A lot of people are asking for the right to repair. Many people believe products should last longer, and therefore when broken, they should be repaired. This requires products to be designed for repair as well as support for repairers of all kinds. The goal of right-to-repair rules, advocates say, is to require companies to make their parts, tools and information available to consumers and repair shops in order to keep devices from ending up in the scrap heap. The surge in interest in right to repair is good news for consumers and environment, but it isn’t great news for those companies keen on planned obsolescence.
Fix, or Toss? The ‘Right to Repair’ Movement Gains Ground article says that in USA both Republicans and Democrats are pursuing laws to make it easier for people to fix cellphones, cars, even hospital ventilators. In Europe, the movement is further along.
Vice article The Right to Repair Movement Is Poised to Explode in 2021 article says that in USA fourteen states are exploring “right to repair” legislation as the movement gains steam. Whether it’s John Deere’s efforts to make tractor repair costly and annoying, Apple’s bullying of independent repair shops, or Sony and Microsoft’s attempt to monopolize game console repair, US corporations have done an incredible job the last few years driving bipartisan public interest in the “right to repair” movement. Last year witnessed monumental progress for right to repair and 2021 is expected to take the effort to an entirely new level.
In addition to the environmental impact of slowing the rate of expanding landfills there are also other benefits. A recent report by US PIRG found that repair monopolization comes with significant costs for American consumers. It also found that American families would save $40 billion ($330 per family) per year if they repaired more products and used them for longer periods. That’s of course
The French repair index: challenges and opportunities article tells that since January 1st 2021, France is the first country in Europe to have implemented a repairability index on 5 categories of electronic devices. While this index is a key milestone for the Right to Repair in Europe, it isn’t without limitations.

This Hack is Genius! Fix Broken Plastics With Plastic Welding Method
https://www.youtube.com/watch?v=x4T3KcMJNYE
Many items in the house and workshop are made of plastic. These plastics stretch and break over time, and most people throw away their broken plastic items. However, since plastic is a material that melts easily, you can easily repair it with plastic welding or soldering. If you have broken plastic items and you want to throw them away, be sure to watch this video called Repair your broken plastics with plastic welding method and learn how to repair your broken, cracked plastics.
Viewer comments:
I have always had a SNEAKING suspicion that plastic could be easily melted together like this but never really tried or investigated, this is brilliant!
You can buy a kit to do this from most autobody/collision repair suppliers, it also comes with different types of plastic rods for different plastics
we were actually having a hard time getting decent strength from the welds bet that mesh method makes it work perfect
Also, SUPER IMPORTANT, those fumes are incredibly toxic, wear a respirator if your going to do this.
Tried the first method (with a zip tie) on a plastic piece that had broken off of one of our refrigerator drawers…and it was a sizable piece that was part of one of the sides that rode along the groove to hold the drawer in place, so it had to be a strong weld. And it worked, thank you!

Clean the area.
Drill holes at each end of the crack to prevent it from spreading.
Melt a plastic rod onto the crack.
Reinforce the plastic weld with steel mesh.
Add more plastic on top of the mesh.
Smooth it out.
How to Fix Cracks in Plastic Using a Hot Stapler
https://www.youtube.com/watch?v=dGveuYxwzg0
This technique doesn’t fuse the plastic together like #PlasticWelding would, instead, it uses metal staples to link the 2 pieces of plastic together.
To achieve penetration into the plastic, the tool uses electrical current to heat the Stainless Steel elements (this is why they’re referred to as Hot Staples) which allows them to be pressed into the plastic.
By linking both pieces of plastic together, movement is eliminated. This increases the plastic’s structural integrity, and prevents the crack from spreading further.
Combined with plastic welding, you could hypothetically achieve a fix that’s stronger than the original plastic itself.

HOW TO FIX A MULTIMETER THAT DOES NOT WORK (MY TOP 3 PROBLEMS & REPAIRS)
https://www.youtube.com/watch?v=zBXfmXwBsww
In this video we look at common issues with multimeters.
Tomi Engdahl says:
Unobtainium is often not the problem when restoring equipment. Bigger problems are Understandingum and Appropriatum.
A transistor for instance is a transistor and most are very generic. So if you are aware of a few facts then there are thousands of potential substitutes.
Tomi Engdahl says:
I’m finding that it’s often not unobtanium, but howmuchareyouwillingtospendium.
Notworthicus timeium.
You are spot on… For most audio applications many transistors may be used to substitute.. However, there are many transistors mostly for specialized applications… Switching Power, avalanche, RF applications, noise..ect..
Not so much in test equipment, but many older radios use ICs that have not been manufactured for over 40 years. Not that they couldn’t be substituted for by a clever circuit, but the development time and cost could make the whole endeavor fruitless.
The worst situation is the dreaded “die spin” where the manufacturer improves a chip and this breaks the product you’re building.
The original 2N3055s were silicon junction transistor. The current ones use Mesa or similar fabrication techniques. The older 3055s have an Ft of around 400KHz, the later ones 4MHz. Back in the early 1970s, I built a CDI (capacitor discharge ignition) unit for my vehicle. It used a pair of 3055s in a self oscillation inverter based on a 12 – 0 – 12V secondary mains transformer. The capacitor charged up to 400V DC via the coil’s primary. It was discharged by shorting the DC output of the inverter with an SCR. The inverter would shut down when shorted and restart as soon as the SCR turned off. With the later style 3055s, the inverter would change from oscillating at around 10KHz to oscillating at around 100KHz. The SCR never turned off. Also the later 3055s, having a smaller die, and much less thermal inertia, tend to fail more easily on overload.
Thinking like this is a big threat to people who want to have reasons why they can’t fix the stuff they have. Perfectionism is a perfect hedge.
As long as you haven’t broken your back from all the Heavium
It took me many years to learn that. In my defense, transistors were probably a lot more non-generic in the 60′s when I started playing around. Some germaniums were still around. Low frequency cutoffs or low hfe’s on Ge and Si. After the time about the 2N2222 and the celebrity 2N3055 became ubiquitous and cheap(and they were really useful a lot of places), I gradually realized that I could relax my perceived requirements for most exact replacements. PNP and NPN. Cory Lytle notes some issues with FET’s and diodes that I think are correct. If you can look at data sheets and do a little bit of examining the differences, you can guess right most of the time if your potential replacement is viable.

Protect Vintage Gear With Easy Capacitor Reforming
https://hackaday.com/2023/06/05/protect-vintage-gear-with-easy-capacitor-reforming/
Having acquired some piece of old electronic equipment, be it a computer, radio, or some test gear, the temptation is there to plug it in as soon as you’ve lugged it into the ‘shop. Don’t be so hasty. Those power supplies and analog circuits often have a number of old aluminium electrolytic capacitors of unknown condition, and bad things can happen if they suddenly get powered back up again. After a visual inspection, to remove and replace any with obvious signs of leakage and corrosion, those remaining may still not be up to their job, with the oxide layers damaged over time when sat idle, they can exhibit lower than spec capacitance, voltage rating or even be a dead short circuit. [TechTangents] presents for us a guide to detecting and reforming these suspect capacitors to hopefully bring them, safely, back to service once more.
Capacitor failure modes are plentiful
When manufactured, the capacitors are slowly brought up to operating voltage, before final encapsulation, which allows the thin oxide layer to form on the anode contact plate, this is an electrically driven chemical process whereby a portion of the electrolyte is decomposed to provide the needed oxygen ions. When operating normally, with a DC bias applied to the plates, this oxidation process — referred to as ‘self-healing’ — continues slowly, maintaining the integrity of the oxide film, and slowly consuming the electrolyte, which will eventually run dry and be unable to sustain the insulating oxide layer.

Capacitor Reforming – Why Do Capacitors Need Reforming? | Ask Al presented by Quad Plus
https://www.youtube.com/watch?v=OW3703sUD5E
Many AC and other inverter type (i.e. solar) drives contain aluminum electrolytic capacitors for DC bus filtering. If these capacitors have been in storage for a period of time, for example as a spare, they may explode if reforming is not performed before applying full power. Al explains the capacitor mechanics and how you can prevent explosions.

Topic: Meter movement sticking.
https://www.eevblog.com/forum/repair/meter-movement-sticking/
If an analog meter is sticking, it isn’t in good shape. If it moves closer to the correct position when you tap it, assuming there is no obvious foreign object in the mechanism or bent pointer, either there is dirt in the bearings, or they have been damaged by excessive mechanical shock. Cleaning the bearings is only an option for an experienced watchmaker or precision mechanical instrument technician. Lubricating the mechanism is absolutely *NOT* recommended as it will attract dirt and further gum it up and may react adversely with glues and lacquers used in its construction.
The only easily rectifiable problem is if the pointer is being attracted by a static charge on the front cover glass or plastic. Assuming it can be removed, cleaning both sides of it with an antistatic lens cleaner so a trace static dissipative film is left on the surface will remove existing charge and reduce the risk of new charge buildup.
If the needle is not interfering with the meter panel and the hair spring is free moving and not damaged. Then a tap easily returns the meter to either zero or to the correct reading, then it’s likely a contact point at the top or bottom shaft bearing points (the supports for the shaft). Either it’s worn or dirty.
To clean these I would apply a dab of contact cleaner or IPA something that will loosen dirt then manually work the needle over it’s range and let the hair spring return it, repeating cleaning and moving several times if it still sticks. If you are going to lubricate, it would be the lightest of oils wiped dry to a minuscule amount. You might find though no lubrication is required as there may be enough residual lubrication left after cleaning, that is if it was even done in the first place.
Tomi Engdahl says:
The most common reason for a meter sticking is the presence of some fine metal flakes in the magnetic poles and the moving coil. Removing them can be a challenge. The “old pro” method is to use a cotton Q-Tip. Pull the end threads out to make a fine string-like extension. Get the end in the gap around the coil and try to “sweep up” any flakes you can see. The cotton is soft enough to not bend anything, but can grab fine metal flakes.
