The first two are of my Philips Philetta from year 1967.

A CRT monitor built in 1966. When I managed the unit with about 25 kg after home, the mandatory cleaning. Then carefully first plugged into an outlet that ran something like wax from a suppression capacitor. Was so designed only for 220V (we have 230V now) and I do not know how long it was no longer in operation. After replacing them with 250 V voltage rating, it looks even better for the boob tube.:)

Almost 20 years ago this world receiver one of my most expensive purchase with about 470 DM was It is the version with full 150-29995 kHz (LW, MW, SW) and 76-108 MHz (VHF extended). Some time ago, I need to change a few dried out capacitors.

EPROM-Programmer for EP-ROMs 16 to 256 Kbit.

EPROM-Programmer for (E)EP-ROMs 16 KBit to 1 MBit.

My good old oscilloscope.

Videorecorder System Video 2000, Year 1986 (?).

2 Videorecorder System Video 2000, Years 1979 & 1984 (?).

Analog Decoder for Premiere incl key card, built: 1990(?).

Test pattern generator PAL with 75 ohm video, VHF and UHF outputs, Built in 1974/1975.

This beautiful device called Digital Tape Analyzer. A Z-80 system displays hours, minutes, seconds and frames on 7-segment displays. I'm sure no suitable device and can not find pinouts of the rear jacks.

An electronic typewriter, built in 1984 Nearly a computer.; the CPU has an IBM house number on it, so do not know exactly what it is for one.

This is a mobile TV-Radio-Set from year 1968. With 10,5 cm BW-Screen and a lot of japan germanium transistors.

bekame defektive !

A signal level meter from WISI (Wilhelm Sihn), it´s 40 years old. Receiver for Radio FM, TV VHF I / II and UHF.
Bekame with a few cables in a metal suitcase.

My first ones is the SmartKit Electronics 1045. A Soundgenerator.

A Sound-Sampler for AMIGA.

8-channel-relaisinterface for parallelport.

Mono FM tranceiver 80 - 108 MHz with 5 W output.

This is a VLF-Fax-receiver for the very long wave band of 75 - 150 kHz.

FSK-/RTTY-decoder for a serielle computerport.

A VHF-/UHF-Tuner with Nf-amplifier and tone change over switch. It has antennas -, headphones- and AV- connection. The power pack is a ringcoretransformer with 14 volt.

12 volt stereoamplifier.

From a friend I got this old desktop device of Schneider (record player was defective) and built it into a plexiglass casing with bulbs and IR switches.

In an old housing of a cassette deck I built a tube preamplifier. The used tubes are two ECC 83 and two EL 84. I took over the switches, buttons and controlling announcement (fluorescent meter) from the cassette deck.
In the meantime I converted the tube preamplifier to a full amplifier. For the connection to two 4 or 8 ohm loudspeakers I inserted two new transducers, as well as a new supplytransformer with more power. Instead of recording level indicator now a "magic band" (type PM 84) is in it. Here it gives my connection diagram of the tube amplifier: Konzertmeister 2000.FH8 or

A Tubesynthesizer with soundgenerators, bassbooster und vibrator. Sheets from my "Musimoog":

WIP: Built the synthesizer in a 19"-Case with more tubes.

Different supplies .

Low Power "lightart" with 18 Low-Current-LED´s on a solarpanel with 12 VDC.

In a 19"-case I have a analogsynthesizer built in. There´s in now from left to right: Supply +- 5 / +- 15 volt, VCO (sawtooth right up), LFO (tri- , rectangel right middle), white-/ pink-noise, PWM with NE 556 and sequencer with CMOS.

The sheets here: Analogsynth

After I still another a ring modulator and filter had inserted, the front plate became quite full.
In the photo left down one sees the synthesizer between the tubesynthesizer and a function table with rectangle/sine signal. Right down individually.

A videotest-picturegenerator with an Atmel ATMega 8.

This videoterminal with an ATMega 8 can ASCII-Fonts over RS232 put in and on a monitor with cvbs out.

An AVR controllerboard namend K-Module with ISP-adapter and LCD-module.

Another "lightart" of 8 SMD-RGB-LED´s on an acrylglasring, it works with an ATTiny 2313 SMD.

And a another "lightart". Flower of wires and sheets made it. The head is a big yellow LED, a green on a leaf and a red in a CD-box as bottom. The program to blinking is in an ATTiny 13.

A CCFL-Tube with 9V-battery or powersupply.

On the fly for Christmas 2011 finished buildings with my mother star with 36 red square LED's.

In May 2012, I got two puzzle pieces made ​​of platinum residues given. On one I could build a small turn signals.

Also on analog oscilloscopes can display a clock. :) Creates she is from an AVR Clock V2.7 of Dutchtronix. At the resolution you would still screw something, but is only a gimmick.

Selfmade cottage with a purchased RGB LED lamp and IR remote control. To this end, I would just need a guard dog. :)

An ATMEGA48 control FETs BUZ90. On the slopes, the 5 24-volt lamps of the traffic lights. The lighting effects should be selectable by pressing a key.
