A cheap toaster these days will use a toaster ASIC rather than a general purpose microcontroller or timer. PT8A2514 [1] is one example. Another surprising type of ASICs I've come across are vape ASICS [2]. [1]:…
Starlink for RVs: $135/month. A premium over the standard product, but far less than $500/month for business service. https://www.starlink.com/rv
I built a USB power back using these cells a couple months ago after finding out that disposable vapes have rechargeable batteries. A friend had already taken the cells out of several of his own vapes; I don't know how…
Using multiple events for a single bit seemed pretty inefficient to me when I built a random number generator based on radioactive decay [0]. I ended up toggling a bit every time an ADC was sampled. When an event was…
While impractical and not cost effective, having a bunch of bikes connected to the grid and randomly producing power would have no more of an impact on the grid than flicking a 60W light bulb on and off.
We may be seeing the highest nominal price for wheat in US history, but we are nowhere near the highest inflation adjusted price. The price of wheat in 1866 was $2.06/bu [0]. That is $36.43/bu in 2022 prices. In times…
These MOT based spot welders transfer far more heat to cells than capacitive discharge welders. This can result in the damage to heat sensitive components inside the cells which is the same reason that soldering isn't…
