![]() Generally there are two ways of going about this: Take note that I’m working with a pad per hole perfboard so the interconnects between pins have to be made manually. One can make contacts between pins by creating a solder path underneath the board. ![]() The advantages of creating a solder path is that it appears much neater (since there won’t be anything on the board other than the components). ![]() However, the problem lies with the fact this requires a lot of skill to pull off and is extremely tedious, especially if adjacent solder paths accidentally join to form one messy blob while they’re still molten. The only way I’ve found to fix such a problem is to solder sucker the whole mess and start again, which is generally extremely frustrating and not to mention, a waste of solder. One must also consider that solder paths are not able to ‘cross’ one another (the only way to pull of a junction is to use an actual wire to 'jump’ the row that already has a path).Īn actual physical wire can be used in a point-to-point fashion. For this project I used standard 22 AWG solid core wire as the interconnects. While this quickly adds to the bulk of items crowding the top of the board, as long as a systematic order is followed, you’ll find that a predictable and orderly pattern quickly develops, which can also look quite neat, as in the picture at the bottom of the post. The only downside of using this method is that the board becomes very crowded and a lot of wire is required. Majority of the connections are point-to-point, however there were a select few that I had to go with a solder path in order to keep things under control. ![]() Though generally, they are confined to the points between ICs and the interconnects, as shown below. Major components that are already soldered onto the board have been described in the #1.00 update. Specifically, the ATTiny84 microcontroller, DS1307+ real-time clock and the MAX7219CNG LED controller IC. The DS32KHZ temperature-compensated oscillator is also about to be soldered in. ![]()
