Thanks for the kind words! Nimbus was a really fun project, just spent a bit re-formatting previous writeups to be more modern-web compliant. The one-wheel was indeed a weirdly synchronous release, I had no idea it would be as wildly successful as it became.

transistor-manon Show HN: I made Gyroscopic Gyro Sandwiches

It does indeed work! I've been meaning to instrument a food stimulant mass to determine how the chaos is effected my mass offset vs speed. I think due to the under-actuated nature of the system you're stuck with a balance between cg-offset, gravity and input rotation on the first axis

Admittedly this is a play on words, fair point! Gimbaled Gyro Sandwiches would be a better title

Have you noticed that a gyro sandwich is only cooked in one axis?

I built a contraption to slow cook in multiple axes and documented it here:

Not only is it tasty, it's mesmerizing to watch. Feel free to copy the design for your own festivities.

transistor-manon 1990s Millport CNC Vertical Mill Revival

It's always nice to see a detailed write up, a lot of cnc mill repairs end up replacing the existing control hardware but this write up was a curious take on maintaining the existing electronics, which takes more talent than replacing.

transistor-manon DIY Adapter: Using an e-bike battery to run a laptop

Thanks for the question, I completely missed that part. I'm using a homemade e-bike where the battery is just connected with a standard Anderson connector. A lot of off the shelf battery modules do have proprietary connectors, but a fair number have been documented. The M365 scooter batteries for instance are 36V 9AH and they connect with a hobby XT series connector.

At 80W, running a laptop, it hovered around 90F, shown here: https://transistor-man.com/lenovo_ebike_adapter.html#How_doe...

This is excellent, wait does this actually work

transistor-manon DIY Adapter: Using an e-bike battery to run a laptop

Woah that comment is a call back, thanks for digging it up.

I think one of the major boundary conditions, aside from 25V caps are just thermal. Laptops can't really radiate more than 100W continuously, and 20V at 5A is a fairly happy balance of wire thickness (defined by current rating) and system battery voltage defined by battery chemistry. A 4-cell lithium string tops out at 16v, and a 20v to 16v dc/dc is marginally smaller than a 60v to 16v dc/dc

transistor-manon DIY Adapter: Using an e-bike battery to run a laptop

There's definitely ways to shrink this down and I tried to address that in the initial DC-DC selection. The minimum supply that certain P-Series Lenovos require is 135W, while this module is rated for 150W, it is available surplus for relatively cheap (40$) without requiring building a full enclosure.

Looking forward to taking a second pass at this and shrinking it down.

at the moment it's somewhat smaller than the stock 'brick':

transistor-manon DIY Adapter: Using an e-bike battery to run a laptop

That is so refreshing, yeah the lenovo P series just ignores USB-PD inputs as it nominally wants 135W external power minimum. The kicker is it rarely ever draws more than 90w

transistor-manon DIY Adapter: Using an e-bike battery to run a laptop

I really enjoy working remotely, like properly out in the woods. For whatever reason most of the 'desktop replacement' laptops refuse to use external USB-PD battery banks so I designed a quick in-line adapter around an industrial DC/DC converter. Its fairly quick to assemble and thought this might be of interest to some of you.

I've been using it as a mixed place for documenting engineering projects and hosting piles of images from various reverse engineering efforts & excursions throughout the states.

I've been slowly working on it becoming more mobile friendly. As a static site its incredibly time consuming to cleanup, but also fun. It's like restoring up rusty cookware, similar functionality but way prettier after a lot of scrubbing.

transistor-manon 10mbps over 1km on a single pair of wires

Any chance you're going to release schematics / open source the design?

transistor-manon 10mbps over 1km on a single pair of wires

Awesome project!

This would be fairly great fit for underwater UAV's, or like security camera way out on the edge of property. May be a good idea to post on ardu-sub related discussion forums. I'm not aware of an off the shelf module that's point to point ADSL, almost every modem is intended to yell at a ADSL / ADSL2+ host.

Did you run into any issues with consumer-grade gigabit switches negotiating 10Mbit?
