moncler outlet kids Turn Signal Biking Jacket moncler outlet kids

moncler outlet uk This tutorial will show you how to build a jacket with turn signals that will let people know where you’re headed when you’re on your bike. cheap moncler jackets mens We’ll use conductive thread and sewable electronics so your jacket will be soft moncler outlet store and wearable and washable when you’re done. You need: LilyPad Arduino main board FTDI connector mini USB cable LilyPad power supply 16 LilyPad LEDs (note: these aren’t available from SparkFun yet, but will be soon) 2 push button switches a spool of moncler outlet woodbury 4 ply conductive thread a digital multimeter with a beeping continuity tester. Make a sketch of your design that you can refer to as you work. The photos below show the sketches for my jacket. (The 4 ply silver coated thread from SparkFun that comes with the LilyPad starter kit has about 14 ohms/foot.) Depending on what modules you’re using in your construction, your LilyPad can moncler outlet online draw up to 50 milliamps (mA) of current, or.05 Amps. (14 Ohms in the conductive thread that leads from the negative terminal of the power supply to the negative petal on the LilyPad and 14 Ohms in the conductive thread that ties the positive terminals together). This means cheap moncler sale we can expect a drop of 1.4 Volts (28 Ohms .05 Amps.) This means that while 5 Volts is coming out of the power supply, the LilyPad will only be getting 3.6 Volts (5 Volts 1.4 Volts). Once the voltage at the LilyPad drops below about 3.3 Volts, it will reset. The resistance of the traces from + on the power supply to + on the LilyPad and on the power supply moncler outlet prices to on the LilyPad should be at most 10 Ohms. Plan the distance accordingly. This will give moncler uk sale you a good sense of what your final piece will look like. I recommend gluing or sewing the battery down before starting on the rest of the project. If you are determined to moncler womens jackets forge ahead with a delicate fabric, choose the location cheap moncler jackets for your power supply wisely. It’s the heaviest electronic module, moncler outlet sale so put it somewhere where it will not moncler sale distort the fabric too badly. Cut a 3 4 foot length of conductive thread. Thread your best moncler jackets needle, pulling enough of the thread through the needle that it will not fall out easily. Tie a knot at the end of the longer length of thread. The knot at the end of the thread will keep the thread from pulling out of the moncler uk outlet fabric. Now make a stitch going into the hole in the hole in the + petal on the power supply. It is the most important connection that you’ll sew in your project. You want to make sure you get excellent contact between the petals on the power supply and your conductive thread. Go through the hole several times (at least 5) with your stitching. Keep sewing until you can’t get your needle through anymore. Just like you were cheap moncler jackets womens with the battery petal, you want to be extra careful to get a robust connection here. This stitching is making the electrical connection between your power supply and LilyPad. Measure from power supply + to LilyPad + and power supply to LilyPad. If the resistance of either of these traces is greater than 10 ohms, reinforce your stitching with more conductive thread. The red light on the power supply should turn on. If it doesn’t and you’re sure you flipped the switch, quickly remove the battery and check for a short between your + and stitches. (Most likely there is a piece of thread that’s touching both the and + stitching somewhere.) You can test for a short between + and by using the beeping continuity tester on your multimeter. It moncler usa should blink quickly each time you press its switch. Once these connections are working properly, turn off the power supply and remove the battery. Insulate your power and ground stitchingSo, your jacket is now full of uninsulated conductive stitches. This is moncler sale online fine when a body is inside of it. A body will prevent sewn traces from contacting each other. But moncler online store when the jacket is off of a person and you bend or fold it, traces will touch each uk moncler outlet other and short out. To fix this problem, cover your traces with puffy fabric paint (or another insulator like a satin stitch in regular thread). Attach all of the petals of the lights together and then to either cheap moncler coats mens the petal on the LilyPad or another LilyPad petal (petal 10 for me). Be careful to avoid shorts; don’t let one sewn trace touch another. I mounted mine on the underside of my discount moncler jackets wrists. I found a good spot by trying out different places. Sew 1 leg to the switch input petal on the LilyPad and another leg, one that is diagonally across from the first, to ground or another LilyPad petal. I used petal 6 for the switch input on the left side and petal 12 for switch input on the right side. I used for the connection on the left side, but petal 4 for the connection on the right side. They’ll flash to tell you what the back of your jacket is doing, so make sure they’re in a visible spot. Sew the + petals of each LED to a LilyPad petal and the petals of each LED to the side of the switch (the trace you sewed in the last step). I used petal 5 for the LED + on the left side and petal 3 for the LED + on the right side. Pressing a switch when the corresponding turn signal is on should turn the signal off. Pressing both switches at the same time should put the jacket into nighttime flashing mode. The wrist mounted LEDs should provide feedback about the current state of the jacket. You may have to make moncler outlet some small adjustments first depending on where you attached lights and switches. Play with delays to customize your blinking patterns. To limit the effects of corrosion, insulate and protect your traces with puffy fabric paint or some other insulator. You can also uk moncler sale revive exposed corroded traces with silver polish. Try this on a non visible area first to see what it does to your fabric! moncler outlet uk
