To be honest, I’m not looking forward to opening this letter… …but there is no way around it.
Not “pining for the fjords”, but pining for the boards!
Bought a cheap AVR-ISP programmer on Ebay, and you find out that while it does provide 3.3V, it is VCC-only & your device is NOT 5V tolerant on its I/O pins. BUMMER! This little board fixes just that issue. All … Continue reading
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:
Today, a Sunday, I discovered a letter in my mailbox. A LETTER FROM CUSTOMS – >> MAIN OFFICE
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 smell something… sniff sniff … yes, I smell BS!
These LEDs have been in use for about 3.5 years now. 28 out of 64 show discolouration. Fortunately these are used as a source of indirect light, bouncing off of a slightly yellow-ish wall. The effect is noticeable, but not … 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
For a couple of days now, the monitor doesn’t want to run on full brightness anymore. If I go up to 95%, it runs if warm, but might not start up. Set it to anything higher and it comes on … 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
Someone on the KiCad mailing list has created a windows installer of the BZR5025 code base, including libraries, demo projects, docs… I’ve mirrored it on my server for your convenience. KiCad downloads Please note that this version uses library-tables and … Continue reading
Don’t you just hate it when you run out of holes and have to use a bridge wire to some free patch on the proto-board? I thought so.
