It is based on the same idea of chaining two 12V DC bricks in series to provide bipolar 12V and regulating the +12V rail to provide +5V as necessary. 8 | I disliked the layout of the M15 system and figured I would correct my gripes in this design. It may not be perfect, but if you want perfect, you'd probably be using a linear supply. 9 | These boards can act as bus boards for other supplies. Just connect +/-12V and ground to the proper headers on one of the screw terminals and you're good to go. 10 | 11 | ![Imgur](https://i.imgur.com/J3VkgmR.png) 12 | -------------------------------------------------------------------------------- /Octaverter/Octaverter Rev 5 BOM.pdf: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/MMImodular/Modules/88aa83b7eb0126473968a41e80a9d13bd10409e0/Octaverter/Octaverter Rev 5 BOM.pdf -------------------------------------------------------------------------------- /Octaverter/Octaverter Rev 5 BOM.xlsx: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/MMImodular/Modules/88aa83b7eb0126473968a41e80a9d13bd10409e0/Octaverter/Octaverter Rev 5 BOM.xlsx -------------------------------------------------------------------------------- /Octaverter/Octaverter Rev 5 Panel.brd: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 | 30 | 31 | 32 | 33 | 34 | 35 | 36 | 37 | 38 | 39 | 40 | 41 | 42 | 43 | 44 | 45 | 46 | 47 | 48 | 49 | 50 | 51 | 52 | 53 | 54 | 55 | 56 | 57 | 58 | 59 | 60 | 61 | 62 | 63 | 64 | 65 | 66 | 67 | 68 | 69 | 70 | 71 | 72 | 73 | 74 | 75 | 76 | 77 | 78 | 79 | 80 | 81 | 82 | 83 | 84 | 85 | 86 | 87 | 88 | 89 | 90 | 91 | 92 | 93 | 94 | 95 | 96 | 97 | 98 | 99 | 100 | 101 | 102 | 103 | 104 | 105 | 106 | 107 | 108 | 109 | 110 | 111 | 112 | 113 | 114 | 115 | 116 | 117 | 118 | 119 | 120 | 121 | 122 | 123 | 124 | 125 | 126 | 127 | 128 | 129 | 130 | 131 | 132 | 133 | 134 | 135 | 136 | 137 | 138 | 139 | 140 | 141 | 142 | 143 | 144 | 145 | 146 | 147 | 148 | 149 | 150 | 151 | 152 | 153 | 154 | 155 | 156 | 157 | 158 | 159 | 160 | 161 | 162 | 163 | 164 | 165 | 166 | 167 | 168 | 169 | 170 | 171 | 172 | 173 | 174 | 175 | 176 | 177 | 178 | 179 | 180 | 181 | 182 | 183 | 184 | 185 | 186 | 187 | 188 | 189 | 190 | 191 | 192 | 193 | 194 | 195 | 196 | 197 | 198 | 199 | 200 | 201 | 202 | 203 | 204 | 205 | 206 | 207 | 208 | 209 | 210 | 211 | 212 | 213 | 214 | 215 | 216 | 217 | 218 | 219 | 220 | 221 | 222 | 223 | 224 | 225 | 226 | 227 | 228 | 229 | 230 | 231 | 232 | 233 | 234 | 235 | 236 | 237 | 238 | 239 | 240 | 241 | 242 | 243 | 244 | 245 | 246 | 247 | 248 | 249 | 250 | 251 | 252 | 253 | 254 | 255 | 256 | 257 | 258 | 259 | 260 | 261 | 262 | 263 | 264 | 265 | 266 | 267 | 268 | 269 | 270 | 271 | 272 | 273 | 274 | 275 | 276 | 277 | 278 | 279 | 280 | 281 | 282 | 283 | 284 | 285 | 286 | 287 | 288 | 289 | 290 | 291 | 292 | 293 | 294 | 295 | 296 | 297 | 298 | 299 | 300 | 301 | 302 | 303 | 304 | 305 | 306 | 307 | 308 | 309 | 310 | 311 | 312 | 313 | 314 | 315 | 316 | 317 | 318 | 319 | 320 | 321 | 322 | 323 | 324 | 325 | 326 | 327 | 328 | 329 | 330 | 331 | 332 | 333 | 334 | 335 | 336 | 337 | 338 | 339 | 340 | 341 | 342 | 343 | 344 | 345 | 346 | 347 | 348 | 349 | 350 | 351 | 352 | 353 | 354 | 355 | <b>EAGLE Design Rules</b> 356 | <p> 357 | Die Standard-Design-Rules sind so gewählt, dass sie für 358 | die meisten Anwendungen passen.

The data here is to help beta testers with their builds. Nothing is guaranteed to work just yet.** 4 | 5 | * 8 attenuverters in 12hp 6 | * Each attenuverter is normalled to the one below it if no plug is inserted to its output 7 | * Each input is normalled to 5V if no plug is inserted 8 | * Each attenuverter has a gain of 1.5 9 | * Bi-color LEDs to help visualize the output, red for negative, green for positive 10 | 11 | Octaverter has been in the works for several months and has gone through a record number of revisions. This is 5th and hopefully last version of the module. Octaverter is a one-stop-shop for many functions beyond just attenuversion. It can be used as a mixer, offset generator, sidechain generator, amplifier, and even distortion. 12 | 13 | ![Imgur](https://i.imgur.com/2GcZ4NA.jpg) 14 | 15 | ![Imgur](https://i.imgur.com/RAdBGUk.jpg) 16 | -------------------------------------------------------------------------------- /Passive Attenuator/Quick Fix Mix/Quick Fix Mix.brd: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 | 30 | 31 | 32 | 33 | 34 | 35 | 36 | 37 | 38 | 39 | 40 | 41 | 42 | 43 | 44 | 45 | 46 | 47 | 48 | 49 | 50 | 51 | 52 | 53 | 54 | 55 | 56 | 57 | 58 | 59 | 60 | 61 | 62 | 63 | 64 | 65 | 66 | 67 | 68 | 69 | 70 | 71 | 72 | 73 | 74 | 75 | 76 | 77 | 78 | 79 | 80 | 81 | 82 | 83 | 84 | 85 | 86 | 87 | 88 | 89 | 90 | 91 | 92 | 93 | 94 | 95 | 96 | 97 | 98 | 99 | 100 | 101 | 102 | 103 | 104 | 105 | 106 | 107 | 108 | 109 | 110 | 111 | 112 | 113 | 114 | 115 | 116 | 117 | 118 | 119 | 120 | 121 | 122 | 123 | 124 | 125 | 126 | 127 | 128 | 129 | 130 | 131 | 132 | 133 | 134 | 135 | 136 | 137 | 138 | 139 | 140 | 141 | 142 | 143 | 144 | 145 | 146 | 147 | 148 | 149 | 150 | 151 | 152 | 153 | 154 | 155 | 156 | 157 | 158 | 159 | 160 | 161 | 162 | 163 | 164 | 165 | 166 | 167 | 168 | 169 | 170 | 171 | 172 | 173 | 174 | 175 | 176 | 177 | 178 | 179 | 180 | 181 | I didn't 182 | know so 183 | many 184 | jacks 185 | could 186 | fit in 187 | 4hp 188 | cc-by-sa: 189 | Matt Gaines 190 | May 2018 191 | 192 | 193 | 194 | Generated from <b>uClouds_002.sch</b><p> 195 | by exp-lbrs.ulp 196 | 197 | 198 | 199 | 200 | 201 | 202 | 203 | 204 | 205 | 206 | 207 | 208 | 209 | 210 | 211 | 212 | 213 | >NAME 214 | 215 | 216 | 217 | 218 | 219 | 220 | 221 | 222 | 223 | 224 | 225 | 226 | 227 | 228 | 229 | 230 | 231 | >NAME 232 | 233 | 234 | 235 | 236 | Generated from <b>veils_v40.sch</b><p> 237 | by exp-lbrs.ulp 238 | 239 | 240 | 241 | 242 | 243 | 244 | 245 | 246 | 247 | 248 | 249 | 250 | 251 | 252 | 253 | >NAME 254 | >VALUE 255 | 256 | 257 | 258 | 259 | 260 | 261 | <b>RESISTOR</b><p> 262 | chip 263 | 264 | 265 | 266 | 267 | 268 | 269 | 270 | 271 | >NAME 272 | >VALUE 273 | 274 | 275 | 276 | 277 | 278 | 279 | 280 | 281 | 282 | 283 | 284 | 285 | 286 | 287 | 288 | 289 | <b>EAGLE Design Rules</b> 290 | <p> 291 | Die Standard-Design-Rules sind so gewählt, dass sie für 292 | die meisten Anwendungen passen.

After using a restored Buchla at the Oberlin Conservatory of Music, the 295 became one of my favorite modules in the whole case. Buchla modular is far out of my budget so with the original schematics in hand, I made a much more compact 3U version of it. The circuitry is exactly the same, though more modern op-amps have to be used since the ones used in the original design are no longer available. 13 | 14 | --- 15 | 16 | **Things to note when building** 17 | 18 | It is absolutely imperative that you solder R13, R39, R17, R37, R19, R35, R25, and R33 properly before mounting the trim pots as they will be very difficult to reach once all components are in place. To confirm they are soldered properly, measure the resistance between the two middle pins of each trim pot location. For instance, the resistance between the middle pin of VR10 and VR9 should be roughly 68 kOhms. 19 | 20 | In addition, please heed the warning on the front of the PCB and place the trim pots on the back of the module. There is not enough space between the PCB and panel for the trim pots and having them on the back allows for you to tune everything without taking the panel off. I kept the silk screen for the pots on the top side in order to avoid cluttering the bottom silkscreen layer. 21 | 22 | As for the illuminated slide pots, there's a few things to consider. They are acting as cross faders so any value between 10k and 100k should work just fine. They are taking an audio signal so ideally you want audio response, but linear response will function just fine. Ideal shaft length is 15mm but I have used 10mm successfully, the tops are just a tad close to the panel. You do not want a center detent if you can help it. The sliders I used can be found on Mouser: 652-PTL20-10R0-103B2 23 | 24 | --- 25 | 26 | **How to tune your 295** 27 | 28 | Note: You may want to keep the volume down for this or else you might give yourself a headache. 29 | 30 | *Tuning Frequency* 31 | 32 | * Turn each 20k trim pot so that every band has maximum gain (some bands will self-oscillate, others will not) 33 | * Patch white noise to **IN** and monitor **SUM** with a FFT-capable spectrum analyzer or parametric/graphic EQ 34 | * Slide the potentiometer of the band you want to tune all the way to the right 35 | * Turn the appropriate 100k trim pot until the peak is centered on the desired frequency 36 | * Repeat for each band 37 | 38 | *Tuning Gain/Q* 39 | 40 | * Using a sine wave oscillator, patch the wave directly to your output 41 | * Set the gain between your modular and a VU meter (usually within a DAW) so that the output is now at 0dB 42 | * Leaving the output gain unchanged, move the sine wave to an attenuator and attenuate it down to -6.5dB 43 | * Patch this attenuated sine wave to **IN** then patch **SUM** to your output 44 | * Slide the potentiometer of the band you want to tune all the way to the right 45 | * Tune your sine wave to match the frequency of the band you would like to tune 46 | * Turn the appropriate 20k trim pot until your output is at 0dB 47 | * Repeat for each band 48 | 49 | It may help to monitor your output with an oscilloscope to see how your output clips. Note that each band clips asymmetrically. This can cause some interesting harmonics to show up so feel free to tune your filter to taste, no need to follow this guide to a T. 50 | 51 | --- 52 | 53 | PCB and panel designed by me 54 | 55 | Original schematic by Don Buchla 56 | 57 | ![Imgur](https://i.imgur.com/43DXM32.jpg) 58 | 59 | ![Imgur](https://i.imgur.com/BFru6uz.jpg) 60 | -------------------------------------------------------------------------------- /Two Nine Five/Top Placement Diagram.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/MMImodular/Modules/88aa83b7eb0126473968a41e80a9d13bd10409e0/Two Nine Five/Top Placement Diagram.png -------------------------------------------------------------------------------- /Two Nine Five/Two Nine Five Rev 1 BOM.pdf: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/MMImodular/Modules/88aa83b7eb0126473968a41e80a9d13bd10409e0/Two Nine Five/Two Nine Five Rev 1 BOM.pdf -------------------------------------------------------------------------------- /Two Nine Five/Two Nine Five Rev 1 BOM.xlsx: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/MMImodular/Modules/88aa83b7eb0126473968a41e80a9d13bd10409e0/Two Nine Five/Two Nine Five Rev 1 BOM.xlsx -------------------------------------------------------------------------------- /Two Nine Five/Two Nine Five Schematic.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/MMImodular/Modules/88aa83b7eb0126473968a41e80a9d13bd10409e0/Two Nine Five/Two Nine Five Schematic.png -------------------------------------------------------------------------------- /USBPower/README.md: -------------------------------------------------------------------------------- 1 | # USB Power 2 | 3 | * Based on Tom Whitwell's StupidUSBPower 4 | * Integrated better DC-DC converter and removed frivolous features 5 | * Rated to 416mA, capable of 110 ~ 140% overload with automatic recovery once fault condition is removed 6 | 7 | This power supply is a low cost and low profile way to power a small lunchbox eurorack system. It is also a useful power supply for testing newly built modules outside of a larger system, especially if you must commute to your workspace. 8 | 9 | ___ 10 | 11 | The Meanwell DC-DC converter used in this power supply has a few important specifications to consider. 12 | * Under full load, the DC-DC converter will draw upwards of 2300mA direct from your USB power brick. Make sure it can supply ~3A if you plan on running your PSU near the max current spec. 13 | * Maximum load capacitance is 440uF per output. Approaching this may cause instability upon power-up. This needs more investigation on my part so I will update this list if I figure out more specific cases of instability. 14 | * There is an under-voltage lockout implemented in this converter. It takes 4.4V to start the converter and it will shut down if it goes below 4.2V. This important because some users have experienced instability with USB cables that are incapable of supplying power. Voltage drop across the cable may be enough to go below 4.2V and result in a boot loop. 15 | 16 | ___ 17 | **Known module incompatibilities** 18 | 19 | These are modules that people have plugged in and run in to boot looping issues with, despite the PSU operating normally otherwise.
