Tale of two vintage Radio Shack multimeters, a digital one from the 90s and another analog one probably 20 years older.

Trying to debug what is wrong with our Swiffer (tm) electric mop, which only goes click now instead of bzzz when you pull the trigger. My digital meter was going crazy with strange readings causing me to take more of this thing apart till I realized the 9v battery in it was probably low and causing it to act strange.

Not having a spare 9v battery, Hauled out this analog meter which in theory probably also has a dead battery in it, but it's only for the ohmmeter and the voltmeter is happy as a clam and instantly told me what I needed to know.

I'll get a new battery for the DVM... But I think I'm much more likely to reach for the analog meter. Not only is it nostalgic for me from my youth but it's actually still better in a lot of ways

[literallymechanical]

Kimchi (left) may or may not have thrown up on @fishteriously's air purifier (right) and killed it. Either way, it was dead and out of warranty, so we grabbed a multimeter and pried it open.

Ok so, the 12V power supply was working, regulated 5V power was getting where it was supposed to go, all the cables were secure and I couldn't find any shorts, but the thing was still dead. Also there was a mysterious brown goo all over it (mostly wiped off in this image).

Now, I'm a mechanical engineer, not an electrical engineer. But from what I understand, this state – where the power is good, but nothing is happening and there's something gross on it – is known as "turbo fucked."

But like, okay, once you get rid of all the bells and whistles such as "a user interface" and "selectable speed" and "digital electronics," an air purifier is just a fan, a cowl, and a filter, right? All analog components. There are plenty of places here to tap 5V power, so if I disconnect the microprocessor entirely, grab a jumper wire, and short 5V directly into the PWM input...

lol. lmao. It spins.

There we go! All put back together and working like a charm. I mean, the LED's and computer aren't connected to anything, but the fan is going and it purifies the air just fine.

I didn't like the look of the dead pcb sticking out of the top. But the wire cutters were on the other side of the room, and I hurt my fingernail last time I futzed with the ribbon cable...

Perfect. Good as new.

[ptiautiste]

Finally...

I was looking for a really good shortwave receiver for at least a decade -an old tube equipped one of course. The problem getting one nowadays is that they were only produced in small numbers half a century (or more) ago, since then most are scrapped, botched, altered or corroded cause of bad storage -or all together. So if you have the chance getting one today you most likely will buy a 'construction site', needing hundreds of working hours for restoring it in a good working condition.

But after a looong search finally i had real luck. A big wooden crate was delivered on a pallet.

In this crate was one of the -for my opinion- ugliest shortwave receivers ever built, but at the same time also one of the best ones: a Rohde + Schwarz EK07.

Built in 1958 this one was a storage unit from the German Army. Well stored, regularly maintained and serviced, not altered, not botched, never used. So it is in nearly mint condition. It wasn't cheap but getting my hands on this was just sheer luck. Without doing anything: it's in perfect working order. No potentiometer, no switch crackles, every tube checks new -of course you can check all the tubes in the radio itself without removing them.

The manufacturer is more known for it's precision Lab-Equipment and less for it's shortwave receivers. This is also because their receivers weren't consumer or amateur gear, this was pro gear by any means. They were used in applications like coast guards or military surveillance and such. Always things where equipment costs doesn't matter -only the outcome. So back in 1958 when this unit was manufactured you could buy at least two brand new cars for the same amount of money. In exchange for this you got a masterpiece of german engineering and craftsmanship -and also an electro-mechanical nightmare if anything fails and you're not absolutely familiar with it's guts.

Fancy? No, there's absolutely nothing fancy on these. These are absolute workhorses, designed for doing an important job 24/7/365 for decades. Just take a look to that bandswich gear in the photo above. How often you have to switch over the bands until this would be worn out? Millions and Millions of times... And nope: this dark residues at that drum on the left and box below isn't mold or such. These are completely silver plated so it's just the darkened silver.

As you may see, most of the structural parts are made of die-cast and aluminum, so from the materials used it's relatively light weight. But all that built-in sturdiness and shielding adds up to staggering 147lbs/67kg. It's only a receiver, not a transmitter or a power amplifier.

Tubes... and more tubes

If you're not familiar with tube radios: your average AM (and shortwave) Radio from the 50's or 60's used 4 tubes (without the rectifier if this was a tube). Your trusty Hammarlund or Yaesu shortwave receiver from that time would have somewhat from 8 to 12 tubes -and these were quite good and sensitive receivers! This Rohde + Schwarz counts 28 tubes.

Some tubes here, some there, all fully shielded. But why the hell that much? The answer is quite simple: stability. On every count. Constant and stable gain over all bands and for a looong service time, stunningly stable VFO frequencies and all that stuff. No, they used no consumer tubes like in your TV or such. All of them are out of the 'commercial'-tube-series with a guaranteed service life of at least 10000 hours like in every aircraft of that time or such. Failing was not an option, this HAD to work.

Speaking about stability and accuracy:

this of course isn't digital stuff -it's purely analog. In the pictures below you can see the dials. Just add both frequencies and you know where you are -here on 29.630MHz or 29630kHz.

As you see: your readout is easily accurate down to less than 500Hz. So you can read at least 500Hz out of 29630000Hz. With other words the accuracy of your readout is 0.001687% in this case. Your average modern digital multimeter would be proud if it came only near to this 65 year old contraption.

Of course that large dial in the picture on the left isn't the only one. There are 12 of 'em, mounted on a drum and rotating according to the selected band. Giving you a simple S-Meter like in other shortwave receiver was of course also not possible.

Instead they provided you with a Voltmeter which displays directly the input voltage at the antenna input -and the threshold voltage for the 'Squelch' (if you have set that) which isn't a normal squelch. If activated it doesn't cut your Audio, it reduces the Gain instead with a settable time constant, so it acts more like a active noise cancelling between any signal -also between any dash and dot if you're receiving CW (Morse Code). Besides that you can choose your IF-Passband between 150Hz and 12kHz, have a absolutely stable BFO, a good Envelope Detector for AM-Reception and a perfect Audio Stage - that's all.

Speaking of the Audio Stage: 2W undistorted output power from a single end class-A is more than you need with a good speaker. McIntosh ® would call that circuit 'Unity Coupled', further a E88CC for the Audio-Preamp. We're talking about an Shortwave Radio, not an 'High-End' Audio Amplifier. Wanna take recordings of what you hear? No problem: here's your Line-Output, symmetric, 600 ohms, transformer coupled and with +10dBm (if you want) and in accordance to all Studio-Standarts. Sound quality for AM Broadcasts? With a passband switchable up to max. 12kHz for the IF better than the majority of stations can provide.

Precise?

So far so good, but what's about the heart of every shortwave receiver: the Oscillator or VFO? How stable and precisely does it beat after 65 years?

In your trusty -and quite good- Hammarlund or Yaesu amateur Radio from these days the VFO usually is equipped with two tubes: the Oscillator itself and the buffer amplifier -both sometimes also united in one bulb. If i hadn't lost track here they used 12 -and tons of other stuff. So that frickin VFO has a component count which is easily about the order of a complete shortwave receiver.

What the hell is all that stuff about -and wtf they had for breakfast back then? The answer is again simple: precision and stability.

As i said: this thing is 65 years old and i touched nothing. Of course I checked how much it's 'off' in terms of the frequency. After warming up for 20 Minutes i checked it every 1000kHz from the bottom to the top of its range. It was a bit different between all points, at some less than 50Hz and about 1kHz worst case.

My Lab-Equipment is quite good and precise, but for these low errors the tolerances of the measuring equipment has absolutely taken into account. So i made a separate measurement only for 10MHz -with the aid of a frequency standard sourced from an atomic clock. So this was 'the real thing'. After warming up for an hour i measured for 15 Minutes. The deviaton was between -717 to -722Hz. Including the error of the dial. This means frickin' 71.7...72.2ppm. PPM -parts per million! 65 years after manufacturing.... Just absolutely stunning -and with what freaking kind of equipment they had calibrated this back then??? Just have in mind: this is pure analog goodness, not a modern PLL. How the f***k they got there? Here's the clear link between a manufacturer of high-grade Lab Equipment and a shortwave receiver. I'm just stunned over the knowledge of the engineers who designed that circuit back then and the precision this was built.

All without doing anything and all it's original capacitors. Yap, i could realign that but tbh it's just wayyy to less been worth the effort. So it will stay as it is.

Nope,

you're not provided with that fancy stuff your new digital or SDR may have on board. There's no notch filter, no panoramic display -not even SSB! Why the hell they just 'forgot' all these things? The answer is easy: it's modular. The EK07 is just the 'mainframe', everything else you wanted to have can be added as external components you had to buy separately -also for tons of money of course.

Wanting SSB? Just add this:

35kg/77lbs and 18 Tubes more -to mention it's also a synchronous detector for AM is not worth the effort. Panoramic display, digital frequency counter, Teletype Adaptor, a remote control for controlling that beast over a telephone line? FM? Diversity reception?? No problem, you had just buy it. Everything of course with the same standards for precision and build quality.

The outcome...

Yea, i spent a good amount of money getting this -but in my opinion it was worth every dime. I wanted a good tube receiver and i got a really good one. Compared to upper class modern Radios it's still a very good radio. So the only thing I have to add is an external SSB/AM-Synchronous Detector. The originals are nearly impossible to get today, so i decided to build one. It's on the way and i will give you the results later. So stay tuned...

Story time!

So our professors are mostly engineers (others are either mathematicans or physicians) so they have experience big time in the field.

For our analogical electronics lab we were working on the circuit of chargers (transformer + diode wheatstone bridge) and one of the components was faulty and considering both the wheatstone bridge and transformer were made by component we needed to start trouble shooting one by one

so we took 10 minutes of plugging unplugging then testing til we reached our wheatstone bridge and tested the second diode

our professor notices us struggling and wonders if we were doing alright then he realizes we are testing for voltage drop between component and you know that moment when nerds in anime go: " (readjust glasses)"

We just saw the experience gap when he switches the multimeter to measuring intensity and told us: "you can keep testing all components until intensity is zero without unplugging this will be where our problem is" and in 2 minutes he figures out what we would have taken more than 10 minutes to find without figuring ourselves and since this day I will forever remember that technique our prof is. It's the exact moment when the mentor shows his full power to the student in media

Instrument Rental for Engineers: Choosing the Right Electrical Measuring Devices

Electrical measurement devices are vital for assessing, tracking, and evaluating electrical circuits and systems. These tools are key to ensuring the safety, precision, and optimal performance of electrical operations across industries such as construction, manufacturing, and electrical engineering. For top-quality electrical measuring instruments, Arabcal provides reliable and accurate tools to meet all your measurement needs, ensuring superior performance and safety in every application.

This blog will guide you through various types of electrical measuring devices, including the multimeter, ammeter, voltmeter, and wattmeter

Let’s explore their practical uses and learn how to operate these measuring devices properly to ensure precise results.

1. Multimeter

Multimeters are among the most widely utilized electrical testing instruments in labs. They are capable of measuring various electrical parameters such as voltage, current, and resistance. These devices are frequently employed for diagnosing issues and performing upkeep on electrical systems.

2. Ammeter

An ammeter is used to measure the flow of direct or alternating current within an electrical circuit. The measurement is expressed in Amperes (A). Ammeters are installed in series with the circuit to ensure accurate readings. They are designed with very low resistance to permit a high current flow. Ammeters are capable of detecting a wide spectrum of current levels.

When the current to be measured is in milliamps or microamps, specialized instruments called microammeters or milliammeters are used. There are two primary types of ammeters – analog and digital. Analog ammeters display the current using a pointer and scale, while digital ammeters show the reading on a digital screen.

3. Voltmeter

A voltmeter is used to measure the voltage or electrical potential difference between two points in an electrical circuit. Voltage is expressed in volts. Voltmeters are generally connected in parallel with the component or circuit being measured and are designed with very high resistance to limit the current flow through the circuit.

Commercial voltmeters typically use an electromechanical system where the current is converted into voltage before being measured. In contrast, electrostatic voltmeters directly measure the voltage. Similar to ammeters, voltmeters come in two types – analog and digital.

4. Wattmeter

A wattmeter is used to measure the power or the rate at which energy is consumed in an electrical circuit. Power is expressed in watts (W). Wattmeters are commonly employed in three-phase systems to measure both apparent and real power in a circuit. They are also useful for assessing power supply efficiency and calculating energy costs.

Wattmeters are connected in such a way that they measure both the current and voltage in the circuit, then compute the power using the formula P = VI (where P is power, V is voltage, and I is current). These devices are often used to track the power consumption of appliances and evaluate the output power from generators and other energy sources.

How to Select the Right Electrical Instrument?

It’s also crucial to take into account the measurement range that the instrument can handle. Some devices offer a broad range of measurements, while others are limited to a narrower scope. Furthermore, the accuracy of the instrument is an important factor. The greater the accuracy, the more precise the readings will be.

It’s essential to remember that to achieve precise measurements, the appropriate range or sensitivity of the meter should be chosen. For instance, using a meter with a low range to measure a high current will result in inaccurate readings. Similarly, using a meter with a high range to measure a low voltage will also lead to unreliable results.

When operating these instruments, it's crucial to adhere to proper safety guidelines to safeguard both yourself and the equipment.

5 Common CNC Router Controller Issues and How to Fix Them

In the world of modern manufacturing, CNC routers are indispensable for achieving precision and efficiency. However, even the most advanced machines are vulnerable to technical glitches—particularly with their controllers. A CNC router controller is essentially the command center that translates software instructions into physical movement. When something goes wrong here, it can bring your entire operation to a halt.

This article dives deep into the five most common CNC router controller issues, how to troubleshoot them effectively, and what you can do to prevent them in the future. Whether you're running a small shop or managing a high-volume production line, these insights will help keep your machine in top shape.

1. Controller Won’t Power On

You hit the switch—and nothing. No lights, no motion, no signs of life.

Why It Happens:

Blown fuses or breakers.

Loose or disconnected power cables.

Malfunctioning power supply unit (PSU).

Incorrect input voltage or surge damage.

How to Fix It:

Check and replace any blown fuses.

Make sure power cords are firmly connected and not frayed.

Test the PSU with a multimeter to verify correct output voltage.

Use a voltage regulator or surge protector to prevent future damage.

Pro Tip: Label your power supply connections clearly during setup. It makes troubleshooting faster and easier.

2. Freezing or Crashing During Jobs

Midway through a cut, your router suddenly locks up. Job ruined, material wasted.

Why It Happens:

Controller overheating due to poor airflow.

Bugs or incompatibility in the firmware/software.

Memory overload from excessive G-code complexity.

EMI (electromagnetic interference) or loose data connections.

How to Fix It:

Keep the controller clean and properly ventilated.

Ensure all software and firmware are updated to stable versions.

Break up large files into smaller toolpaths.

Use shielded cables and ensure proper grounding to eliminate EMI.

Maintenance Hack: Consider using CNC Control Retrofits that come with improved cooling and processing power to reduce these occurrences significantly.

3. Axis Movement Not Working

If your CNC router won’t move along the X, Y, or Z axis, you’re essentially grounded.

Why It Happens:

Stepper driver failure.

Motor or cable disconnects.

Faulty G-code or coordinate settings.

Loose or stripped motor couplings.

How to Fix It:

Double-check driver and motor connections.

Test drivers individually by swapping them between axes.

Inspect and fix any loose mechanical parts.

Review your CAM setup to ensure proper motion commands are being sent.

Upgrade Tip: If your machine frequently suffers from axis issues, consider CNC Control Retrofits that upgrade your stepper systems to more reliable and powerful servo motors.

4. Controller Doesn’t Connect to Computer

You plug in the USB cable and nothing happens—no connection, no control.

Why It Happens:

Outdated or missing drivers.

Cheap or damaged USB cables.

Wrong COM port selected in software.

Firmware and software version mismatch.

How to Fix It:

Install the correct drivers (often CH340 or FTDI).

Replace USB cable with a short, shielded one.

In your control software, manually select the correct COM port.

Verify the firmware on your controller is compatible with your software version.

Pro Note: Avoid USB hubs. Connect directly to your PC's port whenever possible.

5. Spindle Won’t Start or Has Speed Issues

Spindle problems can cause major setbacks—especially when cuts rely on consistent speeds.

Why It Happens:

No PWM or analog control signal.

Misconfigured spindle driver or VFD.

Incorrect G-code spindle commands (e.g., M3, S1000).

Motor overload or faulty wiring.

How to Fix It:

Ensure all spindle control wiring is secure and accurate.

Verify VFD settings align with your spindle motor specs.

Use test commands (M3 S1000, M5) to isolate the problem.

Test spindle motor directly to confirm it’s functional.

Expert Insight: CNC Control Retrofits often include improved spindle control systems, allowing for smoother and more reliable speed regulation across various materials.

Bonus: Preventing CNC Controller Problems

Fixing problems is good. Preventing them is better. Here’s how:

Regular Cleaning: Dust buildup is the silent killer of electronics.

Firmware Updates: Always run the most stable versions—not betas.

Cable Management: Keep power and signal wires separated.

Surge Protection: Always use voltage regulators or UPS systems.

Monthly Checklist: Schedule a 15-minute inspection every month to check connections, clean filters, and back up your machine settings.

Conclusion

CNC routers are amazing tools—but only when the controller is functioning flawlessly. Whether you're dealing with power issues, motion problems, or connectivity failures, the key is understanding what’s going wrong and how to fix it efficiently.

As we've seen, many common problems can be traced back to simple issues like loose wires or outdated software. But if you're constantly struggling with performance or compatibility, it's worth considering CNC Control Retrofits to upgrade aging systems with modern, more reliable hardware.

By applying the strategies in this guide, you'll not only be ready to fix issues quickly, but you'll also be in a strong position to prevent future downtime, maximize efficiency, and get the most out of your CNC investment.
