Fuck you microsoft and fuck you edge

I got updates to windows 10 on 11-14-2023 kb5032189, kb5032005, and servicing stack 10.0.19041.3684. not trusting microsoft I opened edge and checked that certain webpages for local equipment I have that MUST use internet explorer were not messed with. found that of the 5 of them, 4 were removed from internet explorer mode and had to be added back. fuck you microsoft, I'm not some newb who doesn't know better. If I have sites that open in internet explorer mode then those sites only work right in internet explorer mode because they rely on active-x apps and there is no updates for them. I will continue to use them until the devices fail. mind your own business microsoft.

I suspect servicing stack 10.0.19041.3684 is the culprit, as every time I get one of these something gets  fucked up, or changed to serve heir microsoft.

Accessing Q-see QR474-1 4 channel DVR remotely

If you have a Q-See QR474-1 DVR or some other Qsee DVR from before they went out of business, and you want to access it remotely from your phone.

You can do it using the Onvier APP. These are not detailed instructions.

add a new device manually. select generic RTSP stream.

name the device.

add the URL in this format:

rtsp://xxx.xxx.xxx.xxx:554/ch1/0

the X's represent the IP the camera is on.

Channel 1 is ch1, 2 is ch2, 3 is ch3, 4 is ch4.

the zero on the end is the stream, 0 for master 1 for the lower quality sub stream

put in the username and password and hit test. if it works it should tell you it succeeded. 

you will have to do this for each camera channel. Same for accessing it externally once you open the 554 port on your router/firewall and point it to the DVR.

also if your Q-see HD DVR does not record motion even though it's turned on and scheduled, it appears that 1 or both send email and ftp upload have to be enabled for the camera. Email and FTP do not need to be configured but for some weird reason it won't record if they are disabled.

if you click save and the screen does not look like this with the channel number highlighted in green it will not record that channel. if you set everything like in this image and it still does not record motion then go in to maintenance, load default, and select alarm, and then click save.

Uniden Bearcat BC296D LIPO/lithium ion battery mod

For many years I have been trying to find a solution to the atrocious BC296D Uniden battery pack (BP120 / BP150 / BP180 / BP250). Other battery packs that held normal AA batteries would not fit. The garbage nicad/nimh battery tech made replacing the rechargeable batteries with something better (like Lithium ion) difficult. single cell lion bats put out a voltage of only 4.2v max, lower than the low battery voltage of a nicad battery pack.

most lion/lipo battery chargers only charged the battery and did not have an output voltage connection AND also would not fit inside the battery compartment. They would also require some kind of boost converter (taking up more space). The boost converter would increase the output voltage of the battery to at least 6vdc

Recently my intermittent (but relentless) searching finally found a combination of components that would fit in the compartment WITH a battery that was the same mah or higher than the nicad packs AND would have a service life longer than nicad/nimh.

for this mod you will need:
1 - J5019 combination 1S single battery charger/boost converter with built in BMS.

1 - LIPO battery pack measuring 10mm X 40mm X 50mm (thickness x length x width) or some type of lithium ion battery that will fit in the compartment with the other components and be of sufficient mah. the lipo or 18650 must have a protection circuit. most lipos do, 18650s usually do not.
1 - DC barrel connector socket that will fit in the narrow confines of the side of the case.
1 - 5v-8v DC power supply.

The resolve to alter your scanner.

I found a DC socket that just fit, carefully measured everything and found a LIPO battery that was 2400mah that also just fit. The boost converter/battery charger fit perfectly as well.

I used 3M 100mph double sided tape to hold the battery in. the BMS has 2 LED's on it a red one for charging and a green one for charged. it has a tiny POT to adjust the output voltage. I set mine to 5.99 volts because it was finicky. I reused the old battery packs connector.

the board is held in with hot glue. the BMS can charge at up to 1 amp. You can run the scanner while it is charging. I have not noted any interference from the boost converter (yet).

You cannot use the original power plug with this mod.

Dell UPS 500W Charger Fault or battery disconnected

Dell UPS 500W reports a Charger Fault/failure or battery disconnected.

Pull the batteries out, take the plastic case off, disconnect the batteries from each other and check voltages. if any battery are 1 volt or more different from the others:

One battery reads between 12.5 to 13.1 volts and the other reads 11 volts or lower the lower reading battery may be bad. Try charging it on a 12 volt battery charger for an hour or 2 if it goes back to the original reading or quickly goes below 12 volts it is bad.

Replace both batteries batteries.

On the UPS clear the error if it does not clear itself. Press and hold the left arrow button, then go through the menu until you find the option to clear the error log and reset error condition.

QT428 System Initializing boots to nothing

I have a Q-see Qt428 it belongs to my brother. he reported that after a power surge it would not start up properly.

unit is 12 years old. I did some checking and found that every single capacitor on the board is bad. So I replaced them. same results won't fully start up.

tried a different power supply. same results. replaced HD no dice. after about 6 to 8 hours of searching the internet I stumbled on an ebay review that states the devices can be recovered by putting firmware on a USB stick and turning the unit on, the device would supposedly load the firmware. Problem is I don't have any firmware.

contacted the reviewer and had to play 20 questions, he pointed me at a supposed firmware file which when put on usb stick and placed in the unit, got accessed but did nothing more. I contacted "q-see" and have not yet heard back from them.


this device gave my googlefu a massive work out. I went on a wild goose chase for firmware (which ended up NOT being the problem).

Every single electrolytic capacitor in this device was bad, very high ESR to not even being seen by my capacitor testers. how it was working at all I do not know.

Before 

                                                                                   After

Replacing the capacitors did not change anything.

So in my searching I found little tidbits of information here, and there like:

this unit is the same as a TVT TD-2308SE which led me to TVT's site where I found GARBAGE instructions on how to access the linux OS on the unit through ye olde fashioned RS232 com port. the purpose of which was to upload firmware which their site had none of.

Now of course all my new computers don't have a COM ports so I had to dust off an old DELL laptop I keep for such instances. BUT the unit has a TTL com port and cannot directly interface with RS232. luckily I had a TTL to RS232 converter I got for another project.

of course there are no pinouts on the main board of this unit as to what is what. but I determined where +5v and ground were. 


 said a hail Mary and plugged it in. 

just friction fit and did not push it through all the way.

next I consulted the worthless TVT doc which had zero information on the what settings to use. It ended up being 115200bps n,8,1, software handshake.

as soon as I put that in to putty and connected I saw a prompt and something constantly repeating about there being no more space. I spent a good hour trying to follow the instructions to update the firmware with the supposed firmware that the ebay reviewer directed me to. It never worked.

after a crash course in linux commands (I'm a Windows and DOS guy) I went to plan B trying to fix the file system since it appeared the flash memory was full. I finally located a TMP folder and noticed a 490k file with a name (similar to) zxzycxwv or something like that (probably a random name). I deleted it, and the error message about no more space disappeared. I restarted the device and BOOM it started up normal and the only information lost was the time and date (dead CR2032) battery.

Editing or removing security from a printable PDF

If you have a (secured) PDF and you want to copy text from it, perform OCR, or for whatever reason remove security, AND it can be printed. do the following:
Print the PDF with the Microsoft XPS Document Printer.
Open the .oxps document with XPS viewer.
Print the document as a PDF (if you have that capability).
document now unsecured. OCR or whatever.

There may be weird issues if there are watermarks.

microsoft edge hassles and problems

It appears that my microsoft edge was never upgrading since I got my computer. the problem appears to have  been that a zero length file named "temp" (with no security) in the folder C:\Program Files (x86)\Microsoft\Edge was causing the problem. added myself to the security (full control) and deleted it. ran the edge install and BAM I could update it. Edge installers and updaters were to retarded to tell me the exact folder name.

Then microsoft edge decided I needed to see ads and garbage on new tabs. I installed the add on/ extension Custom new Tab which edge immediately disabled. I then enabled it and set it to what I wanted. Then Edge decided that ALL attempts to open internet explorer would be redirected to edge I don't want that. the following fixed that issue.

You can stop Internet Explorer to Edge redirect by disabling the IEToEdge Browser Helper Object (BHO) from the registry editor. Here’s how.

  1. Open the registry editor.
  2. Paste the below path in the address bar and press Enter.
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Ext\CLSID
  3. On the right panel, double-click on the “{1FD49718-1D00-4B19-AF5F-070AF6D5D54C}” value.
  4. Change the Value Data from “1” to “0”.
  5. Click on the “Ok” button.
  6. Close the registry editor.

 all this for a browser I won't be using.

error messages I received when trying to update or install:

An error occurred while checking for updates: Check whether you have free disk space and permission to install software. We couldn't create a temporary directory. (error code 7: 0x80040902: 11 -- system level).

Rsrteng DM-SCD405I5AP-V04-E IP PTZ camera RTSP stream not working with VLC

Rsrteng cameras are rebranded Huisun cameras. do not select english on the website, open in chrome and have it translate. If you select english you get a different website. Either way there are no useful downloads for this camera.
the rtsp stream URL for VLC is:
rtsp://xxx.xxx.xxx.xxx:554/PSIA/streaming/channels/101 

use your IP in place of the xxx's.

Issues with the cameras:

Will show your password sometimes when logging in from a browser (reboot camera to fix).

Unable to get NFS to work, unknown why no errors generated.

Be very careful handling the unit, very difficult to remove and install screws in cover over SD card. Can easily rotate and possibly mess up gears.

Iif you leave the video open in a tab and then go to another tab the video will stop and you have to click on something else and then back to live. click on sub then click back on live

slow network transfer rates copying or moving small files QNAP Synology

Do you have a QNAP NAS?

can you copy or move very large files with gigabit speeds like around 100+MBps? (megabytes per second).
but when you copy small files the transfer rate drops to 10, 5, 1, or even 0kbps (kilobits per second).
sometimes sitting at zero for minutes?
If you use the app CX file explorer on your phone and the transfer rates are way higher than on your computer them the problem is on the computer.
have forums been telling you that this is normal? WELL IT'S NOT! they just don't know what to tell you.
I'd like to be able to give you an exact reason why this is happening, but it may have multiple causes.

Here's what I suggest:
check all cables and devices support the speed you are trying for.
check your MTU, is it the same on all devices?
drivers, updates, lan card settings, yadda, yadda, yadda!
check SMB versions on all devices.
disable encryption.
disable any compression.
check share permissions.
disable server signing.
if joined to a domain is the device still joined (this was an issue for me).
disable anti-virus scanning the NAS drives by letter and UNC (also an Issue).
If .jpg transfers are slow are thumbs.db accessible and changeable?

I read somewhere that creating a new profile can fix some NAS issues. in my case I logged in to my computer as a user that had never logged in before and mapped a drive. then logged out and back in as me and suddenly the speed issue is gone.

I did all of the above to get my QNAP transfer rates to what they should be.
My synology was having issues but not as bad. disabling virus scanning fixed the issue for it.

Windows 10 Strange problems recently appear caused by microsoft ransomeware protection

 recently I had some strange issues crop up that made no sense, and if they generated errors at all they also did not make sense.

First was this one: https://robert.guildig.org/2023/03/nero-burning-rom-does-not-see-blank-or.html

the next one happened this morning. I was making a backup to blu-ray (which worked fine).
I (being a bit old school) went to a command prompt and attempted to issue this command in a folder the path of which is c:\users\username\documents\backup

command was as such dir /s d: > backup24.txt
simple right?
no! it comes back with file not found (I don't remember the exact wording).
What the heck! file not found?! it should just create the file.
now I think I'm losing my mind because I've been working on computers since dos 2.11 I've done this MILLIONS of times. after confirming I haven't suddenly developed dementia (by googling the command), I try creating the file in the GUI (which works) and run the command again.
the results:
not enough space on the disk
there's 759 gigs free!

Remembering what happened yesterday I go in to ransomware protection and sure enough CMD.EXE is blocked from accessing that folder and a bunch of other folders (most of which I never use).

I unblock it and the command works perfectly.

If the command had come back with "access denied" I would have dealt with it differently, but the unconventional errors that did not match the actions being prevented was not helpful.

I don't know when Ransomware protection was installed. my googlefu says possibly sometime in 2019, but that it was not activated by microsoft until recently (because I didn't activate it or even know about it). All this worked in september 2022.

Nero burning ROM does not see blank or any disks in burner

nero 10
problem started sometime after 9-23-2022 (last time I burned disks).
same Blu-ray/DVD/CD burner.
same media I have always used.
Reads all media just fine.
windows shows disk changes.
windows shows when disks are blank.
connect an external burner and same issue.


nero 10 suddenly stopped seeing the drives at all.
uninstalled nero 10.
purchased and installed latest version of nero 2023 25.0.1.4.
Nero now sees the drives.
place empty disk in drive nero does not see disk, but windows does.
updated firmware on drive. rebooted, nothing changed.
uninstalled drivers for drive, rebooted, nothing changed.

tried burning with windows (never did that before always used nero) takes forever and doesn't complete because it says I need 816 PB and disk is only 4.7GB or 25GB. data is 4.3GB.

contacted Nero and they were no help. found this article but not by searching for the symptoms. 

windows 10 ransomware detection was the problem.
you have to go in and allow blocked nero apps.

there was no warning or popup that a block had happened it just suddenly stopped reading or seeing disks.

very frustrating.

Magix Vegas not responding when splitting or deleting video while it plays

I have vegas 18.0 build 527 every time I split while I am playing a video or hit delete while a video is playing vegas would freeze or be not responding.

what worked for me to make this go away was to go in to Options/preferences/file I/O and put a check mark on Enable Legacy AVC decoding. now I can split while playing or hit del without lock up.

Failure mode of an APC Back-UPS 1500

If you own an APC Back-UPS 1500 UPS possible model number BN1500M2 and have experienced a failure with Error F04 and possibly Error F02 with the sound of arcing coming from the unit the problem may be the transformer. It appears the units are shipped with transformers that have copper coated aluminum wire and the connections have failed or broke free. If you have unit and it is in some critical role you may want to take it out of service.

see this video for details.

Security First 5005 camera wire pinout

Security First (which seems to be no more) 5005 cameras use RJ11 6 pin connectors. Their pinouts are as shown in this diagram.

The wires in the connector and 100 foot cable are Red white black black. pin 5 may be yellow in the 100 foot cable. the colors in the diagram are from the camera.

the wires internally to the camera are Red white black yellow.

Information I can find states the red wire can accept 12-15vdc which means that it probably has a voltage regulator in side and is compensating for the massive voltage drop through 100 feet of very small wire.

I have no other information than what is presented here.
