Even though Texas Instruments were the first company to produce an integrated circuit and a microprocessor, their success as a company in the 60s and 70s was not guaranteed. At …read more Continue reading Upgrading At Least One Component of a TI Calculator
We all know that solderless breadboards have their limitations. All that stray capacitance can play hell with circuits, especially high-speed stuff, but they’re so darn useful that avoiding them in …read more Continue reading Switching Converter for EEPROM Programmer Taxes Solderless Breadboard
When it comes to powering tiny devices for a long time, coin cell batteries are the battery of choice for things like keyfobs, watches, and even some IoT devices. They’re …read more Continue reading Minimizing Stress on a Coin Cell Battery
If you’re an experienced hacker, you’ve probably run into a problem at some point and thought “let’s make a tool to automate that”. A few hours later you’ve got your …read more Continue reading A Neat Little Tool to Reset the Fuses on Your ATtiny
Supercapacitors are definitely not the same as batteries, we all know that. They tend to have a very low operating voltage, and due to their operating principle of storing charge …read more Continue reading SuperCapacitors vs Batteries Again
Most makerspaces and hackerspaces have one night per week or month where the ‘space is open to the public in order to entice new people into joining up. Whereas most …read more Continue reading Scrolling Name Badge Is Sure to Break the Ice
There comes a time in every hardware hacker’s career during which they first realize they need a negative voltage rail in their project. There also comes a time, usually ~10ms …read more Continue reading Quick and (Not Very) Dirty Negative Voltage Supply
Call us old fashioned, but we feel like when you buy a piece of hardware, the thing should actually function. Now don’t get us wrong, like most of you, we’re …read more Continue reading Investigating a Defective USB Power Bank Module
One of the easiest ways to get into hardware hacking is by piecing together a few modules and shoehorning them into a really cool home. For example, why buy a commercial moon lamp when you can spend 30+ hours printing …read more

[SM6VFZ] designed, built and tested a switched-mode DC-DC boost regulator using the core independent peripherals (CIP) of an ATtiny214 micro-controller as a proof of concept, and it looks pretty promising!
A Buck, Boost, or Buck-Boost switching regulator topology usually consists of a diode, a switching element (MOSFET) and an energy …read more
