Selecting correct capacitor types? (EL Inverter Circuit)

I recently purchased a simple EL kit consisting of a 4x AAA battery inverter and 2metre length of wire. The inverter itself is very noisy but I expected this having read product reviews online etc. I'm not certain whether this happens because of the natural characteristics of the high frequency circuit or maybe a result of low quality components. I heard someone mention that poor quality coil windings on the transformer only make things worse...

In any case, I am now looking to build my own inverter circuit with higher quality components.

From what I understand, a 555 timer IC simulates an alternating current and then a 1:10 output transformer produces the high voltage that the EL wire requires.
- The higher the voltage, the brighter the wire but a too powerful inverter decreases lifetime.
- The frequency determines colour (noticeable in natural phosphor blue/green EL wire).

I'm looking at replicating this circuit from makezine:


I was wondering if anyone could point me in the right direction regarding which type of capacitors I should use? e.g electrolytic / ceramic etc.

The big ones, the 100 and 47uF are going to have to be electrolytics, there's no point using anythng else. I might use low ESR ones though. The 1uF could be ceramics (XPO) or polyesters.
+1. 555 timer circuits are quite resilient. The fat caps are used for power conditioning, the small ones (ceramics are just fine for most purposes) for timing. Use metal-film resistors to keep things stable. Don't use wire wound or carbon. total crap for the use.
He broke the rules and drew schematics you could actually read!
