The protoboard is finished – with sockets for the wiring to the LCD panel. The project is now the GerbClock – all I need is a case to put it into!
The Arduclock proceeds very slowly – the extra bits have moved to a Freetronics protoshield– just need to tidy up the connection to the LCD and put it in a box..
Here is a closeup of the protoshield..
Power could be a 9V ‘wall wart’ plugpack or 9V worth of NiMH cells in a carrier…
a nice looking case is next…
I have used the Cheat sheet and find it very handy, but the print for the code is both proportional and small which for us older folk makes it hard to read – I have modded it to a larger monospaced font and put the pictures (bigger) on a second page with the libraries, leaving space to add some more library info later. You can get my version as a .vsd file or a pdf from http://gerbilator.org/arduino. Please note that this server is on a slow connection to the Internet, so be patient.
More power to the Mechatronics Guy for coming up with this very useful idea initially.
The Cybot has been relegated to a box for the time being. The Gerbot (pictures to come) and its little friend are Arduino-based, using Freetronics’ protoboards and a TwentyTen MCU card. They are waiting on space being made to actually work on them! (Coding of course can happen anywhere with a Laptop).
Recently, I acquired on eBay a FriendlyARM mini2440 system – it works out of the box but in Chinese! – a little work to load an English language image and it goes..admittedly its a small display with lower resolution than a modern cellphone but a lot of computing power if directed to robots – a future project.
The cleaning up is a slow process, stuff goes on eBay from time to time, but I really don’t like throwing things away – you never know when they will be handy.
Anyway, Happy Australia Day for tomorrow!!!
Well, it’s almost Xmas time again! Not much has happened on the GerbClock or Gerbot recently. Gerbot pix soon. Arduino has gone from strength to strength spawning any number of clones, work-alikes and enhancements. Even Microsoft are getting in there with their Netduino! I bought 3 very nice smallish Stepper motors on eBay recently – a 3axis mill or 3D printer…haven’t decided yet.
The ArduClock has been sidelined of late – I hope to have the code and diagrams posted by the end of April. Putting assorted chips up on eBay to free up space round here takes up a lot of time as well as the new semester has begun. Everything seems to take longer as you get older…
The ArduClock continues (albeit very slowly)..I have fitted a Dark background LCD display (from eBay) – I think it looks better: still haven’t put it into a box yet.
I am working on another clock/counter with 7 segment LEDs (HDSP-7503) High Efficiency Red – 7.5mm (0.4 inch) Char Height.
(I bought a lot of them recently) plus some huge 16 segment LEDS – see pic below..
some changes have been made; the Arduino NG has been replaced by a BBB Rev D (atMEGA168); the LM75A by a DS18B20 and the display is now a 4×20 LCD unit. The Code needs some more work before posting…I now need a bigger box to put it into! I have a nice wooden box that used to contain code wheels, but it’s not quite big enough for the LCD display..
Just using some bits and pieces, to prototype a desk clock/calendar with thermometer. So far we have an Arduino NG with a DS1307 RTC and a LM75A thermo sensor chip. The Clock/Calendar is working…
Note that the “Temp:” has no value yet. I may rearrange the display to fit a 16×2 display better. Nearly all the bits are from eBay…
Yes, folks: from the ABC news – gerbils are a new eco-horror in china!! Maybe they could catch them and turn them into sweet and sour gerbils, lemon gerbil, gerbils in black bean sauce…
[yes, yes, I know it's not technology...]
