A guide to building a rollz 5 drum machine

  1. 1. A guide to building arollz-5 drum machine Adapted from the Ciat- Lonbarde website By: Circitfied
  2. 2. introduction• The rollz-5 drum machine is designed by peter blasser.• It is a non-traditional drum machine, in that instead of sequencers it has “pulse Brains”• Pulse brains are transistor-capacitor networks that are patched together to produce repeating complex patterns, with a hint of chaos.• The drum voices are also non-traditional, in that they are more like tone generators with resonators and filters built in. They are built using op-amp circuits.• The basic design consists of 5 pulse modules and 6 drum voices.• The original design can be found at: http://www.ciat-lonbarde.net/rollz5/index.html
  3. 3. Getting started• I suggest you read the original assembly guide: http://www.ciat- lonbarde.net/rollz5/index.html• if you haven’t Built a paper circuit before then it may be worth starting with one of his simpler circuits, this is to show you how much work goes into a fairly simple circuit, before you invest time and money in something this complex. Check out: http://www.ciat- lonbarde.net/paper/index.html
  4. 4. Building time• A 3-node pulse brain takes about 15 minutes to solder and assemble.• 4-node 20 minutes• 5-node 25 minutes• 6-node 30 minutes• Ultrasound filters (2 on each board) 60 minutes• Gongs (2 on each board) 60 minutes• AV-dog, 45 minutes each.You will need to set aside time for wiring up and faultfinding. Wiring up will take about two hours and faultfinding can take a deceptively long time. You also need totake account of the amount of time to populate your toppanel, whether you are using banana jacks or bolts topatch with.
  5. 5. Ordering partsDecide on how many circuits you want to make.Use the bill of materials to formulate how many ofeach component you need.I suggest you order IC holders as well, as this willsave a lot of hassle.It may also be worth thinking about what you aregoing to house the circuits in.Also depending on your budget you need to think howmuch you want to spend on binding posts to connectthe nodes together.You will also need someway of connecting power tothe circuits. Since it all works off of 9V DC, you canjust use a snap on battery connector.
  6. 6. Modifications• All of the drum voices can be tuned.• The tuning is hardwired by using fixed capacitors and resistors.• However, instead you can use potentiometers and rotary switches, to provide more control.• With experience of both methods, I prefer to use fixed settings, it reduces costs and complexities.
  7. 7. Printing the circuit boardsYou will need to print out the files at 200 dpi. However, youmay not have this option so you may have to cut and paste theimage into word and expand it to the right size. I printed acircuit out when I thought it was the correct size and thenused an IC holder to compare the pin configuration size.
  8. 8. Assembling the circuit boardsCut out the circuit board andcrease it along the dashed line. Putthis over a piece of card (cereal boxwill do), then glue it in place. Usesomething sharp to puncturethrough the component holes. It isimportant to keep the paper circuitsquared up, as the components willnot align on the top and bottomsurface.
  9. 9. Populating the circuit boardsWith conventional circuit boards, you populated the circuit board with thesmallest components first.However, I find that it is best to populate the boards with the components thathave the longest legs. This enables a framework to be assembled relatively fast.Push the components through the holes and bend the legs along the circuittraces. The component legs form the traces on the circuit board.Solder together any legs that overlap. Instead of cutting the legs short, bendthem so that they can reach another component along the trace. This will createa much stronger circuit board.any resistors laBelled ‘0’ are jumper wires.Use wire to bridge big gaps in the circuit.I always use long wires for the power and any other connections, this gives youflexibility during assembly.
  10. 10. Half assembled circuit boards
  11. 11. Assemble circuits until you feel suicidal
  12. 12. Populate top panelI was luckyenough toacquire thesepopulatedpanels. I drilledout the panels,to provideindividual audiooutputs for eachdrum voice. I alsodrilled out holesfor LED powerindicator, powerjack and masteroutput. I usedthe central knobas a volumecontroller.
  13. 13. As can be seen, I hadto assemble a fewextra pulse brainsto account for theextra connectors.
  14. 14. To wire up individual audio outputs I used break circuit audiosockets, this meant that the audio for each drum voice wouldautomatically be routed through to the master unless a jack wasplugged into that drum voice. All of the drum voices that connectto the master output are in this drum machine soldered togetheronto the middle leg of a potentiometer. With the other two legsgetting wired to either ground or the master output jack.
  15. 15. TestingTurn it on and prayit works!I plugged a speakerinto one individualoutput and thenwired some nodes toit. Testing eachdrum voiceindividually.if a voice isn’tworking, check forbreaks in thecircuit. If it stilldoesn’t work thencheck componentvalues. Then if allelse fails tryswapping out an IC.
  16. 16. Your nearly ready to playSo now you havetested all yourcircuit boards. Iwould suggest thatyou now insulate allyour circuitboards. I usedmasking tape. All itis, is to stop thebare traces fromtouching eachother.
