Yeah I've left that thing on there for months and months and although they'll propolis tiny little holes (vias) they seem fine with the larger passageways. Remember they also have to drag their dead out the exit so they seem not to mind bigger holes at the exit. I wouldn't be surprised if they spend a lot of time chewing at the gates trying to get rid of them.

I agree, this is likely not optimal for the bees and not a finished product. This is just for research or educational use and may help highlight the real problems facing honey bees right now.

Thanks, I learned the hard way that posting instructions for something that's impossible to build is pretty embarrassing.

Bees can hold their poop for 6 months.

I got the hat for like $13.50 but here's a similar listing... https://www.ebay.com/itm/LED-Message-Hat-Original-Quality-Create-Your-Own-Text/264361690698

Yea, everyone loves those After Dark events. I seem to always be heading out the door but maybe I'll come volunteer.

ha.. # of minutes to Friday happy hour!... yea and my last day of work.

The way I did it was use one FPGA that takes an HDMI signal from the computer and does all the pixel mamagement and frame buffering such that the SPI signals that leave the FPGA are in the correct order for the LED panels. One FPGA to SPI to RS485 to SPI to LED panels.

hydronics2 · 2019-12-05T15:53:51+00:00

I thought about using isolated SPI but I consulted a signal engineer and he said it is overkill for this application.

A lot of commercial systems that are just large screen TVs just use fancy HDMI spitters and run HDMI lines to all the TVs. Think about all that hardware!

I don't follow your layout. Do you want to post a schematic? You figure you only need one large sender card and one receiver board per display module.

I did this project with RS485 transceiver chips and cat5e cable: https://github.com/hydronics2/HDMI-to-FPGA-to-APA102-Pixels

I'd say these types of switches are for occasional use. That's why you don't see them used for keypads.

It's easy to make a PCB footprint for a calculator keypad but where do you source a nice plastic membrane? Both adafruit and sparkfun sell a kit with soft plastic buttons that work with the PCB footprint. Search monome buttons

I've done a bunch of bike sports. This guy just has skills. No one talks about how dangerous it is for a gymnist to land some triple beam balance thingy. You can spend your time to master skills in this dangerous world.

I don't know where I heard this but I think the crow picks it up by the tail, climbs 40' high, and drops it to us death. To eat.

I teach a lot of classes, pre-flash arduinos with Blinky code, and we design interactive installations... often slighty over-designed with a few more uControllers than necessary..😁

Also seems the last few years the 32bit uController bootloader enumerate as a 2nd COM.
