I am working on a model rocket and want to add electrical parts to it via a breadboard inside.

The space I have to work with is only about 40mm wide.

Is there any kind of breadboard that can fit in this space or any way to modify a breadboard to fit in this space?

    You could get a perfboard instead of a breadboard. (Parts mounted on a breadboard on a model rocket during launch might not stay connected to the breadboard anyway) – The Photon Nov 05 '20 at 22:33

    It makes no sense whatsoever to use a breadboard in a model rocket. Not only are you lofting utterly unecessary mass, you risk unreliability from things moving under the *extreme* acceleration. – Chris Stratton Nov 05 '20 at 22:52

    use a perfboard .. it is available with and without copper pads ... https://youtu.be/Ro0_3bzqTkk – jsotola Nov 05 '20 at 23:39

    I would not use a solderless breadboard on anything that experiences high acceleration. Use a protoboard. – DKNguyen Nov 06 '20 at 00:06
  • This shop sells tiny breadboards:https://detail.tmall.com/item.htm?id=616053907371&spm=a1z1r.7974869.0.0.269c3ad492Pv5C – tlfong01 Nov 06 '20 at 01:12

    Is it a model rocket (i.e. a very small rocket) or a static model of a rocket? – Pete Kirkham Nov 06 '20 at 11:47
  • I wouldn't even use solderless breadboard on something that's going to kick around in a backpack or even the lab for a while, at least once the circuit is (as good as) finalised. I've got a prototype on the go at the moment, which I'm working on at home and work. Something comes loose almost every journey. – Chris H Nov 06 '20 at 15:29
  • @PeteKirkham its an actually rocket, that will fly on rocket motors – Aquack Nov 06 '20 at 22:06

I haven't seen a push-in breadboard that small, but you could verify the circuit on one, and then use a generic solder-able breadboard for the final circuit. These can be found at any major supplier for very low cost. I am not sure how robust it would need to be for your model rocket application, but soldering the components in would likely hold up to vibration better than the push-in style breadboard.

Example: Digikey / Sparkfun

    If searching online, use "strip board", It's a generic name for the original "veroboard". Larger ones can be cut to size. – Ron Beyer Nov 05 '20 at 23:29

    And if board size is a concern don't go with boards with fancy copper patterns made to minmize the wiring you have to do. Pad-per-hole can be made much more compactly since you choose all the connections and therefore waste no space, but takes extra effort since you lay down every wire. – DKNguyen Nov 06 '20 at 00:06

    Could also use wire wrap instead of soldering. Even used by NASA so it would be good for your home made model rocket. https://workmanship.nasa.gov/lib/insp/2%20books/links/sections/301_Discrete%20Wiring.html – Matthew Whited Nov 06 '20 at 07:45
  • Many years ago I actually took part in a launch with electronics assembled on stripboard. The soldering didn't fail, though the landing was harder than planned (parachute issues) also one instrument failed due a battery discharging a bit and getting cold on an overnight delay. – Chris H Nov 06 '20 at 15:26

eBay and AliExpress etc. carry 170 pin breadboards; these measure 35x45mm after you've removed the tabs for snapping it to another board. Trimming 2-3 rows off the end (I used a bench sander) will easily reduce it to 40mm. I'd recommend not using the last row after trimming it, and perhaps filling it with epoxy glue to give it a more solid edge.
