suggestions for retrofitting a late1970's portble cassette player/radio

Hi, I was given a late1970's portble cassette player/radio. the electronics are dead. but the body is in very good condition. It would be cool to retrofit it as a portable amp to connect to my phone or mp3 player I want to disembowel the machine and then fill it with an amp and lithium ion battery pack. it's a bit larger than a 6 pack of beer can any point me in the direction of some instructables or sites with some info? I'm thinking of buying a small amp kit from aliexpress. thanks

HID headlamps. Good retrofit for 95 "Grand" Caravan, or electrical conflagration waiting to happen?

I am in possesion (legally) of a pair of 2003 Maxima and 2005 Volvo HID lamp sets.  I have been toying with the idea of installing them into my 95 Dodge Caravan,  but have no desire to become an electrical fire statistic.  Any ideas or suggestions as to electrical load or safety requirements needed?  I'm quite handy at kluging stuff together, but the kilovolt output at the HID transformers has given me pause.  My main concern is how to take the existing lamp wiring and making it work with the HID low volt input.  Your suggestions would be appreciated.  Thanks.

retrofit nixie clock

I've always wanted a nixie clock but am new at electronics. I was thinking, couldn't you take a regular clock that uses a 7 digit display and convert that to run nixies? For example, if you want to display an 8 you would have AND logic gates on all the digit leads so when they all are on it activates a relay (or switch thing) that causes complete the circuit from a high voltage souce the nixie tube?

Need advice from arduino expert!

So, my goal is to take an old 60's transistor radio and house an MP3 player in there, hwoever, I would like the volume knob to still work (not thinking that's an issue), but I would like the tuning know to actually affect the MP3 player, perhaps turning to certain points would activate playfolders of types of music. Does this seem like a job of arduino or am I barking up the wrong tree? I'll check back to see if any one has any input, but also please feel free to email me at notveryhotmale *at* hotmail.com. The mp3 player would be accessable to add or change up playlists, it's just the know portion I am having trouble figuring out. HELP! Brian

Retrofitting an Old, Rundown Barn Into an Awesome Work/Storage Space

Hey guys. My family just began work on a farm we bought two years ago, and soon I'll move into a new house there. The property has a huge barn (not an animal barn) that served as the central building for an old cowboy camp and a vacation home. It's cool to me because it was built by one man over sixty years ago using power line posts, some lumber, and good, old-fashioned DIY ingenuity. It's survived several floods from the river that flows only a hundred yards from it and building code since. Now, though, it doesn't serve much purpose other than sheltering a tractor built 63 years ago and providing a home for mice and birds. The place is also full of the previous owner's junk that's strewn about. As the work continues, I hope to bring the building back into glory as a very useful workshop to build many great projects that I never could inside my family's one-car garage. Storage is also an extreme necessity in the barn, and I'll need lots of it in a minimal amount of space. I plan on using my workshop for metalwork, electronics, woodworking, and mechanics. What is yours used for? What kind of solutions have you made in your work spaces and storage areas? What is interesting about them? Please comment; I'm sure we'd all like to hear your stories. -Update: The barn now has a new roof and concrete floor.

keyless ignition ?

My car already has keyless door locks. I am just looking for a keyless ignition. Doesn't have to be the same system or fob as the windows and door lock. I can install a push-button ignition switch, but I want a security circuit like the newer cars that requires the presence of a fob (in your pocket) for the car to be able to start.  The instant on-off button isn't a problem, but you need everything that goes off when you would turn the key off to go off when you leave the car, not when you push the (on)-off button. It's going in a pristine old "93 Town Car that still has all it's bells and whistles working. I think working this into the existing door/window system would be a nightmare, so I'll keep it separate and be satisfied with a second fob. So, I need some help. Should this be a passive system sitting looking for an RFID or active with something like a bluetooth transmitter in my pocket? I know I can buy a kit, but there's no satisfaction in that. I'm not really constrained by a budget, but obviously I don't want to go over the market value of the car (tho it's worth a lot to me).

High Power LED Collimating optics for projector project.? Answered

Greetings; My projector currently has a high pressure fancy schmancy bulb and when it goes (after another few thousand hours hopefully) I want to replace it with a high power (~100 watt) LED.  That's the easy part.  I can interface with the projector and convince it there is a real bulb firing up - but I need the optics.  Basically, it's a DLP projector so all the light has to be focussed on just under a 2x2cm square hole to hit the colour wheel.  The LED in question is already over that size on the diode die alone.  There are parabolic reflectors available (I think my best option) but they still have a positive beam spread - I need a shrinking beam.  It doesn't have to be perfectly collimated, but I bet that helps.  The original lamp definitely has a converging beam but its hard to measure as you can't operate the lamp with the cover open (safely). SO I'm thinking diode >> reflector (like flashlight) >> convex or fresnel lens. I can't get better measurements at the moment for I'm not near the machine and its finnicky to take off the ceiling.  Penny for your engineering thoughts? What I need but have never seen commercially:  http://en.wikipedia.org/wiki/File:CollimatingLensSVG.svg LED to use: http://www.dealextreme.com/p/prime-100w-7000lm-led-emitter-metal-plate-warm-white-42807 dimensions about 5x5.5cm Reflector I have in mind: http://www.dealextreme.com/p/20-100w-silver-plated-plastic-smooth-reflector-58mm-39963 (rather wide beam still) Alternate reflector: http://www.dealextreme.com/p/20-100w-silver-plated-plastic-smooth-reflector-50mm-39974 So...what I need are lens options.  Based on my estimations I'll have several cm (up to 10cm) to come up with a good focus distance.

However, because of the new law requiring CFL-compliant lamps, the dimmer has been tampered with to prevent it from actually dimming, even though the switch is the original.

So if you purchased a used ambulance... What would you do with it?

I work at a private ambulance company, and I made friends with the head mechanic and found out he may sell me a used diesel ambulance, fully functioning, for a little more than $1000. In order to justify my purchase, I would need an idea of what I could construct out of the ambulance I would now have in my possession.  My first thought was: A-TEAM VAN REPLICA I would speak with a couple tech colleges and offer them the ambulance for a semester, free of charge, for them to train on. It would be a prime example of the real world of a diesel mechanic's future career. Then go to the same, or a new tech college and find the car detailing or modification department and let them create the projected A-TEAM replica van. I would not only let them use a fully operational vehicle to modify to their liking, I would also use my above average graphic arts skills, and work history in direct mail advertising, to design a mailing to put out for them promoting their school and department of it, and then show awesome before and after pictures of the ambulance, and use it as an attentioN-getter to draw new students into their programs. A-TEAM VAN, with paint mods and maybe diesel engine modifications. ...Or I could mount large speakers in the external cabinets that i could just open up and lock them at 45 degrees, and stand in the middle of the back doors with a microphone and a couple computers mixing dance music. ...The lights and sirens and PA horns are all still in it and working.... I am just trying to drum up some of your creative passions and make you get out your thinking caps to run ideas by me and see what I might be able to do with this new toy! Lets get the ball rolling! I say an A-TEAM van would be sweet... What do you think? See attd, pictures.

Challenge: Reynolds vacuum sealer retrofit

Reynolds just put out a new vacuum sealer device for about $10.Vacuum Sealer home pageIt's a pretty neat device, but they've designed it with a flared nose and special bags rather than the small tube most vacuum sealers have. I'd like to be able to use this with regular zip-lock bags without destroying it's ability to work with the custom Reynold's bags. Anyone got an easy retrofit mod for the tip or other suggestion.A bonus ability would be to be able to use it with bags products come in, assuming they only have a small hole. For example, if I opened a bag of nuts or chips, and used a wire sealer to close the bag, I'd like to be able to put a hole in the re-sealed bag and then draw out all the air. The way some sealers do this is by having a circular flap over the hole which allows air out, but closes the hole to prevent air from getting back in. The stretchy gummy material used by magazines to hold samples and inserts would probably work well for this.I think this is an interesting product with lots of possibilities beyond the kitchen. Unlike most vacuum devices which are not portable or designed for cleaning, this one is compact and moddable. I'd like to hear other creative ideas how it could be used.

Retrofitting a battery pack into an ebike.

Ok I was just looking at this ible. And noticed the type of battery the guy used.  So I did some googling and ended up here. Wondering to myself about trying to retrofit this type of battery into a veloteq challenger from 2008 or so. Remembering that its a 48 volt pack built from 4x 12volt lead acid 20amp batteries(cells) wired in series thus to stack the voltage and not the amperage.   Now I know amperage is simply a measurement of consumption so I'm guessing that these Yellowtops are way above the usual 20amp's that the veloteq asks for but I'd imagine that shouldn't make much of a difference.  Seeing as I only want to throw on two of these as to not blow way past  the weight restriction on the ebike itself by hitting 48 volts with four of these also to avoid breaking the bank with an 800$ purchase.  Could I not add some sort of transformer to step up the voltage to 48 volts or something like this? Any suggestions are welcome but I can't imagine this would really be all that bad of an idea.  I'd imagine it should boost the range somewhat if not a fair bit.  I'd imagine that my assumptions here are not far off but I'm here to either be validated or corrected. Or even educated if someone has any suggestions or advice.

electric house windows

If windows could be closed and opened automatically, it could extensively help regulate inside air temperature- a big boon to those of us with no AC. Coupled into a remote-control house, it might reduce electrical consumption and/or increase comfort extensively. I am imagining an add-on to the type of windows that slide up and down; seems the type that opens with a crank would be very easy to retrofit, but they aren't very common, and not very insulating, in my experience.

Retrofit bug zapper with LED's, Would the high voltage be a problem? Answered

I have a large and good working bug zapper that just had the UV florescent tubes burn out. After pricing out new tubes. which are expensive, it occurred to me to try using UV LED's in place of the tubes. Physically there would be no problem. I can use a 3 inch PVC pipe and wrap the LED string around it. Secure it to the frame and replace the ballast with power supply.  Anyway, I am wondering about the high voltage which will only be a short distance away, perhaps an inch. Would the voltage effect the LED's?  Perhaps an EMF pulse? or are they pretty well isolated and protected? I am using the ones that are coated with water proofing.  Has anyone ever tried using them in a high voltage situation? I have planned on trying this and have already ordered the LED string. I am just trying to foresee potential problems.  I also wonder why I haven't seen any with LED's on the market. Am I actually ahead of the curve on this one?

Slot Load Music CD Player, to retrofit in a 1957 Motorola Radio? Help finding a CD Drive, or get a Laptop Drive to work? Answered

Hello, my Mom has an old 1957 Motorola Radio. The radio has a lot of sentimental value. My Mom keeps it on display and occasionally turns it on to bring back old memories. Unfortunately the radio no longer works, which isn't a big deal to my Mom, as she loves it just as a statue. I had an idea to remove the innards, which can easily be done from the rear of the radio. Now the front of the radio has a slotted grill design, which a CD could easily slide through it, and it would conceal the Drive, keeping the original look of the radio. In short I need any kind of slot loading drive that will play music CDs without the need of a computer. That is the only problem holding me up on this project. I want to install the CD player and connect it to small computer amplified speakers that can all be hidden inside the radio. I can even solder lead wires to the eject, skip, and play buttons. So that I can hide them in the back of the radio, or possible figure out a way to make it remote controllable. Any help on this would be greatly appreciated. Thanks so much, HandyAndy

They've moved on to a different design that makes getting parts for my mask a little difficult(their new design is dual exhalation/single inhalation). My mask is a single exhalation valve(bottom/middle), dual inhalation valve(top/sides) mask, I can attach two filters onto it if I need to. What I want to do is retrofit a hose so that it can screw in to the inhalation valves, where the filters go. I would greatly appreciate any suggestions you might have.

How would I build an electric generator with variable torque? It's my understanding that P=T*rpm, but that T is const.

I am interested in retrofitting a spiinner bike to produce electricity. The spinner currently uses brake pads to adjust the resistance. There is plenty of energy being 'lost' in the form of heat due to the brakes. I would like to be able to adjust the resistance of the bike without losing energy in the form of heat. I understand that gears are a possibility, but I would prefer to be able to adjust the resistance in a continuous manner. Any ideas? I've considered a CVT (continuous variable transmission) design, but this would be quite difficult. I've aslo wondered if the relative motion of a disk with permanent magnets to a disk of stationary coils would vary the resistance. I'm not sure what the range of variation would be however. Any suggestions or insights you might be able to offer would be much appreciated. Thank you.

Anyone have battery charger monitoring circut plans?

As we all know the biggest problem with cordless power tools is the battery life.  One of the biggest reasons for battery failier is because the companies sell the tools with cheap chargers that cook the batteries.  The tools I have use 18v nicad batteries.  The chargers are the type that take about 3-4 hours to recharge a drained battery pack.  Does anyone know where I could find plans for an inexpensive circut that I could retrofit into the battery chargers to keep them from cooking the batteries?  Idealy a circut that would detect when the battery is almost fully charged and drop down from the 'fast charge' to a 'trickle charge' and eventually shut off completely when the battery is 100% charged. Be a super nice extra bonus if I could put in a circut that monitored the batteries while in storage, maybe topping them off once a week when I go a while without using them.

variable output dc water pump for a wind generator

I'm interested in figuring out how to direct the energy produced by a wind turbine into a water pump. My goal is to pump water from a river to the top of a hill into a pond. then slowly release it through a variable water turbine so that the pond serves as a battery. i've seen pumps that work with the power take off(PTO) of a tractor that could be retrofitted if i had the right dc motor. i need to figure out what motor might work and what type of contolling i would need. also would it be better to use several smaller units that engage one at a time as the power input increases to keep the pumps closer to thier ideal operating range? The (PTO)water pump i saw operates between 17-23 hp or 20kw or less, which is perfect because the turbine is 20kw. the other thing is what if the pump operation starts at 17hp(?) then most of the power would need to be directed somewhere when producing less. maybe a series of different sized pumps and a controller to determine which pump(s) to engage to get the most water pumped.

Can a solid state amplifier be reconstructed/reconfigured as a tube amp?

All guitarists seem to prefer the sound of a tube amp over solid state. Amp manufacturers, after committing to the solid state format, hook, line, and heat sinker, must have been appalled when guitarists began to demand availability of the old school tube amps, and scrambled to replicate the distinctive tube sound by means of additional effects and eventually modelling features. But, the big boys doggedly refused to admit the error of their ways, which, as it turns out, was a good thing as new amp manufacturers began to spring up to fill the void. Finally after sitting around their boardrooms, no doubt sipping their Coke new recipes while watching their market shares dwindle, they decided to reissue some of their most popular tube amps...at six times the initial price of course. I can't afford a new tube amp. I can't afford a used tube amp. Ebay and craigslist are rife with inexpensive, (relatively), solid state amps. My question then is, could a solid state amp be retrofitted with a tube chassis and perhaps still utilize some of the solid state attributes and parts? My instinct tells me yes. However, my knowledge of electronics and theory being nil, I really haven't the foggiest idea of what might be involved with such an undertaking. To say that a schematic is Greek to me is a gross understatement. Therefore, I appeal to the genius of the Instructable contributers to comment, or even better, start a project build. (C'mon gmoon, you know you want to!) Thanks Sycan

RGB LED Bathroom shower light project problem. ?

I finished two bathroom reno's with the exception of the shower ceiling light. I started off by cutting 3 1/4: square 304 stainless steel plates and drilled out 4 holes in each for the rgb. Then assembled the rgb's into the housings and sealed them with hot glue. Then figured out the resistors based on 12 V which if memory serves me right they were 470 ohms and soldered them in parallel. Then I soldered the connectors and hot glued them so they wouldn't come in contact with each other. After installing the ceiling tiles I drilled 2 1/4" wide X 2½" deep holes through the kerdi membrane and sealed a plastic cover with foam insulation in the attic. Then I roughed in rgb cable from one hole to the other, with a home run to the controller. I tried doing a rough in trial run and it worked until one of the rgb�s burned out since they came in contact wth each other. I could actually hear it fizzle. Anyone have any suggestions on how I can make this work or are there retrofit rgb units that will fit the opening without breaking the bank? Each bathroom has 6 rough openings. That would make it 6 x 2 = 12. I'd like them to be rgb leds and be controlled via 12V adaptor and controller. If I need to start over again I have a budget of $150.00 if a another unit would work better. Thanks

Good place to get really good LEDs?

I have recently discovered that CREE has released some new XHP class LEDs awhile ago, and compared the the XML line that I have been a fan of, these ones seem to blow those out of the water. However, they are still somewhat $$$, although not too much. I would like to get my grubby evil hands on a few of the XHP70s, XHP50's, and XHP35s, but the "good" ones are out of stock on mouser and digikey. On amazon there are a few listings but they are overpriced and they do not list the binning or CRI of them. Any other reputable LED sellers? I want to see how well these would work to retrofit into either an existing el-cheapo XM-L flashlight as an upgrade, or a homemade lantern/portable floodlight. I basically want 80% or 90% CRI range and Neutral / warm white, preferably neutral. As you see I am not overly picky, but I want them for good usable indoor light quality. I have been impressed by the XML light output, but not the 6000K 70% CRI crap quality light like the ones I have produce. These LEDs are roughly twice as bright for the same physical size, and about ~30-50% more efficient. What I do want, however, is the highest binning available in it's class (aka the best ones.) Not for any particular reason (other than maybe bragging rights lol), but because I just can't bring myself to order comparatively less efficient ones with low/medium CRIs for pretty much the same basic price when I know damn good and well there are better ones for sale for only pennies more. Feels like I get cheated. :( Also if I order from mouser or digikey, I guess that means I would need to mount them to a star PCB myself, that might be a challenge. Since I do not have solder paste or a proper reflow oven, I prefer to not have to do that.

Amazon's very expensive cable, and the comments for it.

Http://www.amazon.com/AudioQuest-K2-terminated-speaker-cable/dp/B000J36XR2/ref=pd_sim_sbs_e_18 I was flipping around on Kotaku, and came across a page talking about the MASSIVE rip-offs involving HDMI cables. I read the article and found this link in the comments. This is a $9,000 audio cable from Amazon. I went down to the comments (mostly to see if some idiot bought this), and found some interesting comments. And by interesting, I mean I fell out of my chair laughing.  -------------------------------------------------- Some comments: " We live underground. We speak with our hands. We wear the earplugs all our lives. PLEASE! You must listen! We cannot maintain the link for long... I will type as fast as I can. DO NOT USE THE CABLES! We were fools, fools to develop such a thing! Sound was never meant to be this clear, this pure, this... accurate. For a few short days, we marveled. Then the... whispers... began. Were they Aramaic? Hyperborean? Some even more ancient tongue, first spoken by elder races under the red light of dying suns far from here? We do not know, but somehow, slowly... we began to UNDERSTAND. No, no, please! I don't want to remember! YOU WILL NOT MAKE ME REMEMBER! I saw brave men claw their own eyes out... oh, god, the screaming... the mobs of feral children feasting on corpses, the shadows MOVING, the fires burning in the air! The CHANTING! WHY CAN'T I FORGET THE WORDS??? We live underground. We speak with our hands. We wear the earplugs all our lives. Do not use the cables!" - By Whisper ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- "If there is one cable I would whole-heartedly trust to my Chimera-hunting needs, this would be the cable. No other cable has the tensile strength to properly and efficiently garrote a lycanthrope, asphyxiate an Esquilax or even gag a mermaid. Last week, using my trusty AudioQuest K2 (retrofitted with lead weights, bright orange latex paint and a generous coating of crushed glass stolen from the window of an abandoned church at midnight), I managed to snuff 3 golden unicorns in swift succession!  Pros: Quickly tears through scales, fur, bone, and adamantium with ease  Coils and uncoils from hip holster (optional) quickly and quietly  For a product fabricated from 1,000 Onyx Dragon fetuses, the price is unbelievably reasonable!  Cons: Shipping from the R'lyeh took far too long  Doesn't come in 10' lengths (which would be perfect for hydra, cerberii and other multi-headed creatures)  After every use, I can feel 6 ounces of my soul slipping from my core into the ether. But this may be due to the fact that I prefer to work without gloves. YMMV.  Overall, I would recommend that any hunter buy one, nay, two, of these immediately, and experience the difference that upgrading to the K2 will make in your next quest!" - By Valannin "Pantheon Outcast"
