The fluxengine works perfectly!
Copied the files used in this post:
https://www.henriaanstoot.nl/2022/11/16/assembly-in-dosbox-and-draw-a-line/
using fluxengine on linux to a 720kb floppy.
And OBS to capture the video (using a VGA to HDMI convertor and the Camlink)
I’ve build a drawbridge disk reader in the past:
https://www.henriaanstoot.nl/2022/04/26/started-to-build-a-drawbridge/
I found an even more interesting project.
I was looking for a solution to my XT laser problem.
https://www.henriaanstoot.nl/2022/11/25/disk-troubles-or-missing-old-skool-hardware/
And found this! The fluxengine
https://github.com/davidgiven/fluxengine
An open source project using a small controller board.
“Flashing” some software on the board and soldering a pinheader was easy.
When connecting a flat cable and a floppy drive, you end up with a device which can read many formats. Including dos 1.44/720 and amiga.
Nice package it came in
Reading and writing a MSDOS disk, no problem.
Imaging an amiga disk .. easy!
You need to compile some software, but it was well documented
For a while i’ve been using the wireless shelly button for all kinds of notifications.
Most of the time i like to use it as a kind of alarm/need-help-now button.
The f*ckin’ awesome button i’m talking about (pictured above) is a small (45x45mm 16mm height) button, which can connect to your wifi and send MQTT messages.
It even has a strap thingy to attach it to your keychain,
Four types of messages:
When using pushover, you can push alarm and messages to your android (even overriding mute/silent if you configure it that way!)
Configuring the button:

Weird title i know.
I have several ip cameras which monitor movement in and around our home.
I’m using Zoneminder and other home automation systems but i want to scan through a bunch of files uploaded by the security cameras to my secondary fileserver.
So what is interesting?
| 76 % | 1438 | SDAlarm_20221129-213515.jpg | 3145 | .......-.......................X..................................................................... | 76 % | 1439 | SDAlarm_20221129-213517.jpg | 3661 | ..............-.....................X................................................................ | 76 % | 1440 | SDAlarm_20221129-213519.jpg | 3739 | ...........-.........................X............................................................... | 77 % | 1441 | SDAlarm_20221129-213521.jpg | 3704 | .....-...............................X...............................................................
Looking at the output we see:
At 76% of the captured images (image 1438) the threshold was above 3000 and the minus gives us the information of the difference between this image and the previous, the X marks the difference between current image and the baseline.
| percent | image number | filename | difference | graphbar
Bash script:
#!/bin/bash
threshold=3000
baseline=$( ls SDAlarm*jpg | head -1)
previous=$( ls SDAlarm*jpg | head -1)
total=$( ls *.jpg |wc -l)
echo "Number of files : $total"
nr=1
ls *jpg | while read; do
graph="....................................................................................................."
diff=$(compare -verbose -metric MAE $baseline $REPLY /dev/null 2>&1 | grep all | awk '{ print $2 }' | cut -f1 -d. )
prevdiff=$(compare -verbose -metric MAE $previous $REPLY /dev/null 2>&1 | grep all | awk '{ print $2 }' | cut -f1 -d. )
line=$( echo "100 / $total * $nr" | bc -l | cut -f1 -d.)
line=$(( $line + 1))
#echo -n "$line | $nr | $REPLY | "
#echo $diff
draw1=$(( $diff / 100 + 1))
draw2=$(( $prevdiff / 100 + 1))
graph=$(echo $graph | sed "s/./X/$draw1")
graph=$(echo $graph | sed "s/./-/$draw2")
if [ $diff -gt $threshold ] ; then
printf "| %4s %% | %3s | %30s | %5s | %102s \n" $line $nr $REPLY $diff $graph
fi
nr=$(( $nr +1 ))
previous=$REPLY
done
Want to see only difference with previous image?
change:
if [ $diff -gt $threshold ] ; then
into
if [ $prevdiff -gt $threshold ] ; then
We take a lot of pictures, with our Nikon camera and our mobile phones.
(Apparently in 2019 5544 pictures)
Some stats

Besides android pictures being automatically uploaded to our nextcloud, I’m using some apps and scripts to get pictures and movies stored on my fileserver. (bash scripts/andftp)
For sorting those media files, i made a sorting script.
(Today I added a location sorting addition using GPS information stored in the exif information.
INSTALLING
pip3 install reverse_geocoder
You need python3, exiftool, exiftime and mediainfo
copy below python script in ~/bin/reverse2.py
( need more info? change last print entry admin1/admin2)
[{‘lat’: ‘-39.45556’, ‘lon’: ‘173.85833’, ‘name’: ‘Opunake’, ‘admin1’: ‘Taranaki’, ‘admin2’: ‘South Taranaki District’, ‘cc’: ‘NZ’}]

lat=sys.argv[1]
lon=sys.argv[2]
coordinates = (lat,lon)
results = rg.search(coordinates) # default mode = 2
#print (results)
for entry in results:
print(entry['name'] + "(" + entry['cc'] + ")")
And a bash script /usr/local/bin/exifsort.sh

I bought a XT Laser/3 a while ago.
And i wanted to get my old programs running on it again.
One of the disk i found was a 5.25 inch boot disk which should contain a boot demo i’ve made in the past with Edk.
But it is the secondary drive in this system. Those old machines lack a bios you can change.
And change A: for B: for example.
Some machines had a program which could alter boot settings. (not this one)
So i was playing with jumpers and dipswitches on the motherboard.
( Drive select / Termination / drive before or after the twist in the flatcable. )
Wellll leave the boot order for now, i needed to get software on the machine using floppy’s.
I could not find empty HD disks (1.44MB which i wanted to use)
So i took a DD disk and a drill ..
I bought an external usb floppy drive.
Now i have everything to get my programs on the msdos machine.
EXCEPT ….
Diskette didn’t work in the drives.
So i bought new old stock diskettes online.
Now i have everything
WRONG again
Formatted 1.44 disk in USBfloppy drive .. OK
Read in 3.5 drive on the MSDOS machine .. NOT OK
Check drive in MSDOS machine .. is 1.44MB .. OK
… check floppy controller in MSDOS machine .. NOT OKAY
(720kb is 300kbits per second and 1.44 HD 500kbits per second)
So i’m limited to 720kb due to the controller ..
Can the USB Floppy drive read/write 720kb disks .. NO!
( A cheap series made with drives only supporting HD disks )
Alternatives? .. Serial maybe, there is Norton Commander on the MSDOS machine so i could use “link”
Do i still have a USB-RS232 sub-d cable ? YES!
Nullmodem cable? NO
Make a null modem cable .. i’ve made those before .. BUT no sub-d connectors.
I’ve been throwing away too much in the past.
Now i have to buy those things again:
VGA – 8bit ISA – have 2 now
Floppy drive – have one for 1.44
8bit soundblaster compatible – TODO
Nullmodem – well i’ve bought connectors for those
2023-01-11 Updated the script! More functions
I’m using below scripts to generate tunebooks.
These books I can print OR view on a tablet using my DIY bluetooth page turner. ( see other post )
I often work on tunes, add notes, text or write other versions.
So i needed a fast and simple way to re-generate a tunebook. ( hence the date on the title page and in the name, so i know whats the most recent version )
Now i have a separate tunebook for each instrument, with the same looks
What does this script?

After 3 times being cancelled due to Covid, it finally happened.
We got to get to the “Evening of the film music”
We held on to our tickets, as apparently 90% of the people!
We love film music, but it is a treat when there is a live orchestra.
(And special effects .. like a stuntman hanging from the roof, fire (not like Rammstein haha), and big displays)
If you get the chance .. go!
Wicked good musicians and singers.
Tania Kross was amazing!
Previous concerts we went to: Jeff Wayne’s War of the Worlds. The star wars suite, and an evening with Hans ZImmer.
Intermission
UPDATE 20240122 : below
I’ve got my RFXCOM connected to my Domoticz, and not connected to my HA.
To have the changes of my IOT devices being known to HomeAssistant I wanted to use mqtt.
Domoticz writes the mqtt topic (payload) like this
(topic: domoticz/out)
{
"Battery" : 100,
"LastUpdate" : "2022-11-17 18:21:59",
"RSSI" : 6,
"description" : "",
"dtype" : "Temp + Humidity",
"hwid" : "4",
"id" : "230E",
"idx" : 8461,
"name" : "Living Temp/Hum",
"nvalue" : 0,
"stype" : "Cresta, TFA TS34C",
"svalue1" : "20.0",
"svalue2" : "60",
"svalue3" : "1",
"unit" : 1
}
So you can’t see which device it is by the topic name, the idx is in the json (8461)
To get this device ( a temperature sensor) into HA using mqtt i rewrote the mqtt topic using NodeRed
NodeRed flow
[

The function node code ( rewrites the mqtt topic)
var varidx = msg.payload.idx; msg.topic = "home/"+varidx+"/payload"; return msg;
Now we have a idx separated payload “home/IDX/payload”
(The other entries svalue/nvalue are from testing.
Adding the MQTT entries to HomeAssistant configuration.conf
mqtt:
sensor:
- name: "LivingTemperature"
state_topic: "home/8461/payload"
unit_of_measurement: "°C"
value_template: "{{ value_json.svalue1 }}"
- name: "LivingHumidity"
state_topic: "home/8461/payload"
unit_of_measurement: "%"
value_template: "{{ value_json.svalue2 }}"
Now i can add the card to the dashboard.
This should now be a generic mqtt translator
A quick update:
Adding a motion sensor:
Home Assistant
- name: "LivingMotion"
state_topic: "home/45/payload"
value_template: "{{ value_json.nvalue }}"
Add sensors to be reset to the switch node

UPDATE 20240122
I’m using domoticz as a 433->mqtt bridge, and some virtual devices i can toggle with curl (bash scripts)
I needed to make a custom 433 door sensor in Home Assistant with toggles to OFF after a few seconds. (There is NO off signal in this cheap sensor i’m using)
I’m changing the payload complete, to have a payload which matches the device class for door: (state with on/off)
It was nvalue = 0/1
(Whenever the IDX changes, I only have to update this Nodered part)
HA won’t notice the change.
var nvalue = msg.payload.nvalue;
msg.payload = {};
if(nvalue == 1)
{
msg.payload.state = "ON";
return msg;
}
AND after 5 seconds
msg.payload = {};
msg.payload.state = "OFF";
return msg;

HA Part : Instead of the generic setup above (Old post part)
mqtt:
binary_sensor:
- name: "FrontDoor"
state_topic: "home/frontdoor/payload"
value_template: "{{ value_json.state }}"
device_class: door
Below my setup in Dosbox.
(As used 30 years ago)
First install dosbox (Linux/Windows)
download the package with used files and compilers from here:
https://media.henriaanstoot.nl/assembly.tgz
extract with tar xzvf /tmp/assembly.tgz to a directory
start dosbox and mount the directory as C
mount c /path/assembly
Run “a line”, this a batchfile which starts the editor (qedit)
When closing the file (esc – q menu)
It will compile the assembly and write out a executable
This is the batchfile
@echo off q %1.asm cls masm %1.asm; link %1.obj; exe2bin %1.exe %1.com echo READY!
