@froch_ @ScarbsTech Teams use the unloaded rollout to sort tire sets. Rolling radius is very important too.

@ToddMory @ScarbsTech That’s free rolling radius, what is the benefit of having it precisely ? I would assume the rolling radius with some load applied on the tire would be more interesting

Techmor and First Turn Innovations made a Rollout Arm tool to measure race tire circumference (rollout). The demo is on a NASCAR Cup Goodyear Tire on a BBS rim.

@TStrunk33 We don't have pricing yet. TBD soon. We just keep making it better everyday. Need to shoot the engineer and ship it! 🙂

@ToddMory That is awesome Todd. How much?

@coltonblack Digikey is slow at processing orders right now. It took 5 days for them to ship my order of 2 parts from stock. We are told they have record-level volumes and are struggling to keep up.

the PCBs ended up beating the digikey order by a day. that is after the PCBs went from Shenzhen to China then UPS delayed by 1 day to me. wow

@VishakhRanotra The most difficult problem is deciding which project to work on.

What are the most difficult problems to solve in engineering?

If anyone gets stuck at the bottom of the racetrack, we know who to call.

@gak_pdx When it comes to presses, that's the good Schmidt!

Decent eBay score for a small Schmidt press. Ever use an arbor press? Ever be frustrated with how shitty it is? German made Schmidt presses are like an arbor press, but everything is adjustable and the build quality is… German.

@ScarbsTech @FIAFormulaE Those German cars are not designed for easy maintenance.

@FIAFormulaE car's run a front MGU. Here Porsche are urgently changing the unit on #PW94 car between Q and the race. Needing the steering rack, driveshafts, data, cooling and HV electrical connections out of the way first. #FEtech #MadridEprix

@joeltelling "Orange you glad I didn't say banana" knock-knock joke?

I’ve been working on something and it brings back something from before I was 3d printing. Here is a hint: 🍊 🍌

@CATIAManikin It's a feature!

Trying to explain that using only three mounting holes is actually better than four, because four can overconstrain the alignment of the assembly (I broke a tap in the fourth hole)

@MakeAugusta Are you talking about Mikey?

He was Rudy before he helped Frodo.

@VishakhRanotra Productivity Hack: Wire all of your power tools to be always on. Big time saver!

This is such a great hack! Definitely gonna try it. Looks completely safe too.

@ElecNotes Excellent Info!

Why are NPN transistors more widely used than NPN? While both NPN and PNP bipolar junction transistors (BJTs) are essential tools for engineers, NPN versions are significantly more popular. If you’ve spent any time looking at datasheets or schematics, you’ll notice they dominate the landscape. Based on insights from Electronics Notes, here are the three primary reasons why NPN is the go-to choice: 1. Faster Performance (Carrier Mobility) The biggest technical advantage comes down to physics. NPN transistors use electrons as their majority charge carriers, while PNP transistors rely on holes. • Electrons move much more freely and quickly through the crystal lattice of the silicon than holes do. • This higher "mobility" means NPN transistors can switch faster and provide better performance in high-frequency applications. 2. Standardized Negative Grounding In the world of electronics—from automotive systems to consumer gadgets—negative grounding has become the universal standard. • The polarity of NPN transistors is naturally compatible with negative ground configurations. • This makes them easier to integrate into standard circuit designs without needing complex power supply arrangements. 3. Lower Production Costs Manufacturing economics play a huge role. Most silicon-based components are most efficiently produced using large N-type silicon wafers. • Interestingly, producing a PNP transistor with equivalent performance to an NPN often requires nearly three times more surface area on the wafer. • Since wafer space is at a premium, this makes PNP transistors more expensive to manufacture, driving the industry toward the more cost-effective NPN alternative. The Bottom Line: While PNP transistors are still vital for specific tasks (like push-pull amplifiers or high-side switching), the NPN transistor's speed, compatibility, and cost-efficiency make it the undisputed heavyweight champion of the bipolar world. #Electronics #electroniccomponents #ElectricalEngineering #TechTips #Transistors #NPN #PNP #electronicsnotes

@willreil They keep calling and you just keep winning

China called again, they told me to stick to protoboards

@MakeAugusta Tantalum is the good stuff. Plus, it is rated for higher temps and much longer life than leaky soup aluminum can electrolytics.

I never seen this his comparison before. I always just trusted the datasheet. This makes a lot of sense.

@benheck Maybe it's doing Delivery Optimization where your PC serves updates to other Windows customers. Gotta love that.

I'd say my biggest issue with #Windows 11 is how it randomly updates a lot more than 10. My WFH PC I always have windows and apps open, then put it to sleep. When it wakes up with them closed, makes it obvious that it updated without warning. Must update during sleep even?

@webronen @mikerankin @IObrizio Looks like a Tetris nightmare.

@mikerankin @IObrizio Ok, I do not complain..

What nightmares are made of…

@ScarbsTech @WeAreRSGroup Fun fact: Temperature is widely considered the most measured physical quantity in the world.

Things you'll find on an #F1 engine. @WeAreRSGroup temperature straps, £1.83 each. #F1tech 📸 Martin Trenkler

@MakeAugusta Also great for removing unwanted tattoos

When I teach soldering, I describe the iron as two parts. The hot part and the not hot part. The not hot part is the handle. The hot part will melt your skin and leave a scar that will last longer than you’ve been alive (they’re usually 12-15 years old). It is 100% effective.

@MakeAugusta 5 or 6 more would have done the trick.
