We’ve all likely seen the amazing images possible with a scanning electron microscope. An SEM can yield remarkably detailed 3D images of the tiniest structures, and they can be invaluable tools for research. But blasting high-energy cathode rays onto metal-coated samples in the vacuum chamber of a bulky and expensive instrument isn’t the only way […]

In optical microscopes, there is a fundamental trade-off between field-of-view and resolution: the finer the detail, the smaller the region imaged by the microscope. One way to overcome this limitation is to translate the sample and acquire images over a larger field-of-view. The basic idea is to stitch together many high resolution images to form
Alright so soldering is pretty straightforward for through-hole components, but then there are times when you need to go tiny *insert ant-man reference here*, and the skills you learnt for TH soldering just dont apply anymore.Welcome to the world of Surface Mount Device (SMD) soldering, where components are placed on tiny pads, and solder on

For this first edition of the hardware teardown, we’re dissecting technology and lifestyle brand Withings’ cheapest activity and sleep tracker: the Withings GO.  Since they launched their first connected weighing scale back in 2010 (the WiFi Body Scale), I’ve been a big fan of Withings. They make beautiful products that integrate seamlessly with their online
I’d like to share my latest project, a scanning laser microscope with you. Some words concerning the principle: The pinciple is quite simple. The laser beam is focused on the object and the reflective light is being measured with a photodiode (in my case a BPW34). To focus right the current through the focusing coil
HOUSTON – (July 12, 2017) – Rice University engineers are building a flat microscope, called FlatScope TM, and developing software that can decode and trigger neurons on the surface of the brain. Their goal as part of a new government initiative is to provide an alternate path for sight and sound to be delivered directly
Flat microscope for the brain could help restore lost eyesight Continue Reading
Smartphone microscope as the name implies is basically a microscope which is compatible with a user’s smartphone. They mostly made up of a soft pliable lens and uses the smartphone’s camera. Smartphone microscopes have been in existence before, they are based on the use of external LEDs and usually get powered from an external source, these attachments

Remember the old video game Space Invaders? Some of its sound effects were provided by a chip called the 76477 Complex Sound Generation chip. While the sound effects1 produced by this 1978 chip seem primitive today, it was used in many video games, pinball games. But what’s inside this chip and how does it work
Reverse engineering the 76477 sound effect chip Continue Reading
At the risk of putting too fine a point on it, Hackaday exists because people are out there building and documenting open source gadgets. If the person who built a particular gizmo is willing to show the world how they did it, consider us interested. Since you’re reading this, we’ll assume you are as well.
Despite how good microscope you have, stand is still very important part of final assembly. And while there are many commercial ones made of cast iron, they might cost more than a microscope head itself. I decided to make stand from wildly available material laying around – it’s MDF (Medium Density Fiberboard). Advantages – stable
