MP3 Player Amplifier

Posted by dougw Top Member Apr 24, 2016
I seem to often have a need to test small speakers, but audio sources these days tend to expect the speakers to have their own amplifier built-in. Rather than always having to hijack some other system and rig up appropriate amplifiers and wiring I decided to make a small test device that can directly drive speakers as low as 4 ohms. Originally, I was just going to build an amplifier, but I found an MP3 player with built-in amp for a ridiculous price of $1.78 with free shipping so this is what I ...
The idea to make yafrd (yet another filament roll dispenser) originates trying to 3D Print some of these useful support available on internet. Unfortunately I too frequently find objects (and not only in this case) that "in theory" will work perfectly but then when having the components in your hands arises mechanical issues making them almost useless or very difficult to use or build. Some of the tools I tried was too complex, other was too expansive and in some cases requiring components t ...

Triple Gaff 3D Print

Posted by dougw Top Member Apr 2, 2016
The Triple Gaff project is a solution to carrying heavy objects with narrow handles that cut into your fingers. The Triple Gaff has hooks that grab narrow handles on objects to be carried, but the handle of the Triple Gaff has a large diameter to distribute the load over a larger surface area thus translating the concentrated high stress load from a narrow handle to a low stress load. The shape is designed to be 3D printed with no support structures. It can prevent finger pain while carrying ...
