Re: Falstad Circuit Simulator
I figured it would be too simplistic for the more advanced shields, but at the moment I am trying to simulate one of the channels on the relay shield, and potentially the logic level converter module in order to simulate the relay switching power to a 12V PIR sensor (http://www.jaycar.com.au/product...

Falstad Circuit Simulator
Good Afternoon, I am new to electronics and have been using the Falstad Circuit Simulator (http://www.falstad.com/circuit/) to try and wrap my head around how different circuits work. I have been trying my best to port some of the various freetronics shields and modules into the simulator, and figur...

Re: 8 Channel Relay Driver Shield
Yes, the problem was the FET. Another member of the meetup ended up having a couple spares

Re: 8 Channel Relay Driver Shield
Good Afternoon! I just wanted to report back that my shield has been successfully repaired! Ross, a helpful participant at the Sydney Raspberry Pi meetup showed me how to troubleshoot the circuit board with a multimeter to isolate the problem, and then put on a soldering workshop to demonstrate gene...

Re: 8 Channel Relay Driver Shield
Thanks for the clarification, do you happen to know of any places in Sydney where I would be able to pick up the part by Sunday? As I mentioned above, I was hoping to get my shield repaired on Sunday at the local hackerspace meetups soldering workshop as I am new and don't have the skills to do the ...

Re: 8 Channel Relay Driver Shield
Good Morning, I have just made a trip to jaycar and picked up a couple of these: http://www.jaycar.com.au/productView.asp?ID=ZT2400 Which I am pretty sure is the wrong part, but was the only part they had in stock. If I do a search for 2N7002 on the element14.com website, there are several choices, ...

Re: 8 Channel Relay Driver Shield
Good Afternoon, Thanks again for your meaningful response, I have been really impressed with the responsiveness from the freetronics team to all of my basic questions :) I have spent a small fortune on freetronics components so I'm sure there will be lots more to come as I continue to learn how all ...

Re: 8 Channel Relay Driver Shield
I was afraid of that response! I had a sinking feeling as soon as I turned it on :( Have I done damage to anywhere else on my freetronics arduino or shield? As for the wiring, thanks very much for the nod in the right direction, from the datasheet, I thought that the pin closest to the coil was the ...

8 Channel Relay Driver Shield
Good Evening, I have just purchased the 8 Channel Relay Driver Shield, along with a 12V DPDT Special PC Mount Relay (http://www.jaycar.com.au/productView.asp?ID=SY4052). The datasheet is available here: http://www.ficrelay.com.hk/details/FRM1.pdf I have wired it up according to the image: http://img...

Chapter 6: Security/Automation Sensors
Hello, I am new to electronics and using the chapter 6 alarm system project as my first project so please excuse me if my questions or assumptions are wildly incorrect. Will this project work with a single two wire PIR sensor (see the links below for the exact model)? Can I make this work with a 7V ...
