Re: Getting the codes from rf outlets using Piscope

Uffe78, Below is a link to a site which I used a year ago to capture signals from a multitude of different remotes. I was able to capture and use the codes within my projects except for one remote (I believe this code used a larger code than 24bit). I will also mention that I did not attach an aeria...

Re: Can't decode 433mhz RF signal

Theraspberryguy, If you could answer a few quick questions it will help answer your question, What 433 MHz receiver are you using? How have you wired the 433 MHz receiver to your Raspberry Pi? Have you installed WiringPi and some form of 433 Utilities, such as 433Utils by wolfeidau? Regards, SigmaDan

(HELP!) Raspberry Pi as Bluetooth Receiver

Dear all, I am new to Raspberry Pi and am still learning a lot about the linux system so please bear with me! My project is to take a Raspberry Pi 2, Bluetooth dongle and use this as a Bluetooth receiver from a tablet. I aim to have a number of these based around the studios of our school to save tr...

Re: Nokia Pi LCD + Switch Shield board v2

Hi Julian, I am assuming that you are still planning to use the board as you mentioned in your earlier post? If this is the case I am not sure why at this point you are stripping code from the example? From my understanding you want to use the 'down' button on the addon board to "Start" an event, su...

Re: Circuit Design Software

Hi all, Thank you for all the replies - I am indeed looking at the testing side more than the PCB printing/layout stage. SPICE is something I will have a look into as it appears to be exactly what I need. Just need to spend some time playing as it sounds like libraries can be the difficult part to f...

Circuit Design Software

Hi all, I have a reasonably quick question which I am hoping will get a relatively simple answer! Is there a piece of software (free or commercial) that gives you the ability to use known components (resistors, transistors, IC's, etc) to create a circuit which can then be tested within the software....

Re: "Home automation" prank

Sounds scary! Even more so because of the spur that's been pulled from the kitchen. Good luck with the project, just be careful and keep an eye on heat - My PC rig alone would probably cause that fuse to pop every couple of seconds when the lights are on in both rooms.

Re: RPi to control 3 pin servos (interface required?)

Tobias, The servo you have purchased, like almost all 3 wire servos, accepts input using PWM (Pulse Width Modulation). The RPi will allow you to send PWM signals using the GPIO pins (Check other posts regarding PWM for more info). The PWM signal is sent to the servo using it's control signal connect...

Re: "Home automation" prank

Tmalm, I am a little curious about your mains power circuit. You said that the sockets in the room share the same circuit as the lights (circuit splits in the lighting rose to feed the sockets). This would be classed as dangerous in the UK and many European countries as the two circuits should be se...

Re: Control Relay with GPIO pins

A quick response to the question about filming a screen or monitor. The technical term for this is banding and it is related to the refresh rate of the screen being recorded. Old CRT monitors will suffer worst from this problem, whereas LCD or LED screens fair much better. An LCD or LED monitor will...
