Will it blend? (Patreon)

A USB powered (OK, a USB rechargeable) blender for when you need a smoothie in non-culinary environments.

Bit of a rough start, but it came out well in the end.

Files

Pink plastic USB blender test, fail and teardown. (With schematic.)

Someone suggested I take a look at one of the USB blenders, so I bought the cheapest pink one from eBay I could find. And here it is. (Things didn't go to plan, and I managed to blend my bench slightly.)

Just so we're clear - don't try this one up your bum.

You make electronics fun. Thank you, Clive.

As always Clive, amusing, informative and brilliant.

Hey Clive, do you think its possible to hack the board and add a resistor in parallel to the motor sens resistor to allow it to not be so sensitive and parallel another 18650 so you had a longer usage between charges. I really like the features of that for when the my lady and I go camping.

"Whatever the fuck they are" BRILLIANT :-)

There's a position on the PCB for another parallel resistor. I suppose you could beef it up that way at the risk of it not detecting a stalled motor. There's not a huge amount of room for another cell inside, but you could top the unit up at any time with a power bank or solar panel.

Very nice explanation. Your circuit block diagrams really helpful in understanding for noobs like me. Oh that and the great humour! Thank you.

Looks quite good!
