I know most of the circuits on the 3-pin e-block devices sold by GHI for FEZ are pretty easy, but it would be cool to have the circuit diagrams in the brochures. I’m working with some kids on electronics and it would be good for them to see what’s there.

Let me clarify. I don’t mean the pinout of the 3-pins, I mean the diagram of the circuit that’s on each board.
Those are not available but if you have one in mind I can draw something up.
Thanks Gus! I think for the students I’m working with the button, LED, potentiometer, and buzzer would be cool. We can go over general ones if you don’t get to this, but it would be cool for beginners to see this in the actual docs.
L8R,

So this is to show them what is on the board? We can make a PDF covering all those, no problem. All these are extremely simple circuits. Sometimes it is just a component and a wire, no more. The question is, will these students understand electrical schematics?
I think some of the students will get it. A few of them are pretty sharp! I also found datasheets on this site: [url]http://www.active-robots.com/products/sensors/sensors-inex.shtml[/url] These might do the trick.
Stacy
Nevermind. That site only had a datasheet for the speaker…
You can easily rebuild the button and buzzer. If you like I can provide you the button diagram. It’s nothing more then a LED and a pull down (or pull up, what was it again?) resistor. Also, the LED is extremely simple.
Robert,
I appreciate the offer, but that’s not my goal. I know how to build these circuits. I’m just suggesting that the diagrams be included in the documentation. I’m working with a lot of students and I think the diagrams would be helpful as they learn. If I point my students at the site to get components, it would be good for them to be able to see how the things are made.
Thanks for the offer!
Stacy
Ah sorry, I misunderstood you.
You are right. It might come in handy to know how they are made. 8)
I would agree. It can only add to clear understanding and Kaizen! Even the simple button is more complex then it appears. A button, an LED and a switch is probably single best place to start for a student.
I had a note on this Eagle diagram that a fez pin could source only 4mH. Not sure where I picked that up at, as the NXP datasheet says something like 100mH.
BTW - Stacy. Is that your first or last name? My last name is Stacey.
Would two resistors work? The actual button uses three.
Also, I noticed many of the e-blocks have room for a 3-pin breakout pads. Never can know why someone may need/want to use them in future.
Actually, Stacy is my middle name ;D I go by my middle name because I’m a 3rd.
In the PDP BOT manual some sensors are also explained.
