Have not used it a lot but seems to work well enough for what I'm doing with it

First, I love kits. This was a quick and easy build, and delivers the signals advertised. If it just came with a case, It would merit a 5 star review.

It would be cool if they offered an enclosure but the bottom line is it does exactly what it says and for a decent price. I was especially pleased that they gave me more pin headers than needed since I used one pair for a sort of power switch so I didn't have to constantly remove and replace the battery.

Easy to build and works great for a cheap signal generator

Hard to beat for the money, a very good basic function generator kit. My kit was short one resistor value (but fortunately I had a replacement), otherwise a 5 star rating. The kit went together well, although I would have chosen a slightly different order of parts placement. After assembly, the kit worked well. I checked all functions on my Tek O'scope. Right on the mark with no distortion. I plan on placing it in a project box and adding output jacks, an on/off switch, etc.

Ich brauchte einen einen einfachen Sinusgenerator. Klar, kann ich den auch selber bauen, aber weder für den Preis, noch in der Kompaktheit.Wichtig war mir auch, dass der an einer einfachen 9V Batterie läuft.Aufbau:Hier kann man nichts falsch machen, den Aufbau würden auch Lötanfänger in kurzer Zeit hinbekommen, da die Lötaugen sehr groß und in weitem Abstand sind. Das Löten hat bei mir nur 30 Minuten gedauert.Die Anleitung ist super detailreich bebildert, ich würde lediglich die Jumper J1-J4 als erstes löten, da man die dann auf ein Breadboard stecken kann. So ist etwas friemelig, aber machbar.Wenn ich es nochmal bauen würde, dann würde ich* den IC 555 nicht sockeln,* die Elkos liegen löten, Platz ist genug da und* die GND und OUT Pins durch Buchsen ersetzen. Dadurch läßt sich das Signal leichter abgreifen und via Steckbrücke auf seine Schaltung bringen. So wird die Bauhöhe nicht so groß und es läßt sich leicher ein Plexiglasgehäuse bauen.Zu Qualität des Signales:Ich brauchte nur einen Sinus, den habe ich mal fotografiert.Ich denke das Bild spricht für sich. Mehr kann man für einen solchen Preis nicht erwarten, ist aber für mich mehr als brauchbar.Das Signal soll nur als Test für ein anderes Projekt dienen.Fazit: Klare 5 Sterne.Und: Ich habe den Bausatz selber bezahlt und nicht verbilligt/geschenkt bekommen, also völlig Unvoreingenommen.

Built this in an evening and it works brilliantly. The sine wave on a scope is pretty pure and the frequency is 1kHz as stated on the package. All components were provided and the documents well laid out. I intend to develop this kit by building it into a box and replacing the waveform selector jumpers and level pot with a multi position switch and remote pot so it can be used as a very basic and handy signal generator in my toolbox with the output taken to a BNC connector. Nice little kit.

Super produit qui fonctionne parfaitement bien et qui est idéal pour apprendre à souder et à se servir d'un oscillo. La taille de la platine 4cm X 5.5cm ainsi que les nombreux composants qui l'équipent (34 composants), obligent à être très soigneux et à disposer d'un appareil de soudage très fin et d'un dispositif de préhension pour maintenir la platine pendant le soudage. Je recommande ce produit pour démarrer en électronique. L'intérêt de ce GBF est de pouvoir visualiser les signaux sur oscillo. Sans ce dernier on ne voit rien. La fréquence des signaux est de 1 Khz on peut donc utiliser la carte son et le logiciel idoine (gratuit) pour visualiser les signaux sur PC. Il fonctionne avec une pile de 9V non fournie.

I carefully built the signal generator and double checked each solder joint with a 10x loop. After powering it up, it provided the correct waveforms per jumper settings. I am satisfied this is a great product and enjoyed building it.

This was a fun little kit to put together. Actually not sure if it had instructions. It had a schematic and is a small board anyway so I just assembled in a logical manner. The one thing that would have gone easier is if I would have installed the pins earlier, I had to lay them on a pair of pliers to hold them up in the holes for soldering.Still, everything went pretty quickly and the pins went in vertically so I ended up with a nice looking little assembly. Checked it on my scope and all the wave forms function correctly. I thought this would be a good experience to learn more about use of a 555 timer and wave shaping circuits.Now that the kits finished I'll the real use begins as I make measurements and gain a better understanding how it works.

It's works and is OK for project but the battery life is VERY short. Tight PCB. Can be a challenge for some for a first time kit project. Typical Velleman quality.

It did the job; it is cheap and simple and small. I would recommend it to anyone with similar requirements to mine.
