Re: Kickstarter to order a Raspberry Pi Zero right now

My question would be who is going to make the things? The Sony factory in Wales is fully busy and I very much doubt that a kickstarter type scheme would raise enough money for them to expand their capacity only for them to reduce capacity after all the Pi Zero's in the KS are delivered. One could ma...

I2C address.

I have dug out a SRF08 ultrasonic range detector that I brought many years ago when i was into PIC's and have plugged it into a breadboard with I2C level shifting circuit according to the recommended Philips level shifting circuit. The Pi recognises it at address 0x70 which is the same as in this ar...

Re: What are the security vulnerabilties of retaining user '

Looks to me that your port 2???? is an HTML port not a ssh port i.e. you have apache or another webserver on that port not sshd.

Accessing from starbucks means it has to go though your routers firewall, not sure that would be true if you accessed it locally

Re: Why is everything so difficult?

Having written some open source software I would say that at least part of the problem is the users. Most of them don't get off their back side to make any effort to contact the author of the software or article. Commercial developers can afford testing teams where as open source relies on the users...

Re: What are the security vulnerabilties of retaining user '

I only allow http port traffic through my routers firewall, but if I did allow access to ssh I would definitely setup fail2ban and ideally set ssh to only allow shared key authentication . Just open up any port and look at your logs, you will be amazed at the traffic probing your system for vulnerab...

Re: Lighting An LED

If I remember correctly the maximum current from all of the GPIO pins together is 16mA and any one of them can supply that current if none of the others are used. I believe the correct information is maximum 16ma per pin, but all GPIO pins must not exceed 51 mA so for all data pins that would be an...

Re: KiCad 4.0.1 for Raspbian Jessie

Your right KiCAd 4.0.1 is a significant enhancement.

You might try asking for advice on building a linux version of KiCad in the KiCad forum https://forum.kicad.info/ if you don't get any advice from somebody in the Raspberry Pi community.

I don't like the font and the lack of colour on the schematics.
Pity as if you document a circuit in Fritzing it makes it easy for others to use it in something they are going to breadboard.

Try KiCAD http://kicad-pcb.org/ Seems to do colour. CERN are sponsoring KiCAD so they have a paid developer who is enhancing.

There is a free version of Eagle but its quirky to use and I don't think it does colour either.
