I know the blooper feeling. It took a couple of hours to film a 15 minute Resolume Arena demo video for a college assessment. Thanks for your video. I’m all inspired.
@markusfuller Why not a two 240 ohm resistors? This would make the total resistance 120 ohms. With 270 ohm resistors the resistance is now 135 ohm. The extra resistance is going to have more voltage drop across the resistor meaning, a lower voltage from the data signal. The lower voltage on the data signal could be with longer runs not work because now the anode and cathode do not have enough voltage to meet the minimum threshold voltage. This ultimately will make the system think you have more wire length for the DMX Cables. Just so you can understand my background. I have a Bachelors of Science in Electrical Engineering.
Hi, I guess it depends on the tolerance. If it is 20% the real value of a 270 ohm resistor could be 216 ohms. ??? By the way I only have 220 ohms resistors, but their real value are around 216, so if I sold two in parallel, I would have 108 ohm. Do you think it would be enough?
Took a couple of screen shots and will hit the electronics shop on Monday to start gathering the components. Then I'll burn my fingers! Thanks for a great and truly USEFUL video.
Thank Jakob, I was on the verge of taking apart the LED light as it kept on randomly changing colour when I was operating the scanner lights. then I realised it just required a terminator to fix the signal. I hope all is well PS i'm enjoying your videos :-)
A terminator that lights up! ...Brilliant! :) Thanks so much for doing this one. You're starting to amass as many LED fixtures, and toys as are in my studio. By the way, using ordinary XLR cables on too many runs will also lead to errant signals. So, for more than just s few fixtures, yo must use actual shielded DMX cables, as well as the terminators. I really enjoyed this video.
ThomasGrillo > Hi Thomas I think there are 3 actual screened DMX cables there but until I acquire some more I will have to make do with a few microphone cables.
Modular Moog!!! a real one! Mine is software!! - it's great but it's not like the real thing. Thanks for the info on the tester, I'm at the pulling out hair stage with my rig and this will be a useful thing to have.
Can you recommend any wireless dmx control packages ? Currently using a hardware controller to control lasers, smoke, strobe etc. Need the ability to relocate whilst running the lights cheers
Dmx lights are daisy-chained (the output of the first light goes into the input of the second, and so on...) so the termitator only goes on the output of the last light.
You have a fantastic place Markus. Proper furniture ;) As for the termination thing, it happens with quit ea lot of things not just DMX stuff, most serial comms need nulling. I have a few Tascam DA-38 and 88's they need terminating too or you get funky sync issues or they simply ignore each other on a whim, fun times. I believe there was a commercial version of what you made here (?) It was a long time ago though and employed a dual colour red/green led (yes I watched the whole vid lol). Loving the use of the spool as a stand for the XLR style plugs, totally going to use that idea, fab. Do you have a paypal.me? I can't do Patreon, money isn't a regular thing. I just wondered if there was a way I could send literally a few bob your way when I have a lil bit to spare.
Hi Neffers, I was almost going to open the LED light as it kept on randomly changing colour when I was operating the scanner lights. then I realised it just required a terminator to fix the signal. Its fine if you only have a couple of lights but once you start adding more then the Terminator is a must. I could not believe the thousands of LEDs I have here and not one of them was a Bi-Colour LED.
Hi that video was about 4 years ago and Im not sure why i used 270ohms. I think using that 2 led setup meant i wanted 120 per led and theres no 240ohm resistors so i used 270. maybe It was for some reason like that.
well the shows are only 40s 50s 60s music and mainly for the local retirement homes, completely different to the electronic music I like to make myself.
Hello sir thank you for this awesome video. Please i have some cub blinder lights here, they were working well then all just went off. But when I put it on slave or auto mode, it comes on and works well but once I turn it to DMX it goes off and does not comes on Sir. Please sir could you help me too with this please 🙏🙏
Hi I have the Kenton pro solo connected to it so I can use a regular midi keyboard. but the proper one connects into the back and then the Moog CP-2 module becomes useful.
Like the outakes 😊 your like me.. Think with your brain not your mouth.. Ha ha.. Termination is important on any data bus.. RS232 is what DMX or midi is in reality .. Great video as usual..
LOL UA-cam does not pay me enough to own one of these. this was bought by me having to reluctantly sell almost all my old analog gear and use years of savings. the house is almost bare again.
On the schematic, you use 270 ohms resistors for both termination and LED but you keep talking about "soldering the 120 ohm resistor". Unfortunately, I couldn’t make out which you actually used.
Hello Moonbase59 I use the 120ohm for a basic termination of a dmx signal with no leds but i use 270 ohm if i am going to make the circuit with the leds.

I wished you had been my electronics teacher at school. Brilliant as always.
Thank you very much Leigh.
Thanks for the new video Markus, quite enjoyed the outtakes bit. Keep them coming!!!

Brilliant thanks for the video, just ordered everything I need looking forward to this little project
I have to try making one myself, love fiddly stuff when it comes to soldering. Btw, thank you for sharing outtakes, top job!

Nice project mate!
You've got modular synth! Me Envy!!!
I love your videos Markus, but I must say, this time the Modular system was the most interesting for me. :)
Another great video Markus. I noticed that you used that nice wooden cabinet to store all your spare patch leads, sliders and knobs. Oh.. wait... :)
Thanks Eddy. its my old telephone exchange but it must be faulty as it just makes strange noises.
Modular Moog!!! a real one! Mine is software!! - it's great but it's not like the real thing.
Thanks for the info on the tester, I'm at the pulling out hair stage with my rig and this will be a useful thing to have.
dat synth : 0 !!!
Good old BluTac holding us together since 1973.
How do you decide when you need your lead extracting fan?
Can you recommend any wireless dmx control packages ? Currently using a hardware controller to control lasers, smoke, strobe etc. Need the ability to relocate whilst running the lights cheers
You need to give us a full cover on that modular synth !!!
Hi I have only had it a few weeks but eventually I hope to make some video's on it.
+1000
be careful, don't burn those hardworking hands.
is it have to add the terminator(120ohm) for each DMX plug to make it works ?
Dmx lights are daisy-chained (the output of the first light goes into the input of the second, and so on...) so the termitator only goes on the output of the last light.
If I have a 3 pin bicolor LED, how the circuit diagram would be? I only have 1 common chatode
open one of the moog modules up and lets look inside! ;)

What lighting program do you use?
Hello Its the free ipad app from ADJ its called AirstreamDMX but it only works with the Airstream DMX controller
does the wattage matter? Also wasn't it 120 ohms ? WHy did you use 270 ohm for the 2nd design ? Thanks
Hi that video was about 4 years ago and Im not sure why i used 270ohms. I think using that 2 led setup meant i wanted 120 per led and theres no 240ohm resistors so i used 270. maybe It was for some reason like that.
May I know what apps u use and what do I need to run those using an android phone???
Hi The app was specially made for the dmx device. I think it was called airDMX. I know it exists for ipad so i guess it must be available for android.
Where's the show and what kind of music will you be playing?
well the shows are only 40s 50s 60s music and mainly for the local retirement homes, completely different to the electronic music I like to make myself.

How would you use a bi color led here?
the resistor 270 oh fir the tester, is it 1/4W or 1/2W?
Is that one of the new Moog Modular 55 systems I see? 😄
Yes . I had to sell off a lot of my favourite gear to get this but I think it's well worth it. Just waiting for the keyboard to arrive now.
You can use MIDI-CV converter and use it now.
Hi I have the Kenton pro solo connected to it so I can use a regular midi keyboard. but the proper one connects into the back and then the Moog CP-2 module becomes useful.
markusfuller And besides that, You can use sequencer and have fun without keys.
can the dmx decoder cause the flickering too
the flickering may be my camera set to 50Hz
Like the outakes 😊 your like me.. Think with your brain not your mouth.. Ha ha.. Termination is important on any data bus.. RS232 is what DMX or midi is in reality .. Great video as usual..
RS485 actually.
You have a system 55?!?!!? I didn't realize UA-cam paid so well!!!
LOL UA-cam does not pay me enough to own one of these. this was bought by me having to reluctantly sell almost all my old analog gear and use years of savings. the house is almost bare again.
Well congrats and I hope you post some awesome music you've made using this thing! Make Tomita proud!
I doubt I could ever get near to Tomita's level of expertise. though I do have a project I'm working on at the moment with it.
You did danse macabre which is definitely in that style and sounds fantastic so I'm sure it will sound great!
well fingers crossed, I have the idea but only started a few tracks and at the moment Im not that pleased - thats how music is sometimes.
Casually sitting in front of a Moog Modular...
Terminator ? Ahhh the days of scsi
On the schematic, you use 270 ohms resistors for both termination and LED but you keep talking about "soldering the 120 ohm resistor". Unfortunately, I couldn’t make out which you actually used.
Hello Moonbase59 I use the 120ohm for a basic termination of a dmx signal with no leds but i use 270 ohm if i am going to make the circuit with the leds.
@@markusfuller I assumed so, since they’re in parallel. Thanks for the confirmation!
