Re: Schematic program

If you want a free open solution then give KiCAD a go. Like most CAD packages it takes some time to learn how to use it but it is worth the effort.

Re: Tandy Multiface

That's certainly true. But it's extremely handy to start off a through-hole components kit if you 'd want to build something with parts of the GertBoard. In which case, I don't mind spending a little more. I really don't think the people who develop the Raspberry are in it for the money. At the sam...

As rpdom says the reason Maplin have moved away from the hobbyist and have become more of a 'boys toys' shop is primarily about the economics of running a shop.

I'd guess that's double sided tape so you can peel of the blue covering and stick the breadboard down onto something more solid.

That is the way breadboards have been made since they were introduced in the 1970's and you will find all breadboards are made in this way. There are two types of backing used on breadboards a vinyl tape or a double sided foam, the problem with the foam is that if you don't stick it to something the...

Re: Easiest method of adding a beeper to the Pi

The 3.3V Buzzer makes a sound when connected to a 3.3V supply. There is an example of using it with the Pi in issue 4 of the MagPi. It can be a bit confusing but generally speaking if you see a part described as a Piezo Transducer or Element then it will not have its own oscilator to make a buzzing ...

C17 is a decoupling capacitor (just there to stablise the Vcc power to the microcontroler), fortunatley there is also another one near by C15 that may be sufficient. Failing that the bottom pad of C17 is the ground and the top +3.3V, Perhaps the easiest way to repair it is to put a new SMT capacitor...

Re: Q: Gertboard powered away from pi

The 3.3V Regulator supplied in the Tandy kit is an LM3940 specifically designed for 5V to 3.3V conversion with a low drop out Voltage of 0.5V and high current rating of 1A. This means that you can run the board from as little as 3 AA dry cells (3x1.5V=4.5V) or 4 rechargable cells (4x1.2V=4.8V) if yo...

Re: Gertboard proximity sensor

Haven't had time to look at it in any detail but I think the reason is probably because the Gertboard has no pull-up/down resistors on it so the inputs to the buffers are floating. Try either setting those IOs low or turning on the pull down resistors on the Pi and I suspect it will not happen.

15W iron will be fine, but some thinner gauge solder would be a good thing to have.
