  • 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.

    Giant USB Volume Knob

    Wow I do like the design. Not sure if I will make one right off, however I think I have most of the parts in my box. Not quite that large of button but a fairly big one that would do I believe. I can see other uses for this, so I am going to put it in my favorites for future use. Thanks a million for your hard work and imagination. Without witch, this would be a very boring world indeed.

    $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.

    Nokia 5110 Arduino Oscilloscope

    Built in an Altoids can with Android Nano and rechargable 9v battery

    Sorry for the poor quality photos, all I had handy was a cheap junk china camera that claims 5MP is probably .025MP. Anyhow thanks a million, I built this up in an Arduino can using a Nano and 9v rechargable battery and some clips that I also use on my home built micramp meer

  • Splitting Water the Easy Way

    Cool - I have always liked playing around with electricity, it is pretty amazing stuff, and water, don't get me started talking about water. Love the article, great way to start the day. Makes me wonder, what would happen if I put a couple of electodes in my hot coffee...

  • How to Build a 5 Port Charging Station

    I have been meaning to make one of these for our motor home, but haven't got around to it as of yet. This one looks like it may be close to the design I had in my head but I am making mine with a 12V to 5V step down transformer and an old 10 USB port hub that I plan to rewire to use the extra amperage I can put out with the step down device.

    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.

  • Interactive Menus for your project with a Display and an Encoder

    Ya you got that right, I can't make heads nor tails from that mess. Tried to untangle it but it just gave rise to a bald spot on the top of my skull where I have been pulling my hair out in frustration! Now I look like all my cousins, BALD!

    Been a long time since I was in college and used such software, thanks for clearing that up, back in '95 when Windows 3.1.1 was just on it's last leg and Windows 95 was bringing new life to the x-86 computers I did have experience with such things, but my attempt was just using word pad, and the Arduino software, and I was trying line by line, just became to much for this old 65 year old brain to untangle. Thanks for the fix.

    Improved Soda Can Stove

    Very cool indeed! Don't know if I shall ever make one of these, as I am getting too old for rough camping any more. My idea of camping now is to drive our old Class A motor home to the RV Park, hook up the electric, sewer and water, then put out the awning and sit outdoors enjoying the moment. However I sure could have used one of these back when I was a soldier in the 70's

  • 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.

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

    For those who are still batteling this to make it work, I found the error that I was having, and now I can get it working just fine: I looked above the error and found that the Arduino App was using an old version of the library files. 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. Thanks a million to the fellow who has taken so much flack over his wonderful work, this compass will be installed in a project box and mounted in our Class A Motor Home that we spend the winters, and much of the Spring/Fall months traveling in. For some strange reason the unit came with no compass on board. Perhaps it is the fact that she is 12 years old, who knows. Anyhow thanks again, you do great work!

  • 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 was done in the field and there was no heat source. 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.

    I used to buy and refurbish laptops for resale at yard sales and online. I gave it all up years ago and was left with a back room filled with old pull batteries that I replaced before selling the laptops. One day I decided to tear the batteries down for components. I found the majority of the batteries had either one or two cells that went bad, the rest were recoverable and very useful. I now have plenty of power banks, and several home built power supplies in small plastic project boxes with adjustable boards to regulate the output, and using 18650 holders filled with those very cells. Having tossed the bad batteries I have had great luck with these and they serve me will in my arduino and esp8266 projects built while we see the USA in our motor home. 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.

    Arduino Wireless Weather Station

    Good project, had it going togather nicely till my iron slipped when soldering the pins and melted the solder on my main chip of my old MEGA. SHES DEAD JIM!! Well I think she is, I spent the last hour and a half trying to clean the blob of solder that is connecting one entire side of the chip into one contact but everything I try seems to make things worse. Guess I don't really need this item anyhow, still have all the other parts to make other toys. Thanks anyhow.

  • 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.
