How to Test a Relay with a 9V Battery

How you can test if a relay is functioning properly?
To test the relay, you only need a 9V battery for the most basic test.

 

Relays have 3 kinds of terminals, coil terminals, NC and NO terminals.
NC is normally closed.
NO is normally open.
The Coil terminals control the state of the relay. Closed or open.

NC is letting electricity pass thru the relay when there is no voltage and electric current flow across the relay coil terminals.
When the coil is energized, the NO terminals, close and let electricity flow.

Just place the battery on the relay terminals that are connected to the relay coil.
When you place the 9 volts battery on the relay coil terminals, the relay will click.
Try the switching the + and – positive and negative terminals if the coil doesn’t work.

It supports SATA2 (SATA II) and SATA 3 (SATA III).

I have tested this enclosure with the WD Mycloud. Tried to connect it to the USB 3.0 host port of the My cloud and it DID NOT WORK.
It may be possible to force the drive to be mounted. Tried ssh but couldn’t mount the drive.
Also I did not format the HDD to check if after formatting the WD Mycloud will see the drive.
If you have this hard disk dock and it works with the Mycloud write bellow in the comment how you did it! πŸ™‚

If you want this for Mycloud backups it might be better to look at other enclosures.

The enclosure will power-down the hard disk after approx 5-10 min. of inactivity and it will power-up the hard disk once the drive it’s accessed. This works perfectly.
I refer the HDD to be powered down when not in use to reduce power use and reduce heat and wear in the summer.

Sometimes too many power-up power-down cycles are not good but in my case it will be for backups so it won’t be accessed all the time.

If you want to ask anything about the enclosure, just ask in the comment section bellow and please subscribe! πŸ™‚

Samsung 850 EVO speed test on SATA II ports

Today we unbox, install and speed-test the Samsung 850 EVO SSD drive on an old SATA 2 ( SATA II) port in my old but good 10+ year old motherboard… the Abit IP-35 πŸ™‚

Watch our whole video of the unboxing, installation and testing including real-time Windows 10 startup test on an SSD.

Samsung 850 EVO speed test on SATA II ports video

Testing the Samsung 850 EVO

V-NAND SSD drive 2.5 inch size that fits both in laptops and in a desktop PC.

When installing the SSD in a desktop computer, you might need a HDD bracket adapter from 2.5 inch to 3.5 inch HDD bay. If your case has a 2.5” HDD bay you won’t need any adapters.

This 2.5” HDD has standard SATA power and data connections.

It has mounting holes on the sides and also on the bottom of the drive.

The SSD shown here and in the video is the 500GB version.

Specifications:
Make: Samsung Electronics
Model: Samsung 850 EVO
MZ-75E500
Type: Solid State Drive
Interface: SATA III (SATA 6Gb/s), compatible with SATA II (SATA 3Gb/s) and SATA I (1.5Gb/s)Β  Interface

Up to 540 MB/sec Sequential Read
Up to 520 MB/sec Sequential Write
Random Read (4KB, QD32):Up to 98,000 IOPS Random Read
Random Read (4KB, QD1):Up to 10,000 IOPS Random Read Random Write (4KB, QD32):Up to 90,000 IOPS Random Write
Random Write (4KB, QD1):Up to 40,000 IOPS Random Write
Memory Speed: Samsung V-NAND 3bit MLC 512MB LPDDR3
Controller: Samsung MGX Controller
Supports: Trim, AES 256-bit Full Disk Encryption, S.M.A.R.T., Garbage Collection.
Reliability (MTBF): 1.5 Million Hours (MTBF)
5 Years Limited Warranty or 150TBW Limited Warranty

Full drive specifications: here

SSD performance when used in best conditions – SATA3 can achieve the bellow speeds but we will test it on SATA 2.

If your PC is running SATA in IDE mode you should change to AHCI mode to increase performance.

Install the Samsung Magician app/program and it will tell you if Trim and AHCI are enabled.

Normally when changing from IDE to AHCI you would need to reinstall the Windows operating system but there is a way to avoid that.

 

Simple instructions:

  1. Press WindowsKey+R
  2. Type “regedit” without quotes and press enter,
  3. Navigate to this registry key:Β  “Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\StartOverride”
  4. Find the D_WORD key named “0” and double click to edit it’s value
  5. Change the value from 3 to 0
  6. Press ok, close everything and restart the computer
  7. Go to bios and change SATA mode to AHCI (different depending on your MB manufacturer)

Start windows and check in Samsung Magician that the AHCI is reported as enabled.

Once that looks good it’s time to use the Data migration tool / application to clone the old hard disk on to the new SSD.

Doing this helps you save time but watch carefully in the video that there are some potential problems that you can avoid if you follow the steps.

Once cloning is complete, the SSD will become the system drive.

Tested the SSD on SATA2 and even though the sequential read spead is limited by the SATA II interface bandwith the random access speed is much much greater that what the old HDD was able to provide.

In the test we reached more than 280MB read/write speed and in the real world that should make it worth upgrading to SSD even if you don’t have SATA 3 (SATA III) ports on your motherboard.

The 850 EVO is much faster than our needs but paid less for it because the new 860 EVO was released… Could have used a slower drive because the interface is the bottleneck here but this was the cheapest 500GB drive I could find locally at the time we bought this.

If you thing about upgrading to SSD, do it! πŸ™‚

Brand doesn’t matter, any SSD will be faster than your old HDD!
Just think about how much space you need, and then find the cheapest from any of the top 10 manufacturers.

Write a comment bellow if you upgraded your PC storage and are excited as I was when saw the speed of this thing! πŸ™‚

Broken SATA Connector on Motherboard Fixed

  1. Did you Break a Β SATA Connector on your Motherboard?

Showing you how to fix a SATA connector when it breaks from the Motherboard (MB).
When you pull the SATA cable without pressing the release pins before, the connector on the Motherboard can come out with the sata cable.

If the SATA pin header connections are still intact, you can fix the SATA connections with this trick.

You must try this only if you have experience with fixing small parts.
This needs very steady hands and a lot of patience.
You should not press the SATA connector plastic housing but just let it slide down on the pins.

All SATA pins must align with the sata connector housing to be able to fix this.

Use Epoxy glue to secure the sata connector on the Motherboard.
Do not use super glue! I have used superglue before and it doesn’t last because there is mechanical tension and the Motherboard flexes slightly when you press down the SATA cable on the connector.

Fix Noisy Oven Fan & Replace Oven Light

Showing you how to fix the oven light and fix a noisy oven fan.
Showing this easy fix on an Ariston Hotopint oven but most ovens are built the same and this solution can be applied to many oven makes and models.

The fan makes a loud noise sounds like metal touching metal and it sounds like the motor in the oven has failed and needs to be replaced but there is a chance that you don’t need to replace the motor but just check the motor’s fan and see if the fan became loose.
If this is the case, all you have to do is tighten the nut that holds the fan on the motor.

Also changing the oven light bulb.
Before changing make sure that the light bulb is the problem and not something else.
If the light bulb has it’s filament broken, you know that bulb needs to be replaced.

The light bulb is a Philips
25W, 300 degrees Celsius, 230v 240v
if the light bulb cover is missing, you should replace the light bulb cover so that the light bulb does not burn again.
The light bulb cover prevents grease splashes from touching the light bulb and damaging it.
You can use it without a cover for a while, temporarily.
Our light bulb cover just broke one day.

Replaced it with a 15W bulb because I couldn’t find a 25W bulb.
It works perfectly now.

Thanks for Watching and reading.

Cleaning Clogged Print Head in Inkjet Printers

Cleaning a clogged print head in inkjet printers is easy to do, just need to follow a few steps.

You need a syringe, window cleaner liquid, Isopropyl alcohol 70% or higher and distilled water.
Oh and a lot of patience.

Also showing how to diagnose transport and pickup roller problems in the inkjet printer and fixing them when the printer does not pick-up paper in the paper feeder.

This is a Brother printer, model MFC-215C

First video, how I found it

Second video, Clogged print head cleaning

It’s a multi-functional printer, scanner, printer, copier, and fax machine.

How to clean a clogged print head in inkjet printers.
Cleaning a clogged print head can be done in several brands of printers.
You can apply this method in inkjet printers that have the print head as a separate unit from the ink tanks.
You cannot do this on printers that have the ink containers and print head as one unit as HP does. For that we have uploaded another video.
This is applicable for Canon, Epson and Brother printers.

VW Polo 2003 9N Heater Blower Motor Noise – FIX

VW Polo 2003 9N Heater Blower Motor Noise.

How to cleaning or replace a noisy VW Polo 2003 9N heater blower motor.

Heather blower (HVAC) motor was making lout noise at speed 2, 3 and 4.
While the blower motor was running the dashboard was vibrating because of it.

 

Video – VW Polo 2003 9N Heater Blower Motor Noise

Showing how to remove it from the car, ckeck and clean it.
If the noise is still present you can replace the motor but i’s worth trying to clean it before doing that.

Also showing the thermal fuse of the blower motor.
If this fuse is blown, your ventilation will work only on speed 4. On the other speeds the motor will be off.

That thermal fuse can be blown if the motor is really going bad and doesn’t sping freely, thus consuming more power(drawing more current).
That fuse is a safety measure, replace it if needed with the same specification. DO NOT replace it with a plain wire!!

 

Maxtor D3 Station – 4TB External HDD Unboxing and Test

Maxtor / Seagate D3 Station – 4TB External HDD Unboxing and Test
This external hard disk (HDD) comes with a large variation of power adapters.

In the box:

  • HDD
  • USB 3.0 data cable
  • Power supply and socket adapters
  • Manual, warranty, blah blah…

For the drive to spin-up you must connect power and the data cable. If only power is connected, it will stay in sleep mode.

During a transfer speed test the drive just stopped working and an error message popped up about the drive being gone.
Checked the windows event log and that confirmed, the drive dissapeared on it’s own and the event log had errors related to the HDD.

After a bit of troubleshooting I’ve realized that the USB 3.0 extension I was using was ‘not good enough’.
Connect the HDD directly to the USB port in the computer, no cheapo USB extensions and you’ll be alright. πŸ™‚
