random start cadence and controller plans

Postby bigpimp347 » 03 Apr 2017, 10:11

without sounding tight (i'm certainly not loaded)
i'm building a start gate, so far the majority has cost me nothing apart from an electro magnet £9..
so i'm looking at a way to control the magnet and use the cadence light system..
i can't justify £160 for less than £50 of wire and a board and some lights when i could buy and built it for cheaper,
but it's locating the plans to build one.
anyone know of any kits ?
you can buy timers to release the gate, but not random, and not sure how you'd link one to the cadence either.

i've read the raspberry pi can be used and a few other ideas but not been able to source any solid plans..
a bit like the i know a bloke who knows a bloke who can get type things..

so anyone know where to get a kit, or what's needed to enable a simple electro magnetic release for a start gate ??

if i was to buy a ready built one i'd probably just rip it off any way and sell it a lot cheaper :)

I made mine using an Arduino UNO which seemed more suited to the task. Think there were only about 1/2 dozen lines of code in it.
Stuck it in a Maplins hobby box & a few leds.
I didn't bother with the voice command just the red light to indicate the sequence is starting.
