High voltage power supply for Nixie tubes

Friday, April 8th, 2016

Limpkin has published a new build: a high voltage power supply for Nixie tubes For quite a while I've had this project idea in the back of my head that would involve using many Nixie tubes. These funny looking cold cathode displays were actually introduced during the 1950s and unfortunately...

A 1-meter-diameter small transmitting loop for 7 MHz, part 1

Friday, April 1st, 2016

qrp-gaijin has been working on a 1-meter-diameter small transmitting loop for 7 MHz: I've decided to try constructing a smaller, more traditional loop of 1-meter diameter. A smaller loop means smaller radiation resistance, and that means that small values of loss resistance become more significant. Great care must be taken in all...

Mains 230VAC isolator

Friday, March 25th, 2016

Jaanus Kalde has built an isolator box: Probing mains powered schematics is hard. Most oscilloscopes are earth referenced, so connecting ground probe to random spot of mains connected device will make a small explosion. Also there is the risk of electric shock by touching wrong part of the schematic while being in...

Building a simple circuit probe

Wednesday, March 23rd, 2016

Vicente Jiménez has published a new build: Sometimes you need to check one circuit and test some of its nodes. Usually a tester in voltage mode is a good solution, but it has a pair of problems. First, it measures about zero both when the node is driven at zero...

Night light 2.0, part II

Tuesday, February 11th, 2014

Kevin Rye built this Night Light 2.0: And there it is. Definitely not my best work, but it’ll do. I just wanted to use up that last PCB left over from the Tesseract build. I guess it was better to use the PCB for something rather than have it sitting in a parts...
