DollaTek ICL8038 Hoge Precisie Signaal Generator DIY Kit Sinus Driehoek Vierkante Zaagtand Output 5Hz ~ 400 kHz Verstelbare Frequentie Amplitude

Alles ein wenig fummelig, Signalform für Bastelarbeiten akzeptabel, wenn man das Ding öfters braucht, ist es besser, Umschalter einzubauen, das ewige Umstecken der Jumper ist nervig.

As the data says, easy to build.Sine wave is a bit dodgy, but it didn't matter for my application.Good value

I purchased this for fun, plus being able to use it as a signal generator. I reduced the stars due to NOT receiving assembly instructions. I was able to get help from the web, which I am not allowed to post here due to Amazon’s strict policy. Which I find strange, because with a goo review, more of these would be sold, anyways, I digress. I found instructions, and printed the parts page, page 8, and printed it out. All of the components were listed except resistor 17, and since I only had one left, it had to be it.After printing page 8, I used a magnifying glass to identify the capacitors, and stuck the pins through the paper sheet, next to the proper identification number. I checked all of the resistors with an Ohm meter, and placed them on the board.Once I was done, I powered it up, connected it to an oscilloscope, and viola, it worked. Pretty cool too. The sine wave is a bit funky, but the square wave and triangle wave are awesome. I really wish I could share the URL to the sight, for the instructables, but a little searching and you’ll find it.Oh, one last thing, you will need a capacitor code chart, to identify the capacitor value, it’s not hard, and If I can do it, so can you too, GOOD LUCK!!!

Matériel livré sans notice de montage et le pire, sans nomenclature. On ne sait pas ou placer les résistances et condensateurs céramiques avec aucunes indications des valeurs sur le circuit imprimé. J'ai passé beaucoup de temps en recherche sur Internet pour trouver des explications. Mais on ne trouve pas vraiment les mêmes circuits. Résultat, le montage ne fonctionne pas.A déconseiller fortement au débutants ! Les kits sont censés être faciles à monter pour des débutants et là c'est loin d'être le cas.12,99Euros à mettre à la poubelle.
