Faced with an old console stereo from the 1960s that was barely functional, [Sherman Banks] aka W4ATL decided to upgrade its guts while keeping its appearance as close to the original as possible. This stereo set is a piece of mahogany furniture containing an AM/FM stereo receiver and an automatic turntable from JCPenny’s Penncrest line. As best [Sherman] can […]
Underscoring how far semiconductor makers have come during the pandemic, Xilinx, Intel and Lattice all announced releases of their largest field-programmable gate array (FPGA) platforms to date, and newer platforms with higher I/O count, memory bandwidth and transceiver bandwidth are sure to follow. Terabit bandwidths used to be unheard of, but today’s data center grade

Makers and hobbyists looking for a more substantial portable battery pack that they can make themselves, should check out this excellent DIY power bank created by Instructables user “tobychui”. Using an Arduino Nano board together with a 2.2 inch UART HMI display the batteries can provide up to 60w of power output. Fitted with a 4S (14.8v) Lithium Ion battery in the form of four Panasonic

The official Arduino team has today announced the availability of a new learning resource for those looking to learn more about creating projects using Arduino via the new cloud.arduino.cc website. If you’re teaching electronics or Arduino-based learning you’ll be pleased to know there are lots of projects and instructions on how to get your smart projects connected

Over on Hackaday.io, user [Tomasz Jastrzebski] has designed a tidy-looking custom controller for driving temperature-controlled soldering irons. The design is intended to be general purpose, capable of operating with irons rated for different voltages and probe type, be they thermocouple- or thermistor-based. Rather than integrating a power supply, this is handled by an external unit, giving

One of the biggest reasons for playing older video games on original hardware is that emulators and modern controllers can’t replicate the exact feel of how those games would have been originally experienced. This is true of old PC games as well, so if you want to use your original Sidewinder steering wheel or antique
We’ve often heard it said that springs come in in all shapes and sizes…except for the one you need. In light of this, the hardware hacker would do well to keep the tools and knowledge required to make a custom spring close at hand when building something that moves. Luckily, all it really take is
Lightning is a force to be reckoned with: ever since ancient times, humans have been in awe of the lethal power of lightning strikes and the deafening roar of thunder. Quite reasonably, they ascribed these events to acts of angry gods; today, modern science provides a more down-to-earth explanation of the physics involved, and a

Browsing through the recent projects on Hackaday.io, we’ve found this entry by [NanoCodeBug]: a single-PCB low-power trinket reviving the “pocket pet” concept while having some fun in the process! Some serious thought was put into making this device be as low-power as possible – with a gorgeous Sharp memory LCD and a low-power-friendly SAMD21, it can run
One of the joys of being a Maker and Hacker is solving problems and filling needs. When you can do both, well, that’s something special. [rodrigo.mejiasz]’s project surely fits into that special category of solving a problem and filling a dire need with his Bedridden Patient Monitor. While [Rodrigo]’s project page does not specify his motivation
