- 300W dissipation minimum
- Multiple impedance taps - 2,4,8,16 ohm
- Is it best to buy more lower watt resistors and spread them out or is it best to buy fewer larger ones?
Don't Goop Your Electronics
- Don't try to obscure your design by putting smoo all over your PCB assembly
- Your schematic and board layout are not your trade secrets
Golf Cart Project

New Years Engineering Resolutions
- Parker
- Finish the Cat Feeder Unreminder
- Get the 65’ Checker “Running”
- Get to 200 lbs
- Stephen
- Smaller but more directed action
- Stretch resolution
- Be more present
- Practice more
- From the MacroFab Engineering Team
- Run DRC on your designs!
- We have DRC files for Eagle and Altium
- Questions about our DRC can be directed to [email protected]
- Cheating the DRC just results in more end cost due to infield failures and extra loss in E-testing
- From the WMD team
- Let us cheat the numbers not you
- The numbers are there for a reason. We know when we can fudge them.
- Podcast Resolutions
- Release podcast at Friday noon
- Going to video and the edits will be on Youtube
- Transcribing the audio
- More polls and user engagement
- Swag to give out during live streams

- Anti-gravity, repulsors (floating stuff)
- Vehicles are the obvious cool application

- The heat from the hot iron and the refractory sand constantly wore down the bearings in the conveyor system
- If things could just float it would be amazing
- Droids
- How does anyone actually program these?
- In The Mandalorian it seemed like it wasn’t a simple task to reprogram IG-11
- Anakin “built” C3PO but did he really build it or assemble it?
- In the series they say to “wipe the protocol droid’s memory” it seems like whatever the tech is it is easy to wipe memory but not easy to change programming

The Big Misconception About Electricity
Veritasium- YouTube video
- Is this really a big hidden secret?
- There is nothing incorrect but...
- Problems with the explanation
- Lack of context
- Doesn't go far enough on the explanation and would leave new hobbyist asking more questions then it answered
- Light bulb question at the beginning of the video
- How long does it take for a light bulb to turn on if the wires connecting it are a light-second long.
- Parker's quick "practical" answe
- “Instant” You are pushing the already existing electrons in the wire. An electron doesn't have to flow all the way around?
- Dave Jones' response?
- Does this damage Veritasium's image for Electrical engineers?
