Thank you for taking the time to make videos and show us this, do not stop!
Hey, FORTH! Nice. You don't see much of that these days.
I've been thinkin' about throwing it onto an AVR and playing around with it again. Well, either that or one of those microLISPs.
I notice you got a nice array of informational videos. They look interesting - I'll check some more of 'em out.
You really have some great ideas and it's nice that you are sharing such money-making ideas. I was a tech before I became an engineer but never liked fixing broken equipment. Still, in a pinch, I have done it when I had to. One thing I learned was that fixing gear that was working is quite different from making a new design work. If a device was working but isn't now, it is very likely that only one thing is wrong with it. A new design, however, could have many faults; wrong design, not assembled correctly, etc.
Good stuff here. I liked your approach to making a universal controller. Might be a marketable idea.
Yes .. you have some valid points. The best scenario is to repair to factory spec by finding the faulty component. When designing a new board, keeping all safety features intact is a must. In those cases a PCB was built and tested intensively.
Most of those designs were interfacing new logic family IC's to older obsolete logic families on the original board.
I did run across some business owners who needed their machine up and running or their business would suffer drastically.
It was good that I could help them out.
In the UK you would most likely need an NICE certification and even on the jobs you didn't the liability would be worryingly high, smells like come-back for young players. All that said: I really liked your build and dug the diag mode button :)
Very helpful really appreciate the advice
There's money in consumer electronics if you know where to look. Do some research on Eurorack synthesizer modules. Most synthesizer modules sell for hundreds of dollars. They are essentially select components of a synthesizer coupled via phono-jacks, not a full synth. You can go as far down the rabbit-hole as you like. You can put together a simple synthesizer module from a kit and sell it. You can buy a circuit board and face-plate... use an automated BOM to search a few of the big parts shops... sell those for even more. If you want to design your own modules... and even program your own arduino code into them.
Some keywords to search for examples would be "Befaco Eurorack" "Westlicht Performer" "Ornaments And Crime" "Doepfer Eurorack" "Mutable Instruments clones", etc. A resource library for modules and those that can be built by a kit would be www.modulargrid.com
"Thank GOD", thank you very much for your support and time 😉 How do you design a universal controller 🤔
Very underrated channel. Thank you so much
You're welcome. Thanks for the feedback.
I've used ULN's before, but always as an output. I had never thought of using them as an input driver until you mentioned it. Sometimes just a little bit of "out of box" thinking can make a big difference in solving a problem!
Yes as an input device they make good voltage converters with a wide range of input voltages to open collector output to drive 3.3v or 5.0v microcontroller GPIO. Thanks for sharing.
what percentage of the equipment's price would you make for repairing it?
Hi, thanks for this amazing video! I would absolutely love to be able to do this kind of work on the side to supplement my family income. I have a bit of beginner knowledge, I build systems for testing components as my day job I use Arduino and python. Aside from the book you recommended, is there a learning path you recommend to get to this level of competency?
Thank you for the insight
You're welcome!
yes but i know little about electronics and can not create anew thing but i want to make some earning to run my home
I want to open a rs type store slash cafe for makers and maker space with some workers with the knowledge and passion for inventing and electronic engineering.
i think the best way is to buy cheap broken devices, repair them and resell them
So about how much money are you making do this? Is it beer money or quit your day job money?
You really deserve a like and a subscribe
1) How do you determine your fee like with that $20,000 machine you fixed? 2) How do you CYA with liability insurance? 3) what is the minimum electronics knowledge to make repairs like you did in your video..?
do you happen to sign a contract with your customers that cover your if the circuits cause safety issue? Like use at own risk or something like that.
How to I make that board?
The problem with the meatgrinder is it's been wrired up wrong ;)
what if you fail or realize you won't be able to make the repair or realize it is too complicated and not worth you time? i.e. How do you manage liability issues? Do you make a contract or is it by word of mouth and honor system?
I think that's what an LLC is for.
Do you add the DIN rail connectors and terminal strips to the box or do you buy them that way?
I add them to the box enclosure. They are available online: www.dipmicro.com/store/DIN-BRACKET-PAIR
Excelent vídeo! What platform did you use to write the bluetooth app , and what is the bluetooth module that you used? Thank you for the info
The program was written in Forth and the BT module is the HC-06. Check other videos on my channel for more information.
@@0033mer thank u a lot
Thank You
You have me interested in this type of work please let me know what I can do to get involved . Thanks for the heads up.
Start out by going to Equipment auctions to see what equipment is out there and talk to the buyers.
Here is a list of equipment I was involved in:
Electronic signs, scoreboards
Battery chargers for golf carts and forklifts and golf cart motor controllers
Railway track maintenance equipment.
Industrial food machines and controllers
Welder control boards and refrigeration control board for semi trucks and rail cars
The common theme to all these items is that they work in harsh environments and are prone to failure.
Check out this website. This guy who I dealt with started out back in 1970 just repairing battery chargers and is still around today.
Have a look what he is doing today. Good luck in your ventures.

Nice enclosure! How are they called and where can I buy them? Searched a while but can't find it
The enclosure is made by Hammond Manufacturing.

0033mer thanks! You really deserve more subscribers, very good content!
Thanks for the feedback.
thank you bro
You're welcome!
Excellent video. Very few other electronics channels are covering industrial work or anything more than just replacing components.
In part one you recommended a couple books for learning. But I've found that books tend to be too basic or too specialized. Would you recommend any online courses?
The books I mentioned are very good and thoroughly get into many subjects. To keep up with the latest trends and technology try a " Circuit Cellar" magazine subscription where there are detailed instructions on project building and theory. The best course you can get is "doing", where all the learning happens.
You Sir, make EXCELLENT videos! No long prattling on with useless info! Quick, precise edits with all useful info!
By any chance do you watch/subscribe to AvE ? he is a bit ( ahem) more irreverent than you, but he is the "funny and informative" to your "extremely informative". I would love to see you two get together and do magic...
If you two do work together, I would like lots of free t-shirts, XXL please LOL.
And DAMN, PLEASE make many MORE videos. You have a gift. Thanks for sharing it...
Thanks for the feedback.
"They think it's black magic." LOL
👌🏼👌🏼👏🏼👏🏼👏🏼👏🏼
Using Forth - wow
👍👍👍👍👏👏👏👏
can you share schematic ?
The schematic is basically the same as in this video: ua-cam.com/video/vPSwkDBcUJQ/v-deo.html
Instead of the GPIO lines driving LEDs, they drive the ULN2803 IC.
actually i want to get idea of your power supply which is converting 12 to 5v , what values of filter capacitor are you using ?
.47uf on input of regulator and .1uf on output.
The only problem is that hobbyists do lack experience doing diagnostics.
With decades of experience under my belt, I personally know this can't be "wished away", no matter how naive one is.
Liability, liability, liability, and when you're not looking.... liability. Sell a $400 custom PCB, get the $4,000,000 lawsuit for free when somebody loses a hand in the meat grinder.
Take risks, but not in a naive way. The grinder was sold many years ago and is used every day. It has a electronic and mechanical interlock on the door before it can be started, so no lost hands.
