I am a retired tinkerer. I have tinkered with electrical and mechanical things my entire life. My parents tell me I used to take all my toys apart to see what made them work even when I was quite young. I foolishly nearly blew my head off with a homemade hydrogen generator at the age of 13. I made it and it worked (too well). The container I was collecting the hydrogen in exploded and I was banned from experimenting for a while. A classmate and I designed and built a gasoline and oxygen... Read More »

  • 5 Simple Ways to Determine LED Polarity

    The first led's I owned, I cut all the leads to the same length because of my obsessive compulsion problem ( to me they had to all look the same)! Any way that made it more difficult when I went use them in circuits. I used the large anvil as the negative way. It is funny now, but when you are just learning you can do stupid things like touching your soldering iron tip to see if it is hot. ( I still can't believe I was that stupid, but I did it more than once). But Electronics and making circuit boards is my favorite hobby. Some of the new parts I cannot use mainly because they are so tiny I lose most of them. I can solder them using a magnifier if I can just keep them out of the carpet long enough to tie them down.

  • How to Make a Touch Switch Using One Mosfet

    Why are all the crybabies wanting a drawing in their choice of format. They have to have everything their way. Heck, everyone does not march to your particular drummer. As the Eagles sang, "Get Over It". The world does not revolve around your likes and dislikes. The drawing is perfectly adequate to convey a simple concept. The author was not trying to show you how to wire computer. You haters make me sick, as I am sure it does others. Excuse me while I go toss my lunch.

  • How to Integrate Wires Into 3D-Prints to Build a 18650 Battery Charger

    I am just wondering what regulates your solar input to the 5 volts expected by the TP4056. The specs give some leeway, (4.35 - 6 V, 5 V recommended) but direct solar connections can vary quite a bit. I suppose if it works, it works but you could be shortening the life of the TP4056 and possibly your batteries if you have wide voltage swings. Just my conservative opinion. I like to stay as closely to specs as possible.

    Motion Detection Lights

    Lots of comments about the dangers of line voltage and they should never be ignored. The safest way to "play and learn" is to get a wall wart step down transformer that isolates the line voltage from the user. Duh, a battery is actually the safest way, so we can all speak too fast. The major point to take from all these comments is DO NOT MESS WITH LINE VOLTAGE. You will be exposing yourself to all the voltage and current supplied to your house, at least the branch circuit you are plugged into, and that will kill you in a heartbeat by stopping your heartbeat, and frying you. I lost a neighbor who was fixing his own well pump and accidentally touched a 220 volt main, he died instantly. Electronics is a great hobby, but please be safe.

When I was in training to be an Air Conditioning mechanic, I was taught to keep one hand in my pocket, if the unit was powered up. That way the current would not have a path through your arms (and through your heart). It really is that dangerous. Nuff said, I will go back to sleep.

  • 3D Printer Part Recycling Grinder

    I can see you got tired, calling the files such names. Questioning the marital status of their parents. Tired old joke, sorry. Great instructable. You show how people can do things with few other tools if they use their best tool, their brain. In my childhood I spent quite a few hours in a blacksmith's workshop. It was amazing what he could do with just heat, lots of muscle, a hammer, and his brain full of knowledge. If you live near a junk yard, an old washing machine motor, geared down with appropriate pulleys and a drive belt would make your grinder rip through plastics. The motors are incredibly strong when geared to slow the speed down. It is probably already in the works, but I also suggest a hopper of some if only as a safety barrier. If your finger gets snagged on a ra...

If your finger gets snagged on a ragged piece of plastic, in it goes. My next door neighbor cut off two fingers trying to pull a ragged piece of plastic from underneath a running lawnmower.

    That should have read "a hopper of some kind." Apparently, I am not using my brain or my eyes, or both.

  • How To Cleanly Remove Blackheads Painlessly!

    My name is from breadboarding electronic experiments which I have played with for about 53 years. You can guess the old man part, that white hair is not dye. As for the use of the word "hung" in the context I used, that was a saying of my grandfather's and sometimes here in the rural south, especially a couple of generations back, local use of English was completely different from standard dialect. In fact, I knew one old gentleman who used to say he "ruck" leaves from his yard, and "clim" up the stairs. Instead of thank you, a lot of my elderly neighbors would say, "Much obliged". As a kid that always struck me as funny. As a radio comedian once said, " I don't know if I saw it or I seen it is correct, so I will say "I became awa...

  • Splitting Water the Easy Way

    Almost everyone has an intuitive feeling about how explosive gasoline is, but they never stop to consider that hydrogen can power an automobile just as effectively. We know from experience that hydrogen is not a toy just like gasoline, propane, or natural gas. I am just glad neither of us got seriously injured in the pursuit of science.

    That is too bad. I suppose I should mention the 4th of July when I was around 10. I took apart very many firecrackers and put the powder into one big honking homemade rolled paper "experiment". Due to my stupidity, I used one of the regular fuses for the thing. I put a match to it and before I could run, it exploded with far more power than I was expecting. It cracked the corner of the concrete deck it was sitting on, burned some of my hair off, and I couldn't hear well for days, except for an incessant ringing which I heard quite well. That day I had a box of 144 Silver Salutes which were legal in the early 1960's. I am glad I didn't try to make anything with them. A young man in our area was killed when he tried to toss one out a car window, it bounced back into the ...

A young man in our area was killed when he tried to toss one out a car window, it bounced back into the car, landed in the box which still had 143 in it. They all exploded with the force of a few sticks of dynamite and ripped him apart.

  • Splitting Water the Easy Way

    Be careful with the hydrogen, especially if you collect any quantity at all. It is very, very explosive. I tried an experiment at the kitchen table when I was 13 (over a half century ago) but anyway I created a one pint glass jar full of hydrogen and one spark caused quite an explosion. I won't reveal how I did it because it works too well for the inexperienced young scientist!! In my youthful, blissful ignorance I wanted to see if it would burn to prove to myself it was really hydrogen as I had no other way to test for it. Blew the glass jar (not the smartest collection vessel but I had an old mayonnaise jar so I used it) all over the kitchen, frightened my mom half to death and got my tinkering around banned for quite a while.

  • How To Cleanly Remove Blackheads Painlessly!

    Great instructable! The naysayers always amaze me with their negativity but as my grandad would say, "Some people would complain if you hung them with a brand new rope". They don't even stop to think that you are trying to help them with an all too common embarrassment for teenagers and other ages also. No one else may notice, but you feel like everyone is looking at the blackheads and just want them gone. When you are young the mirror shows imperfections probably only you notice. When you get my age, the mirror shows what everyone sees, a wrinkled old man. Smiling makes wrinkles much harder to see so you gripers, shut up and smile. Life must really stink if all you can do is try to bring other people down.

  • DIY-Solar Energy USB Phone/Tablet Charger

    Great idea. Is there any particular reason for not putting the diode on the circuit board (at the other end of the positive wire)? I can understand the need for protection against reverse polarity. Perhaps you placed it on the solar cell to protect it no matter what gets hooked on the other end of the wire, like if you decided to reuse the cell for another project. I know how experimentation works, it is always a "work in progress" as our minds come up with new ideas. Thanks for showing everyone how easy it is to convert the sunlight to usable electricity. Lots of people don't understand the need for regulation of the solar cell output and therefore burn things up and quit experimenting.

  • Make 4 Useful Things From 9V Dead Battery

    Yep, I have been working with capacitors today and the uF transformed in my brain to uA, you are perfectly correct, I should have said milliamps. I was checking out this instructable while I stopped work on the project for a rest. I just wondered about the 0.5 watt leds as that is a very large power rating for any normal leds and I found conflicting information on the sellers page. I hurried to comment before people ordered some and got less than they expected. These leds would need a 290-300 ohm resistor for operation at their max ohm rating, and would not be nearly as bright as a true .5 watt.

    Read all the details on the Amazon website regarding the strawhat leds. The leds from Amazon are listed as 150 watt beside the picture but click "see more product details" and you will find in the additional details are listed as 0.06 watt and use 3.0--3.2v at 20 uA. A 100 ohm resistor at 3.2 volts would give 60uA current from a 9v battery. This is 3 times the rated limit and will surely burn out the diode, who knows how fast, but it will do it. They can tolerate some over abuse but it greatly shortens the lifespan even if they don't immediately die on you. If I had purchased these, I would let Amazon know that the seller has posted false and misleading information up front and hiding the real details in the fine print and I would want my money back. 0.06 watts is a he...

Off by a factor of almost 10.

    You Pb us down the wrong path with the Argon joke. I hurt myself when I put my Neon a Copper's car. He put the Iron's on me but as an Native American Indium might say, "Me hope it Helium soon." Gosh that is bad, but it is early.

  • How to Interface Stepper Motor With Arduino and Stepper Motor Driver

    The Arduino website reference page states that the maximum voltage to be applied to the Vin pin is 20 volts, but the recommended maximum is listed as 12 volts. Therefore, 35 volts will more than likely fry your Arduino or burn out the voltage regulator circuit. Good idea though to teach others how to attach a stepper to the Arduino. I find that a lot of people are completely in the dark when it comes to step motors. The step motor simply will not run if you attach voltage to two wires like other small motors, so many people just leave them alone. They are missing a lot of great uses for steppers so perhaps your tutorial will help some fellow enthusiasts to learn to use step motors. Kudos to you.
