    OLED I2c Display With Arduino

    For those with the yellow top and blue bottom, these are OLED'S there are no real leds on them, the yellow is actually a piece of yellow tape placed on the screen to show the yellow content. They were designed for some cheap MP3 player or something that had a menu up there, of course nobody really want's MP3 players any more so the screens are easier to peddle then the players.

    Tried the code with the distance sensor, works good as well, I just happend to have some of those laying around in a parts bin. I am not sure what I was going to do with them when I ordered them several years ago, I think some sort of ghost sensor for my niece who is a paranormal nut case and goes hunting ghosts all the time.

  • Rechargeable LED Flashlight Using PVC Pipe

    Cool build, I love home built designs, and yours is good. I have tried my hand at several lights. Had one of those old two six volt lanterns with florescent bulb, the thing died but left a fantastic base for a large LED light. I installed two 3 watt light bulbs on the face where the tube used to be, powered each with 3 18650's and ran the power switch through the built in switch, makes a great light and after one year of occasional use, I have yet to have to recharge the cells. Another was built using a 4 watt light mounted in a sort of jeep design, I attached it to a large project box and stuck 4 18650's in it, added a volt/amp meter and put on banana plug jacks for the tester as well as a plug so I could disconnect the light and use the 12 volts that I push to the light through a po...

  • Mini Fridge for a Camper Van or Desktop!

    Looks very cool indeed. I had planned on building one for our water bottles in our motor home when we are on the road, save opening the fridge when on gas, but while I was awaiting some parts from China, the wife drug me to a garage sale, and I found a nice 12 volt system for twenty bucks, could not pass that one up, and it does a wonderful job on both 12 and 120 volts in our rig. We winter in Arizona so cool water is a must even in the winter time.

    DIY Kiridashi Knives

    I tried my hand at making a few knives when I was in my gunsmithing phase of my life, a couple turned out passable, one with real stag handles and one using walnut from an old gunstock. For steel, I used old files that had passed their use by date and no longer filed as well as they should have. It was great fun but when my blasted belt sander broke free from it's stand, and I did the natural thing and tried to grab a running belt sander to keep it from crashing into the floor. Man what a mess my right hand was; really messed up my day and put an end to my knife building days.

  • Change 9 Volts to 5 Volts

    Hi, thanks, I needed just that, a small 5 volt power supply to run a little arduino count down timer off a 9 volt battery. Wife needed one for her eye drops to take care of her glucoma, she needs to time the drops for 2.5 minutes after insertion, she has been squinting at a watch watching the second hand with one eye whilst covering the other. I had the unit built up but the blasted little Arduino that I was using failed on the raw in voltage. So I took a bit o strip board and soldered up one of these little guys and added it to the case, and vola! I have the device for my good wife of over 48 years. Added a small toggle switch to control it all, as well as a push button to shunt the reset pin to ground, soldered her all together then stuffed her in a plastic box, so she can reset the ...

    How to Make a Bench Power Supply

    A few years ago, I built one nearly like that, only I powered it with 6 18650 batteries, she does a great job when building, and can easily power most of my projects. I have another in straight 12 volts with a volt/amp meter like that but with cables so I can use it to test projects I am powering with it. The batteries all came from torn down laptop batteries. I find when tearing them down, there is uaually only one or two bad cells the rest seem to be in great shape. Shame how most folks throw away their spent lipo batteries from laptops.

It was a "modern" looking set pretty much a rectangular wooden box with the speaker along the bottom and the tuning setup above. Instead of a light (this ran on batteries after all why waste energy) she had a little red spot that flipped up via a spring loaded device to show when the set was on, and retreated when she was turned off.

Instead of a light (this ran on batteries after all why waste energy) she had a little red spot that flipped up via a spring loaded device to show when the set was on, and retreated when she was turned off. The quality of the sound was remarkable from what I recall, of course back then I had exceptional hearing, unlike today when I depend on hearing aides to amplify sound, the reproduction of which falls well below the quality of that old AM set (FM was unheard of back then). My plans are coming together, I have rescued an amplifier from an old set of speakers for a computer, the speakers themselves are going to the garbage, to be replaced by speakers that I picked up at a yard sale, the label proclaims them BOSE but now days, who knows. Being an amateur woodworker/electronics hobbyist, I look forward to combining the two loves to make one nice looking set. I found a supposedly 100 watt amplifier, as well as a blue tooth receiver that currently is residing in another set of speakers, which are going to the dumps after removing my bluetooth device, since the power supply is producing an annoying hum, I am sure the caps are bad in it but I don't think it is worth the repairs any more, it was an old TANDY speaker set made before anyone else ever put out a set as far as I can remember. I purchased it when I was still playing around with my old Commodore C=128 in the very early 1980's so I can't blame it for having some leaky caps after all those years of use. I had already replaced the volume controls as they were so scratchy that they were nearly usless but to recap her, that is just to much work

    Old Laptop Screen Into Monitor

    GOT mine working today.

    Yes indeed, I tried one of those 5 dollar boards, and that is exactly what you get, just the board, no keypad, no inverter for the screen, just the board, oh and mine came with a remote control and receiver. I tried buying all the parts seperately and found it was not worth the effort, I went with the outfit recomended in this article, they are super and worked with me to get a working system for 34 dollars, I got one with HDMI input as well as VGA and USB. The only problem I have with it is trying to get the unit to speak English as I don't speak Chinese, but the board sure wants to.

    DIY Power Supply for 5V and 3.3V

    I love it!! I do have one that I built a long time ago that steps the 5 volt USB down to 3.3 volts for those projects, and several power banks that I built from salvaged laptop batteries with an adjustable power supply one from 1.25 volts to 11.6 volts, and another from 12 volts to 24 volts as well as my super pack that runs at a straight 32 volts for 50 and 100 watt LEDs. This, however looks like a great little project to have on my desk for instant relief. Perhaps I will build this and hook up several 18650's for power. I think, if I dig around, I do have one of these that I ordered off Ebay that does exactly the same thing, but it isn't as much fun as building your own.

  • DIY USB Altoids Speaker. (Super Easy)

    Me to, I have a lot of projects built in these little cases, and I think I have the majority of the parts laying around the house somewhere. Might just do a bluetooth one as well. I recently built a bluetooth stereo speaker set out of some old cheap stereo speakers from the 70's they sound fair but not great. Of course I left the majority of my hearing in Nam so nothing sounds great any more.

    $3 Emergency Solar Radio

    I have dozens of old drills laying around but when it comes to these cans, I never use them. I simply use screwdrivers to punch the holes. I start with a small driver and work my way up to the size I need. The tin is so thin that it is easy and much quicker then drilling.

    Cool indeed. I would put one of these together, but here on the great plains of South Dakota, FM radio is only a dream that is realized when we travel to bigger cites where such signals exist. In fact here in the small town on the prairie where I exist, even Ham radio operators such as myself need a very tall antenna to reach any other Ham's even on common talk around bands, such as the 2 meter. The only option would be an AM radio, and as such would not be very useful in an Altoids Can.

    Man I gotta say, this type of project must do wonders for Altoids sales! I never tried an Altoids until I got into project building. Now you can find me sucking on these wonderful little mints day and night, just to get those cans empty so I can do another project. My most recent was an Arduino based oscilloscope that fits the can nicely with a small 84X48 monochrome screen, using a 9V rechargable battery as power supply.

    Make a Ring from a Nut

    I made one of those back in 1967 to give to the first girl I ever made love to. She was impressed. Not as impressed as a silver or gold ring, perhaps but impressed none the less. It was made out of necessissity back then I didn't have a lot of money and wanted to protect my investment in that gal. She is now long gone, as is the ring I guess, probably rusting at the bottom of Flat Creek Lake, where we had our parting of the ways. It was a fun make none-the-less, I made it round except for one flat that I left sort of like the mount for a stone on a regular ring.

  • Arduino Digital Magnetic Compass (HMC5883L - 2 display modes)

    I made it, and it works good for me. Perhaps a bit slow in reaction to movements but I don't think I got the sensor level. All wiring was done with cat-5 scrap wire. I used a nano instead of uno to save space, and mounted it on a perfboard, a second perfboard was used for the switch and buttons, all mounted in a small black project box, the front being cut out with a knife to allow the screen mounting. The board and sensor are held in place with hot glue, screen mounted with two stand offs (I only had two of that size) and I am using a USB cable for power, and in case I need to adjust the programing.

When I went and removed the old versions (based on the create date) and the old version of the Adafruit sensor library things began working once again. Guess that's what I get for always transfering my librarary files to new computers when I set them up.

  • Master a perfect inline wire splice everytime

    Way back when Christ was a Corporal, I attended the Field Wire-man course in Fort Leonard Wood. (1970). We were dealing with a bit different wire back then, the old field wire consisted of two conductors, twisted as a pair. Inside the water proof nylon cover were (I believe) five steel wire strands, and six copper. We were taught to strip back the wire, after striping back each conductor the length of the pliers, and tie a square knot, then cut the steel wires leaving enough to reach the cover. Then we wrapped the copper wires over the steel conductors till it met the insulation, then tape it with two coats of rubber tape, going first up then down the splice. In order to pass the course, the entire splice on one side must fit under a dime. There was no solder, of course since this ...

As far as hard drive destruction, I have a nice collection of magnets as well, I am regularly given computers to destroy, as the folk here abouts don't much trust the 5 buck an hour bums that the city puts out at the dump to direct depositing of garbage in the proper pile. Being a disable police officer/paralegal/vietnam vet, I am respected and trusted in my home town. I also make some nice wind chimes using the platters as wind catchers after drilling holes in them to nuke data.

Back when I was repairing laptops, my friends having heard of my love of old batteries often dropped off their old laptop batteries when they purchased replacements. They still do when we are on break in our home town. You can easily purchase the battery holders off ebay in 1-2-3 or 4 cells depending on your desired output voltage, thus saving the danger of soldering on the ends of the cells. In my early days I did solder many of them and never had one go bang on me, perhaps I was just lucky or just plain stupid to try but that is my experience.

  • Easy 5 Minutes USB Solar Charger/Survival USB Charger

    This looks like a fun project. I found a backpack solar panal used on Ebay for ten bucks some years ago and it works wonders. Last winter we were snowbirding it in Arizona and came upon the most bueatiful place on the planet (at least to me, and I have been many places!) called the Organ Pipe National Monument. We stayed there a week in our Class A motor home. The park had no water or power for campers, so I tried that little solar panel and it worked wonders, keeping both our cell phones and tablets charged daily. We were allowed to run our generators for 2 hours per day, once in morning and once in afternoon to charge our 12 volt systems so this was a great aid when our cells needed attention during the "off" hours.
