This is a collection of electronic components available on ebay or IC station. Most of these electronics come from sellers who I buy my components from or if I haven’t bought from them I’ve tried to find items which have a high sell count as that usually means they are a reliable source.
Hover the mouse pointer over an item and arrows will appear allowing you to scroll through the different items in a category. If you hover over the picture you can get a slightly zoomed view.
5 volt 16 MHz Arduino Pro Mini
I use the 5 volt Arduino pro mini modules in the lower half of a tractor build to control the servos and motor drivers.
I'm using this motor in a John Deere 9560R. The motor easily has enough power to break the gears if the wheels get jammed so best suited to large slow models on flat surfaces e.g. big machine ploughing a field.
This is the servo used in the lifting arms of the Massey 8680. It is very small but also very weak so it is good for lifting lighter accessories and hitching to trailers but not long heavy objects like large ploughs.
I'm using these 3.7 Volt 240mAh batteries in my Massey 8680 model and it seems to have reasonable battery life, around an hour but obviously battery life depends on whether LEDs are on or if you're pulling a load.
When you are getting started with electronics it is best to have plenty of the basic components like resistors, LEDs, jumper wires and a breadboard. These are very useful for testing out circuits before you start soldering.
This is the Geeetech 3D printer based on the RepRap Prusa i3 which I purchased through ebay and you would have seen in some of my videos. Takes a little bit of work to assemble and learn to use but it is extremely useful.
