Thanks! Good info! I usually just go with what parts I find in my drawers.Be sure to post an "I Made it!" :-)
Thanks! Might do a video in the near future ;-)
"Gum drop" caps. Had to google that one :-). You can use ordinary ceramic and electrolytics here. Or salvage from electroscrap of you really want to go cheap.
Cheap and Easy Solar Heater
Hi,For Europe, most of the components and housing can be bought trough Conrad:https://www.conrad.nl/ The switch is from:https://www.tube-town.netI didn't specify suppliers, because it depends on where you're from. Maybe someone else here can comment on good parts suppliers in the US?

Right. It's one of those 'classic' pedal switches but not sure they are all wired the same internally between different manufacturers. Here's the link with datasheet for the one I used, as in step 5: https://www.tube-town.net/ttstore/Switch/Footswitch-Standard/Alpha-Footswitch-3PDT-Latching::3695.html all the best.

Nice work, Zhollet!
Propellers will probably give you more thrust, when using the motors from the bilge pumps as compared to the bilge pumps themselves unmodified. Regarding speed, that depends on the drag force on your vessel. Just trying it out is the easiest way forward imo.
Thanks, In my case I used a 12V 7Ah Sealed Lead Acid battery. Both relatively cheap and durable. Long time ago, but I built a custom controller using a Microchip PIC and some mosfets. To control the motors from the arduino, you could do the same. PWM them using mosfet(s). Fairly standard electronic practice. :-)
The thruster in this instructables was intended for small underwater robots, not kayaks. It probably won't be sufficient.
Hi, thanks.I doubt these thrusters will be strong enough for that. Maybe build one and try it out to get a feel for how strong they are.
Thank You! Nice Clip. By Playing with the supply voltage and the resistors to Q2, it is possible to get band-shaped chaos too.
Cool use of a 555! Do you think it is possible to get it somehow working without the comparator (maybe at the cost of reduced regulation precision)?
actually, RC model manufacturers offer many propellers designed for boats, from very small (cms) up to 100mm too. check out Robbe or any other RC parts manufacturer. Eagerly awaiting your results...
Thanks! In all likelihood, a single thruster like I built won't be enough to propel a kayak, maybe 4 of them might do it. I'd say: experiment a little and see. Please post the results here.
Thanks! Also, SPICE models differ a bit per manufacturer, even for the same type of transistor. Even so, indeed the circuit is pretty much foolproof.
Had to restart a few times to get the size right, but it worked out pretty well in the end :-D
