Panelization in EasyEDA

The instructions for panelizing a board in EasyEDA are absolutely terrible and confusing, they lack any useful information. 

In easyeda select tools then panelization.

Select the number of rows and columns BUT keep in mind that their machine can only accept a minimum size board of 7x7 Centimeters. So you will need to select a minimum number of rows and columns that meets or exceeds this number. as an example I have a board they is 18.75x8.5 millimeters. in order to meet the minimum requirements of panel size my board needs to be 4 columns by 10 rows high. The minimum column and row spacing is 1.6mm. I do not need boarders.

Originally based on the instructions (I found) I thought I had to account for the board size when selecting the spacing and put in 18.750 for columns and 8.5 for rows which got me very strange results.

There is still some confusion on whether you need to copy and fix the circuit to each board. it appears that you do not (JLCPCB will supposedly do this for you), but there is conflicting information about this on line.

Panasonic RE-7700 Automatic Tuning Stereo

picked this up from goodwill today for very little as it did not power on.

The reason it did not power on was that a small tab of copper or copper plated steel that actuated the power switch had been knocked off the switch.

in order to get the top of this unit off remove the screws circled in red, to get the bottom plate off remove the red and the green circled screws.

You will also need to remove this screw from the top side. I ended up drilling a hole through the plastic in order to get to it. You will definitely have to do it to put the screw back in.

The schematic is inside the stereo under the top cover. If yours is missing here is a very high resolution scan. Dial string instructions included.

Or you can download a pdf that contains it, and better printable copies.

Philips 800Lumens 8.5w 2700k LED light bulb failure mode

We purchased several Philips 800Lumens 8.5w 2700k LED light bulbs in January of 2017 from Ace Hardware the bulbs have a UL number of 3PM5. About a month ago one of them stopped working and I took it apart. I was hoping to repair it, but found that it was not possible due to how it was put together and because the small transformer on the circuit board had broken apart and fallen off the board.

Today another one started going out. it started blinking on and off. I replaced it and opened it up, I found that same issue the small transformer had fallen off the circuit board, and there was the smell of burned components, and an electrolytic capacitor on the circuit board had overheated and popped.

The bulbs were mounted in a ceiling fan light fixture that is open and pointing down at about a 45° angle. The bulbs are supposed to last 22 years at the ridiculous usage of 3 hours per day. The warranty was 3 years.

Everyone Was Kung Flu Frightened!

Today the wife and Mother-in-law decided we should go out for a drive. We headed to the north scottsdale/Phoenix area. On the way back we headed down Cave Creek rd. and since we were in need of some items we had forgotten to get on previous trips to the grocery store we stopped at a Fry's on north Cave Creek rd.

Here what it was like:
it goes without saying that there was no hand sanitizer or medical alcohol.

No bottled water

 No Bread

 No Canned Foods

No Pasta

 No Rice and Beans

 Not much in the way of soap

 and of course the one item that makes you invulnerable to viruses...

NO Toilet Paper!

Now the rest of the aisles were mostly normal. I figured that rich people would just order their stuff from Zanzibar and not worry about it.

LG's Scare mongering

Watch this video of Louis Rossman's evaluation of the scare mongering campaign by LG regarding 18650 batteries
#LithiumionBatteryCells, #18650, #StaySafeBattery

Way to blame the consumer LG!

How is not selling legit good batteries going to prevent this LG?

It is apparent from the video that LG thinks the average consumer is a complete moron.

It's too late there are tons of products on the market with consumer replaceable 18650 batteries. The cat is out of the bag. So instead of throwing gasoline on the fire how about finding ways to make LION batteries safer?

Rossman is right again.

Stop cats from chewing on an oxygen line

Purchase a small bottle of orange scented anti bacterial dish soap, and a bottle of Angostura orange bitters. if the bottle of soap is completely full use or dump out 1 or 2 tablespoons of the soap. Add 1 to 2 tablespoons of Angostura orange bitters to the soap bottle and shake. Using a paper towel or small rag pour a generous amount of the mixture on to the rag and run the oxygen line through it adding more soap if needed. The oxygen line should be slippery when you are done. Coat every bit of Oxygen line the cats can get to unobserved.

Repeat every couple of days. Add more bitters for stubborn cats.

Cats do not like the taste of orange, the anti bacterial agents also have a bitter taste to them, and the bitters contain bitter orange. The combination should keep them from chewing on the Oxygen line. I do not know if it will work for other animals.

 

Fixing the Hobbit Cartoon DVD

Some are aware that the DVD (and later releases) of The Hobbit (Rankin Bass) have a problem. Sound effects are missing from key moments in the DVD. Plate clinking in the beginning, The spider death sound, some of the sounds made by Smaug when attacking, and other sounds.

What I did was obtain the 1991 release of The hobbit on VHS. This version has all the correct sound effects but the quality of the video is not as good.

Later releases on VHS possibly have the same sound issue.

I had to rip the DVD version, then play that back and record it using OBS Studio.

I had to load the OBS MP4 file in to goldwave and pull the audio out to a wav file as Sony did not see the audio.

I replaced the DVD audio with the one I pulled using goldwave so I could have reference, and I had to align that audio to the DVD which was mostly easy.

I could not use the DVD ripped files as there is some weirdness from the VOB files that playing the DVD does not have.

I then loaded both videos in to Sony Vegas.

turned off the audio from the DVD and the Video from the VHS.

I split the VHS video at the silence in the fade in and out for the commercial breaks and realigned the VHS audio to the DVD video at each break.

the first part of the movie before the commercial break was particularly messed up, there appears to have been an edit in either the DVD or the VHS version.

Once I was satisfied with the alignment I re-encoded everything as a 720x480 mpeg2.

The results are pretty spot on.

Importing video from a Sony HDR-XR150 Camcorder without using PMB

I have a Sony HDR-XR150 camcorder and up until recently the only way I had to get video off of the camera was using Sony's PMB (Picture Motion Browser).

PMB is fine if you are Joe Average but for me it was sometimes very slow to import video.

I found that the reason it was sometimes slow was that if your video was larger than 2 gigs the camera breaks the file up. When PMB imports it, it somehow knows this and it re-encodes the video to a single file instead of just copying the files over. This takes as long or longer than it took to shoot the video in the first place. I don't care if the files are split as I can re-join them in my editing software. I decided to write a batch file to copy the videos over from the camcorder, and to make it even more difficult I decided to keep the PMB name format. What a pain in the ass that was. You can just copy the .mts files over and rename them manually to m2ts.

If you want to use this method you will need:
a batch file in c:\windows called imp.bat
a batch file in c:\windows called impmts.bat
a folder called c:\temp
the camcorder when connected through USB connect as drive L:
The destination folder of Z:\videos\pmb

or you can edit the batch files to whatever drive letters and locations you use.

The contents of the IMP.BAT file is:

set startdrv=%cd:~0,2%
dir %1 | find /I "MTS" > c:\temp\x.x
set /P finfo=set stripped=%finfo:~0,17%
for /F "tokens=1-8 delims=::./ " %%A in ('echo %stripped%') do set FileDateTime=%%C%%A%%B%%D%%E
for /F "tokens=1-8 delims=::./ " %%A in ('echo %date%') do set dirdate=%%B-%%C-%%D
if exist Z:\videos\pmb\%dirdate%  goto skip else
md Z:\videos\pmb\%dirdate%
start Z:\videos\pmb\%dirdate%
:skip
if exist Z:\videos\pmb\%dirdate%\%FileDateTime%.m2ts goto oops else
@echo on
copy %1 Z:\videos\pmb\%dirdate%\%FileDateTime%.m2ts
@echo off
:oops
del c:\temp\x.x

  The contents of the IMPMTS.BAT file is:

echo off
CLS
Echo Importing Files...
for %%Z in (L:\AVCHD\BDMV\STREAM\*.mts) do (
call c:\windows\imp.bat %%Z
)

It is quite probable that using 2 batch files is not necessary but I did it that way to fix some problem I was having.

The batch files work basically like this(if I remember correctly):
impmts looks to the location on the camcorder where the MTS files are stored and for each file there it runs the IMP.BAT file which sets the drive letter of drive where it started from (usually c:) to an environment variable called startdrv.

A directory listing of the MTS files is written to a file in c:\temp\x.x
information from that file is fed to more environment variables.
The MTS file date and time is retrieved and set to an environment variable FileDateTime.
The current date is set to a variable called dirdate.
The batch file then looks to see if the folder is already there, if it is it skips creating it, if not it creates it.
It then opens the new folder in a window.
It then looks to see if the new file it wants to write is already there if it is it skips copying that file from the camcorder.
If the file does not exist it copies the mts file from the camcorder to the destination with the correct name format of YYYYMMDDHHMM.mt2s
Then it deletes the x.x file from c:\temp
Control returns to IMPMTS.BAT and repeats until all files are processed.

There is not much error handling.

you may find strange characters in the batch file at the end of lines that are not in my code on this page, if those characters are there the files will not work right until they are removed. I am not sure where they come from and they are not always there. Just letting you know it might happen.

If you use these batch files and your videos are lost I am not responsible. They shouldn't be lost because it does not delete anything from the camcorder.

Usage is simple from a cmd prompt (not administrator) run impmts.bat "nameoffolder"

I cannot, and will not provide help on editing the batch files to work for your system.

Slow Transfers QNAP NAS on a Gigabit Network

For several months or possibly years transfer rates from my QNAP nas TS-231 have been very slow about 12.5MBps to 15MBps (that's megabytes per second). I have a gigabit network and transfer rates should be above 50MBps.

I won't go in to all the ridiculous things I tried based on other people having the same issue, here is what fixed mine:

After opening a ticket with qnap 2 months ago and dealing with their SLOW response times I finally got a resolution to my problem.

The last thing they asked me to do was to disable server signing. No explanation of what exactly they were referring to, no information on where to find this setting. nothing useful.

I spent a couple of hours googling how to disable server signing on a qnap with nothing useful being found. I tried editing the smb.conf (this appears to be where the setting is), but the qnap changed my settings back upon a reboot of the server.

after much more googling I kept finding references to server signing with windows, which led me to try something.

My qnap was set as an Active directory domain controller, I did that because I kept having problems getting access to my own files.

I turned off AD domain controller and of course that broke access to my files.

I also had to disable Windows ACL support since I could not access my files, take ownership of them or anything, I enabled Advanced Folder Permissions.

I did manage to join the qnap to the domain, something that never worked before. I do not know why it is working now.

I was then able to set permissions of my files in the qnap webpage and finally access them.

I noted that server signing is now disabled in the smb.conf file (not by me).

I tested copying files and wow look at that transfer rates of about 60MBps.

It only took over 2 months and countless hours googling the issue. Was it server signing? was it my qnap being a domain controller? not sure but it's working now.

EnGenius Wireless Access point stops working

If you have an EnGenius Wireless Access Point wifi that stops working properly and has to be reset frequently this may solve your problem. You may login to the device and everything appears to be fine yet nothing will connect to it or it may not even show as a device to connect to.

The cause:
Many EnGenius WAP's have a problem where after several days or even hours of use the access points are not freeing up some resource internally. I do not know exactly what. I found a forum post many months ago that explained it but I cannot find it again.

The solution:
Upgrading the firmware does not help and on some models they are End Of Life and updates are not available. You can put them on a timer that disconnects power for a short time every night when they are not used, or you can write a script that reboots them.

You will need:
TST10.EXE
A folder under C:\windows called script
put tst10.exe in C:\windows\script\
Create a text file for each device you want to reboot.
C:\windows\script\ecbcom.txt

the contents of the file should be:
x.x.x.x 23 replace the x's with you devices IP keep the space and 23
WAIT "Name:"
SEND "admin\m"
WAIT "Password:"
SEND "youradminpassword\m"
WAIT "cmd>"
SEND "reboot\m"
WAIT "cmd>"

Create a batch file in C:\windows\script called tst.bat
the contents of that file should be:
c:
cd\windows
cd script
call tst10 /r:ecbcom.txt

Create a task schedule to run and execute the tst.bat file at the time you want to reboot the access point. I tried the timer method but that was causing problems with my "smart" thermostat, the batch file method is faster and my thermostat does not complain as the reboot happens very quickly. Since implementing this (9 months ago) I have only had to physically power off and on the access point once. My reboots happen every Monday, Wednesday, and Saturday at 4am.

BSA Red Dot RD3022SB Gummy Sticky problem

Recently I happened across my BSA Red Dot  RD3022SB site which I had not used in many years. It was stuck in a drawer in my work room. I went to pick it up and it was horribly sticky. It seems it was coated with some kind of non slip compound that for unknown reasons had turned gooey.

Using my googlefu I found many forums with people reporting the same issue. most of them just got rid of the site saying it was impossible to clean. Other people reported it could be cleaned with alcohol but that was very laborious. Many people reported that Acetone did not work.

Here is what I did to clean mine.

You will need:
Real Acetone (your wife or girlfriends fingernail polish remove is NOT acetone).
Denatured Alcohol.
Thick Nitrile or Rubber gloves (5 mil or thicker).
rough paper towels.
q-tips.
a respirator or work outside.
Patience.

Put on the gloves and respirator (acetone is not good to breath or have on your skin).
If you have the lens caps put those on so you don't get acetone on the lenses.
Pour a liberal amount of acetone on a folded up paper towel and begin soaking and scrubbing the goo off. It will take several passes to remove it. You will know the gunk is removed when you see the greenish black anodizing under it. I was able to go over all the surfaces and no paint or anything was removed that I did not want removed.

Now go over all the cracks and crevices with q-tips until no more black stuff comes off on to the q-tips.

Remove the lens caps and using q-tips carefully clean around the area that was covered by the lens caps and around the lenses (avoiding contact with the lenses).

Next put the lens caps back on and drench everything with the alcohol and wipe that off. clean the lenses with soap and water. You are done.

The Worst Car Radio/Stereo in the World

I have a 1989 Chevrolet c2500 that someone took out the original stereo and head unit and replaced it with (what I would describe as) the worst radio I have ever used.

The radio was a Pioneer DEH P400UB I hate this thing with the hate of a thousand suns. Attempting to do anything with it while driving results in nearly wrecking the truck.

Replacing the OEM unit appears to be more trouble than it would be worth.

After lots and lots of searching I finally found a good simple to use stereo.

I got a used stereo from a 1998 Subaru Legacy. It was one of the few stereos I could find that also had lots of information online. 20 watts per channel, 4 channels, cassette tape, lcd display and simple easy to use controls.

The unit looks brand new inside and out, mounted it this morning and was able to drive around manipulate the controls with out hardly looking at it and never once came close to wrecking as with the Pioneer.

Also sound real good not quite as sensitive as the one in my 2015 forester. Made by Panasonic.

I have a cassette tape that can connect to an external device, a cassette that can do bluetooth, and a cassette that can play mp3's.

I took the Pioneer radio and put it on my bench to mess with it. Even sitting on my bench where I can give it my full attention I cannot control it easily. It has a single knob that is also a joy stick and a button. It has a remote control but that still does not make it easier.

It works like this when in tuner mode:
the knob is rotated for volume
you move the knob left and right to tune a station
moving the knob up and down selects presets.
the problem is when you try to do this while driving you have to remember what does what and the slightest wrong movement will result in changing the station or moving it off frequency.

Then there is the problem of mistakenly enabling demo mode. if that happens the radio can't be turned off and you have to consult the manual to do that but the manual skips steps and is badly written.

then the other buttons on the radio have multiple functions which change depending on what you are doing. The Pioneer DEH P400UB is a $200 driving hazard distraction radio from hell. Though it does sound good it does not belong in a car.

Don't get me started on the trouble it is just to change balance, fader, and tone controls.

Makita to Skil/Bosch Battery Adapter build

I had a bunch of Skill cordless tools but no battery for them, instead of buying batteries and a charger I found a way to make an adapter to connect my Makita battery to these tools


There are USB adapters for other manufacturers that you could do this with.
Milwaukee
Dewalt
Ridgid
You could make many combinations of adapters.

Clarion RF-484I Connector Pinout

I recently acquired a Clarion RF-484I (FCC ID AX292ARF484I) made for a mid 1980's Subaru (not sure which one). This is a single speaker mono radio (no stereo). The wiring diagram pinout is below. Mine had a connector that had a Blue wire for +12v, Yellow Speaker wire, white and black wires that are bridged and then go to case or common ground, and then 2 wires Red with green stripe, and Red with Blue stripe, for the dial light, it does not really matter which wire is positive or negative since they are independent of case ground or any internal circuitry in the radio. Speaker ground can be to the white wire, or to chassis ground anywhere in the car. There is a small screw on the front of the radio near the AM FM words that is used to tune the antenna for AM reception, mine did not seem to do anything. The way you use it is tune a weak AM station (or your favorite) and turn the screw till it sounds better.

The unit seems to use a max of 200ma at 13.8 volts DC without the dial light. Sound quality is fine for a mono radio, it has Volume, Tone, and push button tuning. To set the buttons. tune a station, pick a button, pull it out, then push it all the way in. Unknown if buttons can be programmed for both AM and FM (probably not). Push the volume knob in to turn on and off.
