Do you like photography? Do you also like blasting yourself with radiation? This instant X-Ray project is perfect for you! Actually, you won't be blasting yourself with radiation, as these exposures can take a long time to make (so when we say "instant", we mean you're using instant film). But one of the ingredients called for is "radioactive material." I don't think you can find that at your local supermarket, but don't worry because our friends over at United Nuclear have got you covered. Alternatively, you can use a human as your radioactive source if they have recently undergone chemo therapy or been injected with other radioactive drugs. [via]
You can't trust everything DIY related that comes out of metacafe these days, but this simple popcorn popper made from an aluminum can looks like it might actually work. Then again, it could have been the low-budget infomercial music that really soothed any doubts I had.
I foresee popcorn getting stuck inside the contraption, so proceed at your own risk. Hit up the comments and let us know your results.
Oh yeah, if you need something to heat the sucker up on the go, why not make one of these handy aluminum can stoves. It would match perfectly!
Wisebread has an article up on how to make your own moon sand. This stuff is pretty expensive for being just sand - something you just might be able to find for free at any beach. Moonsand isn't much different than regular sand other than one secret ingredient: cornstarch. Go make your own moon sand for pennies on the pound! [via]
This awesome kayak project has an entireÃƒâ€šÃ‚Â website dedicated to it! I recently decided to purchase a kayak for my darling (non)husband, but first I looked into building one. Between a one year old, diyhappy, mystery shopping, interior decoration, and holiday crap, I don't think I have time. Oh well. Three hundred bucks later? Shipping on December 28th. If anyone finishes this kayak before then, I'll pay you instead! : )
Our friends over at Photojojo sent us this awesome feature:
How to make a fisheye lens picture out of a pair of old glasses and some tape! We thought this was totally cool, so we decided to post and see if anyone has done any cool DIY mods for film/photos lately! Hope this inspires you photophiles!
Here's the intro for this interesting project:
"In late 2004 and early 2005, raving reviews about the $30 Sonic Impact T-Amp started to surface. Some called it a "Giant Killer", some did not like it, but most agreed it was an inexpensive audiophile-grade amplifier. The favorable reviews had me wondering about Class-T amplifiers so I decided to try one on for size. Taking the DIY route, I opted for a $39 AMP6 kit from 41hz.com.
The AMP6 is a small amplifier that uses the Tripath TA2020 chip and includes an onboard regulated power supply. The manufacturer, Tripath Technology, Inc. describes Class-T amplifiers as offering both the audio fidelity of Class-AB and the power efficiency of Class-D amplifiers. "
Ãƒâ€šÃ‚Â For all ye jolly jews out there, here's a sweet post made from one of our friends in Israel, Ori:
"I drooled over the microcontrolled mini led ÃƒÂ¢Ã¢â€šÂ¬Ã…â€œmenorahÃƒÂ¢Ã¢â€šÂ¬Ã‚Â by evilmadscientist.com
but figuring S&H to Israel and having to swallow my pride purchasing anything in kit form, I figured there must me a better (i.e. more complicated) alternative. Just in time for Hanukah 5768, I proudly give you the DIY electronic Hanukiah!
0. Using an LM3914 DIP-18 led-bar driver we shall build a geeky unkosher LED Hanukiah. The more you rotate the potentiometer, the more LEDs light up. Recommend adding 1 led ÃƒÂ¢Ã¢â€šÂ¬Ã…â€œcandleÃƒÂ¢Ã¢â€šÂ¬Ã‚Â per Hanukah day although that wonÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢t make it any more kosher. The electronic Hanukiah will double as a variable nighttime <s>porno</s> gizmodo surfing light when youÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢re done stuffing down all those Sufganiot.
If youÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢re not that much of a geek, hereÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢s the place to note chip package pin naming convention (counter clockwise from the notch) and that the LED anode (+) is the longer lead leaving the short one to be the cathode (-).
1. You will require a battery holder for 4 AAs which will be modified to hold 3 AAs and a trimmer potentiometer A.K.A "trimpot", anything between 10K & 1Meg will do.
The trimpot should have a control rod if you don't want to use a screwdriver at the holiday table and the LEDs can be any color and size, but I recommend a type with long leads and a large viewing angle (i.e. not-focused since the idea isn't to light the ceilingÃƒÂ¢Ã¢â€šÂ¬Ã‚Â¦)
2. First, figure out where you want 3 batteries and where you want the trimpot. Using a wire, connect between the contacts where the trimpot goes and rip out one of the battery terminals so you have a perfect hole for the rod.
3. With the trimpot I used, I drilled screwed a hole through the separation near the trimpot position and bent one of the trimpot legs to fit it.
4. Insert the trimpot leg into the hole and connect the control rod on the outside. Make sure the leg doesn't short to the battery contact.
5. Connect the exterior trimpot legs to the (+) & (-) battery pack outputs using some wire (red & black, respectively) and a third wire (white) as a new control output wire.
That was training. Put it aside, and now for the fun part:
6. WeÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢ll be soldering the SHORT leads of 8 LEDs to pins 10-13 & 15-18 leaving pin 14 unconnected (for symmetry)
Take an LED and bend both leads into an S shape to make the extreme left "candle" repeat for extreme right.
Bend BOTH leads into shape (unlike the picture) and bend the long (anode) lead a bit back so it won't disturb you.
Solder the short lead to the extreme pins 10 & 18 (make sure the chip isn't upside-down!) and bend the long lead to the other side without soldering.
Continue with the two central "candles" on pins 13 & 15. You will need to chop some of the lead to get them all in line.
7. Carry on with all LEDs making more pronounced curves as you stray away from the center towards the edges. Keep all LEDs upright at the top.
The LEDs already in place will help you position and curve the intermediate ones in an esthetic manner, solder only after the LED fits nice.
8. Make sure all is straight and fix the crooked ones. ThereÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢ll be no fixing later.
9. Chop the long, dangling leads to be just at the chip package top and bend them back to the middle of the DIP package.
10. Solder a wire across the tips and solder all tips to it. Again, start with the extremes and continue with the others.
Bend the center wire around the chip and solder it to itself on the bottom side.
11. Add the Shamash: solder the LONG lead to the horizontal wire and bend the SHORT lead just below the edge of the DIP.
Solder a second wire from pin 1 to the bent cathode (which won't reach pin 1 without help)
12. Bend the resistor in an inconspicuous manner connecting pins 6 & 7 to one side and pin 8 to the other. An SMT resistor will be fine too but I find the regular Ãƒâ€šÃ‚Â¼W more appropriate for the DIP.
The resistor will set the led current I(led)=12.5/R or 18mA with my 680 Ohm resistor. DonÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢t go over 30mA, you donÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢t need the brightest Hanukiah in the room.
13. Turn the chip upside-down and solder pins 3 & 9 to the central wire (+), then connect pins 2, 4 & 8 (-) together with insulated wire.
14. Take the battery pack we made, solder the red (+) to the central wire, solder the black (-) to pin 2, 4 or 8. Solder the control trimpot to pin 5.
I opted on replacing the original battery pack wires with some long, thin, 4-conductor earphone wire but the conductors are very fine and varnished and are a pain in the tachat to solder. I also glued the wire to the DIP underside with superglue.
15. That's it! Turn the knob and theyÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢ll light up one by one. Remember to take out the batteries or add a switch (possibly where the 4th battery is jumpered) because the batteries will drain through the IC and potentiometer even when the LEDs are all off.
HAPPY HANUKA and HAG SAMEACH!"
Ãƒâ€šÃ‚Â Yeah, what he said!
If you've ever wanted to tie some decorative bows for a holiday tree or scheme, here's where you want to look to learn how to make them! Pictures posted soon!
