I suggest soldering the wires to pinheaders (especially the ones for power). That will make it much easier to connect them to breadboard.

[@VincentFischer]

I would use a male dupont connector and housing

[@davidpyper1688]

Great Video. It will be fun to see what you do with it.

I've got a bunch of different wire strippers and I still grab my cutters to strip wire most of the time.

[@SimpleElectronics]

This is what I fear will happen if I buy wire strippers lol. I love the silicone insulated wiring because you can use your thumbnail to peel it off super easily!

[@maheshkafle]

This is very small ! Does it works properly? Does it get heated when operarion?

[@TimFysh]

I also use the same type as BigClive they are adjustable for all sizes they are available from many sellers.

[@frankowalker4662]

You could always use an 8ohm resistor with each speaker instead of using 2 speakers per channel.

[@SimpleElectronics]

You are 100% correct, and I only thought of that after filming the episode /facepalm

I’ve slept to this video for the past few days. /srs Please review more of the Pam boards, there’s an 8610 one and I think you should review it! - Sunny

[@SimpleElectronics]

Thanks for the feedback!

[@srilakshmi9100]

can we use one speaker instead of two

[@mahlapropyzm9180]

I have these which work very well for thin wires up to the inner strands of regular mains cable. The outer sheathing was too thick to fit in to them though and has to be removed old school style: www.ebay.co.uk/itm/SELF-ADJUSTABLE-AUTOMATIC-CABLE-WIRE-CRIMPER-CRIMPING-TOOL-STRIPPER-PLIER-CUTTER/372725474397?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649 Andreas Spiess reviewed a bunch (kzbin.info/www/bejne/b3WqopyndpmnkNE), including one similar to the ones I have, he discounted his because the cutters were poor. My versions has seemingly longer cutters, made of some proper steel though still not replaceable. I'm happy with mine so far though there is an upper limit on the wire size that can be stripped. It claims to do 10-22 AWG.

[@maheshkafle]

you should connect 5-10 watt 4 ohm speaker

[@TimFysh]

The wire strippers I use are very similar to those used by Andreas Spiess see kzbin.info/www/bejne/h5-xop95aqismqc I've had mine for years I'll try and find a seller

[@Suraj_Thakur_XD]

This cost 0.35usd in India 😃

[@jeffm2787]

These things toss out far too much RF for my tastes. Really bad if you run long wires off them. Probably not even legal to use in most countries. I like Class D amps, just not the PAM8403 or 8610's.

[@wiigay]

was there an actual spider on your arm? also thank you for this video. I'm working on a speaker project too.

[@SimpleElectronics]

Yup actual spider! My workshop is in the basement so not unheard of, for sure!

[@wiigay]

@@SimpleElectronics OH DEAR!! @_@

[@jjab99]

Are you building a talking robot??? Have fun, Joe

[@SimpleElectronics]

No! But great idea!

[@simontay4851]

22:40 "they're not very high quality speakers" ya think? No shit sherlock. Why didn't you test it properly with some better speakers. Say some 2W 8ohm ones from a portable stereo, a TV or headphones.

[@SimpleElectronics]

I want this form factor and I have these on hand.

[@englishrupe01]

Interesting video, thanks.....but i do wish you had played some actual music, not that.... crap.
