A user of the “new” version of the lamp has undertaken the heroic task of writing the Bluetooth code for controlling it! Here’s a sneak-peak:
Someone, I won’t mention any names here, practically coerced me into upgrading this little project a bit. Now there’s the option to add a bluetooth module (HC-05, JY-MCU “ZS-040”), which supports remote code upload, or a WiFi module (ESP8266-1) using … Continue reading
Not too long ago one of these darn IKEA LED lamps (200lm, 4.3W) broke down after very mild usage. Well… it has happened again! When I went into my bathroom one or two hours ago, I thought I was going … Continue reading
It has happened again! After about 2 years of very mild usage (bathroom mirror light), an average on-time of about 5-10 minutes per day, yet another of my many IKEA LED lamps has died. This time it was a 4.3W … Continue reading
This upgrade is based on the loved-by-everybody WS2812B intelligent RGB LED and works just fine with Adafruit’s NeoPixel library. The concept is – once again – rather simple. Whack a lot of WS2812B RGB LEDs onto a small board, add … Continue reading
Yet another reincarnation of a PT4115 based LED lamp. This time I chose to add a micro-controller to the mix. No, not an ATtiny13 but an ATtiny45, as it contains a much desired feature for this job: high frequency PWM … Continue reading
I bought this LED bulb about 21 months ago for €11.99. I liked it!
First the old version, using the best small LEDs I could get hold of at that time: Nichia NSSL157 and NSSW157 types driven at about 100mA.
Quite often I run into the problem of getting light to where I need it when inspecting SMD solder joints. The ring-light I built some time ago provides a lot of light, but is too large to get close to … Continue reading
My trusty Pentax S5z still works reliably. I’ve had it for 8 years now. It doesn’t shoot HD videos and it requires a couple of replacement batteries now and then, but it makes quite nice macro shots (with the help … Continue reading
… or will be ! It was at night, it was raining, ice rain at times, the roads were covered with slippery leaves. I met a lot of bikers – some of them had their lights on. I was still … Continue reading
