This isn't much of a project, I think this is kind of a tutorial. So I'm going to show you how to freeform a bicore. Freeforming means soldering components together, so it makes a circuit, without a PCB. And a bicore is a simple circuit witch can be used to flash leds, turning motors etc. Building freeformed circuits takes some skill and right kind of tools. Let's get started!
Here are components needed:
1x Â Â 74AC240Â IC chip
2xÂ Â 22nF ceramic capasitors
1x Â Â resistor (1 - 3.3Mohms)
some thin electricwire and peeled thin electricwire
Soldering iron, pliers, solder, wireclippers etc. And some soldering skills.
Bend IC pins just like shown in the picture(IC notch is on the right side of the picture and IC is turned pins up) and solder the two spots, that are shown.
Now take some peeled thin electricwire and cut it two suitable pieces and solder them as picture shows.
Take a piece of shielded electricwire and solder it like picture shows.
Now it's time to put on those 22nF ceramic capasitors. Solder them on shown places.
Now solder these two thingies as shown(these will be out1 and out2)
Now take your resistor(the higher value it is, the slower led's flashing rate, I used 2.2Mohm) and solder it's leads to the spots marked on red colour.
This is how the resistor looks like on backside.
Hook-ups:Â Connect your led's, motor's... leads to out1 and out2 and 3-5 VDC voltage to marked places.
