Quiz Master
From Bob's Basement
delrac Project Leader: Gandalf
Status: Prototype
Source Code: http://www.char.tv/quiz2.asm
Problems: Code will function in Velleman K8048 PIC Development Board but not in our breadboard.
The 'Quiz Master' is simply that. A piece of hardware for the average pub quiz. It features 4 player paddles and control kit featuring reset. The interesting bit, being that we are controlling it with a PIC and not a network of 8 transistors. A lot harder to design and build, but very easy to redesign and scale for more players, wireless paddles, score keeping, et cetera.
Schematic:
BOM:
4 x momentary push button - JM01B, Sub Min Push Sw Blk, £0.84 each
1 x momentary push button - JM47B, Sub Min Push Sw Red, £0.84 each
4 x LED - CJ58N, 2mA 3mm SB Red LED, £0.31 each
10 x 10K ohm resistor - N63BH, E3 Resistor Pack (16 values x 30) £6.51 per kit
1 x 16F628 Pic microprocessor - RF03D, PIC16F628-04/P, £3.12 each
1 x PCB mounting triple AA battery holder - CL18U, PCB Mtg 3AA Batt Box, £0.49 each
3 x alkaline (1.5v) AA battery
1 x piece of bread board - AG09K, AD101 Plugblock, £3.34 each
Wire, preferably in two colours of your choosing
Solder
All of the above part numbers are Maplins. Total kit cost = £18.90, plus batteries, wire and solder. Yes we aware that we can buy these components MUCH cheaper elsewhere but time was of the essence.
