I&#x27;d love if anyone can point me to community site for DIY Bio &#x2F; garage materials hacking.<p>I have an idea for a hobby project that involves building a robot to mix small amounts of (safe, non-biological) liquids... need to be able to dispense 0.1ml to 10ml range, but very precisely.<p>My current thinking is hooking up syringes with one way valves (one going to the supply, one going to the output) ... and a linear actuator or screw drive to move the plunger back and forth-- so on the pull stroke the syringe would fill from the reservoir and on the push stroke it would fill the output.<p>But I figure there might be an off the shelf solution for something like this that&#x27;s hacker friendly.
