R5 is live for another test run

You can drive R5 for 2 hours around my house and see planet earth through the newly installed NoIR camera module: http://www.homofaciens.de/robospatium-controlstation-R5_en_navion.htm http://homofaciens.de/bilder/sonstiges/R5-2016-07-24_001.jpg There will be another test run at 19:00CET (UTC +2) aft...

Planetary Rover

As written on the Raspberry blog ( https://www.raspberrypi.org/blog/homofaciens-planetary-rover/ ), my idea is to send a robot around planet earth. The tour is a relay "race" (it's a slow vehicle) and I am looking for landing areas. Pi Towers has made an application, but I need more destinations to ...

Thanks! Yes, as written in the source code of "IOT-Raspberry.pl", you can use avconv with USB cameras instead of raspistill. I have added some code lines to the installation script. You can chose whether there is a camera connected to your Raspberry or not and if it is, what type of camera to use. Y...

Re: I/O board of my video

I substitute 2N7000 with BSN10A (gate-source-threshold = 1.8V) and the board is working fine now. H-Bridges are working perfectly as well. I have ordered some BSN10A to test those MOSFETs- thanks for the hint. The chapter about H bridges at my project page is online: http://www.homofaciens.de/techn...

...or use an additional diode and alter the layout slightly: http://www.homofaciens.de/bilder/technik/expansion-board_007.gif Now the current coming out of the GPIO is blocked from running through the zener diode by the second diode (a normal one). The voltage at the base of the 2N7000 should be 3V ...

Re: I/O board of my video

It's the same issue with the input voltage at the sensors: The current-voltage characteristic of the Zener diode is not as steep as expected. I used just three of the GPIOs as input and output (meaning there is a Z-diode between gate and source). Luckily (for me) they are turning fully on at a gate ...

Re: I/O board of my video

Yes, the black ring must point to the gate pin or else you won't get above 0.7V at the gate and the transistor will never turn ON. So you have replaced those two "bad" zener diodes by new ones? Or did you use the same ones when building the circuit at your bread board? You can test the zener diode b...

Re: I/O board of my video

What about the voltage across the two dark LEDs? I think it takes a really long time to damage an LED during soldering and if they are damaged they won't shine at all. You could try to short the connection between source and drain at the two transistors (disconnect the Pi). If the LEDs start shining...

Re: I/O board of my video

Yes, I confirmed that. It's because the resistance of a 3.0V Zener diode is decreasing clearly below 100k at a voltage of approximately 1.5V. The current-voltage characteristic isn't as steep as I expected - the layout of the board was done "on the fly". There is a picture from Wikipedia illustratin...

The value of R2 depends on the current your sensor can provide 100k are very high (safety first) and I got a signal when operating my magnet-sensor with 12V. When you had the test run with your bread board, detecting just 1.7V: Were the GPIOs in input mode? If they were in output and switched to gro...

Re: I/O board of my video

Hi malaclypsedj, thanks for all the compliments. The disadvantage of placing too many components on a single board is that the layout becomes confusing, so it was a wise decision to use fewer and make a clear layout. In principle the wiring and soldering seems to be ok, assuming that the order of ba...
