You can't win with colour printers. You can have cheap to buy, expensive to run or vice versa. They will all break (maybe exception of heavy duty HPs which can last a long time) (And apart from the one printer we all bought in 1963 which still works to this day of course) Corridor networked Photocopiers are the best practial solution in terms of overall uptime/TCO This is based on 15 years working in primary schools Simon PS I let reception classes have a business inkjet as you can't have them going up the corridor for prints

Sounds like you haven't unsoldered the blob of solder connecting AD0 to gnd - it would certainly explain the brownout if you hadn't! http://www.hobbytronics.co.uk/image/cache/data/sparkfun/sensors/tmp102-r2-500x500.jpg Simon

Hi looking at what you posted, I'd say your using your own motor controller board? if so, you need to create two variables called power11 and power13 and then set those values between 0 to 100 to vary the speed of the motors. If you've wired up you ultrasonic with the 3 resistors like Ultrasonic Sensor | Cymplecy (Simplesi) and connected to pin23 then jsut use the broadcast sonar23 wait 1 and then read the sonar23 sensor value (just tick the little box next to it to see its value displayed on the screen http://snag.gy/12jT3.jpg regards Simon

Hopefully they'll be able to adapt it to get the green light to show on double click Simon PS Its a really good idea BTW - I'm going to use it in my primary Scratch lessons as an extension activity

use code and /code with [] to display code - it preserves all whitespacing See what you think of this then import pibrella import time while True: if pibrella.button.read() == 1: #get time when button pressed starttime = time.clock() # wait until button released while pibrella.button.read() == 1: endtime = time.clock() # check if button held down for less than 0.5 sec if endtime-starttime < 0.5: pibrella.light.red.on() time.sleep(2) pibrella.light.red.off() else: pibrella.light.yellow.on() time.sleep(2) pibrella.light.yellow.off()

Today, I decided was the time to bring the 3D printer into school and set it up. So I picked the staffroom laptop and started downloading software for it. All of a sudden network drops out. After an hour of fiddling resetting and even percussive maint - I decided it wasn't my WiFi network but this 3 month old toshiba! Of course, when I asked someone had they had any problems with it - they said - oh yes - its terrible !!!!!!! Simon

I'm not one for just pasting working code (as its all about the learning with this stuff) but how about you publish your existing code and I'll suggest the mods needed for it based on what you;ve got so far? Simon

Redfern have got a simple forum up and running on their site Forum: Crumble | Redfern Electronics Watch out for the moderator - bit of handful I'm told! Simon

to detect double click wait for button press but just remember time when it happens wait for say 0.5 sec and see if its pressed again during that time You now know whether it was clicked once or double clicked If it is still down at end of 0.5 sec then it was held down So that should give you 3 events from the one button Simon

Turns out it took out my Friday afternoon school network but nobody contacted me until I turned up at lunchtime today And the 1st person that spoke to me said that their laptop couldn't connect to the internet. I spent 5 mins looking at it before deciding that maybe something bigger was amiss and told them I was off to look around At that point, they told me nobody else's internet was working You can't make this stuff up Simon

After 17.5 years from my eldest starting at school, my youngest finished her last uni exam yesterday I am finally no longer responsible for them in any shape or form ! FREEDOM!!!!!! :-)

I have replaced my last Buffalo AP with a shiny new Unifi I have been using them for at least the past 10 years and they've been faithful partners and VFM I haven;t felt this way since I switched off my last Win98 Machine But onwards and upwards Simon

That's the point of this thread - you can create a copy of your form and post it on here without worrying about people messing

Nothing We work on trust in primaries This is replacement for a staffroom book system

Re this thread http://www.edugeek.net/forums/cloud-services/153655-simplest-help-desk-ever-using-google-docs.html Its easy to make a copy of your form for public viewing So in the spirit of share and share alike - here's a copy of mine https://docs.google.com/forms/d/1vc5226yvC8U_vwLUfoIIh-E4nyPaI8G9WlmXvuh2tAY/viewform Simon

Just had a mains dip at home! I hope the servers in both schools nearby don't throw wobblies

As you all know - the simpler the better as far as I'm concerned. So for all Primary Techs out there - create a Google Docs spreadsheet with columns for names/dates/issue/update etc and use Tools- Notifcations to get emails when someone amends it. Stick shortcut to URL in staff public drive Job done. You can probably even make it better with a form but not tried that yet Simon

I'd love a Windows laptop/tablet thingy but this is to support Ipad usage so an Ipad it has to be My daughter has a detachable Windows laptop/tablet thingy - very impressive screen size Simon

Interesting that its been made for the online version. Also, I have a few issues about the order of the block extensions (e.g the simple ones should be at the top) But the biggest mistook is the syntax of "turn pin X on" !!!!! Turn is already the equivalent of a "reserved" word - should simply be "pin X on" Simon

I've persuaded one of my heads that it would be an excellent idea for me to have use of an Ipad in order to better facilitate tech support in the school Plus I'm picking up a Sphero tonight to "evaluate" To paraphrase that old Klingon proverb - it'd be a real shame if I kicked the bucket this week! Simon

PM Sent but I can state publicly PiFace (Codebug creators) are good people The Codebug will actually be in peoples hands within 6 weeks or earlier (my personal estimate) The MicroBit design/production state is completely unknown to general public (inc me) I expect to be working on Scratch interface for Codebug within next 2 weeks Simon

I'd have a search on the main Pi forums as I've seen quite a few posts about using it as a bridge - mind you - prob much easier just to buy a bridge but not as much fun Simon

There's a load of background stories/rumours over the similarity. I know the Codebug designer personally I'm backing the Codebug and unlikely to be a supporter of any "similar" device that appears later Simon

Sorry for delay in reading this! Scratch is a GUI prog so you need to VNC in rather than SSH to a LX Terminal session To install an X11 server - i recommend my little installer script Auto Install Remote Control for Raspberry PI (X11VNC) for non-Geeks | Cymplecy (Simplesi) Simon
