliseconds. (there is a TVS D2 that has a 20V clamp voltage). The normal range of output is 3 - 18VDC and load is inductive. I need to avoid this adding some simple components (resistor, capacitor, mosfet) I can't change 10K potentiometrs and I need to have same range of output voltage. I attached schematic.

...arduino is still being connected (the load). Secondary goal is to read the battery voltage level. Challenge: From reading several blogs I've understood that the Arduino (the load) may not be connected during charging. A solution suggested could be to disconnect the battery when charging and use the power of the charger directly and still be able to use the Arduino. Tasks: - Check electrical diagram for correctness. -- Is this the right solution? Are there any diodes or resistors missing? (Check P Channel mosfet but also the voltage level divider) -- Are the drawn connections all correct? - Check the diagram for safety. Is there any risk when charging or using the arduino like this? - What values for the voltage divider should be used? - Regarding the MOSFET...
I have a done up web caluclator. The calculations are working well. Currently there is a field where the number is static and fixed in the calculations. I want to make that adjustable and dynamic. Example field = A A = 23 Currently the field calcualtion is fixed in the calculation, even when i change A=99 the calculations because its hard coded still take A=23. I just want that field A to take the value i input instead of being hard coded and fixed. Thats the only change i require. Something quick, cheap for an excellent feedback

Project Requirement is to take input from 3 current sensors and 3 voltage lines to measure 3 phase current and voltage. Need to develop ADC reading code with DMA (6 channels) and to convert the values to RMS values of 3 phase current and voltage. Can discuss more once resource is finalized.
I need someone to write a code that records: - voltage from the voltage sensor - current from the current sensor - load on the load cell The load cell will be used to test torque of the burshed DC motor at a given voltage and current. Basically I am trying to figure out the relationship between the voltage, current and torque. As I slowly raise the voltage on the bench power supply, Arduino needs to record load and current. Recording needs to be made on the range from 0 to 3 volts for every 0.1V increment. The output needs to be an excel spreadsheet that looks like a given example. Pictures of the modules are in the attachment.
