This project emulates a Roland MT module, and also supports external sound fonts, making it possible to emulate other modules like Yamaha XG, Roland Sound Canvas, etc.
Where in the past the software was very much connected to the hardware you bought, nowadays there are a number of very nice open-source home automation software packages available. The best thing is that it supports homemade hardware sensors and devices! We noticed that a lot of people like to make hardware themselves.
We also recognized a lack of well-designed circuits which can safely be built by people with not too much experience with electronics. Because of these issues we came up with the idea to start this website, espthings. And lastly, we will always ensure that the PCB will fit in a nice enclosure, so that the finished project not only looks nice, but is also safe. Our goal is to ensure that everybody can build our projects.

I prefer white soldermask with Black silkscreen,For 1. Many thanks to artist Cem Tezcan Blockmind for his patience and contribution to working together. It's emulation, but it's an obtainable package that won't cost more than my current car.
Widely considered to be the ultimate in retro MIDI-modules, it's the audio card every 90s PC gamer eventually found out was never actually an audio card and instead its own thing completely separate from your computer. The BulkyMIDI was my attempt at building something that would look nice on my desk while playing all of those classic Sierra games. After putting it together I took stock of all the features I had originally wanted on it, but I realized that I would need an additional board just to physically fit all of the connectors and larger components needed.
And so - work on extras board was started with the aim of implementing the following features:Providing an option for mounting RSmodules for level translationAn Atmega MCU for performing baud rate translation of these signals when connecting a real Roland MT to a PCs serial port. This is due to the MIDI standard using a baud rate that would be well outside of what the serial port can be configured to provide, at least without physically changing the crystal on the hardware.
Passive two-channel audio mixer, allowing you to mix the sound effects coming from the sound card with that of the MIDI module without dealing with configuring a mixer in software on the card. Able to mount a rotary encoder for use with the main module. This is the extras module, check out the related shared projects for any additional modules - these include extra functionality in addition to the faceplates shown in the images.
While the baud rate translation feature as well as the passive audio mixer can be used standalone, the extras board was designed for use with the main BulkyMIDI module. Tor-Eirik Bakke Lunde. Many of them might own an RA Breakout module or two For those who do, they will surely know about the problems encountered with using this particular breakout module The RA module, in itself, is a great piece of kit, and when used on a custom PCB, which was designed with all the little secrets of this module taken into consideration, is a pleasure.
Using the RA breakout module, in its existing form factor, does however present quite a few unique challenges, which, if you are unaware of them, can cause quite a few frustrating moments, or even result in permanent damage to the module What are these challenges:1 The module is based on the SX chip from Semtech and is a 3v device.
This causes many people, especially on Youtube, to assume that it is ok to send 5v logic signals to this module I have still not seen any Youtube video telling viewers to at least use a resister divider or logic converter People just don't know, and those that know seem to be keeping quiet! Adding logic converters is in fact specified by the datasheet.
My personal experience while researching this project 4 The existing breakout module is not breadboarding compatible, resulting in a floating assembly with wires going everywhere, which results in unstable connections etc Basically something similar to the picture below:In this picture, I have an existing RA Breakout Module, with an 8 channel Logic converter and an Arduino Uno clone, along with all the needed wiring to make this setup possible Quite a lot of wires indeed I also have the constant problem of many unnecessary wires, many of which sometimes fail straight out of the box, when prototyping something.
I partly solved that by designing a few dedicated PCB solutions, but that is not always ideal, Using a dedicated Logic Converter IC, and Mosfet based converters to make up the difference, on a breadboard compatible module, seemed like a good idea, so I went ahead and designed the following solution:The breakout board module is breadboard compatible, and also has clearly marked pins to indicate the 3v and 5v sides of the module.
I used Cytron's Maker Uno platform, which is equipped with some added goodies, in the form of diagnostic LED etc to make prototyping a lot easier. Serial ; Serial. Check your connections. As we can see, you need quite a lot more wires to make this work. I have quite a few of them lying around and have never really done a lot with them, due to the fact that I do not really like using MicroPython or CircuitPython, and also because the recently released Arduino Core for the RP still being quite new I decided to use a development board that I recently bought from Cytron, the Maker Nano RP, as it has all the added diagnostic features to make my life a bit easier, I will also include a test with an original Pi Pico board, to make it more accessible to everyone out there.
I obviously needed to change the pin numbers though, as the RP uses different pins for its SPI interface. The level converter can thus stay disabled, with its pins in tri-state high impedance mode. So, While technically not being a true standalone Pico, It makes my life easier and was thus used for the test, as I can be sure that the pins are labelled exactly the same as on the original Pico. The code used for the Maker Nano RP works perfectly, with no changes required.
They also function as expected. In SummaryWhen I started this project, I set out to solve a problem personal to me , that could potentially help a lot of other people use the RA Module for more projects and tasks.
The Breakout module in its current form can also be used with the RAh module Mhz Module without any changes. All GPIO pins are broken out, and accessible through full logic converted pins on both sides of the breakout module. I hope that this will be useful to someone.
I am also not releasing the full schematics at this stage, as I may decide to make some minor cosmetic changes in the near future. RA Breakout with Level converters 0 0. Digital Voltmeter:Digital voltmeters are used to measure potentials between two different points and they display the values in the form of digits accurately that is why they are more reliable to use.
The chances of making errors are less as compared to the analog voltmeter. They are more stable and provide a better interface to the user. Design Implementation:We are designing a circuit that will measure Voltages in Digital. All the inputs from those two potentials will be analog so we have to make all these values digital. We have many options to convert analog values to digital but we will use ICL IC due to its functionality as it will convert Analog to Digital and also give us output for 7 segments which will be easy for us.
Circuit Working:First of all, We need positive and negative voltages for our circuit. Negative will be supplied to ICL We will make these negative voltages with the help of a timer IC. NE IC will be used in Astable mode output oscillates at a particular frequency and generate pulses in the rectangular waveform.
In Astable mode, will provide us continuous voltage when it will be triggered. For positive we are using LDO. Then, we need two potential differences on pins 31 and After that, we have to make the internal clock circuit for ICL R1 and C1 will be used for the frequency of the internal clock. Then, we have to connect outputs from ICL with 7 segments. So, ICL will give 0 or ground to reference pins of 7-segments. Like if we have to display 1 on 7-segment we have to ground or provide 0 to B and C and it may vary for a different set of numbers that will be displayed.
Components Management Libraries:Before implementing the design in the PCB file, I have created the symbol and footprint of each component. Then I have uploaded each symbol linked with their footprint on Inventhub. Each component is attached to its supply chain. While designing the PCB board it is important to take care of the footprint and dimensions of each component.
Footprints should be exactly the same as per component size otherwise your design will not be perfect. Peel your photosensitized PCB's light protective film. If you aren't using transparency film for your PCB layout, you can use some baby oil to to make your paper printout translucent, this would allow the light through the paper to pass through.
I made a tutorial for white LED Strip version of it. Feel free to watch the video below. If you're using LED strips or fluorescent tubes, it will take around minutes of exposure time. The chemical used is lye or sodium hydroxide mixed with water.
The line mask traces would eventually appear. I grabbed my bottle of ferric chloride etchant and submerged the photo developed PCB on my DIY etching machine filled with ferric chloride. This would save you time from shaking your vat of etchant. It makes the etching process less tedious and a lot faster. Removing the remaining paint is important. If left on the board, it would give you a really hard time in soldering later on. I used my mini drill and a 0. On the other hand, I used my cordless drill and a 3mm drill bit for the high-power vias, through holes and screw mounts.
One of the limitations of homebrew PCBs are the lack of conductive through holes and vias. I designed the PCB to work with improvised through holes. Just strip a Guage 12 solid wire and solder it to link the high current lines from each side.
You can tin the traces with solder to cater more current and to prevent copper oxidation in the future. As stated from the previous step, homebrew PCBs do not have through holes. Be sure to solder the component's legs from both the top and bottom copper pads. Use your drill and 3mm bit to drill holes on it.
Homebrew PCBs also lack solder mask. Grab some ductape and insulate the bottom part of your heatsink to prevent it from shorting the copper traces from the top layer of your PCB. A shunt resistor is used in the circuit for current sensing and overcurrent protection. Instead of using those bulky high power resistors, you can use a solid wire of copper as a makeshift low-profile shunt resistor.
I stripped a Guage 12 solid wire, cut it to 60mm, bent it then soldered it to the board. A 10k Ohm NTC sensor must be connected to the pads on the board for temperature monitoring. I haven't tried omitting the NTC, but if you plan to omit the temperature sensor due to unavailability, just hook a 10k Ohm resistor across it. On the other hand, the inverter would still work with or without the 12V cooling fan.
Solder the transformer wires to the board and some Guage wires to the power input as well. You can add some XT60 or XT90 connectors for detachability. A filter capacitor must be added to smoothen the rough and spikey SPWM output from the transformer. Based on the datasheet, a simple 2. I made a simple breakout board for it, having three screw terminals connected in parallels to it.
A pair of wires goes to the transformer's HV output, another pair to the outlet and another pair back to the feedback input of the main inverter board. Before using the inverter with appliances, be sure to calibrate the output voltage. The assembled inverter project, comes with output voltage feedback regulation. This means, the user can set a specific voltage output and the inverter will try it's best to maintain that set output voltage, even when the voltage drops as the battery power source starts to drain.
There's a limit to this, if your inverter can no longer maintain the set output voltage, the error LED will blink and the inverter would automatically shut down. A 3S6P Lithium-ion battery pack was connected as the power source during the load testing. I chose li-ion for the test since each cell can dump 20A or current A in total.
As far as it goes, I was only able to reach around W from the output with a clean output waveform. The inverter shuts down by itself as I go above. Question 3 days ago. Hii, Can we connect 2 identical transformers in parallel to get more power from this inverter?
I mean can we connect two identical W transformers in parallel to get 1KW output power without having any problem with this circuit? I have two W transformers from two UPS of same brand and same specs. Question 2 months ago on Step 7. Question 3 months ago. Thank you for sharing this very interesting article. Answer 2 months ago. Works very well up to watts. I tried it with 24 volts and unfortunately it can not work more.
Question 2 months ago on Step 4. I have a sunyima w psw inverter with egs module, however upon connecting the lcd module, the lcd did not function and causes malfuntion to the ac output of sunyima inverter, what do i need to do to be able to use my lcd module? Question 2 months ago on Step 1.
Question 4 months ago on Step 1. Reply 7 months ago. Thanx for that. Reply 5 months ago. Hi If you did use the schematic that i think you did use, then look at your parts replacement diagram picture. Look at where your voltage regulator is at. Now look at the 10Ohms, diode , and 10k resistors is. Start at the top and number the sets 1 to 4. Set number 2 , the 10Ohms resistor and the 10k resistor must swap around Also at set number 4 the 10Ohms resistor and the 10k resistor must swap aound.
That will sort out your problem Look at the image that i have added and compare it to yours. Yes the output should be around 8v AC. There is nothing wrong with the circuit diagram. The problem is with the PCB outlay where the 10K resistors are at the wrong place. Send me your photo of your build PCB. Also the diagram that you used.?
I have same problem. I follow all the instructions exactly. It output 8v ac without transformer. There's no output on both side of transformer when I connect the transformer. I use 12 to v transformer. How can I fix the problem. Very interesting instructable!
