`
`Brick Simon. a memory game
`
`.'
`
`I wished to keep a true 4 keys keyboard for ease of use. A few constructions
`later, I was convinced that I needed all three sensors to get a reliable keyboard.
`
`No sensors left for the display function!
`
`when one of them is pressed.
`
`So I built this keyboard module. Keys are linked two by two by a rubber band
`loaded lever to keep them up.
`
`The two keys on the left release the pressure on two touch sensors.
`
`The light sensor on the right sees black when no key is pressed, grey or yellow
`
`The keyboard unit, integrated in Brick Simon.

`
`
`
`Brick Simon. a memory game
`
`'
`
`The display module, integrated in Brick Simon.
`
`This prototype of the display unit shows how I obtained 4 states: the left motor
`can make one turn, the right motor only a half turn. The differential adds these
`movements, when both motors are on a stop its body can have 4 positions: 0
`turn, 1/4 turn, 1/2 turn and 3/4 turn. Originally, I used white clutch gears, but
`they were still too stiff and I had to use very low motor power settings (0 and
`1). You may have to increase these values to l and 2 if you use the new 43362
`motors with higher friction.
`
`. Brick Simon User's manual
`
`1) Compile and download 5mm;in program slot 1, and InitHigthoLechin program slot 2. This can be
`done using BrichC, you can get it from hflpiflzmsourceforgeflefl.
`
`2) Run program 2, this will initialize all high scores to 5, then automatically launch Brick Simon program (slot 1).
`This initialization should be performed only once to preserve high scores between runs, after that launch program
`1 directly.
`
`3) Brick Simon will first ask for the play difficulty level. RCX LCD shows a walking 1234 pattern, waiting for a
`key to be pressed.
`
`- Level 1 (blue key): The easy one. The random color chooser is biased to produce regular sequences. The same
`color can't happen twice successively. High time out on the keyboard (20 seconds)
`- Level 2 (red key): The same color can't happen twice successively. Keyboard time out = 2s
`- Level 3 (yellow key): Color order is truely random. Keyboard time out = ls
`- Level 4 (green key): The hardest level. Color order is truely random. Keyboard time out = 0.45
`
`A separate high score is kept for each difficulty level.
`
`The chosen difficulty level is then displayed as 1111, 2222, 3333 or 4444, the RCX plays a little tune and the
`game begins.

`
`
`
`Brick Simon. a memory game
`
`4) Simon asks you to repeat a longer and longer color sequence (a new color is added at the end of sequence after
`you repeat it successfully on the keyboard). Its hand turns on the dial to show colors and plays a note (different
`for each color). You then have to key in the sequence in order. RCX LCD displays current sequence length (2
`digits left) and high score sequence length to beat (2 digits right), separated by a dot.
`
`When you reach high score, Brick Simon plays a short tune to tell you...
`
`5) When you finally lose, either because you hit a wrong key or waited too long (doh sound), program is halted.
`Press RCX Run button to start a new game!
`
`. Program
`
` The programs were written in
`
`Get the highscomnmahzatmpmgmm, and the BIinLSimganQgram.
`
`Tips and tricks used by this program:
`- in NQC, static variables (declared outside all program modules) are remembered even when the RCX is off.
`This is how high scores are kept. Moreover, the compiler assigns static variables in successive order, so
`Simon.nqc can use the values set by InitHighScore.nqc.
`
`- There is no need to remember the random color sequence. Each time the color sequence must be generated
`again, NQC random number generator is re-initialized using the same seed, with SetRandomSeed(Seed_value)
`instruction.

`
`As no fancy parts were used in Brick Simon, it was not too difficult to build a simplified version using only parts
`included inW. This version comes in three separate units (keyboard, display, RCX).
`Unfortunately, RIS does not contain colored tiles, so the display is a bit... dull!

`
`Lego compatible, compact rotation sensor
`
`This rotation sensor is based on a Boums 3315 mechanical quadrature encoder. The small size of this encoder
`makes possible to cram the entire rotation sensor in a hollowed 2x3 brick (Boums makes an even smaller device,
`referenced 3375 - see the Acrobat datasheet- but I couln't get one). It is also cheap, about $2.
`
`The main difficulty was to obtain the right electrical levels to be fully compatible with a Lego rotation sensor.
`The first try I made was to simply use a 10K ohms resistor for SI and a 22K ohms for 32, but the level obtained
`with $1 and S2 closed was too high, and the RCX counted pulses strangely. So I came up with this design which
`gives exactely the same electrical levels than the Lego sensor. It works fine, but two problems remains :
`
`. the torque it needs to rotate is rather high
`0 the mechanical contacts sometimes bounce and the RCX counts wrong. I tried to debounce the switches but
`found no simple solution. I will rather try optical forks to solve both problems.
`
`SENSOR+ -
`
`SENSOR—
`
`Here is the schematics. Sl/SZ represents the
`encoder, Q1 is a small signal PNP transistor
`(i.e. BC558) and D1 a signal diode (1N4148
`for example) which protects from power
`reversal. The sensor is thus polarised - no room
`enough to use a full bridge rectifier !-
`
`The axle of the encoder fits nicely inside an
`axle pin whose hole has been slightly enlarged
`(verify that the axle pin rotates freely in the
`2x1 brick hole with the encoder inserted). It is
`not necessary to glue it.
