[Mia] The result of an open call for dialect narration. Utilization of Coconara, Crowdworks, and Lancers

In the case of narration, many voice actors present their conditions in terms of unit price per character + unit price per file cut, and this time I set the amount a little higher than the market price respectively (3 yen per character and 10 yen per cut) as follows. The recruitment text was copied and posted on Crowdworks and Lancers as well as Coconara, and was also posted on Mia's website.

[Mia delivery] Due to the postal rate revision from 1st Oct, we have reevaluated our packaging…

The traditional packaging of individual boxes and outer boxes has been reviewed and switched to plastic packaging plus delivery bags. The new packaging weighs 130 grams and the shipping cost is now 390 yen within 150 grams. The original packaging cost 660 yen, so the delivery cost has been halved and the packaging time reduced by about 1/3!

[Mia] Want PR but not enough inventory? Reality of tightrope walking encountered in hardware

We have made a major update to Mia's functionality and we want to do a big PR campaign, but we have been plagued by a shortage problem and we have been keenly aware of the need for stock control and the psychological difficulty of PR, so we have described the stock problem. On reflection, ‘we should have moved on to the next order in a situation where we had plenty of stock’.

[ESP32] Modified circuit with power supply noise countermeasures to avoid surface mounting errors.

The MAX98357 itself needs to be connected to pins 25, 26 and 22 of the ESP32 WROOM 32E. keep the I2S signals (BCLK, LRCLK and DIN) as close as possible to pins 25 and 26 of the ESP32, as keeping the wires short reduces the risk of signal degradation and cross-talk. Attempt to optimise decoupling capacitors in the circuitry around the power supply to reduce power supply noise.

[ESP32] Investigation of the cause of cracked speaker sound and no playback due to wiring error (magnifying glass and oscilloscope)

When the IC package of the Class D amplifier was changed from TQFN to WLP, 4 out of 25 were defective in the speaker area as follows. Investigate the cause of sound crackling and audio not being played back. Verify if the sound crackling is resolved by first lowering the volume in the application. Next, using a magnifying glass, visually check for wiring defects.

[Stock issue] What if a part is out of stock when I place my order? Using JLCPCB’s pre-order.

In order to deal with out-of-stock issues like this one when they decide to order, JLCPCB allows pre-ordering, which means that the parts can be ordered before the PCB assembly is ordered and kept in stock at JLCPCB until the PCBA service is required. These pre-ordered parts are sent together with the PCB (and surface mount if you have also asked for surface mount), rather than separately from the PCB and only the parts are sent to you.

[Mia] How to set up an interactive user experience on your website.

'Wouldn't it be possible to set up a 3D model of Mia on the HP and offer an interactive user experience on the HP as well, with a 360-degree rotation for viewing, and eyes that move and talk when you nod your head?'　I came up with the idea.The part of Mia's head to be touched was made into an orange sphere (like a mandarin orange) to clearly indicate the part to be touched. The switching gif image and audio file were uploaded to the media and made a URL reference.

[Mia Shipping] Trying to optimize box size and shipping costs.

Until now, we have been dealing with intangible software products such as SaaS and apps, so we did not have to worry about delivery and packaging, but this is our first tangible product, so we have to think about packaging size and shipping costs. Trial and error with Yamato's web pick-up service and Japan Post.
