| Improving on cheap solderless breadboards. |

I have decided to have a go at building an 8bit breadboard computer. I have scrounged up all the components needed and looking at the cheap solderless breadboards. I need about 12 x 830 pin breadboards and can't justify the cost of the top quality units. The cheap $3-5 units all seem to have a bow in them, I guess due to the moulding process. Has anyone had a go at correcting the fault in these and to what level of success? |

Bow? How big? My 830pt boards all lie flat, I have not noticed this problem. (N.B. they're crazily cheap from LCSC, so I tend to order them in batches of 5-10) |

I started with one from Jaycar Electronics that you could actually rock, which I returned. Since then I have bought two off Aliexpress (different brands) both have a slight bow. The bow is stopping the board from sitting flat on the table. I guess If I used the backing tape It would not be so noticeable. The boards also have two mounting holes on the underneath (under the backing tape) on the power rails, I could use those to force the board into shape. |

That is a bloody cheap price. @Whales, you consider them value at that price? --- Quote from: Whales on October 19, 2019, 03:37:17 am ---Bow? How big?

I've just stripped the foam off the back of a new one, it sits flat on my desk fine and I can't make rocking noises with it or feel it rocking. I suspect these boards will be made of polystyrene. Do you store them anywhere that gets above ambient temperature? Is your mailbox a dutch oven? Given that you are using them without foam on the bottom: the metal clips could be sticking out underneath unevenly. Every time you push a wire in you may push these out slightly, they're removable. Otherwise: curved desk? :D --- Quote ---@Whales, you consider them value at that price? --- End quote --- What do you mean by 'value'? They're the same boards, AFAICT, as all of the other cheap 830pt boards. Opinions will vary greatly, from my experience these do have a life limit before connections into them get very unreliable. |
