Design and validation of a #frugal, #automated, #OpenSource solid-phase #peptide #synthesizer (#SPPS):

-#Raspi/#Python-controlled
-hardware cost: US $300 to $600
-yield: µmoles of peptide at a cost of ~$1/residue

I have a raspberry pi-controlled analog TV signal transmitter I use to send video to my small collection of small TVs.

TVs: Sony TV-413, Panasonic TRG-513T
Transmitter: raspi + hackrf + hacktv

Any of my Cincy friends have a Canon EF 100mm f/2.8 Macro USM lens that I could borrow?

Will be used indoors under very controlled conditions. I want to see how it will work as a digital microscope lens when paired with a Pinefeat adaptor to the RasPi High Quality Camera sensor.

some kid's toy unexpectedly controlled by a raspi?
(i assume it keeps coming back)

• All the IO peripherals!! The RP2350 on its own is a powerhouse. But I've also included up to 8MB (64 Mbit) onboard flash, a MOSFET-controlled output for an LED/buzzer/vibration motor, SWD header compatible with the RasPi Debug Probe, and an adorably small Seeed WIO-SX1262 LoRa radio module.

The goal is to have this as a low cost microscope that uses:
-RasPi
-HQ image sensor
-PineFeat adaptor
-Canon macro lenses for optics
-XYZ that is motorized controlled through an interface

Why not reprogramming a Roomba motors using a Raspi and some python, expose them via a web socked, so it can be controlled using a phone’s pad? www.youtube.com/watch?v=mTpk...

Still to-do: 1/4 wave dipole or monopole for airband. #gpiolabs airband filter, LNA and bias-t up in a mast. RasPi controlled relay to switch bias-t and USB-hub off, if necessary!

Later #acarsdeco2 and dumpvdl2 will feed ACARS my private server, @VRadarServer already running.
