EXPERIMENTER'S GOODY BAGS

Contents will vary slightly because these bags contain factory surplus stock items as available.

Bag number 1 - ONLY 50p  each

Each bag contains about  15 ICs (including some 7400 series ICs).

 

Bag number 2 - ONLY 50p   each

Each bag contains about 100 resistors

Bag number 3 - ONLY 50p   each

Each bag contains about 50 capacitors (pF and nF values)

Bag number 4, REED RELAYS - ONLY 1   each

 

  Contains 4 assorted Reed Relays. Work well on 6 to 12 Volts. Use low current and will switch higher currents and voltages. Normally cost more than 2 each!

 

Random selection of SPST, SPNO, DPDT, DPST etc. Useful for experimentation.


PRIVATE SALES

I have available one only Mains voltage (220V to 250V) to 110V  500VA transformer. This was given to a friend to use for equipment he had brought back from the US.

He never used it because it is not encased and does not have appropriate leads and connectors.

I have found similar transformers with the same specification on the RAPID website for 75.

If anyone wants this for 20 you need to contact me via e-mail ( [email protected] ) to arrange collection and/or delivery. It weighs approx 8Kgs so would cost over 16 to post!
