nichrome wire

I got some nichrome wire off eBay, and it works great but when I connected it to a 9 volt battery it barley got hot, then I attached it to 4 x AA batteries and it got red hot. why is this? I don't understand because the 9 volt gives out 9 volts(duh) , but the 4x AA batteries only gives out 6 volts.

Battery Wiring?

I have new Li-ion batteries for my mac but i wasn't completely sure on how to wire it up to the old circuitry. I know that "vg" is the ground and the "vp" is the positive. I am assuming "vl" goes to the wire "vl" i dont know what that is thought.  But there is a "vh" spot on the new battery but on the old circuitry there was no wire going to there? Do I solder that wire there? There is also two very thin wires labeled ntc, i can not find a spot on the old circuitry for that is it necessary?

Microphone wiring? Answered

I have a broken microphone. Its wire is cut  inside the insulation. i want to replace the entire cable. when i removed the plastic cover of the microphone i saw a red and a black wire soldered to it.  Therefore it uses only 2 wires but in the connector it is a TRS one not a TS one. i will also replace the connector.  i am wondering how should i wire a TRS connector which has 3 leads. one being the common ground. but the other 2.  should i short them out and connect the red wire or must I connect the wire to only one lead?  Then if i buy a $0.2 TS connector and i wire it accordingly. will it work? One another question does the microphone device has polarity that is should i connect  positive to positive and negative to negative lead. because there is no indication on the Mic?

Wiring Question

Ok, I recently purchased a Go-Ped for practically nothing, and I really, really, really want to fix it up. I want to mount a couple of LED powered bicycle headlights on the front, and a tail light on the back. However, I want to be able to turn them all on and off via a single switch, mounted to the handlebars.I know very little about wiring, but I do know that most bicycle lights require physical pressure to power them on or off. Maybe there's something that can go between the batteries and bulbs?Any input you can provide would be fantastic!-Ryan

Induction Motor Wiring?

Hi, I've recently bought a Clarke Induction Motor with these specs: 230V 1 Phase 2 h.p. 1.5 kW 1330 rpm 50 Hz 9.4 Amps Capacitor Details: 50 micro Farads 450 V I have been looking all over the internet on how to wire it up to go into 240V mains (UK) but I can't find a thing. In the terminal box there are 6 terminals labled V1, V2, U1, U2, W1, W2. A brown wire connected to U2 and a blue wire connected to W2 lead off to the capacitor.  A red wire connected to V2 and a white wire also connected to W2 leads off into the motor. Another red wire connected to V1 and another white wire connected to W1 also lead off into the motor. Nothing is yet connected to U1. Please see the pictures which make this a lot clearer. (I have removed the capacitor from the blue catch for the photos) I have looked all over the internet and there seems to be no mention of anything. I basicly need to plug this into mains (therefore 3 wires, live, neutral and earth - obviously earth goes to the motor casing) So which wires go where? Also, the website of the shop that I bought it off said that a 10-16 Amp starter is required. What does this mean/do? Can you just plug it into the mains without this starter. It is probably obvious that I am somewhat of a rookie in motors! Thanks very much in advance for any help!

Silver wire vs. Platinum wire for Hydrogen Fuel Cells

I understand that most proof-of-concept hydrogen fuel cells on instructables use platinum wire. Can I use silver-coated wire in place of it, or rather, just any wire? Platinum wires aren't exactly readily available here in the Philippines, and I just want a good proof-of-concept hydrogen fuel cell that's cheap to produce. The silver-coated wire I'm referring to appears to be some sort of jewelry wire. I'm also wondering as to why most people would use platinum wire (is there a special property platinum possesses that other metals don't?). If I can't use platinum wire, then what can I use? Something preferably cheap and over-the-counter.

Ideas for a wire chess set.

I was thinking about doing a wire chess set. Since it was suggested by CaitlinsDad over here: https://www.instructables.com/community/Requesting-feedback-on-a-Fire-Breathing-Dragon-tes/ Came up with this. These are rough (obviously), the rook should have crenelations and I did the king and queen in the same piece. It's like 5 AM and my fingers hurt from working on a wire Nine Tailed Fox (from Naruto) for my son. So, I took a short cut. The picture should make it clear how I'm planning to make things look. The knight is abstract, it always bothers me when the horse is the only thing with any detail. The pawn is about 1/2" x 1" tall, the queen would be just under 2" tall, the king is about 2 1/4" tall, both by 1" wide, the other 3 are about 1 1/2" x 3/4". It is done in 18g galvanized steel. Anybody still reading? Great! I'd love to get some feedback, good, bad, anything to either confirm it is just the best thing ever OR how it could be improved towards that goal. So don't hold back. Cheers.
