      To control the heater element ON/OFF High Current 210A MOSFET Upgrade RAMPS

      I have ordered some of these to try them out has anyone used this module before

      3D Printer Heated Bed Power Module Board High Current 210A MOSFET Upgrade RAMPS

      Here is the link to this module

      https://www.ebay.com/itm/3D-Printer-...53.m2749.l2649

      I do have a question

      Do I put the print heat element controller first then the voltage regulator or do I put the voltage regulator then the heat element controller which way would be better and WHY

          I want to control the heater element to run off of a 20 volt battery power

          I tried to use the controller board off of switching power supply minus the switching power supply portion of it

          Well this would power the ZD-917 controller board ok but the it would not control the heater element the mosfet was turn on fully on and blew the mosfet and burn the heat element out

          My guess is that some how the switching power supply was sending a signal to ZD-917 controller to control the mosfet

          I thought about trying to hack the switching power supply module board again but I have no way to get another one easily

          The reason I tried this was because I had one board that the board was having problems powering the Desoldiering gun

              Here is the test data that was done

              The heater element with no controller 8 amps @ 12 volts

              The switching power supply ( 30 volts @ 10 amps maximum ) that I was using the voltage would not get any higher than that but I can not leave it running like that very long because the heater element glow very bright and then burn out

              One note the Desoldiering gun and the soldering iron have very smilier results the soldering iron heater element amperage is a little lower

                ah, so your trying to run the desoldering unit off 20v dc?

                  Yes that is the plan

                  I am not worried about the suction pump running on 20 it will just run faster and give more suction

                  The problem is the heater element

                  controlling it safely and the results be repeatable and be reliable as is when running of 120 volts ac

                  Why I am trying to build this setup is because there are times when I have to repair a soldering joints on a machine controller board

                  and if I had this battery operated setup where I could do this repair at the machine then I would not have to take the item completely apart to repair it

                  also most our machines do not have 110 volts easily available and not always an outlet near the machine

                  Here is a bigger reason I wanting to this is to see if it can be done and it works correctly

                  Here is cost that I encounter so far

                  ZD-917 Controller ( for one unit) $15.00 plus $5.00 for shipping
                  Voltage Regulator DC 4-40V $4.00 free shipping
                  3 D print bed heater element controller $7.00 free shipping

                  If I get this setup to work correctly

                  I will post on this forum
                  I will show photos of what the inside the unit looks like
                  How it was put together
                  What I had to do to make it work right

                  So all together its about $26.00 and two broken unit ( ZD-915 and a ZD-916 ) case and other parts from the broken units

                  This has been an ongoing project for a long time I have tried different ways of controlling the current of heater element and nothing has work correctly so far

                  I want the ZD-917 to control the temperature of the heater element so I can still see the set temperature of the Desoldiering Gun / soldering iron temperature and see the current temperature is at the same time

                    it should run at 20v,
                    i suspect the problem is the DC, most soldering stations use zero-crossing switching - dc has no 0 point so the switching will latch on or off.

                      I figured it would have to be something like that

                      I posed the question earlier about which should go first the voltage regulator or the 3 D heater element controller or would it make a difference which one is first

                        just look at the circuits on the controller - look at how the triac is driven and look for any thing connected to ac other than a rectifier.

                          UpDate

                          The 3 D printer heater element controller will power heater element with no problem
                          I have to change the resistor for the optic sensors because the turn on voltage is about 9 volts surface mount resistor value ( 103 )

                          I need the turn voltage need to be 3 volts

                            So based on your measurement, the heater draw 8 A @12V, that means it has 1.5 Ohms (12V/8A) resistance, so when 30V is applied to the heater, it will draw 20A (30V/1.5 Ohms), so if your power supply can supply 30V then the power will be 600W! instead of 96W at 12V. No wonder it burns up, I am surprised the power supply did not go into shutdown.

                              This power supply regulate the current and voltage it is a bench switching power supply so if you try to pull to much current it lower the voltage

                              I have the voltage set at 20 volts

                              The voltage drops to 12 volts @ 8 amp

                              If the voltage is set for 12 volts

                              The voltage is about 10 volts @ 5.5 amps

                              Even with this setting the heater element will start glowing it just takes longer for this to happen

                              I probably going to set the Voltage (PWM ) Regulator to maximum of 5 amps ( which is recommended ) to 3D printer heater element controller and the ZD-917 controller keep heater element from glowing

                              One note the voltage regulator module has a maximum rating of 8 amps and it will not let you pull more than about 7 amps ( at least from the testing that I done with it so far)

                              Here is the data sheet for the buck regulator IC chip


                              One note there is a mistake on this data sheet for the output capacitor it says 1000uf @ 25 volts

                              It should say 1000uf @ 50 volts

                              Step-down power supply module DC4-40v to DC1.25-36v 8A 200w adjustable XL4016E1 DC-DC DC voltage regulator buck module

                              Buck chip: XL4016E1
                              Input voltage: DC4-40V
                              Output voltage: DC1.25-36V
                              Maximum power: 200W
                              Output current: max 8A (long operation, recommended 5A)
                              Conversion efficiency: 94%

                              This is the plan let’s see if I can get it to work that way

                                the heater element is 80w @ 24v
                                i hope your not powering the thermocouple instead!

                                  ZD-917 Controller ( for one unit) $15.00 plus $5.00 for shipping
                                  Voltage Regulator DC 4-40V $4.00 free shipping
                                  3 D print bed heater element controller $7.00 free shipping

                                  So all together its about $26.00 and two broken unit ( ZD-915 and a ZD-916 ) case and other parts from the broken units
                                  I can not seem to add very well

                                  The total is really about $31.00

                                    I will check this just to make sure that this is not the case

                                    When I have had the temperature sensor error on the screen before the heater element would glow very brightly and if you did not catch early enough it would burn out the heater element

                                    Thanks

                                      Yes the label says this

                                      However the switching power supply voltage version output is 18 volts
                                      On the transformer version the ac voltage is 20 volts

                                      So what up with this

                                      So is 80 watt for real or is this some what ( more or less ) than this

                                        Desoldiering gun

                                        This is the setting for the voltage regulator module the voltage at the heater element is going to be different

                                        So if I want to get the wattage to be 80 @ 20 volts then I need to set the maximum amperage to 4

                                        Soldering iron

                                        So if I want to get the wattage to be 60 @ 20 volts then I need to set maximum amperage to 3

                                        At least that what I have come up with

                                          Replacing the WiFi module on a vacuum cleaner iROBOT i7
                                          by AlexVG
                                          Hi,
                                          I have had an iROBOT i7 with a camera error (error 68) version REV M, year 2018.

                                          I bought a liquid damaged Mainboard with WiFi module, from the same vacuum cleaner, but a different year and a different version (REV G).
                                          (This board does not respond, only the LEDs light up in a circle.
                                          The liquid damage is catastrophic and restoration is impractical).
                                          (I bought this board to get the WiFi module and camera).

                                          The boards are completely different in the installation of elements, even the connector for the WiFi module is different.

                                          If...

                                          TOSHIBA DLP 52HM95 How to reset timer module on bulb
                                          by repair-it
                                          I replaced the bulb only on my Toshiba DLP The bulb is a TB-25. This is the first time I've done a bulb only replacement. Supposedly there is a timer module that needs to be re-calibrated or reset. I don't know where the module is located. I see some vendors selling the bulb with the housing stating module included which leads me to think the module is located inside the enclosure the bulb mounts in, but I didn't see it. Maybe it's inside the plug attached to the bulb?

                                          Anyway - I am seeking information on how to reset this so called module so that the lamp will operate. Apparently...

                                          70mai Dash Cam A510 - help identifying connector on camera module
                                          by m1ch43lzm
                                          Hi everyone
                                          I have a 70mai Dash Cam A510 which failed after about 3 months of being installed in my car, likely due to heat, i got it from aliexpress so no point in trying to return it for warranty (and shipping it back would cost me almost the same as a new one from ali)
                                          The camera would boot loop showing 70mai logo on the screen, sometimes it would boot fine then the live view would freeze or display purple lines

                                          I already took it apart, and found out that the camera boots fine if i unplug the camera module from the main PCB, sometimes "playing" with the connector...

                                          Light that has a bug zapper in bottom section of light fixture the LED light module took a crap but the zapper still works
                                          by sam_sam_sam
                                          So I got the bright idea to remove the LED light module from the fixture and put it on top of another enclosure and keep using the zapper

                                          The removal of light module was a successful and now I just have to cut a hole in the enclosure and put a power cord that has an on and off switch on it

                                          You are lucky to get about two years of service out of one before the LED module starts flicking and just stops working because it is mounted on an aluminum plate and these are hard to solder on it and it is not worth messing around with them and especially this one because it has line...

                                          i have a 2017 volvo that i upgraded the stereo in but the week link now is the SBC codec the head unit uses to transmit audio. i took the unit apart and we have a UGKZ2 combo module with a CSR8311 bt chip. after some research it is my understanding that ALPS made another combo module that used the CSR8350 chip. this chip is capable of aptx. https://vehicle-electronics.biz/cont...s-alps-modules

                                          my question is, would it be possible to swap out this UGX module as plug n play? what about replacing the CSR chip itself? any idea where to get either?
