Franks Electron tube Pages

“At the age of 10 we moved to Copenhagen for about 2 years. I had some friends there who knew that I liked old radios so regularly someone brought me one. (See my picture at the main page) Among them was the Bang & Olufsen – Grand Prix 48 K (photo). I liked this radio so much that I wanted to make it work again. There was not much wrong so I got it working. Later when we were back in Eindhoven, I made so many …….”

The tube data resides on several mirror sites in several countries and they are exactly equal, except for the Poland site which additionally has been equipped with a tube search.

More about Frank’s Experiments

“Back in Eindhoven, there where the 60’s. Radio Luxembourg on my B&O etc. I got interest in guitars and amplifiers. I built several Amps. My first amp was something with the EF11 and the EL3. I also built a copy of the Philips EL6431 Amplifier. (That’s where the output transformer of my B&O radio went) In Eindhoven there was a repair shop called ‘De Radiodokter’. He had some old TV chassis in the display for 5 guilders each. When I had saved enough money, I bought some. Then when I was about 16 I made my first really working TV from these parts.”

DMX Motor Controller - Blue Point Engineering

The DMX- (Servo) Motor controller allows DC motors to be controlled over a standard DMX system. The board may be configure to drive the DC motor simply as a variable speed, reversible motor or with the addition of a position feed back potentiometer, to create a powerful servo motor controller for accurate positioning purposes.

Auto Fill Circuit for Laser Cooling Loop – Ethernet Data Logging

Here is an automation solution with a ethernet usage. The code and diagrams are also there. This is something that covers many aspects of engineering in one project. Try such things out to learn, only after you have mastered the basics.

“The Ethernet connection is based on an XPORT form Lantronics. Basically it lets you use a serial port to send things over Ethernet. A PIC microcontroller with an A/D converter digitizes the pressure, the pressure set point, the high and low pressure alarm points and the supply voltage (since everything is ratio-metric). “

BeagleBot – Beagle powered robot

“For measuring distances I chose to use SRF08. It is an ultrasonic ranger with I2C bus and measure range from 3 cm to 6 m. The sensor has a beam width of 55 degrees (-6 dB points) and when mounted on top of one of the servos it can be used for covering well over 180 degrees.”

BeagleBot – Beagle powered robot – A small experimental robot with Beagle Board as it’s heart.

Servo System -Double Hitec HS-422 servos mounted on a special two axis brackets. – 5 pcs of normal RC servos with 50 Hz PWM control. ATMega16 at the expansion board creates the PWM for all of the servos and provides an I2C control interface for them. User space application running on beagle board can thus control the servos just sending only a simple I2C message.

The Course – “We start with a few lessons about voltage, current en resistance. Next, we’ll discuss power dissipation and capacitors, diodes and transistors. We now have enough knowlegdge to build a simple power supply. And after a few lessons about differential amplifiers and operational amplifiers, we are even able to design and build a professional lab power supply.”

Thomas Driemeyer – Bicycle Guide

“I often get asked about bicycle maintenance and repairs, and tips for how to ride efficiently. This little manual is intended as a summary of what I have learned over the years. I am not a professional mechanic.

Thomas Driemeyer – Bicycle Guide

All of what I say here is the result of personal experience and opinion and may in places flatly contradict professional techniques, but it has served me well. I offer no guarantees that it will work for you. If your bicycle falls apart because I said something wrong, you are on your own.” – Thomas Driemeyer .

Computer-controlled LED lamp

Computer-controlled LED lamp

This page shows how to build a lamp using this module that can be programmed to show any color or cycle of colors, as instructed by a PC or Mac over a serial RS232 line. (Or USB, using a cheap USB-to-serial adapter – unfortunately USB cables cannot be longer than about two meters before they become either unreliable or very expensive.)
