- Page 1 Vult Freak DIY Kit Assembly Guide...
- Page 2 IMPORTANT: in this guide you will find many sections highlighted this way. Make sure you follow the indications. I hope you enjoy the module, and if you like it, share the Vult love with friends and enemies. Leonardo Laguna Ruiz...
- Page 3 Disclaimer: By purchasing a DIY kit you are aware that you are responsible of the outcome of your build. Before starting, verify that none of the parts has been damaged during the transport. If your build fails, we can provide a limited service to help you repair it.
- Page 4 Assembling the main board...
- Page 5 In this section we are going to build the main board. You will need the following parts: • The Core board (with all SDM parts) • 1 power connector (2x5 pins) • 4 female headers (1x10 terminals) • 1 push button (no cap) You can see the elements in the following picture:...
- Page 6 Start by soldering the 10 pin female headers. Insert the header from the component-side of the board and hold it. Solder only one terminal. Verify that the header is correctly placed before soldering the rest. The header should stand at 90 degrees. Repeat the same process for all four headers.
- Page 7 Now you are going to solder the power connector. This connector has a notch. The notch should be below the word POWER written in the board. IMPORTANT: Make sure you place it in the correct direction. NOTCH Use the same procedure as for the headers: solder one pin, verify that the connector is correctly placed and then solder the remaining pins.
- Page 8 To finish this section, solder the RESET button.
- Page 9 Your board should look like the picture s below.
- Page 10 Assembling the control board Part 1...
- Page 11 We are going to assemble the control board in two parts. IMPORTANT: Making it this way will simplify cleaning the board without damaging sensitive components. Locate the following components: • The control PCB • 9 jacks • 2 push buttons (with cap) •...
- Page 12 Start by soldering the two resistors. The orientation does not affect.
- Page 13 Continue with the pin strips using the following procedure. Insert the pins from the bottom (as displayed in the pictures). Then solder only one terminal. IMPORTANT: verify that the pins are correctly placed and that the angle is 90 degrees otherwise it will not be possible to connect the main board.
- Page 14 Place one of the two jacks displayed on the picture below. Hold it with your finger and solder it. Then place the second jack displayed on the picture and solder it. IMPORTANT: make sure the jacks are correctly placed otherwise the panel will not fit correctly.
- Page 15 Place (but do not solder yet) the remaining jacks. Once you have all jacks in position. Take the front panel and place it. Gently tight two nuts on the jacks that are soldered. With all the jacks in place, turn the board around and solder all of them.
- Page 16 Place the two push buttons with caps. Make sure they are sitting correctly on the board and solder them. The control board should look as in the picture below. IMPORTANT: now is a good moment to clean all the flux residuals in your board.
- Page 17 Assembling the control board Part 2...
- Page 18 In this section we are going to finish the control board assembly. Locate the following components: • 5 plastic shaft potentiometers (blue color) • 3 metal shaft potentiometers (green color) • 1 OLED screen • 1 screen holder You can see the components in the following picture As preparation, remove the nuts from the potentiometers if they are placed.
- Page 19 In order to simplify the mounting of the potentiometers, take some pliers and flatten the terminals as show in the pictures below. IMPORTANT: this is recommended because applying too much force to the plastic shaft when placing the knob can break it. These shafts break internally and become unstable or stuck.
- Page 20 IMPORTANT: When placing the potentiometers make sure they enter completely through the holes and that they are sitting correctly ovn top of the board.
- Page 21 Place all potentiometers as shown in the picture below. Once all of them are in place, put the front panel. Gently tight at least one nut of the jacks and one in the center potentiometer to keep it in place. IMPORTANT: verify that all potentiometers rotate correctly with the panel placed.
- Page 22 IMPORTANT: Before starting the next step, you can clean the flux residuals. Clean only from the back of the board. The cleaning solution may affect the potentiometers. Now it is time for the screen. Locate the screen and the plastic holder.
- Page 23 Remove the front panel. Place the screen in its position on the PCB and gently hold it while you flip the board to solder it. IMPORTANT: the screen is sensitive do not push it too much while holding it. Once you solder the pins of the screen, carefully clean the flux residuals of that section.
- Page 24 Carefully remove the protective plastic of the screen. Your control board should look like the picture below.
- Page 25 Final mounting of the module...
- Page 26 The final steps are straightforward. Locate the remaining parts: • Main board • Control board • Front panel • 9 nuts for the jacks • 3 nuts and washers for the potentiometers • 2 small knobs • 1 big knob IMPORTANT: Before starting, we recommend you to make a visual inspection of all your solder points.
- Page 27 Mount the control board on top of the main board as shown on the picture below. Check the orientation of the boards. If it’s connected backwards, you will notice that the boards do not align. Place the front panel and carefully tighten the nuts for all potentiometers and jacks.
- Page 28 To finish the assembly, manually turn all the metal shaft knobs counterclockwise (to the minimal position). Prepare the knobs by unscrewing the fastener and carefully insert them into the shafts. Start with the larger knob (central one) so you have more space to use your screwdriver.
- Page 29 The firmware of your board can be outdated. Check for the latest release at the main Freak page: https://www.vult-dsp.com/freak Make sure to subscribe to our mailing list in order to receive news about firmware updates or new modules. Enjoy your module and let us know how the build went!
