6-channel speaker selector

At the beginning of 2018, we developed the first version of the 6-channel speaker selector using PIC16F88 MCU and ULN2803 Darlington transistor array. In this new design, we redesign it with low-cost MCU and Darlington transistor arrays. This design also provides the same functionality as the 6-channel speaker selector switch we designed earlier.

This new speaker selector uses STC15W201 MCU. This MCU is a low-cost 8051 MCU designed by STC micro. At the time of this writing, the STC15W201 can obtain for less than US$ 0.8. To drive the seven segments and to control the relays, this design uses the popular 74HC595 8-bit shift register ICs.

To select each speaker channel, we use pair of 12V DPDT relays. These relays interface to 74HC595 through a ULN2001D 3-channel Darlington transistor array IC. This 3-channel Darlington driver IC is functionally equivalent to the famous 8-channel ULN2003 IC. This ULN2001D version is an 8-pin IC and is available in both DIP-8 and SOP-8 packages. 

This new board is designed to work with a 12V DC power supply and in our prototype build, we use a 12V/5A SMPS unit to power the whole system.

To get the optimal results with this circuit, use an Omron G2R-2-12DC or an equivalent type of relay with a coil current lower than 100mA. 

The firmware of the STC15W201S is developed using SDCC. To flash the MCU, we use stcgal. Thanks to the built-in bootloader, we can program this MCU using a generally available 5V USB to UART module/dongle. 

The complete build process of the speaker selector is shown in the video below:

The functionality of the firmware is almost identical to the old PIC16F88 firmware. After powering up the system, the active speaker channel is displayed on the seven-segment display. To switch to a different speaker channel, press the button repeatedly with short intervals. 

To mute or disconnect the current speaker channel, press and hold the same button for more than 3 seconds. 

As described above, all functions of this circuit can be the control using a single push switch.

The PCBWay sponsored this project. PCBWay offers high-quality PCB manufacturing and assembling services. Also, they offer CNC and 3D printing services. The Speaker selector PCB is available to order from PCBWay. Check out the PCBWay website for its manufacturing capabilities and pricing.

Factory of FUZZ (fuzz factory clone)

I’m always looking for the cheapest way to build pedals. I found these boards on OSH Park.com. Besides being a service for prototyping boards it’s also an open source repository of projects uploaded by the community. A board uploaded to OSH Park marked public can be ordered by anyone. The search function is not so great but it is searchable. I spent a day searching OSH Park for stompbox projects and found more than a few things that look worth building.

The OSH Park standard service is $5 per square inch with the requirement that you order three boards, and shipping is free. This usually cheaper than ordering boards from vendors but there is no support. One of the projects I found was a this Fuzz Factory. It looked well laid out and the cost was $7.75 for 3 boards, about $2.50 per board, which was pretty reasonable.

Order some of these boards here: https://oshpark.com/shared_projects/xaBILSTV. Check out my projects page for links to some OSH Park boards I designed. I have documentation here on my site.

With no build Docs you’re on your own. The Fuzz Factory is not a complex pedal and the schematic is readily available. Some OSH Park projects will link to documentation and other do not. This is a good way to level up your skills!

Getting Started

The Fuzz Factory is not a hard pedal to clone. The toughest part is wiring the pots. Getting a board where the pots mount directly to the board is a great help. Here three of the five pots mount to the board and two require off board wiring which makes a pretty easy build.

The Fuzz Factory has only a handful of parts. I soldered everything except the pots and the two germanium transistors. You’ll want to test a few transistors if you’re using germanium to get some that sound best. That said really everything even silicon can sound good in this circuit.

The Enclosure

For the enclosure I used a black powder coat 1590B from Tayda. For the logo and labels I milled the box using a desktop mill. The powder coat is removed to reveal the design. I created the design in Sketch on the computer exported some SVG files and loaded these into the mill.

Switching

I decided to try out a relay switching system. This uses a soft touch momentary SPST switch and some circuitry. I used boards from DIYGuitarPedals.com. Their system uses some discreet logic and a relay to handle switching and the status LED.

The PCB is designed to fit a 1590B or larger enclosure. It requires a few parts which are mostly easily available. The relay is available through Mouser. Erik over at DIYGuitarPedals was generous enough to send me two boards and the relays, thanks again Erik! Check out their web site and their YouTube channel.

The system uses a relay which is an electromechanical switch in a little box. The switch in this case is the RY9W-K. It’s a DPDT but rather than being engaged by a button or lever it’s engaging by an electrical voltage applied to a control pin.

In the picture below you can see the relay has 8 pins. The 6 pins on the left are the switching connections, each row is one switch, the center is the common connection that bridge to the outer connections depending on the state of the switch. Hey those six pins on the left are just like the pins on a regular DPDT switch-. The two pins on the right are the control and ground.

The board, relay, SPST switch, and other parts make up a single assembly that replace the 3PDT switches typically used for guitar pedals. You can see it neatly fits the lower bout of the 1590B enclosure.

Here is what the whole system looks like assembled. This is complete and could be dropped into any pedal replacing the standard blue 3PDT.

How does it work?

Unlike many relay systems that rely on a micro controllers this circuit uses only discreet logic. There are pros and cons to each. Using a micro controller requires some extra circuitry since the Micro Controller runs on 5v. They can be proprietary since someone has to write the software that runs the system. Using a Micro controller you can fit all the logic into an 8 pin DIP and add new features or up date the existing code. Using discreet logic your system can run on 9v, might have fewer parts, and won’t suffer from software bugs.

This system relies on the 4011 quad NAND gate to handle the switching logic. Check out this video for a more in-depth explanation of the switching logic.

Assembling the NAND Bypass board is pretty easy. Easier than making the Fuzz Factory board. It’s got very few parts and there is plenty of room to work. If you wanted to give this type of switching a try this would be a good place to start.

Building and wiring the Fuzz Face

The board mounts the three 10k pots and will accept 9mm or 16mm pots. If you are trying to fit this into a 1590B box in portrait orientation you’ll need to use 9mm pots! The two 5k pots are mounted off board. You could also build this in portrait with all 16mm pots.

I mounted the pots in the enclosure then soldered them to the board to make sure they were perpendicular to the enclosure.

I had some ribbon cable salvaged from an old computer. I used this to wire the off board 5k pots. The board marks the pins 1 and 3. Pin 1 also has a square pad. I used 16mm pots with pins that stick out perpendicular to the shaft. I cut a couple pieces strip board to interface the wires and the pots. This made for some nice clean wiring.

The bottom of the PCB is pretty close the corners of the enclosure. I’ll have to be careful it doesn’t short out there! This was a test fit. I needed to mark the positioning for the power, input and output jacks, then disassemble everything and drill these.

Once I got everything drilled I added some wires and reassembled everything. I realized I needed to move the two pots in the second row inboard a millimeter or two. You can see I had to file the holes a little.

I also installed the switching board. I stuck a little piece of wood to the side of the switch to brace it against the back of the enclosure. There was no way to brace the switch when tightening the nut.

You may have noticed the two germanium transistors are missing. Since these are notoriously inconsistent I decided I wanted to audition a few before selecting which would be used for this project. I have a bag of 40 I’ll test and measure these to find suitable pairs.

I have this TC1 Multi-function Tester. This cost about $17 on eBay. Well worth the money. It tests resistors, capacitors, diodes, transistors, and more. It will tell you all of the most useful information. It will also differentiate NPN, PNP, JFET, and MOSFET devices, and tell which pin is the base, collector, emitter, gate, source, or drain. Super handy.

Germanium transistors have a high degree of variation. Their hfe and leakage is very inconsistent across devices with the same part number. There is a lot of debate about what hfe values work best for different circuits. Some people like to judge by the numbers others like to use their ears. I’m going to go with a hybrid approach use the numbers to get in the ballpark and then audition by ear.

I measured all of the Germanium transistors in the parts bin, marked each with a number and made a spreadsheet of all the values I measured with the TC1.

https://docs.google.com/spreadsheets/d/10O7FYfs_f0x301CYvcvC7pWFFp8Ld2-e3oANXK-AOtc

This is a Fuzz Factory I built using a board from AionFX, it has a few extra knobs. I used sockets for the transistors. I figure I can plug some transistors into this to hear how they sound before soldering them into the new Fuzz Factories.

Here I wired up everything in the box. The NAND Bypass board is well laid out and labeled making wiring easy. Input and output jacks go to the input “In Jack” and “Out Jack” and the input and output from the PCB go to the “To PCB Input” and “To PCB Output”. It’s paint by numbers really!

At this point I gave it a test. I the LED worked, and bypass was working. So we’re goo to go. The last step is finding and installing some Ge transistors.

Tested some transistors in the green fuzz factory and decided on 1 and 9 from the spreadsheet. They had numbers that seemed to be the right range and sounded good.

Taco Fry Fuzz #1

The first us out of the way time to audition a couple more transistors and make the second box.

Tested a few more transistors and decided on #60 for Q2 70 hfe, and #21 for Q3 190 hfe. These sound good and we’re very close to the values for the first pedal. Which should make these sound very close.

What does it sound like?

The Fuzz factory is a highly variable fuzz. The sounds range from standard distortion to fuzz into high gain. It’s possible to dial in gated fuzz and zipper sounds. Not all of it useful in many cases. It’s all fun and inspiring.

An Easy Guide to PCB Solid State Relays

A steadily expanding trend over a very long time with all of the producers of electronic gadgets is “smaller is better”.

Configuration designs for anything from cell phones, PCs, to bigger private apparatuses and sound/video systems continuously clash with the market-driven necessity for more modest bundles with “better than ever” in excess of their archetypes.

This interest not just tests the mechanical plan capacities of the engineer, yet makes a necessity for more modest and frequently more “power-dense” electronic segments, too.

PCB Solid state relays are regularly utilized in numerous business and mechanical applications, including plastics and bundling machines, proficient food gear, research center broilers, dramatic lighting frameworks, clinical hardware, renewable energy systems, and other equipment, etc.

They are along these lines “practical objectives” for engineers that are attempting to decrease the size of their general framework.

This makes the PCB Relays single-in-line bundled (or SIP) Relays an ideal option in contrast to discrete or board mount arrangements.

Advantages of PCB Solid State Relays

The primary advantage of using PCB Solid State relays is, fittingly, space savings. The bundle is minuscule contrasted with other SSR bundles, which takes into account the utilization of numerous transfers on a solitary PCB.

Clinical equipment, for example, a dynamic dialysis machine, is one illustration of an ideal contender for a PCB Solid state relays. As the interest in homecare systems increases, so does the interest for less heavy and more compact clinical equipment.

PCB Solid State relays are broadly utilized in an exceptionally distributed scope of utilizations, areas, and ventures, including:

Industrial controls

Motor control

Robotics

Medical devices and patient/ equipment isolation

Instrumentation

Multiplexers

Data acquisition

I/O subsystems

Meters (watt-hour, water, gas)

IC hardware

Home appliances

How to install PCB Solid state relays

A couple of extra points that makers should consider while choosing Relay. That rotates around the mechanical parts of the item.

Not at all like conventional board and DIN Relays are PCB mount SSRs commonly fastened into a circuit board. Which will have lower force-current capacities and assembling interaction frequently planned around more modest parts with less mass.

To guarantee the unwavering quality of the assembly. Thought should be given to issues like the binding and framing of the SSR, just as the plan of the PCB itself.

How does the PCB relays work?

PCB Relays are, as the name suggests, supposed to be mounted directly onto a printed circuit board.

This makes for speedy and clear establishment on motherboards and different kinds of PCB. Either by means of push-in pin fittings or with a necessity for fastening straightforwardly to the PCB surface.

Conclusion

PCB Solid state relays offer the same technical benefits that a board or DIN mount SSR has over electromechanical relays. Including significantly improved future, no contact skipping or arcing, quiet operations. Zero-intersection capacity, low force information, and high protection from stun and vibration.

In any case, they do as such in a package that takes into consideration more modest and more adaptable system plans.

Given the appropriate thought we’ve laid out here, a PCB relay will far outlast the gear in which it is utilized, just as the makers that planned the system.

Boss Muff

I love Boss pedals, they are bomb proof, have a great form factor, work well, and look great. They don’t make a couple effects that I like. For example you can’t get a Big Muff in Boss. I had the idea to rehouse some effects in Boss enclosures. Here is the Boss Muff.

The Boss Muff is a Green Russian Big Muff in DS-1 enclosure

Sourcing enclosures

I couldn’t find empty Boss enclosures for sale anywhere so I had to recycle. Boss pedals keep a good resale. It’s hard to find these for less than $40. Often used Boss pedals go for $100 or more. I didn’t want to pay $40 for an enclosure but I wasn’t going to pay $100, especially for something I might want to keep.

After some research on Reverb I found the Boss DS-1 was cheapest. Typically they go for ~$40. The historical prices show sales a range of $25 to $45. Reverb says the estimated price is $25 to $35.

Check out historical sales on Reverb here: Boss DS-1 Distortion (Silver Label) 1994 – 2021

Note! New Boss DS-1 and Boss SD-1 go for about $50. If you have a discount or see a sale it might be good to buy a new pedal since places like Sweetwater offer free shipping.

Watch the shipping! People will ask $15 on average which is really high for something where the asking price is $40. Typically I can mail a pedal for $6 to $10 USPS.

This is the donor DS-1 for ~$40 from Reverb.

The enclosure and parts

The enclosure is great, it’s pretty spacious, pre-drilled, and it comes with some usable parts. It’s even partially pre-wired!

It comes with jacks, LED, battery clip, a momentary SPST switch, knobs, and some pots. It also comes with a DC power jack but, this was mounted to the original PCB, there will be nothing to anchor it to when I replace the board so I couldn’t use it.

The Jacks are useable and the wiring can be repurposed. There’s nothing special about these jacks. It is interesting the way they fit the enclosure. You don’t need hold them from the inside when you tighten the nut.

The LED is mounted to a small board. I used the LED and board. I just replaced the wires because I needed a little more length. The LED is a typical red 3mm type. Nothing special here.

I usually don’t use a battery but, since the clip was there and partially wired it was easier to just keep it! I wired up the battery snap for this build.

I went with a relay switching system, more on this below, the existing switch worked well for this! I left the existing switch in place along with the wires.

The pots from the DS-1 were B100k, B100k, and B20k. Since I was building a Big Muff I needed 3 x 100k pots. I kept two of the original pots and replaced the 20k pot with a A100k pot. The two B100k pots were 16mm and B20k was a 9mm pot with pins at 90 degrees. It looks like you could fit 3 x 16mm pots but I didn’t test this theory and just brought another 9mm pot.

Pots from the original DS-1 mounted to the new PCB with the original ribbon cable.

All of the pots had a small PCB with a ribbon cable running to the main PCB. I used these small boards and the existing ribbon cables.

Note! The ribbon cables use thin solid core wires. These seem like they would break easily but Boss glues both ends to their respective boards with some kind of industrial glue, maybe epoxy. I took their lead and glued the end of the ribbon cable to the PCB with some gorilla glue. The glue anchors the end of the wire where it’s prone to breaking.

They did the same with the DC jack, this type of jack is prone separating from the board on other pedals, I’ve fixed a few of these in the past. Not on Boss pedal! The jack is soldered then glued to the board! I’m surprised other manufacturers haven’t caught on to this.

I reamed the enclosure to fit a standard DC jack. I used a couple of those plastic washer to keep the jack from extending too far out of the enclosure.

The knobs are nothing special. They use splined knobs rather than knobs with a set screw. I kept the pots so I kept the knobs. I had to get a new knob for the replaced 9mm pot since I couldn’t get a 9mm pot with a splined shaft or at least a 9mm pot with 90 degree pins with a splined shaft.

Switching

Boss uses an electronic switching system paired with a buffered bypass. Seems like you could use this some how. This might be a future project…

For this project I decided on something I could more easily understand. I went with a relay switching system. This is an electronic DPDT that includes a circuit that also handles the LED. The system uses a Microcontroller that tracks the SPST, powers the LED and switches the relay.

Madbean Softie (left) and Rabbithole (right) PCBs

I went with the Madbean pedals Softie system. It has some good features. It is also true bypass. The effect path through the relay is essentially a wire connection all the way through. A nice feature of the Softie is if the power goes off it switches to bypass. The relay has an estimated failure of 100k clicks so it should outlast a stomp switch.

I chose the Softie 2 board. Madbean offers three PCB versions 1, 2, and 3. The Softie 2 is made for 1590B sized boxes. I thought this would good but I wasn’t thinking in 3D. This board mounts parts on both sides which makes it taller even though the footprint is smaller than the other boards. I still made it work but, a wider flatter board, with all the parts on one side, would work better in this enclosure.

The Softie works well. Assembly is easy. Some of the parts you’ll need to order from Mouser so it won’t be as cheap as a 3PDT switch. Wiring is easy. Overall I’d recommend this for other projects.

Cost estimate to build a Big Muff in a Boss enclosure

But What about the finish?

I didn’t paint the enclosure. This would have added a lot of time, cost, and effort to the project. Admittedly it would have looked far more amazing when it was finally finished. I was not super excited to try and peel off that rubber pad on the foot switch and glue it back on. You might be able to mask this. Also sanding the enclosure did not inspire me.

I think I might just slap a label on this to remind me what’s in the box. As it is the existing labels: Tone, Level, and Dist work for the Big Muff. Though the arrangement is not what I would have done. The small center knob is Level. Intuitively I reach for the upper left when I want to adjust the Volume. Sounds!

Here is a short video clip of a stock Boss DS-1 next to the Boss Muff. I built the Boss Muff to the spec of a Green Russian Big Muff. Not sure if I made a mistake or if it’s the nature of the green Russian but it has lots of bass. This would be great for bass.

Conclusion

So was it worth it? The whole process was easier than I thought it would be. The cost was higher than building other projects but not as high as I thought it might be. Reusing parts from the DS-1 saved on costs for pots, jacks and knobs which are some of the more expensive parts.

I could have shaved the costs down if I could have traded for a Boss pedal or watched Reverb for a couple weeks looking for a deal. I just bought the cheapest DS-1 I saw and paid the asking price. Besides waiting for a $25 DS-1 to show up on Reverb and then see $15 shipping is a little anticlimactic.

Overall the experience was informative. I think I enjoy having the rehoused Big Muff. I’ll probably use this pedal. The process revealed some of the tech used by Boss in their pedals. I’m definitely going to do a follow up…
