The project has its roots in the SMD soldering station by Martin Kumm(http://www.martin-kumm.de/wiki/doku.php?id=Projects:SMD_Solderstation)Some years ago I got a tray full of ATMEGA168's and since then I've always wonderes why people made shields for...
First part of the system could be data collector of solar panels status.There are two possible solutions how to collect the data:1. Measure solar panels status directly.2. Use invertor data available on RS 485 interface. They use Modbus protocol.I prefer...
The issue was a dead left speaker. Everything else was fine. Curiously, it got back to life after poking on the speaker wires. But it died again after a few hours of use. From this behavior, I assumed that the speaker itself was not the problem. Instead,...
A gathering of people who like to create things. This event is not affiliated with any hackerspace, club, or even groups of friends. It is an attempt by one man(myself) to bring together like-minded folks and introduce them to the Hackaday community...
Accelerated lifetime testing will not be done to confirm that it slows degradation (I don't have a 5000 W water-cooled xenon lamp anyway). Instead I will just check the temperature of the panel / cell with and without the TEG, exposed to the same conditions....
There are a variety of inexpensive (<$100) 2 entry level near-field probes available from the usual suspects, however i've been dissuaded purchasing them for following reasons: fly by night operations: how long will this random ebay item be available?...
Curios continuedMaking the Nixie sockets was the ballest of ballaches but I’m not waiting around for an eastern European import at such a high price. That said, for other more popular tubes (IN-14 for example) it’s cheap. I just liked these big fat old...
I did this project to keep myself occupied while recovering from some surgery in 2015, for which I would have limited mobility for about a month. I didn't think I'd be up to doing bench work, so I used some existing PCBs to allow me to focus on the firmware,...
It's intended as an educational toy for my 2 year old son. The idea is that he plays with letters and numbers and eventually spelling and maybe even math.As mentioned above, there is a PS/2 keyboard attached to an ATMega328-P programmed using Arduino....
Cyclone separators are very simple and common devices in process engineering. In such a separator, centrifugal force is utilized to separate particles from the raw air, which is passed into the device tangentially. The cleaned air exits through a straight...
One predecessor of the #DIPSY is this Actel-based prototyping/OEM board.It may look trivial to build, but it uses the CN132 package of the Actel (Microsemi) ProASIC3 FPGA family. This is one of the worst packages: it is 3 row staggered QFN style package...

Sometimes size is crucial. If you need a hub for your workdesk, you can pick almost any of them and size is hardly the most important part - price and count of ports are more imortant. However, if you're going to embed a USB hub into something small,...
Fortunately I came across this great Hackaday page by Patrick! https://hackaday.io/project/9461-lifepo4weredpi He was nice enough to answer questions and help me with my design. My previous 2 layouts were failures, shutting down after only 4A! ...
This is a dust separator. We make it using two buckets : -one for the cyclone part, that we modify to add holes and parts,-one for the dust bin, that is unmodified.The idea is to reduce the amount of labor required to make a functionnal and sturdy cyclone.To...
