My first ever arduino thing.simply understood and fairly jargon free .drawing showing the theory of the wiring, code basics explained as best i can
mode 1 is 33variable multitone noise machine ,full on mayhem.
mode 2 is code based 24step tone sequencer with bonus random functions.
mode 3 is electro mechanical 4 step multitonal noise sequencer.,(6switches2knobs per step!)speed+sustain ,

, .using arduino mega 2560 and a motor driven rotary switcher, iv added a power amp+speakers in the box.

wanted to go impressive as i got the posh mega board.but couldn't really spend money.i spent a couple of days getting the basics, like  simple code writing and ordering a relay shield ,which has not arrived yet .but i didn't need it anyway.then a couple more days making this.using with parts i had lying around the studio/workshop.a few more days adding to the recipie, then a week writing what i did for you.then more adding and trying to get these instructions into a workable order,mentioning later adjustments on the relavent step.

higher quality video, demonstrating the 3 modes

vid of it stepping.

these were done during development.

Latest update iv got it sequencing analog sounding noises,it goes all step by step one sound at a time if you use timeing devices in the code ,delay,while,clock,milliseconds, so iv added a rotary switch and motor to get it to step while making 6 noises at once using seven parameters per step  
  . iv added step lights ,
using pmw messes up the sound,using a analog input as a input made it crash,I also tried using the rotor values to trigger LEDs but the debounce was awful ,using code devices to fix this means timers or lumpy code, , iv found can use the digital inputs from the rotor switch to drive the lights big resistor and diode permitting.

, anyway I'm really happy with the result ,

it can all runs on a 12 volt adapter.has a internal amplifyer with cooling fan.
with usb power only it has a small speaker for reference. Iv also made it possible to power it with up to 16 volts to get as much sound out the amp as possible.

becides having 24 switches , 8 nobs and a slider to play with, it has a line out, mode switch,step speed nob, rotor and light power save switch.preamp volume control.amp volume control, amp fan speed.

edit after looking for hints online about sequencer code it appears that everybody is using beavises code , i want to understand what im doing so i wrote my own fresh code.

Any questions or aspects of these instructions your having difficulty with,asking doesn't hurt,I want this guide to work and I like to hear what you think, thanks for looking , I hope you enjoy , the first few steps 234&5 are basic soldering and construction advice 

Step 1: Stuff I Used Making This

ok so most  all of this stuff i had laying about the place, heres a breakdown of it with estimates of what they may cost, imagination will save you a bunch of cash.


, connector pins out the back of some broken cd drives (the bin) removed and attached to stripboard  (maplin) illistrated,or you could buy a proto shield , i think £10 to£15
arduino mega £40(maplin) .
10kohm resistors(multipak qty 1000 various values maplin),£7.99.
switches (bulk buy from ebay china£10 for 100 ),
pots ( value pack maplin),£5
rainbow wire (cpc, farnell)£15 for 100m i think
, heatshrink (cpc, farnell). x4 shrink rate 5mm down to 2mm £2 per meter
tiny 8ohm speaker (came with squair wave generator middlesex uni tech resources),£5. or just the speaker probably costs £2
2 car speakers 4 inch 4ohm 20w 40w max(out of my suzuki swift),
power socket(maplin)£2,
phono socket (ebay).£5 for 10
a computer to do the programming(win7 64, hp)£600 something
.(and an amplifier* (kemo germany) for loud sound)i think it was about£20
colour cycling leds3mm (4), ebay about£10 for 100
strip-board,£5 to £10
diodes (not sure of the value 3mm dia x 5mm)
rotary switch things(they came in a maplin value switch assortment bag)£5
a 12v motor with attached gears to slow it down(mine was salvaged from a printer) mfa como drill do some excellent motors for this job.for between £15 and£40
dowel or some other easily workable stick shaped material 6 mm diameter. i used the graphite cores out of some aa batterys.
i later added a laptop style power supply16v,this ment i also had to use a power regulator transistor 6v(ts7806cz)£1.50 maplin
i also added a 16v capacitor 1500uf over the rotor motor contacts, it came off an old pc motherboard.

material to make a case,
studding m4 ,£4 to £7 per meter depending if galvanized or stainless. B7Q do it but cpc is cheaper.
brass pipe,£8 per m from diy superstore b&q
perspex (found material reject from a factory)(been sitting under my waste paper bin for years, i feel this has been a good use for it), you can use any material you like ,(metallic needs insulating) , tupperware works well.
plywood to mount speaker...screws im using self drilling non split type £7 for 100 .25mm, 
rapid set 5mins epoxy glue.£5 a tube
zippy cable ties 4" for wire tidiness, £8/1000
*amplifier(i made this ages ago and its been sitting in a box on a shelf.)
a 40w homemade amplifyer based on a similar product illistrated.£20?
tobacco tin(golden Virginia limited edition) or some sheet material to mount it onto.ponudland is good for these sort of things.
heat sync and fan (bin computer salvage)£20 ish
, 2 pots (maplin potentiometer value bag £5),
phono socket £1.99, .choc blocks £1(Cobb electrical northumberland heath +441322334592).
iron, wire cutter stripper, solder removal pump.step drill on drill, pliers . forceps.mole grips. dremmel, angle grinder. jigsaw for making case.or a holessaw if you prefer. hot glue gun, spatula. bolt cutters, files , sandpaper.lighter for heatshrink. multimeter.drill bit same size as your leds. rule. marker pens.
wow thanks, 19k views and no questions, <br> i cant be that good. <br>i dont bite.. much!, <br>
Right about at &quot;electro mechanical 4 step multitonal noise sequencer&quot; is where the build details went whizzing past my head. I watched the video and like the finished version. It seems like I've heard a song like that before. You should see if Stereolab wants to buy one of these, or maybe Art of Noise. Cool project.
thanks , im still tweeking bits, iv put a better video up now, demonstrating the modes,
4those of ya that like diagrams ,I'm drawing a full circuit diagram, with a pen. <br>Stay tuned, <br>Thanks for looking
