Using an Interlink force-sensing resistor, the user can slide and tap on the surface of the device, where the switch would be in the older version, in order to control the device. An idea is to double-tap to switch between solder mode and power set mode....
The idea for this circuit came to my mind as a rough diagram back around October 5, 2018. I had been working on my #ColorChord - A Steampunk inspired creation project and sat back thinking about the relationship between the led bar and the CdS...
As winter started to show by shortening the amount of light coming though my windows, i realized that I was missing a crucial element on my work from home desk : a lamp !I had a quick look on what was commercially available but nothing caught my...
Background Flip dot displays are amazingly cool IMHO. There has been a lot of flip dot activity posted to Hackaday and elsewhere over the years. Larry Build's 3D PRINTED FLIP DOTS is just the latest example. While Larry's project involves creating...
In early days when mobile phones began to be popular their chargers was linear with 50 or 60Hz transformer and four diode rectifier. These transformers has a high series resistance (main is about 10 ohm) so the output voltage falls very quickly after...

Why?I felt sorrow to throw away the machine when it is in a good condition and it is also fun to develop and create embedded electronics. I really like programming of MCUs. Another reason is my father has horses and the machine will be used for washing...
Beginnings and purpose I created another soldering iron in the past and I've been improving the firmware ever since then. https://hackaday.io/project/94905-hakko-revenge This soldering station has the following sensors...
Purpose of this token This security token is intended to be used as a development platform for security applications. It is built around a LPC55Sxx chip and a SE050 secure element both from NXP.This token has the same form factor as the OpenSK tokenfrom...
The backlight is an electroluminescent panel which glows a nice cool blue color. Unfortunately when its off its kind of an ugly pinkish color, but why would you ever turn it off?Its controlled by a button on the left side of the calculator and powered...
The power supply is comprised of four stages:AC Mains to 390V DC converterCurrent limited 390V DC to 1950V DC converterHV Multiplier DriverHV MultiplierThe HV multiplier and it's driver are the core of the project. Together they convert the 1950V DC...
One of the reasons Bluetooth has such a poor reception range is that it is designed to be a local comms gateway rather than a network. It was given a very small cell size, mainly to prevent overspill from one house to another being as each cell was private.That...
