I plan on giving updates on what I'm working on here, since I'm useless at writing blogs. I'm hoping i can stick to short regular updates.

Here's my cocktail machine. I'm currently writing the software for it!

Another project complete. 3D printed RC jetboat.

I haven't worked on the cocktail robot in a while, but i have been busy! I built a case full of a r-pi and radios and stuck it on my roof. It contributes to flightaware.com: https://imgur.com/a/xepw7x2

I am not above using kitchen consumables to make things work. #bbq #3dprinting

The next sign. Made for a friend who's into tonkas. Turns out the pink and red wire look similar when they're off. Whoops.

I love it when a plan comes together. A neon-esque sign from the bar in the movie "Cocktail".

This was made by 3D printing a frame and using it to shape el-wire.

Should this go on the cocktail robot or above my bar at home?

100 zipties.. Check
Epoxy all over my hands.. Check.

Hopefully this was worth it

Added event-based glass detection that controls the bottom set of LEDs. Then mucked around for an hour with multi-thread locking and misreading the library docs. Just for this..

I can only apologise for not thinking to do this the first time around. Why did i think a black, non-glowing platform was acceptable?

Got the loadcell functioning as a glass detector. There is just a weight threshold. It turns some lights bright white so you can see your glass 😁

Promise kept! Platform done.

Theres not many things in life that require you to google "splashless urinal mat", but now i have! Hopefully water dripping onto this platform wont splash too much. Plus it has drain holes in it to drain out under the machine 👍

The loadcell is mounted and a hole cut above it. Time to make the platform!

Man do my side projects move slowly!

I've 3d printed a mount for the loadcell, i just need to mount it, and then build a platform that will hold the glasses that is suspended by the loadcell. Hopefully i will get that done this weekend.

In the meantime I've started making a faux neon sign from the movie "Cocktail" 😂

I'm also making a 3D printed jet boat.

Replacing rfid scanner with a different one. New scanner and load cell using the existing cable due to UART using fewer pins than SPI.

@jmwright media uploads are failing again? Just trying to post a pic

Finally got my lego saturn V on the wall.

I'd like to take a moment to praise d-sub connectors (DB-25 etc). They're awesome. I'm surprised by the current they can handle every time I look it up. You can't connect them backwards and they're easy to solder to.

All of the motors on the Cocktailor are powered through a DB-25. A lot of my model planes have DB-9s in them to connect wings etc.

I've replaced the mfc522 card reader with a Pn532 (temporarily wired for now). The pn has a more mature library for it, and seems to solve the issue of cards being partially read.

It also uses fewer pins (UART vs SPI) and so I can wire up the loadcell using all existing wiring.

I think this graph is going to be really handy to troubleshoot calibration etc.

While I've been quiet the robot has hosted an after-work drinks session that went really well 😁
