Many years ago i started segmenting my network using vlans.
In 2022 i started to reconfigure my lab and using a lot more Mikrotik switches. So how many … is to many, because i always overdo stuff.
Well .. is 9 to many for home environments?
default vlan – did’t bother to configure
old DMZ .. to be migrated
DMZ – my servers live here
Wifi personal workstations – Mobiles and laptops .. macaddress limited
IOT – only arduino’s, raspberries and other hardware live here
Personal workstations – UTP connected workstations with less networking limitations
LAB – My lab environment, Ovirt virtualisation for fun and manage access to servers in dmz
Storage – my SFP enabled all-flash storage
Management – really tight restricted access to management interfaces (switches/routers/storage/ILO)
Hard to manage? All those vlan’s? .. Sure, but i learn a lot! (Not really .. when you got the basics down, more of the same. Hardest part? .. not cutting-off connections/switchports you are using!)
Got a working amiga again. \o/ woot Needed to replace Paula chip, cleaning and some TLC.
Modulator
Chip donor
Scart cable i’ve got is one without the resistors, so my monitor isn’t detecting the signal. Using a A520 modulator works. At least RF, don’t know why RCA/composite video isn’t working.
Even a memory expansion and second drive (5.24 inch) are working.
One of the first disks i tested
To do:
Fix something to get disk images from and to my pc.
(My old catweasel card only fits in a ISA slot which i don’t have any more)
I was wrong .. i’ve got a IV Catweasel .. PCI it is
Fix scart
Fix my Action Replay, which i soldered into a non working state apparently .. 🙂
Get a better mouse!

Disks to convert:
Personal text files from ages ago
My first seka demo
My oscillator drawing program
Other assembly source files
Got another one running today also:

ALTAIR 8800 EMULATOR KIT
The Altair 8800 is a microcomputer designed in 1974 and based on the intel 8080 CPU. Using only switches to program and leds for output. Even my DIY build computer has a hex keyboard input and 7segments display.
Omnicharge 20+ Usb C Wireless Power Bank 20,000mAh Power Delivery 3.0 + Quick Charge 3.0
You can use this as a mobile soldering station using a TS100 soldering iron.
Rigol Oscilloscope DS1054

Got this one now, superb. Will post about this
Tv Stick Dab Fm Dvb-t RTL2832 R820T Sdr RTL-SDR Dongle Stick Digitale Tv Tuner Ontvanger TVSDVBS816
Modded this one, as part of my modular amiga system where i wanted to remake every part onto 10×15 euro prints. So i could swap things out for other boards.
Memory expansion
512k .. missing in action Go a new one in … ?
Boot selector
Swaps df0 and df1 DIY version was a wirewrap ic socket with a cross switch, now i have a Gotek buffered switching module with can be actvated with a keystroke. (Gotek post)
Keyboard mod
Hidden key (in the space of the stands, which triggered a extra key stroke)
Kickstart selector
A print you can insert in the ROM socket of your amiga. Had only 1.2 and 1.3. Now there are many .. like diagnostic roms. I made a altered 1.2 version .. which was unusable .. i f*cked it up
SID mod
Added a sid parallel on the 8020 CIA chip
Gotek driver emulator
I made a arduino version to read disks. (Other post) But this is a disk image drive emulator. See Gotek post
Boot sector warn
Piezo beeper which warned me when a boot sector was being written (virus alert)
Sound filter fix
Amiga audio filter enhancer, using capacitors and resistors
A fancy keyboard….. At last a clickety keyboard. A Razer Blackwidow V3 mechanical keyboard. I’m not a gamer, but i like the clickety sounds. RGB leds are always nice to play with.
One of the nice things about razer is the Linux support!
Put the box flat on the table to switch off. When you put it on one side, it will controll your lights brightness. 20,40,60,80 and 100%, just by rotating and putting it down on its sides.

Nice to have’s : Arduino-sleep mode, wakeup with a movement sensor.
