"Someone once said: Startups are run by engineers. Stagnating companies are run by accountants. And dying companies are run by lawyers."
Probably true.
Startups are run by biologists 👩🔬. 😜
Was this "someone" an engineer, an accountant or a lawyer? I'm asking because the statement seems to be designed to imply causation out of correlation. Looking at the nature of the channel, I would assume that by far, most viewers are engineers (or people with engineering interest), and the statement is read like "...are caused/created by..." But maybe good to be extra critical on the implied causation. That and: most startups never grow out to self-sustaining companies, stagnation is bound to occur at some point and dying is part of a natural cycle. (I'm not a lawyer, nor an accountant)
@@wim3565 I think you are reading way too much into what appears to be an off the cuff remark that someone made and I repeated here. Yes, most startups never see the full light of day, however, most successful startups that are interesting to the audience here are probably started by engineers. In terms of contemporary examples look to Intel and Boeing as engineering firms that were then run by accountants then look to a firm like Oracle that spends an awful lot of time in litigation. Or the zombie firms that acquire a lot of other peoples intellectual property that then spend 100% of their time in litigation while innovating nothing. I'm not an accountant and definitely not a Lawyer.
@@vincei4252 No worries. Just aiming for some healthy discourse.
As a person who likes to get things done, I've learned that looking for the underlying mindset/approach/process that causes a problem and working on that, gets better results than pinning it on the role or person that applies that mindset/approach/process.
That's basically what triggered me to react to your remark.
As to your examples: To my opinion, it's legislation rooted in (poor?) political decisions that opens the door for the zombie corporations and patent abuse that you mention. But politicians themselves are servant to campaign budgets, and next election's results. So again, not the person but the process.
In the end: Wherever there's opportunity, there's opportunists (Good or bad). Take away the opportunity, and...
Powerful introduction. It's a sad fact that everything you mentioned is so true.
Quite moving intro🙂
Agreed. Powerful because it is so insightful and brutally crystallises the frustration society feels. Indeed - what is the point in getting out of bed in the morning if all the day holds is to be stuffed into a cube desk in an office to perform some meaningless, ultimately non-productive task? Where your value is measured purely by spreadsheet wielding beancounters only concerned with maximising shareholder returns and the bonus payments to those at the very top of the pyramid.
It is not human, it is soulless or soul destroying servitude.
As a society we could be so very very much more but as always the few greedy sociopathic assholes fuck it up for everyone else.
Why do we put up with this again?
Everything comes to an end eventually civilisations die and are forotten. Initially it was the westerni idealogy of freedom and market drven forces vs communism and marxist philosophy. Well the latter has taken a massive hit and the former is now facing its demise. Covid was introduced to ensure new ideology would be easily implemented worldwide . This is an ongoing process but as we have seen people are easily manipulated and want to be told what to do.
Yeah, that description reminds me of the futile feeling during the Cold war. Every day was wondering if today was the day that some General convinced some leader that they could 'Win' WW3... And everything went to hell...
Yall take Care and be safe, John
@@chillybrit2334 - It's not so much the sociopathic assholes that fuck it up as it is everyone that fucks it up: most people follow their natural wants and needs, so society self-organizes. It's only the exceptional (good, bad, whatever) that change society (either for the good or the bad). Most people would rather have a steady income than go out and build a business.
Wow - that Makita looks brand new after your cleaning process.
Yeah, because it's an actual tool, not a PU impregnated toy, cooked up by puerile designers who haven't actually finished a proper design school.
That accent change when you came to know that the coffee grinder was made in Italy. !!
So, when are you going to rebuild the locomotive at the steel yard?
And then build a railway.
@@jfkesq I suspect your idea of 'not that difficult" is different to mine.
@@jfkesq perhaps not difficult but very expensive?
Setting up your own online shop might be an efficient way to find good new homes for all the stuff you fix and earn you some extra income along the way. With nearly half a million subs, you have a captive audience that would probably love owning a piece of equipment you lovingly saved from the scrapyard. A bit like a merch-store, just not with useless stickers and t-shirts, but quality-tools you gave a second life.
Very well said.
I second that.
The only issue with that is power grids are different in each nation and what works in Germany may not elsewhere.
Doesn't mean a repair curriculum can't be created. Said store doubling as a live education center as well as creating digital tutorials AND domestically selling tool sales could be very cool.
Or an ebay store so people could bid so everyone could have a chance to own it not just whoever got there first
30 minutes of pure scrapyard stuff? oh YES
I generally buy different things from scrapyards. Mostly steel, stainless steel and aluminium, mostly bar ends but I did manage to get 2 feet of 5" x 3" rectangular aluminium bar.
OH YEaaahhhhh
@@BensWorkshop That's a hell of a block of aluminum! I like big blocks of aluminum to use as a backer for welding. Copper is great but very hard to find (and expensive) in larger block sizes. Take Care and be safe, John
@@JohnDoe-pv2iu I do have a block of copper as well, but the aluminium is destined to become many things including a small diesel engine to power a 5" gauge train when I get to it. It did take me half an hour to cut off the block it came from with a metal cutting portable bandsaw though.
Lovely intro. Too true. Part of the solution may be recognizing the value of the small deeds, in others and ourselves.
funny seeing you here :D big fan
@@paalaasengstubbrud3524 Oh wow thank you so much! V10 Impreza build coming very soon to UA-cam. LOVE your profile image. I often use the FOX logo as a profile pic for forums and such. :D
@@802Garage Can't wait :)
808 Garage , And a large part of the solution would be to switch to being a Republican.
@@BruceNitroxpro Bruh what?
The world needs more people like you. I am not electronically smart but good mechanically. I been repairing and repurposing things for 4 decades.
"And once he had no reasons to live, he found at the bottom a new reason: Spite."
That "seemingly unreasonable amount of work" seems very reasonable to me. Love your videos.
If you're worried about your cutting disc shattering on start-up / when the fixture is still in the at-rest position - that's when the guard protects the operator the least - placing the switches on the left side could mitigate exposing your arm to any fragment's likely trajectory.
Being a DIY myself, I really enjoy your channel - and share a lot of your interests and philosophy
But your small prologues on the state of our world and times, are what makes your channel really special.
Your comments are spot on
I'm no electronics engineer but I've been using a foot operated switch from an old sewing machine for my angle grinder and it works just fine 😐
Great idea, I hate those grinder switches!
You need a backboard on the grinder stand to keep the sparks from flying all over the shop, they get everywhere, and apart from the mess, are a fire risk.
Then, face the backboard with plumbers torch flame felt pad guard. The sparks get "captured" in the fibers of the felt, so nearly ZERO sparks ricochette. (Make the felt pad 'moveable/reposition-able'. Why? The spark target spot on the felt, will get clogged up and wear away. Simply repostition the felt pad a bit, and voila! New spark target area!)
The 555 output being high is due to the timing cap being high, no significant load while the 555 is unpowered. Same situation with the single-side of Comparator, if you think about it. I typically install a low-voltage LED to ground on them, but a line-sensing Comparator output to that side of the capacitor in the 555 circuit would handle it easily. ;)
Indeed! One extra diode there would solve that issue. (Like a diode from the C to the - (or 0))
It's been a while since you posted this, but from a minimalistic point-of-view, if you used a small ~5v transformer and then simply added a diode + cap for rectification and then a resistor + cap + LED + MOC3061 all in series to that output you could tune it by adjusting the capacitor (perhaps the resistor a bit too) to do pretty much what you want here. The 2nd cap would charge up based on the RC and if you used a high-efficiency LED you could get away with little current (minimum the MOC3061 needs). I haven't spent any time penciling this out or anything, but it would require a very small number of parts and should discharge pretty quickly on turn-off.
Locally in BC Canada we are not allowed to sort through the scrap pile at the garbage dump. It's completely ridiculous that we cannot salvage, restore and reuse perfectly good items.
Sadly, the same here, in France.
Same here in the UK. We used to be able to take things but now the item is classed as belonging to the dump at the moment you take it out of your car, even if it is still in your hands! Absolutely disgraceful. But the hilarious thing is, they are putting up boards telling you how much the have recycled that week, while stopping you recycling.
Find a different scrap yard. Some let you go through the scrap some do not.
I love that you use the baby wipes, my father told me this trick, and it really is the best for grimy, oily nasty stuff, even use it to clean oven and it works like a charm! Apparently baby feces need the most aggressive cleaning agents known to man haha
" baby feces need the most aggressive cleaning agents known to man " ... or *woman* ;-)
Having had to wipe the backsides of my children... I can agree with this statement.
My only concern is that many of them were made from plastic fibre, I don't know if this is still the case. They were being put in the toilet as people thought they were paper, this was causing a huge problem downstream in the sewage system.
@@twotone3070 Yep still a very big problem
Your engineering knowledge is awesome and only matched by your consideration of the planet. It never ceases to amaze me how much stuff that can be fixed are just thrown away and discarded to the junk pile. Thank you for your incredible channel and never ever stop doing what you do. You are a true inspiration!
What a wonderful speech at the start. I can relate to what you are saying so much as an engineer working from home walking 10feet to my desk and living in a virtual unrewarding world. I seem to have to given up so of my life without any guarantee of health or happiness. I also find hope and happiness in some of the smaller victories of life like small repairs or interactions with people to make their lives better in some way. It's more rewarding than most jobs these days.
That fryer could’ve made an kick ass ultrasonic cleaner! You can buy the board and transducers cheaply on eBay and epoxy them to the bottom of the tanks. You can also add a PID temperature controller with a thermocouple to regulate the temperature of the existing heater.
4:56 a surprising way to remove permanent marker, is the draw over it with a whiteboard marker.
I've used this several times, the dry-wipe pens have an enzyme that stops it from setting, this enzyme also lifts permanent marker.
Sharpies work too - write over then wipe off while wet
@@rjamsbury1 interesting, I'll give that a try tomorrow.
The scissor step ladder is just to cool. I would of not let that go into recycling. The scrap guy I know would of sold the item to me at a lose just to see something cool saved from scrap. But they say one man's treasure is another man's trash. I respect your decisions and trust your judgement. Nice video Sir.
A hint about using cut-off wheels is always use the right flanges which should be 1/3 the diameter of the disc, if you use a grinder nut with a thin disc it can rupture it, grinder discs have a depressed centre with a small diameter nut that fits into it, but cut-off discs are flat and should have large flanges that match the backing flange.
I can only watch so many tool repair videos so you are the only channel that I use for this now that Ave has gone homesteading. I really like the way you explain circuits in a simple way that I can understand with my limited knowledge, it really helps me conceptualise and learn.
EevBlog just blows my mind and I switch off.
Whithout any doubt, you prove the value of repairing.
Man I’ve been waiting on new videos from you
Repairing old stuff in the search for the mean of life theme just blew my cap off once again😉
Hmmmm.... I really love your scrapyard adventures ! Recycling is under estimated these days, so nice to see you're making an effort to give things a second life.
i will never get tired of watching you fix stuff. I’ve had the same dream of running a “restored machinery” shop but i have doubts about its commercial viability, which is of course very sad.
I actually found your opening speech rather moving. Thank you for making this type of content. I hope you will continue with this series as long as you are active on UA-cam.
came here for the cutoff wheel mini chop saw and stayed because the introduction inflicted a massive existential crisis
WOW. Another awesome video. You are an amazing young man. I have learned so much from you in your videos. However, I am an OLD man and I forget a lot. I just wish I could have learned from someone like you when I was a young man. But that is in the past. Now, I wish you lived in America and could teach the young people here. You are so intelligent. My country could become better from your intelligence. I love your videos. Please keep making them. Great job young man!!!!
nothing is more relaxing than a German talking about tools.
i really love this series, and can't wait until the next installment. you're one of my favorite youtubers. when i was young, my grandfather told me to learn all i could, about everything there is so i would never be out of work. i think yours must have said something similar to you.
Mine told me to find a trade and I would always have a job!!
I was interested in vacuum tube electronics when I was 10 years old. My mother always bugged me to learn something other than "twisting wires." I eventually fell into telecommunications and made a living out of "twisting wires."
Along the way I learned carpentry, welding, auto mechanics and finally digital electronics and computers. I retired after 32 years of telecommunications and now teach Windows and Linux at the local community college.
I think I turned out pretty "well rounded" in skills as they say.
you really should screw a aluminum plate onto the wooden plate for the grinder support, also you should mount a spark catcher that leads into a whater bucket, that would reduce grinding dust and metall shavings a lot
Just be careful when you shower sparks all over that green cloth. You don't want to add fire to floods and pestilence, and the world needs people like you....
I believe you are RIGHT! focus on the small meaningful activities in life. This is our true source of happiness. Keep up the good work fellow scrap yard project finder.
Have you ever thought of starting a tool shop where people can buy refurbished tools?
I think it could do quite well 😉
Have YOU watched the video before commenting?
I feel envy for you. You go to the nearest scrapyard and find TOP QUALITY GERMAN MADE STUFF. No matter if not working since are so well done that just after a little twitching and bang!...are back to work like 60 years ago when new. Great content as always .
👍 Danke fürs Hochladen!
👍 Thanks for uploading!
👍 Very good and beautiful, thank you!
👍 Sehr gut und schön, danke!
Toller Kanal. Deine Einleitung hat soviel Wahrheit..... Leider. Danke für deine Arbeit. Macht viel Spaß zuzusehen...
I am jealous of the scrapyards in europe and the States, here in Canada metal recycling is such big business that the scrapyards are like black holes, things go in but don't come out. You can't even go in and buy stuff like this, like you can see dozens of table says junked for as simple as a broken cord
People should listen to the intro. It's very powerful and true. When you think there is no point just keep going. You can do it.
I really admire your drive and ability to “rehab” so many useful items. In the US, I have found a great use for stainless steel grills that have out lived their grilling lives and that is to convert them to rolling tool bases with a cabinet below. Easy to remove grill portion, fab a solid cabinet top and add a few shelves. Most homeowners are thrilled to have them hauled away as they have to be broken down to fit in a recycling bin.
Just found your channel. Wish we had someone like you working to do maintenance and repair on the equipment in our old forge shop. Mechanical presses, screw presses, upset (horizontal) forging machines and pneumatic hammer. US, German, and Japanese machines, we keep these old “cats and dogs” running, rebuilding them from cast offs other shops are ready to scrap. Difficult work and we struggle to repair, remanufacture and make new where replacements simply no longer exist and the companies that once built the original equipment are long gone.
Yes please, more scrapyard content.
There's a question I've been meaning to ask you for a while; most post-Apocalypse scenarios involve power grids going down permanently, or at least access to local grids being severely restricted. What's your plan for that? What will you use to generate the power to operate all these rejuvenated tools?
If I were you, I would have tried hauling that locomotive engine home! (giggles) I appreciate the circuit explanation, this will come in handy for many uses.
That intro is really great, I think you spoke to the inner thoughts of many, and gave others something to think on and consider. Meaning in little things keeps the burdens of life bearable. Keep up the good work my friend.
Designing circuits to accomplish what you want can be as complex as you like, or as simple as you like. So many ways to do the circuit to make what you want. Interesting circuit design with this one... Thumbs Up!
These videos are more than merely great. I feel like you are my long lost German brother, we have a very similar outlook. While pipe dreaming about where you may one day end up with that second hand shop keep New Zealand in the mix, you'd be one of the few people I'd be happy to share my workshop with.
one of the best things on UA-cam, this series
A day later and your words still in my head. Amazing how far a little education and willingness to work get you, and the sense of achievement from it. I tip my hat to you sir!
Fantastic intro. It's really only the answer to the absurdity of existence. To find our own meaning in life to keep us going.
Love that soft-start circuit. You can tell it's not Chinese because you're using a transformer for the low-voltage side rather than a capacitive dropper. I know how they work but they still give me the willies!
An added advantage to that grinder stand is that you could put a handle that extends to the left a ways. With your right hand on it you'd be out of the way of the disc if it even came apart.
Love your vids!! Although the electrical bit was out of my league I’m always glad to learn more.
Wow that angle grinder stand is a great and lucky find, as you say it's a rare piece. Seen plenty of DIY ones but that's something special.
Another good video. I have had those drill presses over the years they are really handy for many people who do not want a full scale drill press. The soft start was a nice touch.
I want to thank you for the intro to this video this perfectly sums up my feelings for this past summer as I'm about to finish my studies in agricultural field which seems to become impossible in the future at the hands of the Dutch government and the EU.
Your intro lets me see I’m not alone in my thoughts and shows me that it’s worth it to continue with my chosen path.
Thank you
I do really like your videos.
at 9:15 you need a part to fit on top of the coffee grinder. It would probably look like a funnel-shape and then you could put beans in without spraying them all over. Another great video! thumbs up!
Maybe he could forge something! :)
Simply amazing.
I've started repairing and re-purposing old hardware as well. Mainly thanks to you. Still, i'm not as lucky with spare parts, especially with the import taxes to Switzerland...
Anyway. Thank you so much for your invaluable knowledge and work.
as far as i know the power switch you use for the grinder is normally not to be used to switch loads its just used as a safety switch that can be locked in case of works. love what you do keep up the good work
Already the Intro is great - but the clever 'softstart from scratch' really got me!!
Pro-tip: if you need something that's not quite as hostile to your equipment to remove sharpie or stuck on dry erase marker, just use alcohol, most permanent markers use alcohol as the solivant to disperse the ink because it dries up quickly, but it can also be used on a rag to erase even the most stuck on of permanent markers by going the opposite way!
I love the value you are able to see in something others thought of as junk. I have always attempted to repair or repurpose anything possible in an effort to conserve its value and use.
Was not expecting to get hit with some heavy German philosophy at the top of this video.
Although my physical needs are being met, I'm having tons of mental/emotional pain, and I think you captured the sense of despair, meaninglessness, and futility very aptly.
"He who has a why to live and can bear almost any how."
--Nietzsche
That was a favorite quote of Victor Frankel. His book "Man's Search for Meaning" was pretty helpful, and is a quick read. I recommend it to people struggling with "What's the point of trying?". I believe people will find Frankel to be very compassionate towards that kind of problem, and has a deep and genuine desire to help people with it.
If you end up using that angle grinder in its holder much, I suggest you check the spec for that rotary switch.
Back when I did installation work, we only used those as what we called "work breakers". They were used to connect/disconnect the machine from the power source, but not to repeatedly turn the machines on/off.
There's a hole in the rotating assembly where a padlock can be inserted to keep the machine from being accidentally turned on while it's being serviced.
I'm not sure how well it will hold up to being used as a frequently used on/off switch.
Loved it - to be honest I never worry about the cost/value but just enjoy fixing/repurposing things. I recently repaired a 1950's Weston 505 analogue multimeter - a new digital one would have cost me $10 while the repair cost me $15 in parts BUT was a lot of fun and I have the meter as the end result.
I wish there was someone like you living near me who could educate me. I love repairing stuff, I work at a thrift store repairing bikes but my colleagues often bring me other stuff to fix bc they know I like that and I'm good at it. But working at a store where we repair/overhaul stuff for a second life would be a dream come true. I'm still looking to learn welding, hard soldering and electronics, but unfortunately my workplace is not very rich and somewhat understaffed so for now I'm just repairing bikes and tinkering on my own.
Thanks for showing us the difficulties on your way to a successful circuit.
I really appreciate your opening dialog, Its been very hard finding meaning in life lately. My best friend passed, I have to say I feel like I lost part of myself and now having to rebuild my life in many ways. Thanks man love the videos!
My instinct for the delay timer was to go straight to an Arduino and do a very simple program to turn on the output after a programmed delay (you still could have even used a trim pot with an analogue read to adjust the time without needing to reprogram it)
Arduino is a bit overkill but that's more in my toolset as well!
In the delay with a comparator, you can get rid of the second comparator by running a diode from your timing capacitor (anode here) to Vcc line (cathode there). At the moment of powering off the Vcc line will discharge faster because it has loads that drain it, and at some point voltage will be lower than the timing capacitor, then the diode turns on and transfers its charge to the Vcc line, thus, helping to discharge faster.
At the next power on, the Vcc line will get up in voltage faster than the timing capacitor and the diode will be kept blocked, not messing with the timing sequence.
I really enjoy your scrapyard trips. Thank you for making these good high quality tools useful again. You have made them even more useful with your specialized circuits. Thank you from USA.
Dude that grinder setup rocks! I love the locking mechanism for the work piece. Cheers.
I always enjoy your introductions, and totally agree with your philosophy. Greetings from Italy and keep up the good work!
Thank you for going into such clear detail about the soft start circuit. I watch your videos to be inspired, to relax, and to learn. Great job again!
I know it's really late to be commenting, however I've spent years with the 555 timer and think I have the solution to your short glitch issue when turning the grinder on: connecting pin 5 (Control voltage) to such a large capacitor means that there is a significant period that the internal reference voltage to compare against is shorted to ground, causing a delay before the capacitor charges up to a stable value. You need to use a much smaller value, maybe 100nF, so the charge time isn't so long. Hope this helps!
good job on that makita drill looks almost as good as new,its a bad world where good stuff just get thrown away. when as you have proved can easily be brought back to life and almost as good as new
I applaud your introduction - perfect!
All your video's are good, but I especially liked this one.The opening monolugue was great and resonates in times like these. Thanks for all the effort you put into these episodes.
Nice job as always. Please keep these salvage yard finds coming. Very interesting and informative!!! Thanks for your efforts.
I just came across this channel this evening. As a person who likes (loves) to restore things, in my case guns, bows, motorcycles, cars, etc., this channel is what I enjoy most! Thanks for the awesome videos you share. God bless. Rev. D.
Another facinating video Gerolf. Perhaps a worthwhile addition to the angle grinder chop saw would be a retracting saftey guard as found on most wood working chop saws, something to look out for on your next scrap yard visit.perhaps. Best wishes from Wales.
Yes AEG is a shadow of what it was. I had an AEG Lavamat electronic, that eventually I scrapped, because I needed to get new bearings for the drum, and the spider, which were more in cost than the machine that replaced it, just as parts. Still have a nice AEG electric drill, which is over 30 years old, and still in running order.
Soft start I have built a few over the years, the first was for a light box, that used 40 40W golf ball lamps in a B22 base, which would trip the 30A mains breaker on every second turn on. Built a triac controlled start using a unijunction transistor to slowly ramp up the power to full, which solved the problem. Another for a large variable voltage transformer, like yours, as it has a DC resistance of 0R5, which led to a massive turn on surge. Relay and a 1 second time delay to short a 10R 40W resistor bank, with a 130C thermal fuse on the resistors just as safety, and it has been in use for a long time. No electronics, just a resistive divider, bridge rectifier and a 470 uF 100V capacitor, driving a repurposed 48VDC relay.
Also used the one tapping, 60VAC, with a rectifier and voltage reference, to build a suppressed zero output voltage monitor, so I could get a better reading of the output on the analogue meter I had for it, using the existing scale to allow reading voltage from 60VAC to 360VAC, though it only will do 330VAC with a 240VAC input, but at least the scale is a lot easier to read. Checked calibration on the output, and it agrees within reading error all the way. 230VAC incandescent lamps will run up to 330VAC no problem, provided you run them up slowly so they can heat up, and a 40W lamp is as bright as a 200W one, though lifetime can be measured in minutes there, they turn into photoflood lamps. This was all built using nothing bought new, only stuff already there, either old stock or salvaged parts.
A meaningful and heartfelt introduction to this video. Thank you.
You can create a simper soft-starter by pulsing a full-bridge rectifier. Connect an AC load in series with said rectifier, and when you short the DC leads of the rectifier with a transistor, AC flows. PWM the DC leads' short, and you get a dimmer. 555-timer for PWM and timing, rectifier, power transistor, bypass relay, that's not complicated and takes little space.
Watching has gotten me longing for a visit to my local scrapyard. I've made friends with the workers there and am able to "work deals" for the things I find that I want to give a better home to. It hurts me when I find I've made it there too late and they have crushed items that were perfectly useful and/or hard to find. I think of all the resources, design, labor, etc that went into making such items. Then, in one mindless action, they are destroyed. Things that I would otherwise not be able to afford... At least the materials will be reused.
Making is necessity, and making is also an art. When we stop making we lose something vital. We can’t call be lawyers we need makers - framers, plumbers, electricians, product designers, and the millions of jobs that support these. Sustainability means making it yourself, whether it’s energy, or a product.
My wife has a family member with access to scrap and picks up some great finds. It's hard for general members of the public to get stuff.
You should make an episode entirely of you rummaging around the scrapyard looking at all the goodies to be found.
I'm glad to see some electronics in the videos..... I've been using one of your relay/555 inrush limiters on my power supply for a few years.... I'll have to try out the new version too.... and I LOVE the spoken intros to these videos.
On your electronics bench... I get distracted by that big blue plastic solder sucker.... I've got one of those and it quite literally changed my life.... in England it's now got harder to buy things from Germany so I'm really glad I got it when I did.
I love your idea to open a shop.... one of my own dreams.
APPLAUSE!
Excellent opening monolog.
Great engineering, as usual.
I need to visit my scrapyards.
About that coffee grinder, you will have to change the capacitor, these motors require a good cap to start, especially when you grind espresso and it forms a "cake" in the grinding wheels between grinding sessions. From a barista who changed his Nuova Simonelli grinder's capacitor lately :)
Ein tip vom Tischler fuer den roten not knopf: Es ist von Vorteil den Schalter in kniehöhe anzubringen wenn man nachruestet. Solltest du mal wirklich einen Notfall haben und kannst nicht mit Händen danach greifen, hast du immer och die Möglichkeit mit dem Knie auszulösen! 😉
super Idee, Klasse!
Your transient voltage should be controlled by a coil. Honestly I know this from college, but that was 40 years ago and I dont remember the math at all. What happens is the that voltage starts on the ac curve and is present much like DC, so the current can be slowed or stopped by the coil, but once it is fully energized it will operate as a short in ac circuit. For some strange reason watching this made it all come back!
while I love building my own circuits, you can also keep your eyes open in the junk yard for a time - delay relay, usually it looks like a standard socket with a knob on it, fun and nice video either way :)
Drought, fires, flooding and tornadoes. We've had all 4 in the space of 18 months here in regional Australia.
I’m in the process of refurbishment of a drill press just like that. I’ve had it for 20+yrs & never used it. Bought a used 1/2" drill today so I figured I might use the drill press .
