February 28, 2013 Leave a comment

Todays blog is another “what to do with a raspberry pi ?”  turn’s out you can use your Raspberry Pi as a open source POS system called LemonPOS and maked a Open Source POS system.

What is LemonPOS ?

Taken from the LemonPOS website (site link)

“Lemon —in short— is an open source Point of Sale software targeted for micro, small and medium businesses. MySQL is employed for data management and storage, and can be used a single database with many POS terminals on a network. Being Linux or any other unix the target operating system, your information is safer against virus attacks, and lowers the costs in licenses.”

So that’s LemonPOS the next question is how do you install this software on your Raspberry Pi well you need to take a look at the following website to see how to install it on to your Raspberry Pi.

Now all is needed to connect the GP10 to a the cash till and you could have your self a very cheap POS based system.

Not quite what I meant

Todays blog is about turning the Raspberry Pi into a tank monitor system.

Designed and built by rob at thereefuge.com.au will enable you to turn Pi in a tank monitor system and upload it to live website

Tweaking FireFox with about:config

February 26, 2013 Leave a comment
To get the best out of FireFox you some times need to tweak the settings.

You can edit prefs.js directly to tweak your firefox install, but it’s often easier to change the settings through the browser window

So to do this type about:config in the address bar and press Enter, (you should see the box below) and you’ll see all the settings currently enumerated in prefs.js, listed in alphabetical order. To narrow down the hundreds of configuration preferences to just the few you need, type a search term into the Filter: bar. (Click the Show All button or just clear the Filter: bar to get the full list back again.)

Warn

To edit a preference, double-click on the name and you’ll be prompted for the new value. If you double-click on an entry that has a Boolean value, it’ll just switch from true to false or vice versa; double-click again to revert to the original setting. Not all changes take effect immediately, so if you want to be absolutely certain a given change is in effect, be sure to close and reopen Firefox after making a change

RasPiComm Plus – an early insight into the ultimate Raspberry Pi extension board

February 26, 2013 Leave a comment

Take a look at RasPiComm Plus board in development by Daniel Amesberger

It’s a multiple board connector allowing you to connect multiple units to your Raspberry Pi such as

  • 8 Inputs (5-35V), switching on 1/2 of the reference voltage with hysteresis
  • 8 Outputs (5-35V, 350mA/500mA peak with thermal shutdown and output transient protection/clamp diodes)
  • dual RS-485
  • CAN bus
  • GSM module

So you can choose  different combinations for your Raspberry Pi

Take a look at the link below to see how it’s going and also leave him a comment with suggestions you would like to see.

How to install AirPi – AirPlay on Raspberry Pi

February 25, 2013 Leave a comment

Raspberry'sToday’s blog show’s you how to have  a AirPlay system installed on your raspberry.

I wanted to stream music from my music player using my home network to serve each room

So I did a quick google and found touch.com and he had some excellence instructions on the setup of AirPlay on my Raspberry Pi

Geek2013 Report

February 24, 2013 Leave a comment

GEEK2013 took place 21st – 24th February during Half Term at the Winter Gardens, Margate.

I attended on the 22nd February on a very cold day in Margate which was bracing to say the least with snow in the air but happy to say that the Winter Gardens was nice and warm, Inside the winter gardens the GEEK 2013 area’s is broken into two hall’s

So what was at GEEK2013 ?

Geek2013

Queen’s Hall

Quite of look of interesting things in the first hall there was  a team with Raspberry Pi’s showing how easy they are to use and showing off some simple programing that can be run on the raspberry pi.

They also had a Arduino demonstrator showing what the Arduino can do and how to program it and wire it up.

And of course nGaint GameBoyot forgetting Julian Skidmore and his fignition DIY 8-bit computer kit for £20 (link below)

FIGnition DIY 8-bit Computer Kit

They also had a couple of super size gameboys as well as order LED games

Main Hall

The main hall was where the main retro action was and brought back a lot of memories from my past starting with the old spectrum ZX +2  and Amstrad from the 1980’s though the SNES and Sega Mega Drive (genesis) of the 1990’s to the Saturn and playstation 1 of the early 2000’s.

Retro PCRetro PC x 2

Of course the highlight for me was in the corner of the Main Hall where they had a setup of BBC Micro’s running some of the old school software such as granny’s garden and how to type in BASIC (BASIC Programme).Granny Garden

There was also a very poplar minecraft area which was very busy during the whole day with people making all types of interesting minecraft projects.

Final thoughts

Geek2013 is a fantastic walk down memory lane and well worth a day out to wander round the hall’s playing on old systems and games that you have forgotten about or half remember.

Two bad points are the cost of drinks at Winter Gardens with £1.20 for a single can of coke and no directions within the building to point you to the toilets or direct you though the maze of corridors connecting the two halls together.

FIGnition DIY 8-bit Computer Kit

February 23, 2013 Leave a comment

Went to the Geek 2013 show in Margate today and spoke to Julian Skidmore the designer of FIGnition who inspired todays blog posting.

To quote Julian Skidmore

“FIGnition is a simple, educational computer, but a real one, not an emulator. It has real firmware, real RAM, really generates a display and really has storage for when you turn the machine off”

FIGnition is a kit computer comprising motherboard and solder-yourself components. There’s a USB port for power, and a phone-style PAL video output so it can be hooked up to a telly as a monitor and also now has audio and comes with some nice features such as

  • Arduino-Compatible Headers (except that the second set of headers are both spaced 0.2″ from the first making them Stripboard compatible too).
  • Audio-Mod built-in
  • 2mm screw holes on 3 corners so you can attach FIGnition properly to some kind of base!
  • A proper ground plane; partial 3v6 plane and wider 5v tracks for much better signal integrity!
  • Shorter connections between Flash, SRAM and U1.

FIGnition 8-bit Computer Kit boots into a Forth language interpreter.

You can buy it from the following link for the cost of £20 – FIGnition DIY 8-bit Computer Kit
