Relay operated power button

What you need:

a 5V relay module

Raspberry Pi

a bunch of cables

Explanation:

A power button on a computer case lets electricity flow between two power pins upon it being pressed, which is when the motherboard detects the button is pressed and reacts accordingly.

A relay is a specific kind of switch which lets electricity flow conditionally upon the flow of electricity in another circuit. The voltages involved both in motherboard power pins and on Raspberry Pi are generally low to not damage both, but we're taking extra precautions to electrically separate them both.

"5V relay module" here means that 5V is the voltage that is required for the relay module to work, while the controlling voltage can be lower. It being relay module it means it also has a flyback diode we'd otherwise have to provide ourselves.

Raspberry Pi's GPIO pins are programmable and can be controlled through Python code, and operate on 3.3V. Raspberry Pi also provides 5V output, but this one is not controllable.

By

connecting a power button to rPi GPIO pins

connecting the 5V voltage output pin from rPi to the relay module's Vcc input pin

connecting the ground pin from rPi to the relay module's groud pin

connecting programmable GPIO pins as the relay module's input pin

connecting the relay module's outputs (the normally open one and the ground) to the motherboard power pins

running some code on rPi

We can extend the power button functionality so Raspberry Pi can turn on and off our computer, while also still keeping the power button working.

Which is what I use to remotely turn on my computer on, by SSHing to rPi and running a script to turn the PC on while I'm away from home.

Why not Wake-On-LAN?

Wake-On-LAN has restrictions which makes it not as reliable as it could be, for example:

The ability to wake from a hybrid shutdown state (S4) (aka Fast Startup) or a soft powered-off state (S5) is unsupported in Windows 8 and above

The code and explanation for it in Part 2, when I get to writing it.

Matrix Connection: Few Pins, Many Options

4+4=8, 4×4=16. It often happens that a microcontroller or other chip has too few pins. You can use a more complex and expensive microcontroller, or you can multiplex the pins. Today I will describe one of the ways to do this.

In previous posts, we have already talked about decoders and demultiplexers, as well as shift registers.

In the first case, an n-bit binary number can point to one of the decoder outputs, the number of which is equal to two to the power of n.

For example, the 74HC138 3:8 demultiplexer chip allows you to light up eight LEDs or turn on eight relays using only three microcontroller pins or three communication wires between devices.

However, this scheme does not allow activating several outputs simultaneously. In the case of LEDs, we can take advantage of the persistence of human vision and constantly send different numbers to the inputs of the 74HC138. If the frequency of numbers changing exceeds 24 hertz, then it will seem to us that from 0 to 8 LEDs are lit simultaneously and continuously.

It should be noted that the more LEDs are used, the dimmer each of them will be. Although in some cases this is a good thing, the consistency of the overall brightness means that when more LEDs are turned on, they will not be blinding.

It is also possible to turn on several relays simultaneously through a decoder, although it is more difficult. Timing circuits similar to those used in running lights with slowly dimming LEDs will be required.

Thanks to diodes with RC circuits at the bases of transistors, relay coils connected instead of LEDs will switch off not at the same moment as the signal disappears from the decoder output but after a certain period of time.

If you keep the capacitor charged by periodically applying the corresponding number to the decoder input, the relay remains on. If you stop transmitting this number, the relay will turn off.

This is very similar to the operation of the Williams-Kilburn tube, one of the first types of computer memory in history. The electron beam scanned the cathode-ray tube screen, just like a television.

To turn the indicator into a storage device, engineers simply added a matrix of electrodes onto the screen and synchronized the modulation of the beam with the scanning of this matrix. Those areas of the glass where the electrons hit acquired a charge that would fade if not renewed.

Of course, this was not a fast memory by any stretch. And controlling a relay via an RC chain is also not fast. However, it fits a number of applications.

Each additional wire or microcontroller pin doubles the capacity of the demultiplexer. For example, 4 bits give 16 outputs. But the required number of decoder chips also doubles. For 4:16 you need two 3:8 chips, for 5:32 you need four, and for 6:64 as many as eight, and so on.

But the shift register allows you to transmit or read practically an unlimited number of binary bits using only three wires: one for data, one for clocking, and one for register latching.

Therefore, when paired with microcontrollers, to expand the number of pins, shift registers are most often used rather than demultiplexers.

Two CD4017 decimal counter-decoders have 2×10=20 outputs. But if you make a matrix where one chip scans the rows and the second the columns, you get 10×10=100. Or 9×9=81, as done in this matrix LED effect.

The same design is used in an electronic timer, where 6×10=60 LEDs are placed around the circumference of the dial and serve as the second hand.

As you can see, the matrix is not necessarily square or rectangular. It can be stretched into a line or closed into a circle, and in general, its elements can be arranged in the shape you need.

The decade counter U2 receives timing signals with a frequency of 1 hertz from the generator on the 555 timer. Using switch SW1, you can switch the chip to 'disable counting' mode, which means a pause in the stopwatch operation.

U2 counts to ten (from Q0 to Q9) and transmits the CARRY-OUT signal to the clock input of U1. Note that CARRY-OUT goes to logical zero when the counter has counted to Q5, and to logical one at the moment of overflow, when Q0 is activated again after Q9.

The CD4017 chip reacts just to the transition from low to high, so U1 will turn on the next row of LEDs exactly when U2 has turned off column Q9 and turned on Q0.

The active voltage level at the outputs Q0..Q9 of the CD4017 counter is high, and the current in the LED should flow from plus to minus, from anode to cathode, in the direction of the arrow. Therefore, the signals from the U2 outputs are inverted by the U3 CD4069 chip.

This chip contains six logic inverters. To count 60=10×6 seconds, we just need 6 lines of 10 LEDs. On the diagram, they look like rows and columns, but on the board, they are placed around the circumference of the dial.

After a minute has passed and Q2 has counted to Q6, transistor Q1 opens through resistor R2, performing two actions in our circuit.

First, it charges the capacitor C1, the voltage across which turns on transistor Q2 through resistor R3. This is exactly the same scheme that we've discussed above.

While C1 is discharging, the BZ1 buzzer will beep, not continuously but in 1 hertz pulses, since the positive terminal of BZ1 is connected not to the positive power supply terminal but to the output of the second pulse generator.

An asymmetrical flip-flop is constructed on transistors Q3 and Q4. A logical one from capacitor C1 through diode D1 and resistor R4, or from the power supply positive through R5 and button SW3, sets the flip-flop to one, which goes to the reset input of both counters, stopping the counting and resetting them to zero.

The diode is needed so that the buzzer is triggered only at the end of the count, not when the STOP button is pressed or a logical one appears at the output of the trigger through resistor R6, which latches the trigger into a high- or low-level state.

Button SW2 resets the trigger and starts the second count. If you made a multi-position switch that allowed you to choose which of the Q1..Q6 pins to connect R2 to, the timer could count not only up to 60 but also up to 10, 20, 30, 40, and 50 seconds.

And the last circuit for today is an RGB running light. Here IC1 is the familiar CD4060 binary counter, and 74HC138 is a 3:8 decoder that lights up one of the eight LEDs, LED1..LED8.

These are RGB LEDs, and the light color will depend on the state of the outputs Q8–Q10 of the IC1 chip.

000: white; all channels are on

001: blue-green

010: magenta; blue plus red

011: blue

100: yellow; red plus green

101: green

110: red

111: LEDs do not light up

As you can see, even to control RGB LEDs, it is not at all necessary to use a microcontroller. With two simple chips and three transistors, you can create the beautiful effect of a running, color-changing light.

Open source 24-channel USB high-voltage driver

When it comes to automation and control systems, there's often a need for multiple digitally controlled output terminals with high-voltage handling capabilities. Many existing modules are bulky, expensive, or require numerous additional components to function. To address this gap, I've developed a fully open-source, USB-controlled 24-channel high-voltage driver. This device provides precise, flexible control in a compact and user-friendly package. The project is open hardware, released under the CERN-OHL-W license, ensuring transparency from hardware schematics to firmware code. The driver module communicates via USB using a simple virtual COM port, eliminating the need for special drivers and complex setups.

At the core of the system are three TPIC6B595 shift registers, each supplying eight open-drain outputs that can handle up to 50V and sink currents of up to 150mA per channel. These registers are daisy-chained to achieve a total of 24 outputs. The outputs are designed for low-side switching and include integrated clamping diodes, making them suitable for driving inductive loads such as relays and solenoids. Data is clocked into the registers through serial input from a microcontroller, allowing for fast and reliable state updates across all channels with just a few lines of code.

The logic and communication for this module are managed by the STC15W204S microcontroller, a cost-effective yet powerful 8051-based MCU with enhanced UART performance and an integrated oscillator. This chip is paired with a CH340N USB-to-UART bridge, which presents the device as a standard virtual COM port to the host PC. Upon connection, the microcontroller listens for a set of AT-style commands sent over the serial connection. These commands are straightforward and user-friendly, for example, "ON=65280" activates the middle 8 outputs, "CLR" turns off all channels, and "VER" retrieves the firmware version. Additionally, there is a command to save the current output state to the built-in EEPROM, enabling the system to restore its output to a known state after power cycles. This interface design is perfect for scripting, automation, or integration with software tools such as Python, LabVIEW, or custom control GUIs.

The PCB is designed using KiCad and features a 2-layer layout measuring 75.25mm × 33.75mm. It includes 2.54mm pitch headers for output connections and is equipped with a USB Type-C connector. Power can be supplied through either USB or an external regulated 5V source, which can be selected via onboard jumper settings. The layout ensures clean signal routing and minimizes crosstalk or interference, even when switching high-voltage loads. Careful decoupling and protection components provide robustness for real-world applications.

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

The firmware for the STC15W204S is written in C using SDCC. It is easy to expand the command set, introduce new communication modes, or add timed control logic as needed. The current implementation allows full 24-bit output control using a base 10 numerical mask, making it both scriptable and human-readable. Thanks to the preloaded bootloader of the STC15W204S, firmware updates can be performed through the same serial interface. Details about this process are covered in the project documentation. Like the hardware, the firmware is released under the MIT License and is available in the project repository.

The system has been tested with a variety of 12V and 24V inductive and resistive loads, including relay banks, solenoids, and LED arrays. Since the outputs are open-drain, external voltages up to 50V can be safely switched on each channel making it ideal for a range of industrial, laboratory, or artistic applications. Output timing is reliable, with clean edge transitions observed during scope testing, and no signal integrity issues even during full 24-channel toggling. It is recommended to use individual heatsinks for the driver ICs when driving high-current inductive loads with this module. While the printed circuit board has heat transfer traces, the addition of individual heatsinks can increase the durability of the module.

Potential use cases for this module include automated test benches, home automation systems, signal routing for instrumentation, nixie tube multiplexing, and other high-voltage control tasks. The command-based protocol makes it easy to script operations or integrate this module into a larger system.

For those who wish to explore the schematics, command protocol, design rationale, and usage examples in greater depth, I have published comprehensive documentation and resources in the project wiki. This includes detailed assembly instructions, firmware flashing guidance, and tips on customizing the firmware for enhanced functionality.

Taming The Variable Speed Motor With Fluke Test & Measurement Tools

System reliability can be increased by being aware of harmonics and motor issues. The preferred ac variable speed drive technology, particularly for low to medium horsepower applications, is now pulse-width modulated (PWM) motor driving.

The technology is clearly superior to other setups since it is often less expensive, more efficient, and causes fewer harmonic issues for the input power lines. It might also be challenging to troubleshoot.

to comprehend the PWM driving issues that are commonly encountered better.

Let’s first look at the fundamental components of a variable speed drive. Its circuit is simple: the input circuit has a full-wave diode bridge that rectifies the line voltage and charges a capacitor bank to a dc voltage equal to the line voltage’s halfwave peak.

Fast-switching power transistors in the drive’s output stage transform the direct current (dc) into a string of tiny voltage pulses that are then applied to the motor leads.

The pulses’ height is the same as the capacitor bank’s dc value, but their width is modulated (or changed) so that the motor current resembles a sine wave.

In general, problems with variable-speed motor drives can be separated into two parts:

Power line harmonics generated by the drive’s input circuit

Motor difficulties caused by the output circuit

If we are going to tame the variable speed drive circuit, we need to divide it into two parts: input and output. The requirements for test equipment will vary according to which end of the drive we are measuring. variable speed motor

At the input, we will want to measure true-RMS current, plus harmonic current spectrum and power factor using a harmonic analyzer like the Fluke 1773/1775/1777 Power Quality Analyzer.

At the output, we need the same harmonic analyzer to look at the motor current and a fast oscilloscope such as the ScopeMeter 190 series to look at the motor voltage.

Both instruments feature high EMI shielding which is needed when taking measurements near the fast pulses on the drive’s output leads.

Troubleshooting motor problems

Winding insulation failures are the greatest concern for obvious reasons. Damaged insulation means replacement or rewinding, which can translate to a logistics problem if you don’t have a spare handy.

Winding insulation can fail from too much heat, too much voltage, or both. Unfortunately, a misapplied variable speed drive can deliver both simultaneously.

Overvoltage can occur when the distance between the drive and the motor exceeds the drive manufacturer’s maximum cable length specification.

The theory here does not involve the National Electrical Code. Instead, it comes from the laws of radio frequency transmission lines. Remember what’s happening at the drive’s output terminals.

Very fast rise time pulses are being sent down a set of conductors with distributed inductance and capacitance. That is, the cable resembles a transmission line. Each pulse travels down the cable at near the speed of light.

When the leading edge hits the motor inductance, it is reflected in the source, where it adds to the base value of the pulse. The resulting combination puts a sharp spike on the leading edge of each pulse. The spikes can be as high as twice the base pulse value. Longer cables make the problem worse.

To see this effect, you will need an oscilloscope or a handheld portable ScopeMeter test tool with a bandwidth of at least 10 MHz and the ability to trigger on a PWM waveform. (See Figure 3).

If you plan to install a variable-speed drive where the distance to the motor exceeds the drive manufacturer’s maximum cable length specification, be sure to ask for recommendations involving output filters or other methods of reducing the overvoltage spike problem.

Work safely Variable Speed Motor

The high voltage and currents present in electrical power systems can cause serious injury or death by electrocution and burns. Consequently, only trained, experienced electricians who have knowledge of electrical systems in general and the equipment under test should perform testing and modification of electrical systems.

We cannot anticipate all possible precautions that you must take when performing the measurements described here. At a minimum, however, you should:

Use appropriate safety equipment such as safety glasses, insulated gloves, insulating mats, etc.

Be sure that all power has been turned off, locked out, and tagged in any situation where you will be in direct contact with circuit components. Be certain that the power can’t be turned on by anyone but you.Work safely Variable Speed Motor

Read and understand all of the applicable manuals before applying the information in this application note. Take special note of all safety precautions and warnings in the instruction manuals.

Do not use instruments on applications for which they are not intended, and always be aware that if the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
