    Tips And Tricks

    So, I've been reading threw forums for the past two weeks soaking up at the great info I can find, but I'm surprised I have not found a good tips and tricks yet! If there is one and I haven't came across it, we'll my bad. So here are some I've read and enjoyed!

    1. The good old current limiting light bulb! Simple 40-100 watt light bulb in series with the hot!

    2. Small cfl light bulb to test inverter outputs.

    3. Isolation transformer on scope of equipment.

    4. Home made EEPROM reader/writer

    5. To be discovered!!!

    Seems like some of the tv stuff once you read it goes in and out. Wether it's because it seems like the usual (replace bad caps) but others just seem to stick.
    So if anyone would like to add their tips and tricks it would be great! I feel it would be good for any new people and also myself! Oh and btw how do we get a smilie in the list that is holding a Canadian flag???
    Thanks for the time!

    "Isolation transformer on scope of equipment." it should be isolation transformer on the unit you are testing (Notes: the Neutral output of the isolation transformer should not be connected to the safety ground, but the outlet still must have safety ground that is connected to the incoming AC safety ground.
    Also should always use AC outlet with GFCI.

        Just for clarification Jonesy123, in#3, were you referring to using the isolation transformer to isolate an oscilloscope?

          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...

          LGA 1700 Socket Replacement Tips & Tricks
          by AJ847.63e
          Hi All,

          Just wanted to see if I can get some advice on techniques and equipment I should use to try replace the socket on a Gigabyte H610M h v2ddr4 I have.

          I was planning on using a heat mat I have that's used for phone, tablet screens, as a base heater than use hot air with a square nozzle on top. Yes I should get a proper preheater but I'm not in the position to go spend 300+ bucks on something I will use every 6 months if I'm lucky. Next expense I need to get is a decent programmer like the RT809H but again it would get used infrequently so hard to justify.

          LUMIMAN Smart Bulb IC ID?
          by ezenia
          Hi,

          I have a LUMIMAN Smart Bulb that suddenly stopped lighting one day. The bulb is still detected in the app, but won't light. I've probed around and nothing seems to look off with any of the diodes, caps or resistors. The Bluetooth/Wi-Fi module seems to be working as it's still detected in the app. I even tried deleting and re-pairing the bulb (it didn't light, but I was still able to follow the pairing instructions), it re-paired fine, but still no light.

          In diode mode, the LEDs all light up when probed so I'm guessing this means the LEDs themselves are OK. I was expecting...

          isolation transformer from two 240/12, wiring?
          by harp
          When is talk about making isolation transformer on poor-man way, always I see schematic 240/12-12/240.
          So, I wonder, is this wiring from my attachment it work, bringing some good feature or it is bad idea and why?...

          Original Xbox 1.0 PSU: Foxlink FTPS-0002 Rev. B. — 12 V low, 5 V high — transformer?
          by ohren
          Hello!

          I'm looking at an original Xbox PSU: Foxlink ftps-0002 rev. B. The 12 V output is too low, and the 5 V output is too (?) high. Unfortunately I don't have an oscilloscope but only a DMM for diagnosis.

          Measured voltages with no load:

          After rectifier diodes
          12V: 6.17 V
          5V: 5.67 V

          Secondary transformer pins AC measurement (really don't know if this says anything)
          12V: 2-2.5 V
          5V: 1.04 V


          I also have another (working) Xbox psu from Delta. The same measures there, in order, being: 10.79,...
