DSO150 Oscilloscope Case with LiPo Battery

thingiverse

The DSO150 is a fantastic small form factor oscilloscope touted as portable, but one major flaw prevents it from being truly portable: most versions come without a battery and require an external 9V power source. Unfortunately, standard 9V batteries don't last long, making them a wasteful choice unless you invest in an expensive rechargeable one. To address this issue, I designed a custom case for my DSO150 using Thingiverse as inspiration. The design features a rechargeable LiPo battery pack instead of the traditional 9V battery. Initially, I used an old LG G6 battery, but later upgraded to a 5000mAh battery for better performance. To ensure efficient charging, I incorporated a USB-C TP4056 module and an MT3608 boost converter to step up the voltage from 3.7V to 9V. The case is held together by M2.5x30mm countersunk bolts, which are easily shortened if necessary. Future improvements include designing a stand for the oscilloscope to rest at a slight angle and adding a charging light hole for convenient monitoring. For now, users can achieve a similar effect by loosening the top bolts 0.5cm.
