Comimark Function Generators Editorial Review
The Comimark ICL8038 Function Signal Generator DIY Kit has received mixed reviews from customers, reflecting both its potential benefits for hobbyists and the pitfalls experienced during assembly and operation. Priced around $10, many users appreciate the kit as an introduction to waveform generation, particularly for those looking to refresh their electronics skills. This kit is particularly appealing to beginners or DIY enthusiasts who can tolerate a few hurdles in order to gain practical experience. Many reviewers noted that the provided instructions could be challenging to navigate, often citing them as poorly photocopied and hard to read. Users have found success seeking guidance from online resources like Instructables and YouTube, where clearer assembly instructions and schematics are available. However, the absence of a proper schematic was highlighted as a downside, possibly hindering the learning experience. Once assembled, the product does deliver usable functionality, generating sine, triangle, and sawtooth waveforms. Yet, customers pointed out significant issues with the square wave output, stating that adjustments to amplitude are not straightforward and depend directly on input voltage rather than the generator's controls. This complexity led to frustrations with achieving stable waveforms at higher frequencies, particularly over 400KHz, where the quality of the sine wave deteriorated significantly. Many users reported frequent tweaks were necessary to maintain acceptable wave quality. Despite these challenges, some users were satisfied with the overall learning experience and viewed the device as a handy tool for testing circuits, albeit not suitable as precision audio gear. The general Consensus is that while the kit is affordable and offers educational value, it requires patience and potentially extra tools or components to operate effectively. **
