Pre PC Era Computers (6510, 8085, do they count?) and SunSPOTs embix4-Mar-13 5:48 embix 4-Mar-13 5:48  As I guess most coders at a certain age have done, I developed for some pre PC Era computers like KC85 (uses Z80 Clone) and C64 (6510). I don't think they were ment with "Toys or Gadgets". Nowadays embedded devices are available und affordable. It became more convenient and more easy to run your own code on such mobile computers like smartphones and even embedded boards. They are everywhere. While programming a single device is fun, new challenges arise with (mobile) sensor networks as you have lots of them to run "one application" in the net. If you already have say one quadrocopter - why not use it to update the map of an NXT-Type Lego robot? I guess the future in gadget development to have a whole zoo of devices which should act toghether. modified 4-Mar-13 11:58am. FPGA chip Pawel Gielmuda4-Mar-13 2:45 Pawel Gielmuda 4-Mar-13 2:45  Once I have implemented sorting on FPGA chip Yes, some of them Jiří Miklík4-Mar-13 1:54 Jiří Miklík 4-Mar-13 1:54  russian air defense module VOZDUCH M2 Spectrum - Z80 Atari 800 - 6502C 8051 car navigation for PNDs with WinCE phones with WM6 and others Washing machine controller John Stewien4-Mar-13 1:51 John Stewien 4-Mar-13 1:51  Wrote a controller for a washing machine many many years ago. This didn't have a CPU. My memory is a bit hazy but it was basically a 4 bit memory chip where the lower 2 bits of the output data lines were fed into the lower 2 bits of the address bus. There was a water level sensor, that would also turn off the water when it was full using some logic gates, and a single bit timer that both fed into the upper 2 bits of the address bus, and upper 2 bits of the data bus went out to water on/water drain, and a Timer start/reset line that also turned on the motor when the timer was running. So it was very sequential. The output at address 0 turned on the water. When the water hit full it raised the 3rd bit on the address bus, and the instruction at (binary) 0100 turned off the water, started the motor and output 00 for the lower 2 bits still (so data is 1100 - timer on, motor on, water on/not draining but was stopped by the water full sensor). So then address 1100 (timer finished, water still full) stopped the motor, reset the timer, and output 01 to the address bus. 0101 (timer stopped water full, but at next instruction) drained the water. The water level sensor was a flip flop thing, so once full the sensor wouldn't return zero until it was empty. So then at 0001 we start the rinse cycle. Etc. Arduino!

Just blinky LED projects so far, but I'm working up to a robot Re: Arduino! Addy Tas4-Mar-13 9:41 Addy Tas 4-Mar-13 9:41  Not an Arduino but Netduino and used that to make a full sized traffic light for my kids to play with.To keep the nerd level up, the sources of the toy were properly Unit tested Toying with the physical world is always fun. Cheers, AT Cogito ergo sum Re: Arduino! DaveX864-Mar-13 10:01 DaveX86 4-Mar-13 10:01  Yeah, I did something similar with stop lights at a 4 way intersection for a model train set...haven't tried a Netduino yet, thought it would be good practice to dust off my C/C++ with Arduino...anyway, plain old Arduinos are cheaper...you can get an Arduino Nano on eBay for $11.00 Cdn or an ATTiny85 for $1.50 Cdn. Re: Arduino! lewax004-Mar-13 11:39 lewax00 4-Mar-13 11:39  Same here, and now I get to put that knowledge to use in my Robotics lab, where we're using them to run our (fairly simple) robots. It's fun to see your Arduino running away from you Re: Arduino!

DaveX864-Mar-13 12:30 DaveX86 4-Mar-13 12:30  Legos might be good for constructing stuff...heard someone made a supercomputer with Legos Re: Arduino! Brisingr Aerowing6-Mar-13 13:43 Brisingr Aerowing 6-Mar-13 13:43  I am planning on buying some Arduino's and some Raspberry PIs and making a fully 'computized' Lego city with my approx. 100+ pounds of Legos, my HO-Scale model trains, the computer things above, a lot of wires, and a LOT of time (and space)! I also am going to write a remote control system for it. That is, if I ever get enough money, time, space, and patience to do this!

DaveX866-Mar-13 14:37 DaveX86 6-Mar-13 14:37  Lol, that's always the problem isn't it?...a conjunction of Money, Space, Time and Patience...must be a formula in there somewhere... Lego NXT Kevin Drzycimski4-Mar-13 0:52 Kevin Drzycimski 4-Mar-13 0:52  does it count? we used LeJOS by the way. No! _Amy3-Mar-13 23:30 _Amy 3-Mar-13 23:30  No and not even planned.

This is why you have to prioritize Nevertheless, thx for the link I will check this out! No more Mister Nice Guy... >: |
