My latest in driving down cost in DIY lab automation: a redesigned pipette drive, which can work with an Ender 3 printer frame, a Jubilee frame or anything else you want to mount it to. Uses a linear stepper motor to drive the pipette piston and retains the tip ejector mechanism.
The original design (top) had a BOM of $300. This one (bottom) is closer to $30 and can work with a range of cheap but good pipettes from OniLAB that you can buy on Amazon

Seeing a lot of quotes about Starlink… how do I tell them that the Starlink in the heli wasn’t working at all and this is all cellular. Radio has crazy range when there’s nothing to obstruct it 🙂↕️
@EngineeredAf Instead of hopping between mm, cm or m just choose 1 to think in (imo, cm for casual convo, mm for design) as a start because when you're comfortable, its just a matter of scaling by powers of 10. If you need precision just use a tool. No issue
@EngineeredAf From the Caribbean (& in Canada) so I've used both all my life & I've found you kinda use each system depending on the context really. Metric is useful for accuracy & calculation, SAE for large distances & everything else. That said, if you're mainly after distances 2/
I could ask for nothing beyond the tastefulness of its appearance.
I request nothing more than its strength, durability, and conductivity.
I have great confidence for which there can be no price.
In Beryllium Copper, I have what I need.
@muhasaba_needer I went to a technical HS & worked a bit so I have an idea as to what's what but it's no surprise the avg. student/grad can't tell the diff. between an endmill & twistdrill blindly. My search for old books is to supplement my learning till I can do better
@muhasaba_needer Don't get me started lol. I chose my school bcuz they're one of the few that offers Man. Eng. as a BEng & they'd rather have the machines collect dust and rust than offer my tiny cohort shop time. The most I've done is manually write gcode to turn a part I couldn't keep. 1/
@muhasaba_needer The closest books I've come across in my classes are: Boothroyd below (more for the designer) & Groover (more for a factory/prod. system planner). Both definitely get you in the frame of mind and ballpark but with the slight exception of Boothroyd, it's mostly theory
